**Rumble Fish has been awarded a grant from the Stellar Community Fund (SCF #45) to build x402 on Stellar: an open-source payment facilitator and Bazaar discovery layer that lets AI agents find, price, and pay for API endpoints and MCP tools on a per-request basis, in USDC or any SEP-41 asset.**

This is our third SCF award this year. It follows the SCF #41 grant for the Soroban-first Block Explorer, [now live as Soroban Scan,](https://sorobanscan.rumblefish.dev/) and the SCF #42 grant for the [Stellar Prices API.](https://www.rumblefish.dev/blog/post/rumble-fish-grant-stellar-prices-API/) This time we were selected in the RFP Track (Developer Tooling), as one of three teams funded under the x402 Facilitator with Bazaar RFP. You can read the full round results in the [SCF #45 Round Recap.](https://medium.com/stellar-community/scf-45-round-recap-1ecf281821ab?postPublishedType=initial)

## Why AI Agents Need a Different Payment Model

The way we pay for APIs today was designed for humans. You sign up, enter a card, pick a monthly plan, and copy an API key into your config. An AI agent that needs one price quote or one contract lookup can't fill in a signup form, and a $49 monthly subscription for a single call makes no sense for either side. x402 fixes this by reviving the long-dormant HTTP 402 "Payment Required" status code. When an agent calls a paid endpoint, the server responds with payment terms. The agent signs a payment, a facilitator verifies and settles it on-chain, and the request goes through. Payment becomes part of the HTTP request itself, with no accounts or keys involved.

Stellar is a natural home for this pattern. Settlement costs around 0.0023 XLM per transaction, a fraction of a cent, which makes sub-cent pricing per request economically viable in a way it isn't on most other networks.

## What We're Building for x402 on Stellar

The project has four main parts. The facilitator implements the x402 v2 verify, settle, and supported endpoints, accepts any SEP-41 token, and sponsors network fees so payers don't need to hold XLM. The Bazaar is a discovery catalog with ranked search based on relevance, quality score, and curation, so agents can find paid services by describing what they need. An MCP-native discovery server exposes search and paid calls as tools, which means agent runtimes can discover and pay for services without custom integration code. And SDKs in TypeScript and Rust cover both buyers and sellers. The Rust seller crate will be the first seller-side Rust integration in the x402 ecosystem.

We're also adding a usage-based "upto" settlement scheme. The standard exact-price model breaks down for metered services, where the final cost depends on how many rows a query returns or how many tokens a model generates. With upto, the client authorizes a ceiling, and the server settles the actual amount used, never more. A Soroban proxy contract enforces the ceiling, expiry, and single-use nonces on-chain. We're submitting the scheme specification to the x402 Technical Steering Committee so it can become part of the protocol for every network, not only Stellar. Delivery happens in three tranches: a testnet foundation, a feature-complete release with the facilitator on pubnet and an external security audit underway, and a mainnet launch with audit findings resolved, a public conformance report listing settled mainnet transaction hashes, and a developer guide published to the Stellar Developer Docs.

## Real Services Instead of Demo Endpoints

The RFP requires example integrations. We could have built a few synthetic endpoints that return hardcoded JSON, and they would pass every test. They would also tell us very little about how the infrastructure behaves under real use. So we're gating our own production services behind x402 instead. Soroban Scan and the Prices API will both accept x402 payments through the new Rust crate, alongside a canonical Express/TypeScript reference example. Real queries from real users hit edge cases that demo endpoints never will, and the facilitator gets production traffic from day one. It also gives both projects a sustainable monetization path that doesn't depend on grant funding.

## What the Team Says

Marek Kowalski, CEO/CTO of Rumble Fish, sees this grant as the point where the team's earlier Stellar work comes together:

#### "Agents are becoming real consumers of APIs, and they need to pay for what they use without a human filling in forms. Stellar has the fees and the settlement speed to make per-request payments work. We already run production services on Stellar, so we're building this as a team that will use it every day, not as a demo."

## What This Means for the Stellar Ecosystem

Agentic payments are one of the fastest-moving areas in the industry right now, and the networks that offer the best developer experience for them will attract the services agents end up paying for. A facilitator, a discovery layer, MCP support, and SDKs in two languages give Stellar a complete stack for AI agent payments, available as open source for any team to run or build on.

For us, this completes a line of infrastructure work: an explorer that makes Soroban readable, a price API that makes asset data consistent, and now a payment layer that makes both of them, and any other Stellar service, accessible to autonomous agents.

x402 on Stellar: Rumble Fish Receives Its Third Stellar Community Fund Grant

Most enterprise blockchain projects start with the wrong question. The first technical conversation is usually about which chain to pick. Ethereum? Hyperledger Fabric? Stellar? That question is premature, and the fact that it comes first explains why so many of these systems get rewritten eighteen months after launch. The right question is: which parts of this system will change independently of each other, and does your architecture account for that?

Modular blockchain architecture, where execution, consensus, data availability, and settlement are separate, independently replaceable layers, is not a theoretical framework anymore. Layer 2 networks now account for the vast majority of Ethereum ecosystem transaction volume, with total L2 transactions growing from 135.6 million in January 2024 to over 543 million in early 2026 and daily activity consistently eclipsing Ethereum mainnet [(source)](https://arxiv.org/html/2606.22206v1). Celestia runs as a standalone data availability layer. BlackRock launched its BUIDL tokenized money market fund on Ethereum in March 2024 and by 2026 had expanded it across six chains with over $2.4 billion in assets under management [(source)](https://www.altrady.com/blog/cryptocurrency/blackrock-buidl-tokenized-treasury-2026), one of the clearest signals that on-chain institutional finance infrastructure has moved past proof of concept. The modular stack is production infrastructure. For institutions, the question is no longer whether to go modular, but where to draw the boundaries and what each boundary costs you.

## Why Monolithic Architectures Fail at Institutional Scale

A monolithic blockchain handles execution, consensus, and storage in a single system. This has one genuine advantage: simplicity. One system, one security model, one set of documentation. For an internal proof of concept or a bounded pilot, this is often the right call. **The problem surfaces when the system exits the pilot stage.**

Take a settlement system for tokenized treasury bonds. At launch, it processes a few hundred transactions per day. Compliance requires address-level KYC, counterparty whitelisting, and an immutable audit log that satisfies MiFID II. Consensus needs to be deterministic and fast; no institution will accept probabilistic finality for regulated settlement. And two years from now, **the same system needs to handle ten times the volume,** integrate with an external custody provider, and potentially expose part of its state to a public chain for regulatory transparency.

In a monolithic system, each change touches everything. A consensus upgrade may require re-auditing smart contracts. A change to the access model may conflict with settlement logic. Scaling one layer scales all of them. **In a modular system, those layers are isolated.** You can replace the execution layer without touching settlement. You can add private data availability without changing consensus. You can, and this matters specifically for institutions, audit and scale each layer on its own schedule.

## The Four Layers That Cannot Be One Decision

A practical modular blockchain architecture for enterprise separates four distinct concerns. Each has different requirements and a different rate of change.

**The execution layer** is where business logic lives: smart contracts, compliance rules, settlement calculations. This layer changes most frequently, because business requirements shift, regulations evolve, and bugs in logic need fixing. For institutions, the critical requirement is deterministic execution and the ability to formally verify contract behavior. Stellar's Soroban platform, with its WebAssembly-based execution model and constrained environment, has a meaningful advantage over the EVM here. The cost model is predictable, the execution is sandboxed, and the host environment enforces strict resource limits that reduce the surface area for unexpected behavior. That predictability matters when you're processing regulated financial instruments.

**The consensus layer** determines how network nodes agree on system state. For financial institutions, the key variables are finality time and the trust model. Probabilistic finality is not acceptable in settlement systems: a transaction that might be reversed is not a transaction you can book against. Byzantine Fault Tolerant consensus with deterministic finality, as in the Stellar Consensus Protocol, achieves finality in seconds while giving you control over who participates as a validator. That last point is underrated. Institutional settlement networks are not open networks. The ability to define the validator set, rather than inherit a public one, is often a compliance requirement.

**The data availability layer** answers where data is stored and who can read it. This is the layer that most frequently requires customization in institutional contexts. Public data availability - Ethereum, Celestia - gives you maximum transparency and censorship resistance. Private or selective data availability lets you satisfy GDPR requirements, maintain confidentiality between counterparties, and restrict access to sensitive transaction details. In practice, institutional systems often need a hybrid model: public commitments to data, with private access to transaction specifics. Designing this as a first-class layer, rather than bolting on encryption as an afterthought, is the difference between a system that scales and one that accumulates compliance workarounds.

**The settlement layer** is where value transfer becomes final and irreversible. For tokenized assets, this is frequently a separate decision from execution. You can run business logic on a private chain and record final settlement on a public ledger. This pattern is increasingly common in institutional DeFi: private execution for confidentiality, public settlement for regulatory auditability. It only works cleanly if the architecture separates these concerns from the start. Separating execution from settlement in a system that was never designed to distinguish between them means starting over.

## Where Enterprise Projects Go Wrong

The most common architectural mistake we see is treating platform selection as a substitute for architectural decisions. A team picks Hyperledger Fabric because it's "enterprise-grade," and then tries to fit their compliance, scalability, and interoperability requirements to the platform's capabilities. The result is a system that satisfies the requirements on day one but has no upgrade path. The second mistake is underestimating what "compliance layer" actually means. In financial systems, compliance is not a feature you add at the end. KYC, AML, whitelisting, audit trails, reporting - each of these affects how you design the execution layer, how you manage data access, and how you integrate with external systems. Teams that define compliance requirements after making architectural decisions almost always end up with workarounds that become technical debt. The third mistake, and probably the most expensive: designing for pilot volume instead of production volume. A monolithic system handling 500 transactions per day can look perfectly scalable. The problem appears at 500,000. **Modular architecture lets you scale execution independently of settlement and data availability,** but only if that separation is built in from the start. There is no clean path to adding it later.

A concrete example: one of the DeFi protocol architectures we worked on initially treated data availability and execution as the same layer, because in the prototype they effectively were. When the protocol needed to add privacy-preserving transaction batching for institutional counterparties, the assumption that "execution state is available state" was everywhere in the codebase. The change that should have touched the data availability layer required changes across settlement logic, indexing, and the API surface. Three weeks of work that should have been three days.

## What This Means for Architects Making the Decision Now

The practical implication of the modular approach is that platform selection becomes secondary to architectural model selection. Before you decide on Ethereum, Stellar, XRPL, or a private Fabric network, there are questions that determine which architecture makes sense at all.

**What finality time does the system require?** If the system handles regulated settlement, probabilistic finality is disqualifying regardless of a platform's other strengths.

**Who controls data access?** If compliance requires selective disclosure, transaction details visible only to authorized counterparties and regulators, you need a data availability layer that handles this natively, not through encryption bolted on top of a public ledger.

**Which layers will change in three years?** If you don't know, design the separation between them such that changing one doesn't require rewriting the others. That's the point of the separation.

**Do you need interoperability with a public chain?** Hybrid models with private execution and public settlement are increasingly common, but they require specific approaches to bridge design and key management that need to be considered at the architecture stage, not after.

Institutional blockchain adoption is accelerating because the platforms have matured to the point where these questions have concrete answers. **That platform maturity does not substitute for architectural maturity.** A system built on modular principles, with clear separation between execution, consensus, data availability, and settlement, can be scaled, audited, and evolved. A system built on an "enterprise-grade platform" without that separation will eventually become a migration project.

The teams we see doing this well make the modular decision before they make the platform decision. The teams doing it poorly pick the platform first and then spend the next two years working around what they locked in.

Modular blockchain architecture for enterprise explained: how separating execution, consensus, data availability, and settlement layers prevents costly rewrites at institutional scale.

Most enterprise blockchain projects start with the wrong question. The first technical conversation is usually about which chain to pick. Ethereum? Hyperledger Fabric? Stellar? That question is premature, and the fact that it comes first explains why so many of these systems get rewritten eighteen months after launch. The right question is: which parts of this system will change independently of each other, and does your architecture account for that?

Modular Blockchain Architecture for Enterprise: The Decision You Can't Undo Later

By mid-2026, the ZKP industry had over $3 billion in total funding deployed; zkSync Era and Starknet are serving real transaction volume, Aztec launched on mainnet, and the proving layer, once a bottleneck that made production ZK feel impractical, has crossed into viable territory thanks to specialized prover infrastructure.

This list is not a directory of everyone experimenting with ZK. It focuses on companies that have shipped: production deployments, mainnet systems, or development services with verifiable client work. There are dozens of stealth projects claiming breakthroughs in proof efficiency. Most of them don't belong here yet.

What's changed in the last 18 months is the cost and speed of proof generation. In 2024, generating an Ethereum block proof required a $300–400K GPU cluster and hours of compute time. Today, Succinct's SP1 Hypercube brings that down to around 10 seconds on 16x RTX 5090s. RISC Zero's R0VM 2.0 went from 35 minutes to 44 seconds per block. Those are the numbers that unlock the next category of applications, and the companies below are the ones building on top of that shift.

## Infrastructure: The Proving Layer

The least visible part of the ZK ecosystem is the one that makes everything else possible.

[**Succinct Labs**](https://www.succinct.xyz/) built SP1, a general-purpose zkVM running over RISC-V. Around 90% of the rollup proving market runs on SP1, including Optimism, Base, and Unichain. Their Prover Network, backed by a $PROVE token and launched in 2025 after a $55M Series A led by Paradigm, decentralizes proof generation so projects don't need to own GPU infrastructure. SP1 Hypercube is the current performance frontier: roughly 10 seconds per Ethereum block proof at around $0.02 per proof, on hardware that costs $24–48K to own rather than $300–400K.

![succinct-hp.png](https://strapi-uploads.rumblefish.dev/succinct_hp_a3a5124231.png)

[**RISC Zero**](https://risczero.com/) takes a similar zkVM approach (write Rust programs, get ZK proofs of execution) and has a different economic model. Their Boundless marketplace, live on mainnet since September 2025, has processed 542 trillion cycles and 399K orders. R0VM 2.0 dropped block proving time from 35 minutes to 44 seconds. They claim 7x lower cost than SP1, though benchmark comparisons between proving systems are notoriously dependent on workload type.

[**Irreducible**](https://www.irreducible.com/) is the one to watch for the medium term. They're building Binius, a proof system that operates over binary fields instead of the large prime fields used by most SNARKs and STARKs. The practical implication is that binary computation, which is how CPUs actually work, can be proven much more directly, targeting 10–100x efficiency improvement over prime-field proofs. Vitalik Buterin wrote a detailed explainer on it. Polygon Labs is partnering on a Binius-based zkVM. $39M raised from Paradigm and Bain Capital Crypto, and still in research-to-production development.

![irreducible-hp.png](https://strapi-uploads.rumblefish.dev/irreducible_hp_890ce6eeaa.png)

[**Ingonyama**](https://www.ingonyama.com/) is doing hardware acceleration via ICICLE, an open-source GPU acceleration library for ZK provers. If you have a proof system and want it to run faster on GPUs without rewriting your cryptography, ICICLE is the library. They're also building FPGA and custom silicon implementations. The $21M seed from IOSG, Walden Catalyst, and Samsung Next reflects a bet that proving costs will continue to drop as specialized hardware catches up.

## Rollups: The L2 Battlefield

The major zkEVM rollups are past the "will this work" phase and into the "how fast, how cheap, and for whom" phase.

[**Matter Labs**](https://matterlabs.com/) is probably the most ambitious bet in the space right now. $458M raised, and the 2026 roadmap points clearly at institutional finance. Prividium, their private permissioned blockchain for regulated financial institutions, has five U.S. banks representing over $600B in deposits building on it through Cari Network. The Elastic Chain vision (multiple application-specific ZK chains sharing a common proving layer, interoperating natively) is becoming real: ZIP-16 introduced native cross-chain token transfers between ZKsync chains in May 2026, with fees denominated in $ZK. This is no longer just a scaling play; it's infrastructure for compliant institutional DeFi.

[**StarkWare**](https://starkware.co/) invented STARK proofs and remains the only major L2 team that is also the research origin of its proof system. Starknet is the production rollup; StarkEx is the permissioned scaling engine behind dYdX, Immutable X, and Sorare. The $8B valuation from the Series D in 2022 looked aggressive at the time. What's notable is the post-quantum angle: STARKs are hash-based and carry no elliptic curve dependency, which makes them resistant to future quantum attacks in a way that SNARK-based systems are not. That argument has gotten louder as quantum computing timelines have shortened.

[**Aztec Network**](https://aztec.network/) is the one doing something the others are deliberately not doing: privacy by default. Most ZK rollups use zero-knowledge proofs for scaling: the validity proof proves the computation was correct, but the transactions themselves remain visible on Ethereum. Aztec's architecture separates private execution (done locally on the user's device via PXE) from public settlement (submitted to Ethereum). Contracts can define exactly which data is public and which stays private, and those privacy rules compose across contract calls. Mainnet launched in November 2025. The token generation event happened in February 2026. Full private smart contract execution is rolling out through 2026. Backed by a16z and Paradigm with over $180M combined equity and token rounds.

![aztec-network-hp.png](https://strapi-uploads.rumblefish.dev/aztec_network_hp_f94f59a99c.png)

[**Polygon**](https://polygon.technology/) is the largest ZK ecosystem by capital deployed, $451M in funding plus a $1B+ ZK treasury, and also the most fragmented. Polygon zkEVM is the main production rollup (sub-2.5 second confirmation, $0.015 average fee). Polygon Miden is a STARK-based VM with a distinct design philosophy. Polygon Zero uses recursive proofs. The acquisition of Toposware in 2024 and the $5M purchase of Fabric VPU hardware signals continued infrastructure investment. The risk with Polygon's ZK story is the breadth: three separate ZK product lines with different proof systems require a lot of engineering coordination to maintain and differentiate.

## Privacy Blockchain Development: Applications Layer

[**Zcash**](https://z.cash/) matters because it has ten years of production ZK-SNARK deployment, which no one else can claim. The Halo 2 upgrade removed the trusted setup requirement that had been a persistent criticism of the original Groth16 proofs. The shielded pool crossed 4.5M ZEC in late 2025. Market cap surged past $6.3B. For teams evaluating privacy blockchain development in financial contexts, Zcash is the only project with a decade-long track record of ZK proofs in production under adversarial conditions.

[**Worldcoin / World**](https://world.org/) is the largest real-world ZK deployment by user count: over 10 million people verified as unique humans via iris scan, with ZK proofs ensuring the biometric data never leaves the Orb. Whether or not you have opinions about the project's approach to identity, the engineering is real and deployed at a scale no other ZK application has reached.

## ZK Proof Services: Development Partners

Most of the companies above are building protocols, infrastructure, or applications on their own roadmap. If you're a company that wants to integrate ZK into your product (a private voting system, a confidential DeFi protocol, a compliance tool that proves regulatory requirements without exposing user data), you need a different kind of partner.

[**Rumble Fish**](https://www.rumblefish.dev/services/zero-knowledge-proof-development/) sits in this category. The Kraków-based team works across the full ZK development stack: custom circuit design using Circom, Noir, gnark, and arkworks; rollup implementations; privacy-preserving smart contracts; and integration into production systems. The work is concrete: they built a decentralized registry using zero-knowledge cryptography for Original Works, reducing ZK proof processing time significantly using RISC Zero and Rust. The ZKP service covers zk-SNARKs for shielded transactions, zk-STARKs for scalable proofs, and PLONK-based systems, which is a broader proof system coverage than most development shops maintain.

What distinguishes a ZK development partner from a ZK protocol company is scope. Protocol companies own their infrastructure and build on their own timeline. A development partner works within yours, translating a product requirement into a proof system architecture and delivering a working implementation. For teams that don't want to hire a cryptography department, this is the practical path to shipping ZKP functionality.

## How to Read This Landscape in 2026

The question of which ZKP development company to work with depends on what you're actually trying to build. If you need a production ZK rollup for Ethereum scaling, the zkEVM options (zkSync Era, Scroll, Polygon zkEVM) are mature enough to evaluate seriously on their developer experience, ecosystem, and fee structure rather than proof system stability.

If privacy is the primary requirement, not just as a side effect but as the core feature, Aztec is the only production system designed around it from the start. The privacy vs. regulatory compliance tension is real and unresolved at the protocol level, but the cryptography works.

If you're building something that generates ZK proofs as part of a larger application (not a rollup, but a compliance tool, a voting system, a confidential data product) the proving infrastructure from Succinct or RISC Zero makes self-hosted proof generation cheaper than it has ever been. Whether you build on top of that infrastructure yourself or engage a ZK development partner depends on how much cryptographic expertise you can justify building in-house.

The consolidation that has happened in the last 18 months is real. The theoretical layer is largely settled. What's left is engineering, adoption, and the slow process of proving that ZK proofs can carry the compliance and privacy requirements of regulated industries: not just in test environments, but in production, under audit, with real money moving through them.

ZKP Development Companies in 2026: Who's Actually Building

Earlier this year, Rumble Fish received a $131,200 grant from the Stellar Community Fund to build a Soroban-first block explorer. Today, that tool is publicly available at [sorobanscan.rumblefish.dev](https://sorobanscan.rumblefish.dev).

The grant announcement covered what we were going to build and why. This one covers what we actually shipped, what we learned building it, and what we want from the community now that it's live.

## What Soroban Scan Does

If you've tried to debug Soroban transactions using existing tools, you know the problem. Events show up as raw XDR. Contract invocations are unreadable without manually decoding binary data. Account history is incomplete or absent for anything Soroban-specific. For anyone who isn't fluent in the Stellar protocol's binary formats, existing explorers offer very little. Soroban Scan is built around the assumption that block explorers should be readable by developers, users, and anyone curious about what's happening on-chain, not just protocol engineers who know how to interpret XDR.

Transaction pages show Soroban invocations with decoded function names, arguments, and return values. If a transaction called a swap function with specific token amounts, you see the function name and the amounts, not a hex string. Contract pages list all invocations of a given contract with the same human-readable decoding applied across the board. Function signatures are extracted from the WASM bytecode at deployment time, which is what makes decoding possible without a separate ABI file.

Event tabs decode CAP-67 contract events into structured tables: topics and data fields presented as typed values, not opaque base64 blobs. For DeFi activity like swaps, transfers, and liquidity changes, the Event Interpreter layer generates plain-language summaries. Account pages surface Soroban-specific history: which contracts an account has interacted with, what those interactions did, and the full event trail. Global search covers transaction hashes, account IDs, and contract IDs. 

## How We Got Here

The build followed the three-tranche structure in our SCF submission. Tranche 1 was the data pipeline: Galexie running on ECS Fargate, writing LedgerCloseMeta XDR files to S3 every five to six seconds, a Rust Lambda firing on each file to parse and write to our database, and the CloudWatch monitoring stack. By the end of Tranche 1, we were ingesting live mainnet data reliably.

Tranche 2 brought the frontend and the full API surface: all REST endpoints, the React SPA with transaction, ledger, account, contract, and search pages, and the Event Interpreter that generates human-readable summaries for known DeFi protocol interactions. The staging environment at this point was showing live mainnet data with Soroban events decoded.

Tranche 3 was production hardening: load testing to p95 under 200ms at 1 million requests/month equivalent load, a security audit against OWASP Top 10, full API documentation, CI/CD via GitHub Actions, and a seven-day post-launch monitoring report. The architecture is AWS-first (Lambda, ECS Fargate, API Gateway, CloudFront), with a ClickHouse database on Hetzner that turned a projected 7 TB PostgreSQL dataset into roughly 900 MB.

One thing that was genuinely harder than the architecture docs suggested: the historical backfill. Soroban has been on mainnet since late 2023, which meant indexing roughly two years of history before going live. We ended up running the backfill on local machines writing to a local ClickHouse instance, then migrating the result to production, because the event-driven pipeline optimised for continuous ingestion is simply the wrong shape for a one-time bulk operation across millions of ledgers. 

## What We Need From You

Soroban Scan is live and stable, but no block explorer gets to call itself finished at launch. The DeFi protocol coverage in the Event Interpreter is real but limited. We're pattern-matching against Soroswap, Aquarius, and Phoenix today, and every Soroban project that builds something new is a new case to handle. Contract decoding works for contracts that embed their WASM, but the ecosystem is growing, and there will be edge cases we haven't seen.

To use Soroban Scan as a Soroban debugger: paste any transaction hash from a smart contract invocation into the search and open the detail page. The decoded function arguments, return values, and event trail are on one page. If something looks wrong, or if a transaction you'd expect to be readable isn't, that's exactly the kind of feedback we need.

Useful things to tell us: contracts or protocols where events aren't decoding correctly; transactions where the human-readable summary is wrong or missing; search edge cases where a transaction hash, account ID, or contract ID returns something unexpected; anything about the UI that makes it harder to understand what a transaction actually did.

Soroban Scan Is Live: The Soroban Block Explorer Built for the Whole Ecosystem

Every RWA tokenization platform development project starts with the same pitch: take an illiquid asset - real estate, private credit, treasury bills, invoices - and represent ownership as a token that can be split, traded, and settled on-chain. The pitch is simple. The engineering is not, and the part that trips up most teams has nothing to do with smart contracts.

Minting a token is the easy ten percent. The hard ninety percent is everything the token has to represent honestly: who's legally allowed to hold it, what happens when a regulator asks you to freeze a wallet, how the token's value stays pinned to an asset that lives entirely off-chain, and what happens the day someone wants their money back instead of their token. Get any of these wrong, and you're looking at a compliance incident or a broken peg.

This is a walkthrough of the decisions that actually shape an RWA tokenization platform, based on the tradeoffs we've navigated building them.

## Token Standard: Why ERC-20 Is the Wrong Default

The instinct on Ethereum is to reach for ERC-20. It's the standard every wallet, exchange, and DeFi protocol already understands, and for a purely fungible asset with no transfer restrictions, it would be fine. Real-world assets rarely fit that description.

A tokenized security has to enforce who can hold it: accredited investor status, jurisdictional restrictions, lock-up periods, sanctions screening, all checked at transfer time, not just at issuance. Plain ERC-20 has no hook for that. Every restriction ends up bolted on as an off-chain process the smart contract knows nothing about, so the contract will happily execute a transfer your compliance team would have blocked.

[ERC-3643 (T-REX)](https://eips.ethereum.org/EIPS/eip-3643) builds identity and transfer restrictions into the token standard itself. Every holder address links to an on-chain identity claim, verified against a registry of eligible investors, and every transfer runs through a compliance module before it settles. The restriction lives in the same place as the token logic instead of in a separate system that has to stay in sync with it.

The tradeoff is complexity. An ERC-3643 deployment involves an identity registry, a claims topic registry, trusted issuers, and a compliance contract, versus a single contract for plain ERC-20. For a platform that will actually be regulated, that complexity is the feature. We've watched teams try to ship the simple version first and bolt compliance on later. It doesn't retrofit cleanly, because the whole point of the standard is enforcing restrictions at the transfer layer itself, where a bolted-on contract was never designed to check them.

## Chain Selection: Settlement Cost Is a Business Requirement

For a security token settling a handful of times a day, Ethereum mainnet gas costs are a rounding error. For a tokenized payments rail or a platform issuing fractional shares to retail users making frequent small trades, they're the business model.

Stellar, through Soroban, runs typical token transfers for fractions of a cent with finality landing in roughly three to five seconds. That fee profile matters directly for platforms built around frequent, small-value transfers: tokenized remittances, fractional real estate with active secondary trading, stablecoin-denominated payment rails. Stellar also ships with [SEP-8 (Regulated Assets)](https://github.com/stellar/stellar-protocol/blob/master/ecosystem/sep-0008.md), a protocol-level mechanism for authorization-required and authorization-revocable assets. That gives you transfer-restriction primitives at the account level, without building an entire compliance layer from scratch the way you would on EVM chains.

XRPL offers a comparable cost and speed profile, plus native freeze and authorization flags on issued currencies, no smart contract required for the basic compliance primitives. That's attractive for simpler asset structures where you need the standard set of freeze and authorize controls and nothing more elaborate.

Ethereum and its L2s remain the default when a platform needs the deepest liquidity and DeFi composability, where the tokenized asset has to plug into lending markets, DEXs, or custody infrastructure already built for the EVM. You pay for that ecosystem depth in gas costs and settlement latency, even on an L2.

The right answer depends on which cost and composability profile matches how the asset will actually be used. A tokenized treasury bill that settles a few times a week and needs to sit as collateral in existing DeFi protocols belongs on Ethereum or an L2. A tokenized real estate platform doing frequent fractional trades among retail holders fits Stellar's fee structure far better.

## Identity and Compliance: On-Chain Claims, Off-Chain Verification

The compliance layer splits into two problems that get conflated more often than they should: verifying who someone is, and enforcing what they're allowed to do once you know.

Identity verification (KYC documents, accredited investor attestations, sanctions screening) doesn't belong on-chain. It involves personally identifiable information, it changes over time, and it needs to integrate with providers like Sumsub or Persona that were never built with blockchain in mind. That stays off-chain.

What goes on-chain is the claim itself. A trusted issuer, your KYC provider or a licensed verification partner, signs an attestation that a wallet address belongs to a verified, eligible holder, and that signed claim gets registered against the identity contract. The smart contract checks that claim without ever touching the documents behind it. This is the model both ERC-3643's identity registry and Stellar's SEP-8 authorization flags are built around: sensitive data stays off-chain, the yes/no answer sits on-chain where the transfer logic can actually use it.

The failure mode we've seen most often is teams trying to keep the on-chain and off-chain systems perfectly synchronized in real time. Don't. Design for eventual consistency instead: a claim gets issued or revoked, propagation to the chain happens within a defined window, and the transfer logic checks the claim's current state at the moment of transfer. A revoked claim should make the next transfer fail immediately, even if the revocation happened five minutes ago and the wallet hasn't tried to move funds since.

## Custody and the Peg: Proving the Token Is Worth What It Says

A tokenized asset is a claim on something that lives off-chain: a bank account, a title deed, a basket of treasuries. The token is only as trustworthy as the mechanism proving that claim is real, and this is where a lot of platforms are quietly weaker than they look.

The minimum viable version is a proof-of-reserve attestation: a custodian or auditor periodically confirms the off-chain asset backing matches the on-chain supply, published as a signed message or a Merkle root anchored on-chain. That's better than nothing, but it's a snapshot. The gap between attestations is exactly where problems hide.

A stronger design reports backing data through an oracle network on a schedule, rather than relying entirely on periodic manual attestation. [Chainlink's Proof of Reserve feeds](https://chain.link/proof-of-reserve) are the most established example: a decentralized oracle network independently verifies custodial balances and pushes that data on-chain, where the token contract can check it directly and pause minting if reported reserves fall below circulating supply. Chainlink markets this specifically as "Secure Mint": the reserve check sits inside the mint function itself, so the contract simply refuses to mint past what's backed. That turns a manually reviewed attestation into a system with an automated circuit breaker.

For real estate or private credit, where the underlying asset doesn't have a real-time price feed the way a treasury bill does, full real-time proof of reserve isn't achievable, and platforms that claim otherwise are overselling it. What you can build instead is a published valuation methodology, an independent appraiser or administrator, and a defined cadence for updating the on-chain NAV. Being explicit about what's actually verifiable on-chain builds more trust than pretending an illiquid asset has a live price feed it doesn't have.

## Redemption: The Feature Everyone Designs Last

Issuance gets the design attention. Redemption, turning the token back into cash or the underlying asset, usually gets bolted on afterward, and it's the part that determines whether holders trust the platform during stress.

The core design question is whether redemption is synchronous or queued. A tokenized money market fund backed by highly liquid treasuries can support near-instant redemption: burn the token, wire the cash, inside the settlement window of the underlying instrument. A tokenized real estate fund can't. Redemption has to queue against actual liquidity events: a property sale, a refinancing, a matching secondary buyer. The platform needs to be honest about that timeline instead of implying instant liquidity it can't deliver.

Getting this wrong cuts both ways. Overpromise liquidity the underlying asset can't support, and you end up with a run you can't honor. Underdeliver on a genuinely liquid asset and you're forcing unnecessary queuing on holders who didn't need it. The redemption mechanism should be sized to the actual liquidity profile of what's backing the token, decided at the architecture stage, not patched in after the first redemption request exposes the gap.

---

The chain constrains which compliance primitives are available natively. The token standard determines how deeply identity checks are embedded versus bolted on. The redemption design only works if the reserve verification underneath it is trustworthy enough for holders to believe the queue is real rather than a stall tactic. None of these decisions get made in isolation on a platform that actually survives contact with a regulator or a market downturn.

The tooling already exists: ERC-3643, SEP-8, Chainlink's Proof of Reserve. None of it is exotic anymore. What's still genuinely hard is choosing the right combination for the asset in front of you, and saying no to the shortcuts that look fine until the first redemption request or the first regulator inquiry arrives.

RWA tokenization platform development explained: token standards, chain selection, compliance architecture, and reserve verification for real-world assets.

Every RWA tokenization platform development project starts with the same pitch: take an illiquid asset - real estate, private credit, treasury bills, invoices - and represent ownership as a token that can be split, traded, and settled on-chain. The pitch is simple. The engineering is not, and the part that trips up most teams has nothing to do with smart contracts.

RWA Tokenization Platform Development: The Decisions That Determine Whether It Works

Ethereum and Stellar are both enormous networks with real production deployments in payments. However, they were designed around different assumptions about what "payment" means, and those assumptions surface everywhere once you start building. This is a practical comparison based on what it actually takes to ship a payment product on each. Let's dive in!

### What Each Network Was Designed For

Ethereum launched in 2015 as a general-purpose programmable blockchain. Payments are possible on Ethereum, but they were never the primary design goal. The network was built to support arbitrary computation, and payments are one application among many. That design philosophy has consequences that run through the entire stack. Stellar launched in 2014 with a narrower mandate: fast, cheap, cross-border value transfer. The native asset model, the built-in order book, the Stellar Consensus Protocol - all of it reflects the assumption that the primary use case is moving money between parties, including parties on different rails and in different currencies. Soroban, Stellar's smart contract platform, arrived later and extended that foundation without replacing it.

This distinction shapes what you get for free and what you have to build yourself. On Ethereum, you're adapting a general-purpose machine to payments. On Stellar, payments are the default path, and you extend from there.

### Transaction Costs and Finality

The fee difference between Ethereum mainnet and Stellar is not marginal. A simple ETH transfer on mainnet costs somewhere between $0.50 and $5 depending on network conditions, and during congestion it has gone above $50. An ERC-20 transfer costs more than a native transfer because it executes contract code. For any payment product where volume is high or average transaction size is modest, Ethereum mainnet fees are a structural problem, not an occasional inconvenience.

Stellar's base fee is 100 stroops, or 0.00001 XLM. At current prices, that's a fraction of a cent. The network uses fee bumping for prioritization rather than a gas auction, so costs are predictable rather than volatile. For a product processing thousands of transactions per day, the fee difference between the two networks compounds into a real infrastructure cost advantage for Stellar.

Finality follows a similar pattern. Ethereum achieves probabilistic finality: a transaction is considered settled after enough blocks have been added on top of it, which in practice means waiting several minutes for high-confidence confirmation. Stellar's consensus protocol achieves deterministic finality in 3 to 5 seconds. A transaction either made it into a closed ledger or it didn't. There is no "probably settled" state to manage. For payment applications with compliance requirements around settlement timing, that distinction simplifies a significant amount of downstream logic.

Layer 2 networks on Ethereum (Arbitrum, Optimism, Base) close the fee gap considerably. Fees on L2s are typically under a cent, and finality on the L2 itself is fast. But L2 finality and Ethereum mainnet finality are different things, and products with strict settlement requirements need to think carefully about which one they actually need. The L2 ecosystem also adds operational complexity: bridge risk, liquidity fragmentation across chains, and a developer environment that varies between rollups.

### The Asset Model and What It Saves You

One of Stellar's less-discussed advantages for blockchain payment infrastructure is its native asset model. Any account on Stellar can issue an asset, a stablecoin, tokenized fiat, a loyalty instrument, and those assets are first-class citizens on the network. The built-in decentralized exchange means that paths between assets exist automatically: a sender can pay in one currency and a recipient can receive in another, with conversion handled inside the transaction itself. This is not a DeFi protocol layered on top of the base layer; it is the base layer.

On Ethereum, building equivalent functionality requires smart contracts. A stablecoin is an ERC-20 contract. A swap between two stablecoins goes through a DEX or custom contract logic. Each additional layer adds gas cost, audit surface, and failure modes. For complex payment routing across currencies, the contract code required on Ethereum is substantially more involved than the equivalent path payment on Stellar.

Soroban extends this further. With Soroban smart contracts, you can add programmable payment logic - conditional releases, escrow, multi-party settlement - directly on top of Stellar's native asset model. A Soroban contract interacts with native Stellar assets without replacing them. You get programmability and the built-in payment primitives, which is a different architecture from Ethereum, where the asset model and the execution environment are the same thing.

### Compliance and Institutional Considerations

Payment products in regulated environments have requirements beyond raw technical performance. KYC, AML, transaction monitoring, the ability to freeze assets in response to legal orders: these are table stakes for anything handling real money in most jurisdictions.

Stellar has compliance controls at the protocol level. Regulated assets can require authorization before an account can hold or transact them. An issuer can freeze a specific account's holdings or globally freeze an asset. These controls are part of the asset model, not implemented via contract code. For an institution that needs to demonstrate asset control to regulators or auditors, the fact that these are protocol primitives rather than custom contract logic reduces implementation risk and simplifies the audit. Ethereum supports equivalent functionality through smart contract design. A well-written ERC-20 can include pause functions, blocklists, and administrative controls. The difference is that on Ethereum, you're implementing and auditing those controls yourself, while on Stellar, they're part of the protocol specification. The failure mode on Ethereum is a smart contract bug. The failure mode on Stellar is a misconfigured flag. Both are manageable, but they require different expertise and carry different audit costs.

### Where Ethereum Has the Advantage

This is not a case where one network is better for all payment use cases.

*   The Ethereum developer ecosystem is larger by an order of magnitude. Tooling is more mature, auditing firms have deeper Ethereum experience, and the pool of engineers who can be hired is bigger. For a team building from scratch without existing blockchain expertise, Ethereum has a shorter path to production.
*   DeFi liquidity lives predominantly on Ethereum and its L2s. If your payment product needs to interact with lending markets, AMMs, or yield protocols, the depth of what's available on Arbitrum or Optimism is not matched on Stellar. Soroban-based DeFi is growing, but it's early. For blockchains for DeFi with complex composability requirements, Ethereum remains the stronger environment.
*   Token distribution also favors Ethereum. USDC and USDT have large liquidity pools on Ethereum. If your users already hold stablecoins there, moving them to a Stellar-based product requires a bridging step that adds friction. For consumer-facing products where users arrive with existing balances, that friction is real.

### How to Make the Call

The right choice depends on what your payment product actually does, and a few questions tend to clarify it quickly.

**What's the expected transaction volume and average transaction size?** 

*   High volume, small transactions: Stellar's fee model is a structural cost advantage that compounds at scale.
*   Low volume, large transactions: Ethereum mainnet fees are manageable, and the ecosystem benefits may outweigh them.

**Do you need programmable logic beyond basic transfers?** 

*   Soroban handles most payment-adjacent use cases now. If your logic requires deep integration with Ethereum DeFi protocols, that tips the balance toward Ethereum L2.

**Do you have regulatory requirements around asset control?** 

*   Stellar's protocol-level compliance features reduce implementation risk in ways that matter to compliance teams and reduce audit scope.

**Where do your users and liquidity already live?** 

*   Building a new corridor from scratch: Stellar is a strong default. Plugging into an existing Ethereum-native ecosystem: the switching cost probably doesn't justify the move.

At Rumble Fish, the payment projects that have gone smoothest on Stellar share a common profile: high transaction volumes, multi-currency requirements, and institutional compliance needs. Projects where Ethereum made more sense were those where DeFi composability was central, or where the team was already deep in the Ethereum stack and rebuilding on a new network would have cost more than it saved.

For most payment applications, the comparison between Ethereum and Stellar is not about which network is technically superior in the abstract. It's about which one matches the shape of your problem. If you're working through that decision and want a second opinion from a team that has made it in production, [we're happy to talk](https://www.rumblefish.dev/contact/).

Stellar vs Ethereum: Choosing the Right Blockchain for Payment Infrastructure

Marek-Kowalski.png

Earlier this year, Rumble Fish received a $131,200 grant from the Stellar Community Fund to build a Soroban-first block explorer,  a publicly accessible tool for navigating transactions, smart contracts, accounts, and events on the Stellar network. The grant comes with a public mandate: the repository is open source, the infrastructure is reproducible, and the whole thing has to work reliably at mainnet scale.

Block explorers sound like a solved problem. They are not, at least not for Soroban. Soroban is Stellar's smart contract platform, and it produces data structures that existing explorers don't fully surface: decoded contract invocation arguments, return values, nested call trees, and CAP-67 contract events. Beyond that, the Stellar protocol produces a new binary payload, a _LedgerCloseMeta_ XDR file, every five to six seconds, containing the complete record of every change that occurred in that ledger close. You need to ingest it in near-real time, decode it, store it, and serve it through a public API before the next one arrives.

This article walks through the decisions that shaped our architecture. Some of them are conventional. A few are not. We replaced a planned 7 TB PostgreSQL database with a 900 MB ClickHouse instance. We run our backend Lambdas in Rust. We ran the historical backfill on local machines because that was the right tool for that specific job. Here is how we got there.

## Why We Don't Call Any External API

The straightforward approach to building a block explorer is wrapping an existing one. Horizon has been the standard Stellar API for years. Soroban RPC provides contract-level access. Both were options, and we rejected both of them.

**Horizon is deprecated** for the indexing use cases we need. The Stellar Foundation's own tooling has moved beyond it, and building on a deprecated API means inheriting its limitations permanently.

**Rate limits are fine until they're not.** A block explorer that depends on another service's API inherits that service's reliability ceiling. Traffic spikes on the Stellar network, exactly when users want a block explorer most, are also when upstream APIs are most likely to throttle requests.

**Soroban-specific data isn't pre-assembled anywhere.** We need decoded contract invocation trees showing nested contract-to-contract calls. We need function arguments and return values decoded from their binary _ScVal_ representation into structured, readable data. We need function signatures extracted from the WASM bytecode at contract deployment time. None of this exists in a form we can simply fetch from an existing API.

The decision to own the pipeline end-to-end was made early in the process and has not been reconsidered since. Every other architectural choice in this article follows from it. If we had accepted an external API dependency, most of what follows wouldn't have been necessary.

## **One Monorepo, Multiple Languages - The Nx Choice**

The project has eight distinct packages spanning TypeScript and Rust:  

| Package | Language | Role |
| --- | --- | --- |
| _apps/indexer_ | Rust | Ledger Processor Lambda - XDR ingestion |
| _apps/workers_ | Rust | Event Interpreter Lambda - enrichment |
| _apps/api_ | Rust | REST API Lambda |
| _apps/web_ | TypeScript | React SPA |
| _infra/aws-cdk_ | TypeScript | CDK infrastructure |
| _libs/domain_ | TypeScript | Shared explorer types |
| _libs/shared_ | TypeScript | Generic utilities |
| _libs/ui_ | TypeScript | Reusable React components |

These are not independent microservices that happen to live in the same repository, but they are genuinely coupled. The domain types the frontend uses to render a transaction are the same concepts the indexer writes to the database. A change to how we store Soroban invocations touches both the Ledger Processor and the API. The CDK stack deploys all three Lambdas and knows their artifact paths. The coupling is real; the only question is whether to make it visible or hide it across repository boundaries. We chose [Nx](https://nx.dev) to make it visible.

With Nx, _nx affected --target=build_ builds only the packages touched by a given change. On a workspace with eight packages across two languages, this matters: a change to l\_ibs/ui\_ should not trigger a Rust compilation. _nx run-many -t typecheck_ runs TypeScript type checking across all TypeScript packages in one command. The project dependency graph is explicit and visualisable - you can see at a glance that _apps/api_ depends on _libs/domain_, and that _infra/aws-cdk_ depends on nothing in the application layer but deploys everything.

The alternative (one repository per service) would have distributed the coupling across network boundaries rather than eliminated it. You would end up with shared type packages, inter-repo version pinning, and deployment coordination scripts that reinvent what a monorepo gives you for free. We have seen that pattern enough times to prefer the explicit version.

## Why We Write Our Lambdas in Rust

Rumble Fish has historically written backends in TypeScript. It is ergonomic, the ecosystem is extensive, and getting a new engineer productive in a Node.js Lambda takes hours, not weeks. For this project, we made a different choice: all three backend Lambda functions are Rust crates. Here is why.

### Cold start performance

Lambda cold starts are a function of two things: how large the deployment artifact is and how expensive the runtime initialisation is. A TypeScript Lambda ships a Node.js runtime plus your application code plus its _node\_modules_ - commonly several megabytes, sometimes significantly more. A compiled Rust Lambda is a single statically linked binary, typically under five megabytes, with no runtime to initialise. It starts in milliseconds.

For the Ledger Processor, which fires on every S3 event - roughly 17,000 times a day - provisioned concurrency is not a practical solution. Provisioned concurrency keeps instances warm, but it makes most sense for steady-state traffic, not for a function that needs to respond to an event every five seconds indefinitely. A fast cold start is preferable to paying for warmth.

### Execution speed

XDR parsing is not lightweight. Each _LedgerCloseMeta_ payload contains every transaction, every operation, every Soroban invocation, every CAP-67 event, and every ledger entry change for a complete ledger close. For an active ledger, that can mean thousands of decode operations: binary deserialisation, tree traversal, type-tagged value decoding. Rust does this with predictable memory usage, no garbage collection pauses, and throughput that is roughly an order of magnitude higher than equivalent Node.js.

Our target is under ten seconds from ledger close to database write. With the Ledger Processor in Rust, we are well inside it with headroom.

### The AI development loop

This is the argument we did not expect to be making when the project started. The Rust compiler is famously strict. Ownership violations, type mismatches, and lifetime errors all surface at compile time with precise, often instructive messages. This turns out to be highly productive when working with AI-assisted development: the agent writes code, the compiler rejects it with a specific error, the agent reads the error, and corrects it. The loop is fast and deterministic. There is no class of "it ran but produced the wrong output" error that requires runtime investigation.

With TypeScript or Python, AI-generated code can be syntactically valid and dynamically typed in ways that fail silently at runtime or produce subtly wrong results. With Rust, the compiler acts as a continuous integration step on every compilation. Errors are loud, early, and actionable.

As AI tooling has made Rust more accessible, removing much of the manual borrow-checker wrestling that historically made it a steep climb, the performance and correctness benefits have become easier to capture. We now consider it the better default for backend Lambda work, and this project is the system that shifted our thinking.

AWS supports Rust as a first-class Lambda runtime. The _lambda\_runtime_ crate, _aws-sdk-rust_, and the _cargo-lambda_ build toolchain cover everything needed from local development to deployment.

## The Ingestion Pipeline: Matching Compute to Workload Shape

The ingestion pipeline has three distinct jobs. We use three different execution models for them, because the workloads have different shapes, and applying one model to all three would have been a mistake.

```plaintext

Stellar peers
 → Galexie (ECS Fargate, continuous)
 → S3: stellar-ledger-data/ (~1 file per ledger, zstd-compressed XDR)
 → Ledger Processor Lambda (Rust, S3 PutObject trigger)
 → ClickHouse (Hetzner)
      ↑
 Event Interpreter Lambda (Rust, EventBridge every 5 min)
API Gateway → API Lambda (Rust) → ClickHouse (Hetzner)
CloudFront  → React SPA
```

### Galexie on ECS Fargate

Galexie is the Stellar Foundation's tool for streaming canonical ledger data. It connects to Stellar network peers via an embedded Captive Core process, maintains a persistent connection, and exports one _LedgerCloseMeta_ XDR file to S3 for each ledger close - roughly every five to six seconds, indefinitely.

Lambda is the wrong shape for this. Galexie is a long-running, stateful process. It maintains a peer connection across ledger closes, tracks which ledger it last exported, and resumes from that checkpoint on restart. Lambda has a fifteen-minute execution limit and no concept of resumption. ECS Fargate gives us a managed container runtime - one task, always running, no EC2 to provision or patch.

### Lambda (Rust) for the Ledger Processor

When Galexie writes a file to S3, an S3 PutObject notification triggers the Ledger Processor Lambda. This is the primary ingestion worker, and it is exactly the shape that Lambda is designed for: one event, one bounded unit of work, invoked per ledger close, completing in well under ten seconds.

The Lambda downloads and decompresses the XDR file, parses every entity it contains, and writes structured records to ClickHouse in a single operation. If the Lambda fails, Lambda retries automatically. If there is a permanent failure, the file remains in S3 and we can replay any ledger by re-triggering the Lambda with its S3 key.

That replayability is the reason S3 is the handoff between Galexie and the Ledger Processor, rather than a direct invocation or a queue. A durable artifact per ledger close means the ingestion pipeline can recover from failures, schema migrations, or bugs in the parsing logic by replaying affected ledgers without re-ingesting from the network.

### Lambda (Rust) for the Event Interpreter

A third Lambda fires every five minutes via EventBridge. It reads recently stored Soroban events and pattern-matches against known DeFi protocols - Soroswap, Aquarius, Phoenix - to generate human-readable summaries: "Swapped 100 USDC for 95.2 XLM."

This lives in a separate Lambda from the Ledger Processor deliberately. Our interpretation heuristics improve over time as we recognise new protocols and refine existing patterns. Keeping enrichment separate from ingestion means we can update interpretation logic, redeploy the Event Interpreter, and re-run it over historical events, all without touching the ingestion path.

## The Historical Backfill: When Architecture Meets Reality

Soroban launched on the Stellar mainnet in late 2023. Our explorer needs to surface data from the beginning, which means indexing roughly two years of history before going live. The design called for a separate ECS Fargate task to read from Stellar's public history archives and feed data through the same S3 → Lambda → ClickHouse pipeline as live ingestion; one code path for both problems, clean separation, no special cases.

We did not do that. Instead, we ran the backfill on local machines, writing directly to a local ClickHouse instance. Once the backfill was complete, we migrated the data to production ClickHouse on Hetzner. 

There were two reasons for that approach: speed and cost. The event-driven pipeline is optimised for steady, continuous work - one ledger at a time, one S3 event at a time, with the overhead of Lambda invocations, S3 round-trips, and network hops to the database. That overhead is trivially small for live ingestion, where a new ledger arrives every five seconds. For a one-time bulk operation across millions of historical ledgers, the same overhead becomes the bottleneck. A local machine writing directly to a local database processes historical data at a rate that the serverless pipeline cannot match.

Cost follows the same logic. Lambda invocations, S3 data transfer, and remote database writes during a multi-week bulk ingest all accumulate. Running on hardware you already own costs nothing beyond electricity.

The lesson is straightforward: the event-driven architecture is the right shape for what it was designed for - continuous, low-latency, per-ledger ingestion. It is not the right shape for a one-time bulk operation. Treating the backfill as its own case is the architecture working as intended.

## ClickHouse on Hetzner: Why We Left AWS for the Database

When we designed the database schema in PostgreSQL and tested it against a batch of ledgers, the extrapolated storage size for the full Stellar history came to approximately 7 TB. The same data in ClickHouse takes roughly 900 MB.

ClickHouse is a columnar database. Instead of storing rows, all fields for a given record are adjacent in storage, it stores columns, all values for a given field adjacent. For blockchain data, this is a significant advantage. Account IDs, contract addresses, operation types, ledger sequences, and status codes repeat millions of times across the dataset. Column-adjacent storage lets the compression algorithm - LZ4 or ZSTD per column - exploit that repetition far more aggressively than a row-oriented layout allows. The result is storage that is not marginally smaller but categorically smaller: a dataset you would otherwise manage in terabytes fits comfortably in gigabytes.

Beyond compression, ClickHouse's columnar layout is naturally suited to the queries a block explorer serves. Every page is some form of time-range scan: recent transactions, recent invocations of a contract, event history for a ledger sequence range. Columnar databases read only the columns a query touches, which, for range scans over a subset of fields, is substantially less I/O than a row store that reads entire rows.

**Why not DynamoDB?** DynamoDB is optimised for single-row lookups at a very large scale. A block explorer's queries, all invocations of contract X ordered by ledger, all transactions from account Y in the last thirty days, aggregate event counts by type, are not single-row lookups. Modelling them efficiently in DynamoDB would require denormalising every read pattern at write time. With a query surface as wide as ours, that is an ongoing maintenance burden every time the frontend adds a new page.

**Why Hetzner?** ClickHouse is not available as a managed service on AWS. Running it on Hetzner gives us a dedicated server with NVMe storage at a fraction of the cost of an equivalent managed database instance. Hetzner's pricing is particularly favourable for storage-heavy analytical workloads.

This makes our architecture hybrid: compute on AWS (Lambda, ECS Fargate, API Gateway, CloudFront) and database on Hetzner. The Lambda runtime does not care which cloud the database lives in. The connection is a standard TCP connection to a ClickHouse HTTP interface, the same way any other client would connect. Keeping everything under one vendor's roof is a convenience, not a technical requirement, and in this case, it was a convenience we traded for a 7 TB reduction in storage.

## CDK in TypeScript: Infrastructure in the Monorepo

All infrastructure is defined in AWS CDK using TypeScript, in _infra/aws-cdk_ inside the same Nx monorepo as the application code. The concrete benefit is that the same language, the same toolchain, and the same compiler that validates the application also validates the infrastructure. Environment names are typed constants shared across CDK and application code. S3 bucket key formats are defined once. A misconfigured Lambda environment variable that references a non-existent secret name fails at _cdk synth_ rather than at runtime.

One choice worth being explicit about: GitHub Actions authenticates to AWS using OIDC rather than long-lived credentials. The Actions workflow assumes a scoped IAM role at deploy time; no AWS keys are stored in GitHub secrets. For a public repository, this is not optional - any credential committed to a public repo is compromised immediately. OIDC eliminates the credential management problem at its source.

The CDK stack is fully reproducible. The design intention from the beginning was that anyone - including the Stellar Foundation or any other team in the ecosystem - should be able to clone the repository and _cdk deploy_ a complete working copy of the system in a fresh AWS account. The architecture is public infrastructure, not proprietary tooling.

## What We Would Do the Same Way Again

The Soroban block explorer is past Milestone 1 - historical backfill complete, live ingestion running, indexing the Stellar mainnet in real time and looking back at the architectural choices, a few stand out as clearly right.

**Owning the pipeline.** The decision to ingest directly from the canonical ledger rather than wrapping an external API has paid for itself many times over. We control what data we store, how we store it, and how we serve it. There is no upstream reliability dependency, no rate limit, and no undocumented behaviour we cannot inspect.

**Rust for Lambdas.** The cold start performance is real, the XDR parsing throughput is real, and the AI development loop has been a genuine productivity multiplier. We would make the same choice again, and we expect to make it on future projects.

**Nx for the hybrid monorepo.** Coupling between frontend, backend, infrastructure, and shared libraries is not something you can wish away by splitting into multiple repositories. Making it explicit, making it visible, and tooling around it has made the codebase easier to navigate and the CI pipeline faster to run.

**ClickHouse on Hetzner.** Seven terabytes versus nine hundred megabytes is not a marginal improvement. It is a different order of infrastructure, and once we saw that number, we did not seriously consider the alternative.

**The pragmatic backfill.** Running history on local machines and migrating the result was the right call. The elegant solution and the correct solution are not always the same.

A detailed technical deep-dive into Rumble Fish's Soroban block explorer architecture, explaining key decisions including Rust Lambdas for performance, ClickHouse over PostgreSQL reducing storage from 7TB to 900MB, and building a complete XDR ingestion pipeline independent of external APIs.

Serverless at the Edge of a Blockchain: Architecture Decisions Behind Our Soroban Explorer

We're excited to announce that Rumble Fish has been awarded a $55,000 grant from the Stellar Community Fund (SCF #42) to build a Prices API - a unified, standardized data infrastructure layer for real-time and historical price information across all Stellar assets, both classic and SEP-41 Soroban tokens.

This is our second grant from the Stellar Community Fund, following the $131,200 award from SCF #41 to build the Soroban-first Block Explorer. Together, they reflect a clear direction: Rumble Fish is here to build the infrastructure that makes the Stellar ecosystem stronger, more transparent, and more developer-friendly.

## What Problem Are We Solving?

Today, price data on Stellar is scattered. Different applications pull from different sources, use different formats, and cover different assets, creating a fragmented landscape that makes life harder for everyone building on the network. For a DeFi protocol, this means unreliable inputs that can affect the accuracy of trades and liquidity calculations. For a portfolio tracking tool, it means incomplete or inconsistent data that erodes user trust. For a developer building anything price-sensitive, it means spending weeks solving an infrastructure problem that should already be solved.

The Prices API is built to eliminate that fragmentation, providing a single, standardized source of price data covering all Stellar assets, both classic and Soroban-based.

## What the Team Says

Marek Kowalski, CEO of Rumble Fish, sees the Prices API as a natural complement to the team's broader work in the Stellar ecosystem:

#### "Price data is one of those things that every serious DeFi application needs, but that nobody wants to build from scratch. The fragmentation on Stellar today creates real friction for developers. With this API, we're building something that can become shared infrastructure for the whole ecosystem."

## What This Means for the Stellar Ecosystem

Price data infrastructure might not be the most visible part of a blockchain ecosystem, but it's one of the most critical. Every DeFi protocol, every analytics dashboard, every portfolio application depends on it. When that layer is fragmented and unreliable, the applications built on top of it suffer - and so does adoption.

By delivering a unified Prices API with 8+ years of historical coverage, real-time ingestion, and production-grade reliability, Rumble Fish is giving Stellar developers a foundation they can actually build on. The kind of infrastructure that turns good ideas into real products. You can explore the full architecture documentation on [GitHub](https://github.com/rumblefishdev/stellar-scf-submissions/blob/master/prices-api-design-after-2nd-review.md) and track the project's progress on the [Stellar Community Fund](https://communityfund.stellar.org/submissions/rec0QBqMONJbGabzq).

A press release announcing Rumble Fish's second Stellar Community Fund grant of $55,000 to build a unified Prices API for real-time and historical price data across all Stellar assets, solving ecosystem fragmentation and providing critical DeFi infrastructure for developers.

We're excited to announce that Rumble Fish has been awarded a $55,000 grant from the Stellar Community Fund (SCF #42) to build a Prices API - a unified, standardized data infrastructure layer for real-time and historical price information across all Stellar assets, both classic and SEP-41 Soroban tokens.  
This is our second grant from the Stellar Community Fund, following the $131,200 award from SCF #41 to build the Soroban-first Block Explorer. Together, they reflect a clear direction: Rumble Fish is here to build the infrastructure that makes the Stellar ecosystem stronger, more transparent, and more developer-friendly.

From Block Explorer to Prices API: Rumble Fish Receives Its Second Stellar Community Fund Grant

We're thrilled to announce that Rumble Fish has been awarded a **$131,200 grant** from the **Stellar Community Fund** (SCF #41) to build a **Soroban-first Block Explorer,** a tool designed to bring full transparency to the Soroban smart contract ecosystem on the Stellar network.

## What Is the Stellar Community Fund?

[The Stellar Community Fund](https://communityfund.stellar.org/) is an initiative by the Stellar Development Foundation that supports developers, startups, and companies building on Stellar and Soroban. Each funding round allocates resources to projects that strengthen and grow the ecosystem. Being selected is both a validation of technical capability and a signal of trust from one of the most established names in blockchain infrastructure.

## Why Does Soroban Need Its Own Block Explorer?

**Soroban is Stellar's smart contract platform** - the layer that enables decentralized finance (DeFi), collectibles trading, and a new generation of on-chain applications. While classic Stellar assets have solid support across existing block explorers, Soroban has been significantly underserved.

Current block explorers display Soroban events and transactions in raw, technical formats - often unreadable to folks without deep protocol knowledge. This creates friction for everyone: developers debugging contracts, investors tracking DeFi activity, and users simply trying to understand what an application did with their funds. A block explorer that displays Soroban operations in human-readable, context-rich formats improves the user experience and builds trust, both of which are essential to driving further adoption.

## What Are We Building?

**The Soroban-first Block Explorer** is a full-stack infrastructure project, delivered in three phases.

The first phase, the MVP, focuses on ingesting and indexing all on-chain data: ledgers, transactions, Soroban smart contract invocations, and CAP-67 events, stored in a PostgreSQL database and served via a NestJS API. The second phase brings that data to life through a public React-based frontend with transaction detail pages, account views, contract pages, and global search - all displaying live mainnet data, with Soroban events decoded into clean tables rather than raw XDR. The third and final phase is a production-grade deployment: security-audited, load-tested (targeting p95 response times under 200ms), fully documented, and monitored, ensuring reliability from day one.

The entire architecture runs on AWS, with infrastructure-as-code via AWS CDK and CI/CD through GitHub Actions.

## What the Team Says

Marek Kowalski, CEO/CTO of Rumble Fish, sees this grant as a natural next step for the company's presence in the Stellar ecosystem:

#### _“Soroban is where the most exciting things on Stellar are happening right now - DeFi, new token standards, complex smart contract interactions. But if users and developers can't clearly see what's going on-chain, adoption stalls. We're building this block explorer because the ecosystem needs it, and because **it's exactly the kind of infrastructure challenge our team is built for**.”_

## What This Means for the Stellar Ecosystem

Block explorers are often the first point of contact between a user and a blockchain network. They're how you verify a transaction went through, how a developer confirms a smart contract behaved as expected, and how an investor tracks on-chain activity. When that tool doesn't fully support the newest and most powerful features of a network, the whole ecosystem pays the price.

By building a Soroban-first block explorer, Rumble Fish is filling a critical gap - one that will **make Stellar more accessible, more transparent, and more compelling** for the next wave of builders and users entering the space.

Rumble Fish Awarded a Grant by Stellar Community Fund to Build Soroban-First Block Explorer

In the rapidly evolving landscape of digital trust, one of the most pressing challenges businesses face is surprisingly paradoxical: how do you prove something without revealing the information that proves it? For years, companies have been forced to choose between privacy and verifiability - exposing sensitive data to auditors, partners, or regulators just to demonstrate compliance or eligibility. But that trade-off is quickly becoming obsolete. Zero-knowledge proofs (ZKPs) are emerging as one of the most powerful cryptographic tools of our era, enabling businesses to verify facts without disclosing the underlying data at all.

In today's post, we take a close look at how ZKPs work, where they're already creating real business value, and what it takes to implement them right. Here's the content breakdown:

*   What is a zero-knowledge proof?
*   Must-know ZKP stats
*   Where ZKPs are delivering real-world results
*   What challenges should you be prepared for?
*   Why the team behind your ZKP project makes all the difference

## What Is a Zero-Knowledge Proof? A Business-First Explanation

Picture this: your company needs to prove to a financial regulator that your transaction volumes meet a specific threshold - without exposing your full transaction history. Or imagine a healthcare provider needing to confirm a patient's eligibility for a clinical trial without sharing any personal medical records. These aren't hypothetical scenarios. **They're exactly the kind of problems ZKPs were built to solve.**

At its core, a zero-knowledge proof is a cryptographic method that allows one party - the prover - to demonstrate to another party - the verifier - that a statement is true, without conveying any information beyond the truth of that statement itself. The technology maintains three fundamental properties: **completeness** (valid proofs are always accepted), **soundness** (invalid proofs are always rejected), and **zero-knowledge** (no information beyond the validity of the statement is ever revealed).

The most common ZKP variants businesses encounter today are **zk-SNARKs (Succinct Non-interactive Arguments of Knowledge) and zk-STARKs (Scalable Transparent Arguments of Knowledge).** Both allow for the verification of complex computations off-chain, with only a compact cryptographic proof submitted to the blockchain - making them invaluable for applications that demand both privacy and scalability.

## Must-Know ZKP Stats: The Numbers Behind the Technology

Let's start with some numbers to put the momentum behind ZKPs in perspective. The global zero-knowledge proof market, valued at approximately $1.28 billion in 2024, is projected to reach $7.59 billion by 2033, growing at a compound annual rate of 22.1% [(Grand View Research)](https://www.grandviewresearch.com/industry-analysis/zero-knowledge-proof-market-report). **This isn't just a niche blockchain phenomenon** - the BFSI (banking, financial services, and insurance) sector currently accounts for the largest share of ZKP adoption, followed by government, healthcare, and retail.

![Tables (2).png](https://strapi-uploads-staging-aldnr.rumblefish.dev/Tables_2_0de099d419.png)

Perhaps even more striking: as of 2025, the Ethereum Layer 2 ecosystem - powered largely by ZK rollup infrastructure - reached a peak of $47 billion in Total Value Locked in October 2025 [(L2Beat)](https://l2beat.com/scaling/summary). ZK rollups specifically account for around $3.3 billion of that, with the broader L2 ecosystem built on top of ZK-proof security guarantees continuing to grow rapidly. That's not research funding or venture capital, that's real capital sitting in operational systems right now. And the ZK-based KYC market alone is growing at 40.5% CAGR, **from $83.6 million in 2025 to a projected $903.5 million by 2032** [(Stratistics MRC)](https://www.strategymrc.com/report/zero-knowledge-kyc-market). That last figure is particularly significant for companies dealing with identity and compliance. It tells you where the industry is heading before the regulatory mandates arrive.

![Tables (1).png](https://strapi-uploads-staging-aldnr.rumblefish.dev/Tables_1_3f7559be24.png)

## Where ZKPs Are Delivering Real-World Results

### Financial Services and DeFi: Privacy at Scale

The financial sector has become the most active proving ground for ZKP technology - and for good reason. **Financial institutions need to verify transaction authenticity and customer credentials without exposing sensitive data.** That's precisely what ZKPs enable at scale. Take Loopring, a decentralized exchange built on ZK rollups. During periods of severe Ethereum network congestion in 2024, when mainnet transaction fees exceeded $50 per transaction, Loopring users continued trading with fees under $0.50, maintaining identical security guarantees while achieving near-instant execution. A quantitative trading firm that migrated to Loopring reported **a 94% reduction in monthly trading costs,** transforming previously unprofitable high-frequency strategies into viable operations.

Similarly, when Aave, one of the largest DeFi lending protocols, deployed on Scroll (a ZK-powered Layer 2), the migration required zero contract modifications. Integration took hours instead of the weeks typically required for other Layer 2 solutions, and **users experienced transaction cost reductions of over 95% with no change to the interface or functionality.**

#### Real-Life Use Case: Private Payroll and B2B Payments

In September 2025, Aleo Network integrated with Request Finance to enable confidential on-chain payroll and vendor payments using zero-knowledge cryptography. Companies can now conduct compliant business transactions, including employee payroll, on-chain while maintaining full data privacy. This solves a problem that has blocked many enterprises from adopting blockchain-based financial infrastructure: the tension between regulatory compliance and business confidentiality.

### Identity Verification: Prove Who You Are Without Showing Who You Are

Traditional KYC processes force users to hand over passports, utility bills, and financial statements to multiple parties, creating enormous data liability on both sides. ZKP-based identity systems fundamentally reframe this interaction. With zero-knowledge decentralized identifiers, a user can prove they're over 18, a resident of a specific country, or an accredited investor without revealing their birthdate, address, or account balance. The credentials are stored by the user themselves, and each proof discloses only the minimum required information. For DeFi platforms that need to enforce regulatory requirements, **this unlocks a path to compliance without custodial data collection.**

Aztec Network, backed by $100 million in funding led by a16z crypto, is building what it describes as the first hybrid ZK rollup, combining private transaction encryption with ZK-proof compression. The result: fully private smart contracts on Ethereum, where business logic can execute without exposing any underlying data to other network participants.

### Supply Chain and Carbon Markets: Verifying Without Exposing

Supply chains present a particularly rich opportunity for ZKPs. Companies are routinely required to share supplier data, sourcing information, and logistics records with partners, auditors, and regulators - data that also happens to represent their most valuable competitive intelligence. **ZKPs allow businesses to share verified insights without giving competitors a window into their operations.**

In the carbon credit market, this problem has reached critical proportions. Senken's decentralized carbon marketplace uses ZKPs to enable end-to-end accountability for authentic carbon credits, allowing enterprises to verify the provenance of credits they purchase privately, and publish their carbon consumption and savings data, without exposing commercial relationships. With over 100 high-quality carbon projects on the platform, ZKPs are helping bridge the gap between a supply of 400 million tonnes and demand of 420 billion metric tonnes, in a market plagued by authenticity concerns.

### Intellectual Property Management: A Rumble Fish Case Study

One of the most technically ambitious real-world ZKP deployments we've built ourselves demonstrates just how transformative this technology can be when implemented by a team that genuinely understands both the cryptography and the business context.

#### Real-Life Use Case: Original Works — Decentralized IP Registry

Original Works, a foundation incubated by Revelator (a leader in music rights management and digital distribution), needed to bring the DDEX standard (the global protocol for exchanging music metadata between labels, distributors, and publishers) onto the blockchain. The challenge: DDEX messages use a complex XML format with over 50,000 lines of validation rules. Validating these on-chain was computationally impossible within Ethereum's gas limits.

[Our team at Rumble Fish engineered a bespoke network of ZK-powered validators](https://www.rumblefish.dev/case-studies/decentralized-ddex-registry-original-works/) using the RISC Zero virtual machine, writing validation logic in Rust and generating zero-knowledge proofs for each XML file's correctness. The initial proof generation time was 16 hours per file - far too slow for a system processing thousands of messages daily. Through rigorous optimization, including GPU acceleration and preprocessing raw XML into JSON, **we cut proof generation time from 16 hours to just 3 minutes.**

The result: a fully decentralized, tamper-proof, and automated system for validating and registering music IP metadata, with complete auditability and no centralized point of failure. "The innovative solutions developed by the Rumble Fish team were instrumental in overcoming the complex challenges of bringing DDEX metadata to the blockchain," said Gilad Woltsovitch, Co-Founder of Original Works. “This collaboration exceeded all our expectations.”

## What Challenges Should You Prepare For?

That said, zero-knowledge proof development comes with unique challenges that can become serious bottlenecks if your implementation team doesn't have deep, hands-on experience with the technology. Here's where things get genuinely complex.

*   **Computational intensity.** Generating ZK proofs, particularly for complex computations, can be extremely resource-heavy. Our Original Works project is a clear example: raw proof generation took 16 hours before systematic optimization brought it to 3 minutes. Without the right expertise in hardware acceleration, zkVMs, and proof system selection, teams can find themselves with technically correct but operationally impractical systems.
*   **Trusted setup requirements.** Some ZKP schemes (notably zk-SNARKs) require a trusted setup ceremony - a multi-party computation process that generates the initial cryptographic parameters. If this process is compromised, the entire system's integrity is at risk. Managing this correctly demands specialized cryptographic knowledge that goes well beyond standard blockchain development.
*   **Circuit design complexity.** In ZKP systems, the computation you want to prove must be expressed as an arithmetic circuit, a highly specialized representation that requires deep expertise in both the target problem and the underlying cryptographic machinery. Errors in circuit design can introduce subtle vulnerabilities that are difficult to detect and costly to fix post-deployment.
*   **Integration with existing systems.** Most enterprise environments have established data formats, workflows, and compliance requirements, like the DDEX XML standard in our Original Works project. Integrating ZKP systems with legacy infrastructure without disrupting existing operations requires both cryptographic and systems engineering expertise working in close coordination.

Gaining a competitive edge with ZKPs requires understanding, predicting, and planning for these obstacles from day one. The good news is that with the right team, none of them are insurmountable.

## Why the Team Behind Your ZKP Project Makes All the Difference

Here's where the stakes become very real for CTOs and technical decision-makers. **Zero-knowledge proof development sits at the intersection of cutting-edge cryptography, blockchain engineering, performance optimization, and domain expertise.** It is not a space where generalist blockchain developers can improvise their way to production-quality results.

The difference between a team that has shipped ZKP systems in production and one that is learning on your project is measured not in code quality metrics, but in 16-hour proof generation times versus 3-minute ones. In systems that hold up under real transaction volumes versus those that collapse under load. In security models that are mathematically sound versus those that appear correct but harbor subtle vulnerabilities. And we all know that being the first to bring a privacy-preserving product to market in your sector builds a massive competitive advantage, particularly in financial services, healthcare, and supply chain, where data privacy is rapidly becoming a regulatory baseline, not a differentiator.

**What to look for in a ZKP development partner:**

*   **Production track record** - not just research papers or proof-of-concepts, but shipped systems operating under real load
*   **Protocol agnosticism** - the ability to select the right ZKP scheme (SNARKs, STARKs, or hybrid approaches) for your specific use case, not a single preferred tool
*   **End-to-end ownership** - from cryptographic protocol design through backend proving services, smart contract verification, and frontend integration
*   **Deep familiarity with zkVMs** (like RISC Zero) and performance optimization, especially GPU acceleration for proof generation
*   **Honest, engineering-first communication** with realistic timelines

## The Window Is Open - But Not Forever

In the early days of blockchain, ZKPs were a subject for academic papers and cryptography conferences. Today, they are live infrastructure securing tens of billions of dollars of value, enabling private enterprise transactions, and powering the next generation of identity and compliance systems. **The technology has been battle-tested, the tooling has matured dramatically, and the business case has never been clearer.** The question for technology leaders is no longer whether zero-knowledge proofs are ready for production. They are. The question is whether your organization will be among those that capture the privacy, scalability, and compliance advantages of this technology in the next 12 to 24 months - or whether you'll be playing catch-up to competitors who moved sooner.  
If you're evaluating ZKP adoption for your platform or exploring what a privacy-preserving architecture could look like for your specific use case, our team at Rumble Fish has the production experience to help you move from concept to deployment with confidence.

A comprehensive business guide to zero-knowledge proofs in 2026, covering real-world applications in finance, identity, and supply chain, with a detailed Rumble Fish case study on Original Works' decentralized IP registry reducing proof generation from 16 hours to 3 minutes.

In the rapidly evolving landscape of digital trust, one of the most pressing challenges businesses face is surprisingly paradoxical: how do you prove something is true without revealing the information that makes it true? For years, companies have been forced to choose between privacy and verifiability - exposing sensitive data to auditors, partners, or regulators just to demonstrate compliance or eligibility. But that trade-off is quickly becoming obsolete. Zero-knowledge proofs (ZKPs) are emerging as one of the most powerful cryptographic tools of our era, enabling businesses to verify facts without disclosing the underlying data at all.

Zero-Knowledge Proofs in Action: How Businesses Are Turning Cryptographic Theory into Competitive Advantage

The blockchain industry has moved well past its "experimental" phase. With the global blockchain market valued at $32.99 billion in 2025 and projected to reach $393.45 billion by 2030, a staggering CAGR of 64.2% according to MarketsandMarkets, the question for most technology-forward businesses is no longer whether to build on blockchain, but with whom. That decision carries real consequences. Picking the wrong development partner means misaligned architecture, smart contract vulnerabilities, costly rewrites, and, perhaps most painfully, missed market windows. The right partner, by contrast, doesn't just write code. They own the complexity on your behalf, anticipate protocol-level pitfalls before they become production incidents, and build systems that scale as the ecosystem itself evolves. In this post, we break down the top blockchain development companies to consider in 2026 - what they specialize in, where they excel, and which type of project they're best suited for.

Here's what we cover:

*   What to look for in a blockchain development partner
*   The top blockchain development companies in 2026
*   How to match your project requirements to the right vendor

## What Separates a Good Blockchain Development Company from a Great One

Before diving into the list, it's worth establishing the criteria. Technical skills are the baseline; any credible vendor will claim Solidity expertise and multi-chain experience. What actually differentiates the best firms goes deeper.

*   **Protocol breadth and depth.** In 2026, multi-chain is the standard, not the exception. Layer-2 solutions like Arbitrum and Optimism, cross-chain interoperability tooling, and enterprise frameworks like Hyperledger Fabric and R3 Corda all serve distinct use cases. **A vendor locked into a single ecosystem is a vendor that will eventually constrain your architecture.**
*   **Full-cycle ownership.** There's a significant difference between a team that executes specifications and a team that co-owns the product development process. The best blockchain development companies conduct business analysis, architect proofs-of-concept, manage deployment, and provide post-launch maintenance - all under one roof.
*   **Security-first methodology.** Smart contract vulnerabilities are not recoverable mistakes. Rigorous audit processes, formal verification where appropriate, and a development culture that treats security as a design constraint rather than a final checklist item are non-negotiable for production-grade systems.
*   **Compliance readiness.** With the EU's MiCA regulation now in effect and U.S. digital asset legislation advancing, compliance-aware architecture has become a critical differentiator, especially in DeFi, RWA tokenization, and financial infrastructure.

With those criteria in mind, here are the companies that consistently meet the bar in 2026.

## The Criteria That Matter Most in 2026

The blockchain development market is maturing rapidly. The gap between firms that produce working smart contracts and firms that deliver production-grade, compliant, maintainable blockchain infrastructure is widening - and the cost of that gap, measured in audit findings, protocol migrations, and missed regulatory deadlines, is rising accordingly. When evaluating any vendor on this list or beyond it, ask for live project references, not just case studies, and specifically ask about post-deployment experience. The firms that remain genuine partners after launch, adapting architecture as the ecosystem evolves, are the ones that deliver compounding value over time.

If your roadmap includes blockchain development in 2026 and you're looking for a team that can own the technical complexity from day one, [reach out to the Rumble Fish team](https://www.rumblefish.dev/contact) - they'll tell you quickly whether your project is a strong fit and what the right architecture looks like.

If you're building AI models, running software tests, or navigating the maze of data privacy compliance, you've probably run into the same wall: the data you need is either locked away, too expensive to collect, or legally off-limits. Synthetic data generation is how the smartest teams are breaking through that wall - and in this guide, we'll show you exactly how it works.

Synthetic data generation is the process of creating artificial datasets that replicate the statistical properties, patterns, and correlations of real-world data without incorporating any actual individual records or sensitive information. This technology has become essential for organisations navigating the intersection of data-driven innovation and privacy compliance. At Rumble Fish, we've seen this challenge play out across DeFi protocols, fintech platforms, and AI-powered products. Whether you're simulating on-chain transaction behaviour, generating training data for ML models, or stress-testing a financial system, synthetic data is no longer a workaround - it's a battle-tested strategy.

 **TL;DR** 

Synthetic data generation uses algorithms, statistical models, and AI techniques to create artificial data that preserves the statistical properties of real data while eliminating privacy risks. The generation process analyses original data patterns and recreates them as entirely new data points that contain no traceable personal information.

## Understanding Synthetic Data Generation

Synthetic data generation refers to **creating artificial data that maintains the utility and statistical characteristics of existing data** without exposing sensitive production data. This artificially generated data serves as a privacy-preserving alternative for AI training, test data generation, analytics, and simulations across industries. For modern software development teams, the ability to generate synthetic data solves several critical problems: data scarcity in underrepresented scenarios, privacy restrictions on production data access, and the high costs of acquiring and labelling real data. Data scientists can train robust machine learning models, run load and performance tests, and develop new features without ever touching actual sensitive information.

### Types of Synthetic Data

**Structured synthetic data** includes tabular data, relational database records, and financial transaction logs. This type is particularly valuable for fintech applications where generating realistic tabular data enables fraud detection model training and payment system testing without exposing real customer data to risk.  
**Unstructured data** encompasses images, text, audio, and video generated through deep learning models. Natural language processing applications benefit from synthetic text that mimics real communication patterns, while computer vision systems train on generated images representing scenarios difficult to capture in production.  
**Time-series synthetic data** covers sensor readings, transaction logs, market data, and sequential events. For blockchain and DeFi applications, this includes simulated on-chain activity, protocol interactions, and smart contract transaction patterns that would be impossible to collect at scale from live networks.  
Each type connects to specific development needs: structured formats support database testing and analytics, unstructured formats enable AI model training, and time-series data powers simulation and performance testing.

### Synthetic vs. Real vs. Anonymised Data

Traditional anonymisation techniques - data masking, tokenisation, generalisation - modify real data to obscure identities. However, these approaches carry re-identification risks when combined with external datasets, and often degrade data utility by removing the contextual information essential for analysis. Synthetic data fundamentally differs because **it contains no actual data from real individuals**. The generator creates data that is statistically identical to the source but shares zero one-to-one correspondence with original records. This distinction matters significantly for regulatory compliance: while anonymised data may still fall under GDPR or HIPAA scope if re-identification is possible, properly generated synthetic data typically does not. The utility preservation advantage is equally important. Anonymisation often destroys the correlations and statistical relationships needed for meaningful analysis. **Synthetic data maintains these patterns - mean, variance, multivariate dependencies - while eliminating privacy risks entirely.**

## How Synthetic Data Generation Works

The synthetic data generation workflow follows a consistent arc: analyse source data to extract patterns, build models that capture those patterns, and generate new data points that embody the learned characteristics without reproducing original records. The sophistication of each step determines the quality and utility of the resulting synthetic datasets.

### Statistical Distribution Modelling

Statistical approaches form the foundation of many synthetic data generation pipelines. The process begins with analysing the probability distributions present in the original data - identifying whether variables follow Gaussian, uniform, exponential, or custom distributions, and estimating their parameters.  
Copula models extend this by capturing multivariate dependencies between variables. Rather than assuming independence or simple correlations, copulas model the joint distribution structure, enabling the generation of data samples that honour complex relationships between columns in tabular data - critical when, for example, a synthetic financial transaction needs to respect correlations between amount, merchant category, and time of day. These methods excel when interpretability matters and when data relationships are well-understood. Implementation complexity varies: univariate distribution matching is straightforward, while accurately modelling high-dimensional dependencies requires careful statistical validation.

### Machine Learning-Based Generation

Machine learning models learn patterns from training data through supervised and unsupervised approaches. Neural networks, particularly deep learning models, capture non-linear relationships and complex feature interactions that statistical methods can miss. Supervised approaches train on labelled datasets to generate synthetic data with known properties. Unsupervised methods discover latent structure in unlabelled data, enabling the generation of realistic data that reflects inherent patterns without explicit specification. **The relationship between ML and statistical methods is complementary:** statistical techniques provide interpretable baselines and work well for structured formats, while ML approaches handle the complexity of unstructured data and high-dimensional feature spaces where explicit modelling becomes intractable.

### Simulation-Based Approaches

Monte Carlo methods generate data through repeated random sampling based on defined probability models. Agent-based modelling creates synthetic datasets by simulating individual actors following behavioural rules, producing emergent patterns that mirror real system dynamics. Physics-informed simulations and 3D environment rendering generate annotated datasets for autonomous systems, robotics, and computer vision. These approaches produce perfectly labelled training data for scenarios that would be dangerous, expensive, or impossible to capture from real environments. For blockchain applications, simulation-based approaches can model network behaviour, transaction propagation, and smart contract execution. DeFi protocol testing benefits from simulated market conditions, liquidation cascades, and multi-step transaction sequences that stress-test behaviour under extreme scenarios.  
These three technical foundations - statistical, ML-based, and simulation-driven - often combine in production systems, with the choice depending on data type, fidelity requirements, and computational constraints.

## Synthetic Data Generation Techniques and Implementation

Practical implementation requires selecting appropriate generative models and integrating them into development workflows. Here's what development teams need to know when moving from theory to production.

### Generative AI Models

**Generative Adversarial Networks (GANs)** pit two neural networks against each other: a generator that creates synthetic samples and a discriminator that learns to distinguish generated data from real data. This adversarial dynamic iteratively refines output until the synthetic data becomes statistically indistinguishable from the original. GANs are powerful but can suffer from training instability and mode collapse, where the generator learns to produce only a narrow range of outputs.  
**Variational Autoencoders (VAEs)** encode data into a compressed latent space and learn probabilistic mappings that enable sampling of new data points. VAEs offer more stable training than GANs and provide smooth interpolation between data samples, making them well-suited to applications where diversity and controllability matter.  
**Transformer-based models** - including large language models like GPT-4o - are increasingly applied to tabular and structured data generation by treating rows or records as sequences and learning dependencies across columns. These models excel at capturing long-range relationships and can be prompted with chain-of-thought reasoning to produce contextually accurate, culturally authentic outputs - a technique we used to great effect in the Panenka AI project (more on that below).

General implementation workflow:

1.  **Train the base model** on the original dataset with appropriate preprocessing and validation splits
2.  **Configure generation parameters** and constraints (privacy budgets, value ranges, referential integrity rules)
3.  **Generate synthetic samples** in batches, monitoring for mode collapse or distribution drift
4.  **Validate output quality** through statistical fidelity metrics and downstream task performance
5.  **Deploy the synthetic dataset** with appropriate documentation and lineage tracking

### Framework Comparison

| **Framework** | **Best For** | **Complexity** | **Notes** |
| --- | --- | --- | --- |
| TensorFlow / Keras | Custom GAN/VAE architectures, deep learning | High | Custom implementation required |
| Scikit-learn | Statistical methods, rapid prototyping | Medium | Standard tabular formats |
| Synthetic Data Vault (SDV) | Relational databases, tabular data | Low | Good for financial data structures |
| CTGAN | Mixed data types, complex distributions | Medium | Effective for transaction patterns |

Selecting the right tools depends on data complexity, team ML expertise, and pipeline integration requirements. For teams new to synthetic data, the Synthetic Data Vault offers accessible APIs. Teams with established ML infrastructure may prefer CTGAN or custom GAN implementations for greater control. For novel multi-modal requirements - like generating images, names, and behavioural patterns together - custom engineering is typically the only viable path.

## Real-World Example: Panenka AI - Gaming Synthetic Data at Scale

Panenka, an AI-powered football manager game, needed to generate 20,000+ unique player profiles - each with culturally diverse and realistic names from different countries, photorealistic faces with distinct features, and consistent ageing progression throughout a player's career, all without copyright violations or privacy concerns. 

This is exactly where off-the-shelf synthetic data platforms hit their limits:

*   Generic name generators produced repetitive, culturally inauthentic names and collided with famous footballers
*   Basic image generation tools produced inconsistent outputs with no ageing capability
*   Standard synthetic data platforms are built for structured tabular data, not multi-modal gaming assets

Our custom solution combined GPT-4o with Chain of Thought prompting and Self Consistency to generate culturally relevant names based on nationality - accounting for each country's diversity and cultural nuance while avoiding famous name combinations. For faces, we developed a 'genetic' approach: building detailed lists of facial element descriptors (lips, noses, eyebrows, cheekbones, freckles), then used GPT-4o to translate these into structured prompts that Leonardo.ai could process effectively. Player ageing was achieved by storing the original generation parameters (prompt, seed, and settings), ensuring appearance consistency as players progressed through their careers.  
**The result:** a fully scalable, privacy-safe synthetic data pipeline purpose-built for an entertainment product that no existing platform could have delivered. [Read the full case study here.](https://www.rumblefish.dev/case-studies/panenka/) 

## Common Challenges and Solutions

Implementing synthetic data generation in production environments surfaces practical obstacles that development teams must address systematically.

### Data Quality and Fidelity

Generated data quality depends on how well synthetic datasets preserve the statistical properties of real data while maintaining utility for downstream tasks. Implement validation using multiple metrics: Kolmogorov-Smirnov tests for distribution matching, correlation matrix comparisons for relationship preservation, and downstream task performance parity.  
High-quality data generation requires domain expert review alongside automated validation. A/B testing between synthetic and real data in non-critical applications can reveal subtle fidelity gaps that statistical tests alone may miss. Treat synthetic data quality as an ongoing process, not a one-time checkpoint.

### Scalability and Performance

Generating realistic synthetic data at enterprise scale, billions of records with complex interdependencies, strains computational resources. Optimise generation pipelines through distributed computing frameworks that parallelise independent generation tasks. Implement incremental generation strategies that produce data on demand rather than pre-generating massive datasets. Cloud infrastructure with auto-scaling (AWS is our stack of choice) enables burst capacity for load and performance testing scenarios that require high volumes.

### Regulatory Compliance and Privacy

While synthetic data eliminates direct privacy risks, regulators increasingly scrutinise generation processes. Establish differential privacy methods that provide mathematical guarantees on information leakage. Document generation methodology, training data sources, and validation results to demonstrate compliance.  
For GDPR, CCPA, and industry-specific regulations, maintain audit trails showing that no sensitive data persists in synthetic outputs. For high-stakes applications in healthcare or finance, consider third-party validation of your generation processes. Properly implemented synthetic data is one of the most robust privacy-preserving strategies available - but "properly implemented" is doing a lot of work in that sentence.

### Custom Engineering vs. Off-the-Shelf Platforms

This is a question we get often. Platforms like Gretel, MOSTLY AI, and Tonic are excellent for common use cases involving structured tabular data. They're quick to set up and require no ML expertise. But they have hard limits.  
When your requirements are complex, multi-modal, or domain-specific, **custom engineering pays for itself.** Here's how the two approaches compare:

|   | **Synthetic Data Platforms** | **Rumble Fish Custom Engineering** |
| --- | --- | --- |
| **Data scope** | Structured/tabular data primarily | Multi-modal: text, images, video, structured data |
| **Customization** | Configure pre-built generators | Engineer solutions for your exact requirements |
| **Industry fit** | Generic templates | Domain-specific intelligence built in |
| **Support model** | Self-service (you figure it out) | True partnership - we take full ownership |
| **Pricing** | Subscription per row/GB | Project-based - you own the solution |
| **Edge cases** | Works for common scenarios | Excels at complex, novel requirements |

The right choice depends on your requirements. If a platform fits your use case, use it. If it doesn't, that's where we come in.

## Conclusion and Next Steps

Synthetic data generation provides a privacy-preserving solution for modern development challenges, enabling teams to build and test AI systems without exposing sensitive production data. The technology bridges the gap between data utility requirements and regulatory compliance, while addressing fundamental problems of data scarcity and acquisition costs.

**Immediate actionable steps:**

*   Assess your current data constraints: identify where access restrictions or scarcity limit development velocity or model performance
*   Pilot with a bounded use case: start with test data generation for a single service to build organisational familiarity
*   Evaluate tools against your requirements: match your data types and technical needs against available frameworks and platforms
*   Consider whether your requirements fall outside what platforms can handle - if so, custom engineering is worth exploring

A comprehensive 2026 guide to synthetic data generation for development teams, covering technical approaches from GANs to transformers, with a detailed Panenka AI case study demonstrating custom multi-modal synthetic data engineering for gaming applications.

If you're building AI models, running software tests, or navigating the maze of data privacy compliance, you've probably run into the same wall: the data you need is either locked away, too expensive to collect, or legally off-limits. Synthetic data generation is how the smartest teams are breaking through that wall - and in this guide, we'll show you exactly how it works.

Synthetic Data Generation: A Complete Guide for 2026

The AI revolution is transforming how we build software. But there's a gap between the impressive capabilities of large language models and the practical expectations of business users who need familiar, reliable interfaces. At Rumble Fish, we've developed an architecture that bridges this gap - running Claude as a backend microservice that powers traditional-looking web applications with AI-driven intelligence.

## The Traditional Way: Claude as a Developer Tool

Most developers know Claude as either a built-in code assistant in popular IDEs like VS Code or Cursor, or as a standalone desktop application where you type prompts and get responses. These interfaces work great for technical users who are comfortable with conversational AI. But what about everyone else?

## The Challenge: AI for Non-Technical Users

At Rumble Fish, we've seen growing interest from clients who want to automate work that requires thinking and creativity - tasks that go beyond simple rule-based automation. Content analysis, document processing, research synthesis, and decision support - these are areas where AI excels.

**The challenge?** Most business users expect traditional browser-based interfaces. They're not comfortable typing prompts into a chat window and interpreting unstructured responses. They want buttons, forms, dashboards, and predictable workflows. How do we reconcile the creative, flexible nature of AI agents with the structured expectations of enterprise software?

## Our Solution: Claude as a Microservice

We run Claude as a containerized service on AWS. Here's how it works:

### The Container Setup

We package Claude using the Claude SDK inside a Docker container, deployed as an ECS task. Each container includes:

\- A checkout of a repository containing a \`CLAUDE.md\` file  
\- Skill definitions and scripts specific to the client's use case  
\- All the context the agent needs to perform its specialized tasks

The \`CLAUDE.md\` file acts as the agent's instruction manual - defining its role, output formats, and behavioral guidelines. This gives us precise control over how the agent operates while maintaining the flexibility that makes AI valuable.

### Persistence Through S3 Sync

At the start and end of each task, we run \`aws s3 sync\` to synchronize the agent's working directory with an S3 bucket. This simple mechanism provides:

\- **State persistence**: The agent accumulates knowledge between invocations  
\- **Audit trail**: Every file the agent creates is preserved  
\- **Easy integration**: Other services can read the agent's outputs directly from S3

## The Architecture in Detail

When a user interacts with our web interface, here's the sequence of events:

![Tables (1).png](https://strapi-uploads-staging-aldnr.rumblefish.dev/Tables_1_a1707dcb9d.png)

1.  **User Action:** The user clicks a button or submits a form in our React Admin interface
2.  **Backend Processing:** A Lambda function (exposed via API Gateway) receives the request and constructs a prompt for the agent
3.  **Queue Management:** The prompt goes into an SQS FIFO queue, ensuring ordered processing and preventing concurrent executions
4.  **Agent Execution:** An ECS task spins up, the agent processes the prompt, and generates its outputs
5.  **Result Storage:** Output files are synced back to S3, task metadata (ARNs, status) is stored in our database, and logs end up in another S3 bucket

### Why SQS FIFO?

The FIFO queue is crucial. While the agent is running, queue consumption is blocked. This prevents race conditions and ensures the agent always works with a consistent state. It also gives us natural backpressure - if requests come in faster than the agent can process them, they queue up gracefully.  

### Structured Output, Flexible Presentation

We instruct the agent (via \`CLAUDE.md\`) to save its analysis in markdown format at predictable locations. This gives us:

\- **No custom UI development:** Markdown renders beautifully with minimal effort  
\- **Flexibility:** The agent can structure its output however makes sense for the task  
\- **Readability**: Non-technical users can read and understand the results directly

The admin interface simply presents the contents of the S3 bucket. It doesn't need to understand what the agent does; it just displays what the agent produces.

## The Result: AI That Feels Like Software

The end product looks and feels like a standard web application. Users see familiar interfaces - lists, forms, buttons, dashboards. They don't need to learn prompt engineering or understand how AI works. But behind that familiar facade, Claude is doing work that would be impossible with traditional software: synthesizing information, making judgment calls, generating creative solutions, and adapting to edge cases that no developer anticipated.

It's the best of both worlds: the reliability and usability of traditional software, combined with the intelligence and adaptability of modern AI.

## Proven in Production

At Rumble Fish, we're currently running three different projects using this architecture. Each solves a different problem, but they share the same pattern:

*   Automate work that requires thinking, not just data shuffling
*   Present results through interfaces that traditional users understand
*   Maintain full auditability and control over the AI's behavior

This approach is becoming our go-to solution for a wide range of problems. The common thread: bridging intelligent automation with familiar user experiences.

## Is This Right for Your Organization?

If your team is exploring AI adoption but worried about user acceptance, complex integrations, or unpredictable behavior, **this architecture might be the answer.** It lets you harness AI capabilities while maintaining the control and predictability that enterprise environments demand.

Running Claude as a Backend Service: How We Build AI-Powered Web Applications on AWS

At Rumble Fish, a software development agency, we live in an industry defined by constant change. Adapt or become irrelevant - that's the reality we face every day. When AI coding assistants emerged, we were early adopters. But what surprised us wasn't Claude's ability to write code. It was everything else.

## The Work That Couldn't Be Automated

Every agency has tasks that seem immune to automation: analyzing datasets to find patterns, correlating information from multiple sources, or making sense of unstructured data. This work requires judgment, context, and the ability to handle exceptions. It's why we always assumed it needed humans.

**We were wrong.**

## A Different Kind of Intelligence

Claude doesn't just follow scripts. Its reasoning capabilities allow it to adapt when things don't go as expected. Feed it messy data, and it figures out what you meant. Throw it an edge case, and it works through it logically. You could almost call it creative - not in the artistic sense, but in the problem-solving sense.

We've built repositories that define skills Claude can use. These aren't rigid automation pipelines. They're flexible frameworks where Claude applies judgment within boundaries we set. **The results have been remarkable.**

## The New Division of Labor

The efficiency gain isn't about replacing humans. It's about changing what humans do.

**Before:** A team member spends hours on repetitive analysis, losing focus, getting tired, and making mistakes on the mundane cases while staying sharp for the interesting ones.

**Now:** Claude handles the repetitive work with unwavering consistency. It never gets bored. It maintains the same level of attention on case number 500 as it did on case number 1. And when it hits those edge cases requiring genuine creativity? It still delivers.

Humans review results, refine prompts, and handle the truly novel situations. It's a better use of everyone's capabilities.

## Claude in Practice

### Lead Generation

This use case was put together in just a few days by some of our engineers as part of their AI training. Historically, our marketing and sales team spent considerable time scouring the web for potential clients. It's such a time and labor-intensive task that it almost felt like a waste of effort.

**We built a Claude repository with skills that scrape publicly available job boards and identify relevant opportunities.** This goes far beyond what a traditional search query could do. We're looking for companies that offer remote work, are open to hiring an agency, and need expertise in technologies we specialize in: blockchain, ZKP, AWS, and AI. Claude turned out to be remarkably good at understanding job posts and rating them according to the rules we defined.

The result? We can now process a flood of information that was previously too massive to handle manually. This has opened an entirely new sales channel for our agency.

### Cloud Deployment for Team Collaboration

Most people encounter Claude as an IDE extension or a standalone desktop application. But there's another way: running the Claude SDK inside a Docker container.

This allows us to deploy Claude as an ECS task on AWS, which unlocks something powerful for team collaboration. **Multiple team members can share the same knowledge base and continuously update the skills and rules defined in the repository.** When someone refines a prompt or adds a new capability, everyone benefits immediately.

The result is a tool that effectively learns from the humans using it. Each improvement compounds, and the system gets smarter over time - not through model updates, but through collective human insight captured in the repository.

## Looking Forward

We believe this represents a fundamental shift in how knowledge work gets done. Not automation in the traditional sense, not rigid rules and brittle scripts. Something more flexible. Something that can think. **The agencies and teams that figure this out will operate at a different level of efficiency. The ones that don't will find themselves wondering how their competitors move so fast.**

We're still learning what's possible. But one thing is clear: Claude isn't just a coding tool. It's a thinking tool. And that changes everything.

Top ZKP Development Companies in 2026: A Guide to Zero-Knowledge Proof Experts

Oskar.jpg

Oskar Karcz

Welcome back! Seriously, welcome back, because we’re diving into the world of Zero-Knowledge Proofs (ZKP) once again. But this time, we’re looking at it from a fresh angle: the Stellar blockchain perspective.

I must admit, I was surprised by how beautifully this blockchain already supports ZKP - and their plans for the future are even more ambitious. So, if the clickbait title piqued your curiosity about what connects the God of the Sea (Poseidon) to medical imaging (X-ray), stay with me until the end. Grab a coffee, and let's explore elliptic curves, hash functions, and the magic of host functions.

## ZKP and Stellar: A Match Made in Heaven

I’ve already written a few articles about ZKP (like [ZKP Overview Part 2](https://www.rumblefish.dev/blog/post/the-current-state-of-knowledge-about-zero-knowledge-comprehensive-private-token-overview-part-2/) or [ZKP Overview Part 3](https://www.rumblefish.dev/blog/post/the-current-state-of-knowledge-about-zero-knowledge-comprehensive-private-token-overview-part-3/)), so before we dive in, please check those out to make sure you’re familiar with the basics. Or, you can ask your Agentic AI (oh look, [I wrote about that too!](https://www.rumblefish.dev/blog/post/agentic-ai/)) to explain keywords like circuits, Circom language, and proof generation/verification.

Let’s learn more about Stellar. They introduce themselves as  _“an open-source blockchain used for a variety of payment and remittance applications.”_ It’s a wide net, but the most interesting Stellar feature for us right now is how it supports ZKP, and how we can write smart contracts that utilize this facet. The Stellar network has a smart contract platform called Soroban. Smart contracts here are written in Rust and compiled to WebAssembly (Wasm) for deployment ([source](https://developers.stellar.org/docs/build/smart-contracts/overview)). That’s enough for us to know at the moment, but if you’re interested in getting your hands dirty with Soroban, check out the [Getting started guide](https://developers.stellar.org/docs/build/smart-contracts/getting-started).

Not so long ago, in 2024, Stellar took a quantum leap toward adopting advanced ZKP systems by [adding support for the **BLS12-381 elliptic curve**](https://github.com/stellar/rs-soroban-env/issues/779). But what exactly do I mean by “adding support”? To understand this, let’s take a quick detour into the world of host functions.

## Host Functions: The Captain and the Nav-Computer

Let’s use a space-themed analogy (we are talking about Stellar, after all). Imagine your smart contract is the Captain of a starship. If the Captain needs to open a sliding door or turn on the lights (simple smart contract logic), they do it easily. It consumes almost no energy. But imagine the Captain needs to calculate a hyper-jump trajectory through a moving asteroid field (that’s the heavy ZKP math). If the Captain tried to calculate this by hand using a pencil and paper on the bridge, it would take weeks, burn through all the ship's life support reserves (gas fees), and the ship would likely crash before the answer was found.

A host function is like using the ship’s dedicated Nav-Computer. The Captain doesn't do the math manually; they just punch in the destination and hit "Calculate." The ship’s mainframe (the Stellar nodes) runs the complex physics equations instantly using highly optimized hardware circuits. The Captain still decides where to go (the logic), but the heavy lifting is offloaded to the machine built specifically for speed. In technical terms, the "Nav-Computer" is the pre-compiled, native machine code running on the node, which is infinitely faster than the "Captain" trying to run math inside the constrained Wasm environment. Generally speaking, every blockchain has its own unique set of host functions (often called "precompiles," "syscalls," or "native programs"). Think of them like the operating system APIs for that specific blockchain.

### BLS12-381…

So, back to the main topic: "adding support" meant adding host functions for BLS12-381 and its underlying field arithmetics. In simple terms: "Now you can play around with ZKP on Stellar!" Wooooow, isn’t that awesome? But if you opened the GitHub issue link I shared earlier ([this one,](https://github.com/stellar/rs-soroban-env/issues/779) cheers if you did!), you might have read: “The most widely used pairing friendly curve is BN254 (...) due to the fact that Ethereum has support for it.” Wait. What is BN254? Why was BLS12-381 chosen first? AND WHY DO THESE NAMES LOOK SO RANDOM? Let’s take another detour to talk about elliptic curves.

### … and BN254

At their core, elliptic curves are specific mathematical structures, essentially complex algebra equations graphed as curves, that allow computers to perform cryptographic tasks like signing transactions or verifying proofs extremely efficiently. The names BN254 and BLS12-381 might look random, but they are scientific labels: "BN" and "BLS" stand for the researchers who discovered the curve families (Barreto-Naehrig and Barreto-Lynn-Scott), while the numbers describe precise parameters like the size of the prime numbers used to build them.

Think of these two curves as incompatible types of mathematical railroad tracks designed for the heavy lifting of Zero-Knowledge proofs.

*   **BN254** (aka \`alt\_bn128\`) acts like a "legacy" high-speed rail line from around 2015. It was adopted early by Ethereum, making it the standard track for thousands of existing applications because it is lightweight and cheap to run. However, later research found its security walls (about 100-bit) to be slightly thinner than originally intended.
*   **BLS12-381** is the modern, heavy-duty freight line designed for long-term safety. It offers the gold-standard 128-bit security preferred by newer networks like Zcash and Ethereum 2.0. This extra armor means its keys are larger and its operations require slightly more computational power.

Because a proof written for one curve is mathematically unreadable by the other, Stellar's decision to support both is like building a station that can service both the older, widespread commuter trains and the newer, heavy-armored security transports. This ensures developers don't have to rebuild their entire fleet just to switch networks.

## X-RAY: The Protocol Upgrade That Changes Everything

So, did Stellar make the right decision by implementing BLS12-381 first and not BN254? Yes and no. Yes, for the security reasons I mentioned above. No, because right now (Jan 2026), implementing support for BN254 is… actively in progress! But why? As explained in [_CAP-0074: Host functions for BN254_](https://github.com/stellar/stellar-protocol/blob/master/core/cap-0074.md) (CAP stands for Core Advancement Proposals): _“While Stellar has native support for BLS12-381, many existing applications still rely on BN254 because it's the only pairing-friendly elliptic curve with native support in the EVM. Adding BN254 support will allow those applications to add support for Soroban without the need to use a different curve.”_

Without native Soroban support for BN-254, developers building ZK apps on Stellar would have to either rewrite their applications or maintain complex workarounds. Supporting both gives developers the flexibility to choose the curve that best suits their goals. In Nov 2025, the Stellar Team announced an upcoming protocol upgrade called X-Ray. This upgrade proposes native support not only for BN254 but also for another important ZK primitive: Poseidon!

## Poseidon: The Hash Function Built for Zero-Knowledge

Poseidon is a family of hash functions designed specifically for ZKP systems. As the article states: _“While BN254 provides the pairing operations for proof verification, you also need an efficient cryptographic hash, which is where Poseidon comes in. (...) These primitives let developers design hash functions that are highly efficient in ZK circuits, addressing a key performance bottleneck in ZK systems.”_

Traditional hashes like SHA-256 are computationally expensive to model within proofs. Poseidon is like a sports car built specifically for the ZK racetrack. And again, adding support for it means adding a host function to Soroban. This was introduced in [CAP-0075: Cryptographic Primitives for Poseidon/Poseidon2 Hash Functions.](https://github.com/stellar/stellar-protocol/blob/master/core/cap-0075.md)

## Why This Matters?

This perfect duo, **CAP-0074** and **CAP-0075,** establishes the rock-solid cryptographic foundation developers have been waiting for. It allows us to build privacy-preserving applications on Stellar without compromising the transparency that makes blockchain so powerful.

So, what does this actually unlock for us? (Glad you asked!):

*   **Smooth Sailing:** Migrating existing ZK apps becomes a walk in the park.
*   **Turbo Efficiency:** Proof systems become faster, leaner, and more powerful.
*   **Wallet-Friendly:** We’re talking significantly lower costs for ZK-based contracts.
*   **The Big Bridge:** It opens a massive gateway to the broader ZK ecosystem, inviting everyone to the party.

I hope this (zero-) knowledge unlocks your curiosity and willingness to give Stellar a try with your new ZKP project. I’ve already tried it and can’t wait to see both CAPs live on mainnet! In the meantime, stay tuned, and as always, [reach out to us if you have any questions.](mailto:hello@rumblefish.dev) See you next time!

An exploration of Stellar's zero-knowledge proof capabilities, explaining how the X-Ray protocol upgrade adds support for BN254 elliptic curves and Poseidon hash functions to enhance ZKP development on the Stellar blockchain.

This article explores how the Stellar blockchain supports Zero-Knowledge Proofs through its Soroban smart contract platform, focusing on the implementation of two elliptic curves: BLS12-381 (already supported for high security) and BN254 (coming soon for Ethereum compatibility). The upcoming X-Ray protocol upgrade will add native support for BN254 and Poseidon hash functions, which are specifically optimized for ZKP systems and significantly more efficient than traditional hash functions like SHA-256. Together, these additions will make Stellar a powerful platform for privacy-preserving applications by lowering costs, improving performance, and enabling seamless migration of existing ZK applications from other blockchains.

What Connects Poseidon to X-Ray: A Deep Dive into ZKP on Stellar

Lately, we've been discovering all the different flavors of blockchain technology - from the nitty-gritty of XRP Hooks to the complex machinery of Solana's indexers. But this time, let’s switch gears a little bit to explore another amazing and rapidly growing universe: AI. We’ve moved from simply chatting with AI to watching it write code, debug errors, and even browse the web. But are we really maximizing this potential? Is typing into a prompt box really the peak of evolution? I don't think so! Today, we’re going to step into the next frontier: Agentic AI. If you’ve ever felt like your favorite chatbot is brilliant but lazy, waiting for you to do all the copy-pasting, this article is for you. So, grab a massive cup of coffee, find a comfy spot to read, and let’s dive into the world of autonomous agents!

## The Name’s AI. Agentic AI.

Let’s be honest. "Agentic AI" sounds a bit like a buzzword salad, doesn't it? But stick with me. To understand what this actually is, we need to leave the boring server room and head to the movies. Think of a standard LLM (like GPT-4 or Claude) as “M” from the James Bond movies. M is incredibly smart, has access to all the intelligence files, and sits safely in an office in London. M can tell you what to do, analyze the situation, and give you a strategy. But M doesn’t leave the desk. M can’t drive the Aston Martin, and M certainly can’t defuse the bomb.

In the tech world, Agentic AI is an artificial intelligence system that acts just like 007. It has the same intelligence as M (the LLM brain), but it also has a License to Kill (Tasks). It’s not just generating text; it’s taking action in the real world (or at least, the digital world). It has permission to use "gadgets" (tools), make decisions on the fly, and execute missions without phoning home for every single step.

### The 00-Section: A Team of Agents

OK, so Agentic AI is an artificial intelligence system that can accomplish a specific goal with limited supervision. But you know what the cool thing is? Agentic AI isn't just a lone wolf running wild. Often, it’s not just one Bond, but a whole squad of 00-specialists. In a multi-agent system, you have individual agents - machine learning models that mimic human decision-making - where each one performs a specific subtask required to reach the goal. Think of it like a heist movie: one agent is the driver, another is the hacker, and another is the safe-cracker. Their efforts are coordinated through **AI orchestration** to solve problems in real-time.

## GenAI vs. Agentic AI: The Lab vs. The Field

_"But wait a sec,"_ I can hear you asking, _"isn't this just ChatGPT with a fancy new marketing name?"_ Excellent question! But the answer is a resounding no. Let’s distinguish the two. Think of traditional Generative AI (GenAI) as Q’s laboratory. It’s fantastic at creating things based on learned patterns. It can manufacture a gadget, write a dossier, or generate a code snippet. It focuses on outputting content. Agentic AI, on the other hand, is the agent taking that gear into the field to do stuff. It extends the capability of GenAI by applying those outputs toward specific goals.

*   **GenAI:** Can tell you the best time to climb Mt. Everest based on your work schedule.
*   **Agentic AI:** Will look at your schedule, access a travel API, book your flight to Nepal, reserve a hotel room, and maybe even order you a pair of thermal socks.

See the difference? **One chats, the other acts.** Unlike traditional models that operate within predefined constraints and wait for you to click "enter," Agentic AI exhibits goal-driven behavior. It looks at the objective, figures out the steps, and executes them by calling external tools. So, why is this the new hotness? Because we are moving from the era of "Chatbots" to the era of "Actionbots".

*   **Autonomy:** They don't need you to babysit them.
*   **Adaptability:** If the flight to Nepal is cancelled, a good agentic system figures out an alternative route rather than just throwing an error message.
*   **Orchestration:** You can chain complex workflows together that used to require a human project manager.

It’s about to get very interesting for developers who want to build systems that don't just think but actually work.

## The Double-Edged Sword

Unfortunately, real life isn’t quite like the movies. We aren't yet in that luxurious position where we can just sit back, relax, and watch our agents handle everything for us. Giving an AI a "License to Act" comes with risks. If 007 goes rogue, buildings explode. If your Agentic AI gets stuck in an infinite loop while using a paid API... well, your credit card bill explodes. Threats?

*   _**Infinite Loops:**_ The agent keeps trying to solve a problem it can't solve, burning tokens like there's no tomorrow.
*   _**Hallucinations in Logic:**_ The agent _thinks_ it saved the file, but it actually just wrote a print statement saying it did.

This is why "Human-in-the-loop" is still a massive concept in this space. Sometimes, even Bond needs to call M for authorization before launching the missile.

## Mission Debrief

That’s it! We’ve taken a journey from the passive desk-job LLMs to the action-packed world of Agentic AI. We’ve seen how giving models "gadgets" and a "reasoning loop" turns them into autonomous operators capable of complex workflows. The technology is still young, and the frameworks (like LangChain or CrewAI) are evolving faster than a car chase scene. But the potential? Limitless.

If you are curious about how to implement these agents in your own stack, or how to orchestrate a fleet of them to handle complex logic (maybe even on-chain?), keep your eyes peeled for our next updates. As always, feel free to jump into our repositories or [reach out to the team](mailto:hello@rumblefish.dev) if you have any questions. Until next time, keep your code clean and your agents licensed!

A guide to agentic AI systems that can autonomously perform tasks, make decisions, and interact with tools to achieve complex goals beyond simple question-answering.

Lately, we've been discovering all the different flavors of blockchain technology - from the nitty-gritty of XRP Hooks to the complex machinery of Solana's indexers. But this time, let’s switch gears a little bit to explore another amazing and rapidly growing universe: AI. We’ve moved from simply chatting with AI to watching it write code, debug errors, and even browse the web. But are we really maximizing this potential? Is typing into a prompt box really the peak of evolution? I don't think so! Today, we’re going to step into the next frontier: Agentic AI.

Agentic AI: Your Code’s License to Kill (Tasks)

I guess we all know someone who never remembers anniversaries, birthdays, or any important dates. I have to honestly admit that I am that person, which is why I rely on calendars and notes apps to keep everything organized, set reminders, and quickly find whatever information I need.   
Now, let’s put that simple solution to my issue into a blockchain context. A blockchain is a public, distributed ledger in which data is linked together using cryptographic hashes. You might imagine it as one giant list of dates and records, like storing your whole family’s birthdays in one place. The problem is, it doesn’t give you a straightforward way to ask, e.g., for only the birthdays happening this month.  
That’s the fundamental misunderstanding people have about blockchains.

## The Misconception: “Blockchain = Queryable Database”

Imagine you’re running a company and want to give birthday bonuses to employees who’ve been with you for over 5 years, but only if their birthday falls this month. On a blockchain, it’s easy to prove something basic, like:  
_“I employ Alice, Bob, and John.”_  
But asking a more practical question is a whole different story:  
_“Show me all employees with over 5 years of tenure whose birthdays are this month.”_  
And here’s the catch: many people assume blockchains behave like normal searchable databases. They don’t. A blockchain is an append-only log, fantastic for storing and verifying transactions, terrible for querying them. Nodes return raw bytes and unindexed logs. Even simple questions may require scanning through thousands of transactions manually.  
**That’s why we need indexers.**  
Indexers turn low-level, unstructured data into clean, queryable information so applications can answer questions in milliseconds instead of minutes.

## Indexers

Every blockchain works differently, so there’s no universal, magical solution for indexing data. Even within a single ecosystem, like Solana, multiple approaches exist, each with unique trade-offs.  
So let's stay here for a moment and take Solana as an example and a case study. Why? Because Solana processes thousands of transactions per second (TPS) (btw if you’re interested in how many exactly, [take a look here](https://chainspect.app/chain/solana)), and each one hides meaning inside opaque instruction bytes that every program decodes differently: SPL Token, Metaplex, various DEXes, custom programs, you name it.  
What you want to extract also varies depending on your use case:

*   real-time alerts
*   deep historical analytics
*   simple token tracking

Each of these demands a different strategy. This is why we don’t have a single "one tool to rule them all." There’s a natural trade-off triangle between:

*   speed to market
*   depth of customization
*   operational complexity

No tool maximizes all three, so the ecosystem evolved into a toolbox of specialized indexers tailored for different jobs. 

### Indexers Overview

Below is a synthesized comparison of the most widely used Solana indexing solutions.

| Solution | Type | Best For | Complexity | Cost Model | Latency | Solana Maturity |
| --- | --- | --- | --- | --- | --- | --- |
| Helius | Managed API | Fast MVPs, common use cases | **⭐** Low | Usage-based | Low (200-500ms) | **⭐⭐⭐⭐⭐** Excellent |
| Subsquid | Hybrid framework | Custom programs, analytics | **⭐⭐** Medium | Infra + compute | Medium (1-3s) | **⭐⭐⭐** Good |
| Substreams | Parallel ETL | High-throughput backfill | **⭐⭐⭐** High | Infra + Firehose | Low/Medium (1-2s) | **⭐⭐** Emerging |
| Geyser Plugin | Custom streaming | Ultra-low latency, full control | **⭐⭐⭐⭐⭐** Very high | Node + infra | Very low (\<100ms) | **⭐⭐⭐⭐** Mature |

#### Quick Overview of Each

**Managed APIs (Helius)**  
Plug-and-play indexing for tokens, NFTs, and wallets - with zero DevOps. Perfect for teams that need to ship fast. The trade-off: limited customization and vendor lock-in.  
**Hybrid Frameworks (Subsquid)**  
A middle-ground solution. You write custom decoding logic in TypeScript, backed by decentralized archives and GraphQL APIs. Great for analytics without heavy infra work.  
**Parallel ETL Pipelines (Substreams)**  
The high-horsepower option. Rust WASM modules process historical data in parallel, enabling massive backfills at extreme speed. Requires Rust skill and Firehose infra.  
**Custom Streaming (Geyser Plugins)**  
Ultra-low latency, full control. You tap directly into a validator to stream account updates in under 100ms. Ideal for stuff like HFT or compliance systems, but you must run full nodes and streaming infra like Kafka.

## Case Study: Substreams

Imagine trying to understand everything happening on Solana. It’s like standing in front of a conveyor belt that never stops - boxes flying past, most of them are irrelevant, and you’re looking for just the one. The beauty of Substreams is that it transforms this chaos into clean, structured data using sinks. As [the docs say,](https://docs.substreams.dev/how-to-guides/sinks) _Sinks are integrations that allow you to send the extracted data to different destinations, such as a SQL database or a file._   
Let’s say you want your results in a JSON file. Here’s how Substreams turns a torrent of data into a tidy output.json.

![4.jpg](https://strapi-uploads-staging-aldnr.rumblefish.dev/4_ada265ac69.jpg)

### Substreams: A Step-by-Step Walkthrough

**1\. Solana Blockchain - The Raw Stream**  
Every ~400ms, Solana produces a block filled with everything: votes, transfers, swaps, and random program calls. No order, no filtering.

**2\. Firehose - Capture Everything First**  
Firehose nodes collect all chain data; it’s like downloading the entire chat history, not just unread messages.

**3\. Substreams Loads Your Config**  
Your substreams.yaml (the Substreams manifest) tells the engine exactly which modules to run and how data should flow. For example, by enabling _solana:blocks\_without\_votes,_ you instantly strip away a massive amount of “background noise” before your code even sees the data.  
In simple terms, the manifest is a YAML configuration file that defines your Substreams pipeline: what goes in, which modules process it, and what comes out. It can, for instance, take a raw blockchain block (like _sf.ethereum.type.v2.Block_) and transform it into a clean, custom output type (such as _eth.example.MyBlock_).

Code example:

```plaintext
modules:
 - name: map_block
   kind: map
   initialBlock: 12287507
   inputs:
     - source: sf.ethereum.type.v2.Block
   output:
     type: proto:eth.example.MyBlock
```

**4\. Infrastructure Filter**  
This built-in module strips out vote transactions before your code runs.  
100 total transactions  
↓ remove vote txs  
≈ 20 remain

**5\. Write Your Custom Logic**  
Now you apply your rules:

*   Does this involve the MOFT token?
*   Is the Token Program used?
*   Does the instruction match what you need?

Your custom rules are written as a Substream module in a Rust function that receives an input and returns an output. For example, the following Rust function receives an Ethereum block and returns a custom object containing fields such as block number, hash, or parent hash.

```plaintext
fn get_my_block(blk: Block) -> Result<MyBlock, substreams::errors::Error> {
   let header = blk.header.as_ref().unwrap();
   Ok(MyBlock {
       number: blk.number,
       hash: Hex::encode(&blk.hash),
       parent_hash: Hex::encode(&header.parent_hash),
   })
}
```

**6\. Your WASM Module**  
Your custom logic is set in the Substreams Manifest as the path to the .wasm file built from the Rust function. E.g.  _map\_my\_data_ function receives only the filtered transactions, not the full firehose.  
20 filtered transactions  
↓ apply rules  
1 match

**7\. Substreams Converts Output to JSON**  
Your protobuf schema is automatically serialized into JSON.

**8\. Final Output**  
You get a clean, ready-to-use output.json.

![Tables.jpg](https://strapi-uploads-staging-aldnr.rumblefish.dev/Tables_fb4421c78e.jpg)

**Recap:**  
→ Raw block (100 txs)  
→ Firehose captures everything  
→ Substreams loads config  
→ Vote txs removed → **20 left**  
→ Your logic → **1 match**  
→ Convert to JSON  
→ Save to _output.json_

### **Key Takeaways**

Substreams works because it uses two layers of filtering:

*   The system removes broad noise
*   Your code extracts the precise data you need

It turns chain data from a warehouse search into opening a mailbox with only the letters you care about.

## Case Study: Helius

Helius provides the APIs and infrastructure needed to build production-ready Solana applications. Their data streaming system lets applications receive real-time on-chain updates without polling.  
As [the docs put it](https://www.helius.dev/docs/data-streaming#what-is-data-streaming-on-solana), _Data streaming allows applications to receive real-time updates from the Solana blockchain as events occur on-chain. Instead of repeatedly polling for updates, streaming establishes persistent connections that push data to your application instantly when transactions are processed, accounts change, or blocks are produced._  
Now, let’s examine how Helius enables indexing through a clean, predictable pipeline.

### How the Helius Indexer Pipeline Works

The pipeline has two lanes, historical and real-time, but both pass through the same parser before landing in PostgreSQL.

![5.jpg](https://strapi-uploads-staging-aldnr.rumblefish.dev/5_1472efb076.jpg)

### Helius: A Step-by-Step Walkthrough

**1\. Solana Blockchain → Helius API**  
Solana emits raw transactions - SOL transfers, SPL token activity, CPI-heavy program calls.  
Helius exposes this data through:

*   **Batch endpoints** (for historical backfills)
*   **Webhooks** (for real-time updates)

This gives you structured data without running a validator.

**2\. Backfill Worker (Historical Processing)**  
Your archive crawler:

*   Fetches signatures (100 at a time)
*   Retrieves full transactions in batches of 25
*   Parses all instructions and CPIs
*   Extracts SOL transfers, token transfers, mints, and burns
*   Writes everything to PostgreSQL
*   Tracks progress to resume safely

**Purpose:** rebuild the full historical data you need.

**3\. Webhook Worker (Real-Time Updates)**  
Handles the live stream:

*   Receives new transactions within ~2–3 seconds
*   Uses the same parsing logic as the backfill
*   Writes new data into the same tables

**Purpose:** keep your database continuously synced with the chain.

**4\. Unified Transaction Parser**  
Both workers rely on one parsing module that:

*   Identifies program IDs
*   Handles System Program, Token Program, and your custom programs
*   Decodes CPIs
*   Normalizes results into structured records

**Purpose:** convert chaotic transaction logs into clean SQL rows.

**5\. PostgreSQL Storage**  
Data is stored across three important tables:

*   transfers → all token & SOL movements  
*   program\_events  → custom program interactions  
*   ingestion\_state → backfill checkpoint tracking

**Purpose:** provide a stable, analytics-ready schema.

### Key Takeaways

*   **Two lanes of ingestion** → backfill (past) + webhooks (present)
*   **One unified parser** → consistent data across time
*   **CPI-aware logic** → captures what programs actually do
*   **Resumable backfill** → no missing or duplicated data
*   **SQL-first design** → fast queries, dashboards, and analytics

This architecture gives you an end-to-end indexing pipeline, from raw on-chain activity to fully structured records, without maintaining your own validator.

## Indexers on Solana: A Summary

I hope it’s clear now that working with blockchain data isn’t as straightforward as it seems at first glance. We walked through two popular indexing approaches, Substreams and Helius, each optimized for different needs. This is not the only way to handle blockchain data, of course. My goal here was simply to show what’s possible, highlight the trade-offs, and encourage you to explore further.  
As always: do your own research, experiment, and choose the right tool for your use case. And don’t forget to index the results of your digging, so you can actually use them quickly and without pain. No need to thank me. Cheers!

Indexers on Solana: Why Blockchain Data Isn’t as Simple as It Seems

In the rapidly evolving landscape of music technology, blockchain is emerging as a powerful catalyst for transforming how intellectual property rights are managed and distributed. The global blockchain-enabled music licensing market reached $320 million in 2024 and is projected to grow at a robust 28.5% CAGR, reaching $2.93 billion by 2033 [(Growth Market Reports)]($https://growthmarketreports.com/report/blockchain-enabled-music-licensing-market$). Yet, despite this momentum, the industry faces a fundamental challenge: how do you bring complex, decades-old metadata standards like DDEX onto a blockchain in a way that's both secure and scalable?  
When Original Works, a foundation incubated by Revelator, a leader in music rights management, approached us with this exact challenge, we knew we were stepping into uncharted territory. The result? A decentralized DDEX registry powered by Zero-Knowledge Proofs that cut proof generation time from 16 hours to just 3 minutes, setting a new standard for what's possible at the intersection of blockchain and music metadata.

## The Music Industry's $2.5 Billion Problem

Picture this: an estimated $2.5 billion in royalty payments that should be paid to artists are currently delayed or unpaid [(Gamma Law)](https://gammalaw.com/how-blockchain-will-change-the-music-industry/). The culprit? An outdated, fragmented system for managing music intellectual property rights that hasn't fundamentally changed in decades. While streaming services like Spotify and Apple Music have revolutionized music consumption, the backend infrastructure for tracking ownership, licenses, and royalties has struggled to keep pace.  
The industry standard for exchanging music metadata is DDEX (Digital Data Exchange), an XML-based format that enables companies to communicate information along the digital supply chain. DDEX is widely adopted by major players, including streaming platforms, record labels, and digital distributors. Yet for all its ubiquity, DDEX comes with significant limitations: it's centralized, prone to data silos, and lacks the transparency and immutability that blockchain technology promises. The global streaming sector alone hit $46.66 billion in 2024 [(The Music Universe)](https://themusicuniverse.com/the-blockchain-beat-why-the-music-industry-is-listening-closely/), yet the infrastructure managing rights and royalties behind these streams remains fundamentally outdated.

## The Challenge: Validating 50,000 Lines of XML Rules On-Chain

Original Works set out to create a decentralized ecosystem for IP management that would provide a unified, tamper-proof, and automated system for sharing and validating critical information between industry stakeholders. The vision was clear: transition DDEX registration to the blockchain. The execution? That's where things got complex.

### What Made This Project Unprecedented

DDEX messages use XML format and follow strict schemas (XSD) with over 50,000 lines of validation rules. Imagine trying to verify that a music release conforms to tens of thousands of business rules, everything from proper artist credits to territorial licensing restrictions, without relying on a centralized authority. That's exactly what we needed to achieve.  
The technical hurdles were formidable:

*   **Complex Schema Validation:** Validating XML against XSD schemas requires sophisticated parsing logic, far too complex for traditional smart contracts.
*   **Gas Cost Constraints:** Conducting XML validation directly on Ethereum would be prohibitively expensive due to transaction gas limits. We needed a way to prove validation happened correctly without executing it on-chain.
*   **Scalability Demands:** The music industry processes thousands of releases daily. Our solution had to scale to handle real-world transaction volumes efficiently.
*   **Data Availability:** Ethereum's new EIP-4844 BLOBs allow storing large data on-chain, but only for 18 days. We needed a mechanism to ensure long-term accessibility and auditability.

[![Tables (3).png](https://strapi-uploads.rumblefish.dev/Tables_3_01f95a14c7.png)](https://www.rumblefish.dev/case-studies/decentralized-ddex-registry-original-works/)

## The Solution: Zero-Knowledge Proofs Meet Music Metadata

At the core of our approach was Risc0, a Zero-Knowledge Virtual Machine that enables generating cryptographic proofs for complex computations. Think of Zero-Knowledge Proofs as a way to prove you've done your homework correctly without showing your work - you can verify that XML validation happened according to DDEX rules without actually executing that validation on the blockchain.

### How We Built It: The Technical Architecture

Here's where things get interesting. By leveraging Risc0, we could write validation logic in Rust, a language with mature libraries for XML parsing, while ensuring the computational process remained verifiable and tamper-proof. This was crucial because DDEX messages often contain embedded files like album cover images that need to be extracted and stored separately.  
Our CLI tool first extracts these embedded files and uploads them to IPFS (the InterPlanetary File System), replacing local file paths with corresponding Content Identifiers (CIDs). This ensures all media assets are preserved in a decentralized manner before the message is packed into an EIP-4844 BLOB and submitted on-chain.  
Once validators retrieve a BLOB, they process it using Risc0, extracting key metadata while generating a Zero-Knowledge Proof that verifies the correctness of the operation. Since BLOBs disappear after 18 days, we implemented an archival mechanism where validators upload both the raw BLOB and its extracted, human-readable JSON-formatted messages to IPFS. The CID of the archived BLOB is then recorded in our subgraph, ensuring long-term availability and complete auditability.

## The Breakthrough: From 16 Hours to 3 Minutes

Initially, generating Zero-Knowledge Proofs for XML validation took up to 16 hours per file, far from practical given the high volume of daily transactions in the music industry. This was our most critical bottleneck. To optimize proof generation, we took several strategic steps. First, we preprocessed raw XML files into JSON, reducing computational complexity while maintaining data integrity. This alone yielded significant improvements. Then came the game-changer: GPU acceleration and hardware-specific optimizations.  
**The result? We cut proof generation time from 16 hours to just 3 minutes,** a 320x improvement that made real-world deployment not just feasible, but practical. The resulting proofs, along with extracted metadata, are submitted to our smart contracts, where they're verified and emitted as on-chain events. Our subgraph indexes these events, completing the decentralized pipeline for registering and validating intellectual property metadata.

## Real-World Impact: What This Means for the Music Industry

Beyond the impressive performance metrics, this project addresses fundamental pain points that have plagued the music industry for years. By bringing DDEX metadata onto the blockchain with Zero-Knowledge Proof validation, we've created a system that is:

*   **Transparent:** All metadata registrations are recorded on-chain, providing an immutable audit trail that anyone can verify.
*   **Tamper-Proof:** Once metadata is registered and validated, it cannot be altered retroactively, protecting artists and rights holders from disputes.
*   **Scalable:** With 3-minute proof generation times, the system can handle the thousands of releases that flow through the industry daily.
*   **Decentralized:** No single entity controls the validation process—a network of validators ensures data integrity through cryptographic proofs.

Consider the implications: artists who currently wait months to see royalty payments could potentially receive compensation in near real-time. Record labels and publishers gain unprecedented visibility into how their catalog is being used across different platforms and territories. Digital Service Providers can access standardized, verified metadata that reduces licensing friction and accelerates content distribution.

## The Broader Context: Blockchain's Role in Music's Future

This project sits at the intersection of several converging trends in the music and blockchain industries. While blockchain adoption in music is still in its experimental phase, [with most initiatives being proofs of concept or pilots,](https://www.sciencedirect.com/science/article/pii/S0308596124001149) the technology's potential to transform rights management is undeniable. According to recent research, the main impediments to mass blockchain adoption in music aren't technological; they're about data governance, standardization, and the limited quality of existing music metadata. By tackling DDEX integration head-on, we're addressing these fundamental challenges rather than building isolated blockchain solutions that can't interoperate with existing industry infrastructure.  
As Bruno Guez, CEO of Revelator, noted [in an interview](https://www.thestreet.com/crypto/innovation/how-blockchain-is-reshaping-music-industry-payments): 

> _"We're using a token incentive design to boost fan engagement, transforming the way artists interact with their audiences. The music industry isn't ready for Web3 yet, but for that to change, every music company needs to be able to support a new blockchain-based infrastructure across the digital supply chain."_ 

This includes everything from tokenization and smart contracts to automated payments.

## Technical Innovation: Why Zero-Knowledge Proofs Matter

Zero-Knowledge Proofs represent one of the most powerful cryptographic innovations for blockchain scalability and privacy. In 2024, we've seen rapid advances in ZKP technology, from [hardware acceleration achieving 586x speedups](https://people.csail.mit.edu/devadas/pubs/micro24_nocap.pdf), to new proof systems that handle neural networks and complex computations efficiently.  
For the music industry specifically, ZKPs solve a critical problem: how do you prove complex business logic compliance (like DDEX validation) without revealing sensitive commercial information or incurring prohibitive on-chain execution costs? Our implementation demonstrates that ZKPs aren't just theoretical - they're production-ready for real-world data validation at scale.

## Lessons Learned: The Challenges We Overcame

That said, bringing DDEX to blockchain came with its unique set of challenges that demanded creative problem-solving. The integration of cutting-edge technologies like EIP-4844 BLOBs for data availability and the Risc0 virtual machine for generating Zero-Knowledge Proofs added layers of complexity. These technologies, though groundbreaking, came with limitations that required rigorous optimization. The ultimate challenge was balancing the computational demands of Zero-Knowledge Proofs with real-world scalability. Initial proof generation times of 16 hours simply weren't viable; we had to push the boundaries of what was possible with hardware optimization, careful algorithmic choices, and preprocessing strategies.  
Our team of blockchain developers worked intensively over four months, iterating on architectures and testing different optimization approaches. The breakthrough came from a combination of preprocessing XML to JSON, implementing GPU acceleration, and fine-tuning the proof generation pipeline. Each improvement built on the last, ultimately achieving the dramatic performance gains we needed.

## What's Next: The Future of Decentralized Music IP

The Original Works project demonstrates that blockchain technology can handle the complexity of real-world music industry workflows, not as a distant future possibility, but today. With proof generation optimized to 3 minutes and a fully decentralized validation network, the system is ready to process the high volume of metadata exchanges that the industry demands.  
Looking ahead, we anticipate more music companies adopting blockchain-based infrastructure as the technology matures. The transparency, security, and efficiency gains are too significant to ignore. As Gilad Woltsovitch, Co-Founder of Original Works, put it: 

> _"The innovative solutions developed by the Rumble Fish team were instrumental in overcoming the complex challenges of bringing DDEX metadata to the blockchain. The result is a decentralized, efficient, and scalable system that has fundamentally transformed how we manage intellectual property metadata."_

  
For artists, this means faster royalty payments and greater control over their intellectual property. For publishers and labels, it means reduced administrative overhead and improved rights tracking. For the entire industry, it means a more transparent, equitable ecosystem where creators are fairly compensated, and stakeholders can trust the data they're working with.

## Conclusion: Building the Infrastructure for Music's Blockchain Future

Through this collaboration with Original Works, we've successfully built an efficient, scalable, and fully decentralized system that brings DDEX metadata management onto the blockchain. The technical innovations, from Zero-Knowledge Proof optimization to decentralized validation networks, address both the technical and industry-specific challenges that have prevented widespread blockchain adoption in music.  
The 320x improvement in proof generation speed isn't just a performance metric; it's the difference between a proof of concept and a production system. It's the kind of optimization that makes decentralized music IP management not just theoretically possible, but practically viable for the thousands of daily transactions that power the global music industry.  
As the blockchain-enabled music licensing market continues its projected growth toward $2.93 billion by 2033, projects like this will serve as blueprints for how to bridge the gap between traditional industry standards and decentralized infrastructure. The future of music IP management is transparent, tamper-proof, and decentralized, and that future is being built today.

From 16 Hours to 3 Minutes: How We Brought Music IP Management to the Blockchain

I believe it’s good to challenge yourself, step outside your comfort zone, and do some not-so-easy theoretical mental exercises. Sometimes for fun, sometimes because you have to, and sometimes both. And that’s exactly how I, an EVM-specialized developer, ended up on a new planet called the XRPL. Initially, the mission seemed simple: create some tokens, then build a type of AMM with extra features, e.g., a min-max swap amount per account restriction. Easy peasy… BUT - the challenge was to do it on the XRPL, the XRP Ledger. So in this article, I invite you to join me on this journey of discovering features and possibilities of the XRP Ledger.

Disclaimer: I’m aware of [the XRPL EVM sidechain](https://www.xrplevm.org/), which is the natural way to go for any EVM-based developer. I also know that Hooks on XRPL are only live on testnet ([as of November 2025](https://xrpl-hooks.readme.io/docs/introduction)). But for the sake of curiosity, let’s check this out anyway. 

### What are Hooks? What’s the idea behind them?
The XRPL Hooks documentation states:
_“Hooks add smart contract functionality to the XRP Ledger: layer one custom code to influence the behaviour and flow of transactions. Hooks are small, efficient pieces of code being defined on an XRPL account, allowing logic to be executed before and/or after XRPL transactions.”_
And honestly, that’s exactly it. Hooks bring smart-contract-like behavior to XRPL accounts and let you run logic before and/or after transactions. Examples range from simple, like “reject payments < 10 XRP”, to more advanced rules like automatically routing 10% of every outgoing payment to a savings account.
### So how do Hooks work under the hood?
First of all, Hooks are WebAssembly modules “installed” on a specific account. That means they can be written in any language that compiles to WebAssembly, though in practice, they’re typically written in C. Hooks in the XRPL world get attached to an account through a SetHook transaction. Once you’ve plugged a Hook in, it basically acts like a smart mini-guardian for that account. It can:
- Step in and either allow or block incoming and outgoing transactions,
- Maintain its own internal state and logic to react based on past events, and
- Even fire off brand-new transactions on behalf of the account.

Hooks on XRPL aren’t Turing-complete by design - no unlimited loops allowed. If you use a loop, you must set a strict maximum. That’s where guards come in. A guard sits at the top of a loop and tells the XRPL the highest number of iterations it could ever run. Maybe it usually loops twice, maybe in extreme cases 500 times - then the guard sets the maximum to 500. XRPL uses this to predict worst-case execution time and calculate the Hook’s fee, keeping everything neat, fast, and predictable.
### Cool, but what if a single Hook isn’t enough? Can I combine a few?
You can - and that’s called a Hook Chain. It’s basically a lineup of up to 10 Hooks on an XRPL account. When a transaction comes in, the chain runs from slot 0 to slot 9, skipping empty slots and treating them as a clean pass. For the transaction to succeed, both the sender and receiver must fully pass their respective Hook Chains. Hooks are added using the SetHook transaction, and when you install one, you can pass parameters that tweak its behavior.
### OK, enough theory. How do I install a Hook?
Simply use the SetHook transaction type. Here’s an example (taken from [the official docs](https://xrpl-hooks.readme.io/docs/sethook-transaction))




```
{ 
    Account: "r4GDFMLGJUKMjNhhycgt2d5LXCdXzCYPoc",
    TransactionType: "SetHook",
    Fee: "2000000",
    Hooks:
    [        
        {                        
            Hook: {                
                CreateCode: fs.readFileSync('accept.wasm').toString('hex').toUpperCase(),
                HookOn: '0000000000000000',
                HookNamespace: addr.codec.sha256('accept').toString('hex').toUpperCase(),
                HookApiVersion: 0
            }
        }
    ]
}
```

Is it also possible to set the array of hooks within a single transaction, like so (the same source as above):



```
{
    Account: "r4GDFMLGJUKMjNhhycgt2d5LXCdXzCYPoc",
    Account: "r4GDFMLGJUKMjNhhycgt2d5LXCdXzCYPoc",
    TransactionType: "SetHook",
    Hooks:                         // This is the Hooks Array
    [            
          {  Hook: { ... }  },     // HookSet Object (position 0)
          {  Hook: { ... }  },  
          {  Hook: { ... }  },  
          {  Hook: { ... }  }.     // HookSet Object (position 3)
    ]
}
```

You can also update or delete Hooks from an account using the same transaction type.
Aaaaand that’s pretty much it! This is just an overview, as there’s a lot more to explore in the mysterious world of Hooks. From this point on, I encourage you to dive deeper yourself. Unfortunately, as mentioned earlier, Hooks don’t seem to be actively developed anymore, with the XRPL team shifting focus toward the EVM sidechain. That’s just my speculation, but regardless, it was really fun to get familiar with this concept. Hope you enjoyed the ride too!

An overview of Hooks on the XRP Ledger, a smart contract functionality that enables developers to add custom logic and automation to XRPL transactions.

I believe it’s good to challenge yourself, step outside your comfort zone, and do some not-so-easy theoretical mental exercises. Sometimes for fun, sometimes because you have to, and sometimes both. And that’s exactly how I, an EVM-specialized developer, ended up on a new planet called the XRPL.

Easy peasy… BUT - the challenge was to do it on the XRPL, the XRP Ledger. So in this article, I invite you to join me on this journey of discovering features and possibilities of the XRP Ledger.

Exploring Hooks on the XRPL: A Developer’s Journey Beyond the EVM

In the rapidly evolving landscape of enterprise blockchain, the XRP Ledger is emerging as a cornerstone platform for institutional decentralized finance. After over a decade of proven reliability, XRPL is experiencing its most transformative phase yet, introducing features that bridge the gap between traditional finance and blockchain innovation while maintaining the speed and efficiency that made it a payments powerhouse.
The numbers tell a compelling story: weekly payment transactions on XRPL have surged 430% from 1.5 million in 2023 to over 8 million in mid-2025 [(Dune Analytics)](https://cryptorank.io/news/feed/e7642-xrp-use-soars-as-payments-hit-60-of-network-activity-in-2025). The network now processes an average of 1.8 million transactions daily [(OKX Research)](https://www.okx.com/learn/xrpl-transaction-volume-interoperability-institutional-innovations), with payment operations accounting for nearly 60% of all network activity. But beneath these impressive metrics lies something even more significant, a fundamental evolution toward institutional-grade DeFi infrastructure that's positioning XRPL as the platform of choice for regulated financial institutions entering the blockchain space.
## What's New on XRPL: A Comprehensive Breakdown
### Multi-Purpose Tokens: The Institution's Answer to Tokenization
The introduction of Multi-Purpose Tokens (MPTs) in version 2.3.0 marks a watershed moment for real-world asset tokenization on XRPL [(XRPL.org)](https://xrpl.org/blog/2024/rippled-2.3.0). Unlike traditional fungible tokens or NFTs, MPTs occupy a unique middle ground - think of them as semi-fungible tokens that can carry rich metadata while maintaining the efficiency and compliance features institutions demand.
Here's what makes MPTs particularly powerful: each token issuance can store up to 1,024 bytes of metadata directly on-chain, including critical information like asset scale, transfer fees, and compliance parameters [(XRPL Documentation)](https://xrpl.org/docs/concepts/tokens/fungible-tokens/multi-purpose-tokens). This on-chain metadata approach means that crucial asset details - expiry dates, warrant numbers, environmental certifications - are permanently recorded and automatically enforceable by the ledger's transaction engine. The institutional compliance features built into MPTs are equally impressive. Issuers can configure granular controls including individual or global freezing capabilities, clawback functionality for recovering tokens from compromised accounts, and authorization requirements that create allowlists of qualified investors. For regulated financial products, these aren't optional features, they're essential safeguards that make blockchain deployment legally feasible.
### Real-Life Use Case: Trade Finance Revolution
FortStock is leveraging MPTs to digitize warehouse receipts as programmable collateral, addressing a critical gap in global trade finance [(XRPL Blog)](https://xrpl.org/blog/2025/fortstock-xrpl-case-study-mpt-standard). Consider this: global trade moves over $25 trillion in goods annually, yet much of this physical inventory remains frozen in financial terms, unleveraged and untapped as collateral. The trade finance gap currently stands between $2.5 and $5 trillion according to the Asian Development Bank and World Trade Organization, disproportionately impacting emerging markets. By representing warehouse receipts as MPTs, FortStock enables a coffee exporter in Colombia to tokenize $1 million worth of stored green coffee beans and use these digital receipts as instant collateral for a loan from a lender in Singapore. The business logic, from issuance to pledge to settlement, is embedded directly in the token, eliminating complex external smart contracts and reducing counterparty risk. The platform successfully tested core functionality on XRPL Devnet and is targeting Q4 2025 for its first major warehouse onboarding and initial loan issuance.
### Real-Life Use Case: Carbon Credit Transparency
Centigrade is using MPTs to bring much-needed transparency to carbon markets by embedding rich environmental data directly into tokenized carbon credits [(Multichain Media)](https://blog.multichainmedia.xyz/index.php/2025/10/10/the-xrpls-multi-purpose-tokens-in-action/). Each token contains comprehensive metadata about the offset project, verification standards, and environmental impact, creating an auditable trail that reduces fraud and builds market confidence. The company has partnered with major verification bodies including the American Carbon Registry and Gold Standard, successfully testing functionality on XRPL Devnet before moving toward live operations.
### Real-Life Use Case: Institutional Money Markets
LiCuido represents shares in money market funds as MPTs, enabling these traditionally illiquid assets to function as instant, programmable collateral for institutional lending. This application demonstrates how MPTs can transform traditional financial instruments into blockchain-native assets while preserving the regulatory compliance and investor protections required in regulated markets.
### Credentials: Building a Compliant Identity Layer
The Credentials standard (XLS-70), approved in September 2025, introduces a lightweight but powerful framework for issuing, managing, and verifying user credentials directly on the XRP Ledger [(Messari Report)](https://messari.io/report/state-of-xrp-ledger-q3-2025). Think of it as building blocks for decentralized identity; credentials can attest to KYC compliance, professional certifications, or qualified investor status, all while preserving user privacy through selective disclosure.
The design draws from the W3C Verifiable Credentials standard but adapts it specifically for the XRPL context [(XRPL Documentation)](https://xrpl.org/docs/concepts/decentralized-storage/credentials). Three new transaction types enable the lifecycle: CredentialCreate allows issuers to mint credentials specifying the subject, credential type, and optional expiration; CredentialAccept lets subjects accept credentials and assume the reserve burden; and CredentialDelete permits either party to revoke credentials at any time. The immediate use case addresses a persistent pain point in blockchain finance: streamlining compliant onboarding. Instead of manually approving each payment sender when using Deposit Authorization, credentials enable automatic approval for accounts holding valid KYC credentials. For tokenized securities or regulated DeFi products, this becomes foundational infrastructure, institutions can restrict access to holders of specific credentials while maintaining privacy and avoiding centralized control.
### Real-Life Use Case: Regulated DEX Access
Permissioned Domains (XLS-80), currently under development, will build on the Credentials standard to enable financial institutions to create controlled environments on XRPL accessible only to credentialed participants. A regulated trading platform could list accepted credentials, such as accredited investor status or institutional KYC verification, granting automatic access to accounts holding any qualifying credential. This architecture enables institutions to participate in DeFi activity while meeting compliance standards for securities trading, AML requirements, and investor protection rules.
### XRPL EVM Sidechain: Bridging Two Ecosystems
The XRPL EVM Sidechain launched on mainnet June 30, 2025, represents a strategic bridge to the Ethereum developer ecosystem [(CoinDesk)](https://www.coindesk.com/tech/2025/06/30/xrpl-evm-sidechain-goes-live-unlocking-ethereum-dapps-in-xrp-ecosystem). Built using the Cosmos EVM stack and connected via the Axelar bridge, the sidechain enables developers to deploy Ethereum-compatible smart contracts using familiar tools like Solidity, MetaMask, and Hardhat, while leveraging XRPL's speed and efficiency.
The architecture is deliberately designed to preserve XRPL's core strengths. The base layer remains optimized for payments, processing up to 1,500 transactions per second with settlement times of 3-5 seconds and fees as low as $0.0002, while the EVM sidechain handles the computational load of programmable applications. XRP serves as the native gas token on both networks, with a 1:1 bridging relationship ensuring value parity. The testnet phase demonstrated remarkable traction, attracting 87 new entities, most with no prior XRP affiliation, including DeFi protocols, oracles, and infrastructure providers [(BeInCrypto)](https://beincrypto.com/xrpl-evm-mainnet-launch-2025/). Since mainnet launch, the sidechain has generated significant developer activity and liquidity inflows, with integration partnerships announced from Band Protocol (oracle services), Grove (RPC infrastructure), Squid (cross-chain asset transfers), and upcoming DeFi applications from Strobe, Securd, and Vertex.
### DynamicNFT: Mutable Tokens for Evolving Use Cases
The DynamicNFT amendment (XLS-46), enabled in June 2025, introduces a new NFTokenModify transaction type that allows metadata updates after minting [(Messari Report)](https://messari.io/report/state-of-xrp-ledger-q3-2025). This seemingly simple addition unlocks entirely new NFT applications: gaming items that evolve with player progress, identity tokens that update with new certifications, event tickets that reflect entry status changes, and supply chain tokens that record each step in a product's journey. Average daily NFT transactions on XRPL increased 51% quarter-over-quarter in Q3 2025, driven by a 71% increase in minting activity. As of September 2025, nearly 17.7 million NFTs have been minted using the XLS-20 standard, with 4.2 million minted in Q3 alone.
### Lower Reserves: Democratizing Access
In December 2024, validators collectively voted to reduce XRPL's reserve requirements by 90% - from 10 XRP to 1 XRP for base account reserves, and from 2 XRP to 0.2 XRP per object owned [(XRPL.org)](https://xrpl.org/blog/2024/lower-reserves-are-in-effect). At current XRP prices around $2.24, this means activating an account now costs approximately $2.24 instead of $22.40, dramatically lowering the barrier to entry. This change has immediate practical implications. Data shows that nearly 600,000 XRPL wallets—representing 8.5% of all accounts, still hold exactly 10 XRP, the previous reserve requirement [(The Crypto Basic)](https://thecryptobasic.com/2025/09/03/data-shows-592818-xrpl-wallets-hold-exactly-10-xrp/). If these dormant account holders return, they can now withdraw 9 XRP (currently worth about $20), leaving only the new 1 XRP reserve. The network has welcomed over 1.17 million new wallets in 2025 alone, bringing total accounts to approximately 7 million as of September.
## The Institutional DeFi Roadmap: What's Coming Next
Ripple's 2025 roadmap focuses squarely on institutional DeFi adoption through regulatory compliance and expanded programmability [(CryptoPolitan)](https://www.cryptopolitan.com/xrp-ledgers-focuses-on-institutional-defi/). Beyond the features already deployed, several initiatives are in development:
- **Extensions** will enable developers to attach custom code to existing XRPL primitives like escrows and AMMs, enhancing functionality without requiring new smart contracts. This modular approach preserves the security and simplicity of native features while allowing customization for specific use cases.
- **Native Lending Protocol** is under development with a $200,000 security Attackathon completed in late 2025, inviting researchers to review over 35,000 lines of C++ code. This protocol will enable crypto-native businesses to integrate lending with Ripple payments, the native DEX, and tokenized real-world assets, all within XRPL's compliance-forward architecture.
- **Permissioned DEX** (XLS-81) extends the credential-gated model specifically to decentralized trading, enabling institutions to participate in on-chain markets while ensuring all participants meet KYC/AML requirements. Combined with existing compliance tools like Authorized Trustlines, freezing capabilities, and clawback functionality, this creates a comprehensive framework for regulated DeFi activity.
## The Competitive Advantage: Why XRPL for Enterprise?
XRPL's appeal to institutional adopters rests on several convergent factors. The platform's 13-year track record demonstrates production-grade reliability, over 70 million ledgers closed without downtime, processing more than 4 billion transactions with consistent sub-$0.01 fees and 3-5 second settlement times. This operational stability matters immensely when moving real financial value. The regulatory clarity achieved in 2025, particularly following the SEC settlement that affirmed XRP's utility status rather than security classification, has unlocked institutional capital. The approval of the first U.S. XRP ETFs brought an estimated $2 billion in new capital, while XRP's listing on Coinbase's Derivatives Exchange in April 2025 paved the way for broader regulated trading products.
The Federated Consensus mechanism eliminates the common blockchain trade-offs between decentralization, security, and speed. Unlike proof-of-work networks with energy concerns or proof-of-stake systems with validator concentration risks, XRPL's consensus protocol enables validators distributed across universities, exchanges, and enterprises globally to reach agreement on transaction ordering without a single point of failure or mining incentive that prioritizes high-fee transactions.
That said, XRPL comes with its own considerations. The base layer's deliberate design choice to prioritize security and stability through simplicity means it doesn't support arbitrary smart contracts like Ethereum or other programmable platforms. The EVM sidechain addresses this gap for developers requiring full smart contract flexibility, but it represents a different security model than the battle-tested base layer. For use cases where native XRPL functionality suffices - payments, DEX trading, tokenization - the base layer's simplicity is actually a strength, reducing attack surface and edge cases. The learning curve for developers transitioning from other blockchain ecosystems can be steep, particularly around XRPL's unique concepts like trust lines, rippling, and the account model. However, extensive documentation, SDKs for JavaScript, Python, and Java, and a growing developer community have significantly improved onboarding. The XRPL Accelerator program, run by Tenity in partnership with Ripple, provides funding and mentorship to startups building on the platform, with cohort 6 launching in June 2025 featuring 9 ventures across payments, trade finance, and AI infrastructure.
## Market Momentum: The Numbers Behind the Narrative
XRP ended Q3 2025 as the fourth-largest cryptocurrency by market capitalization at $170.3 billion, representing 29% quarter-over-quarter growth and outperforming the combined market cap growth of Bitcoin, Ethereum, and Solana [(Messari Report)](https://messari.io/report/state-of-xrp-ledger-q3-2025). The token closed Q3 at $2.85, an all-time high quarterly close.
The XRPL ecosystem shows equally impressive metrics. Over 300 financial institutions have integrated XRP into their operations, leveraging its low-cost, near-instant settlement capabilities [(ainvest.com)](https://www.ainvest.com/news/xrp-ledger-institutional-readiness-post-credentials-upgrade-regulatory-friendly-blockchain-institutional-adoption-2509/). Ripple's On-Demand Liquidity service processed $1.3 trillion in Q2 2025 alone, demonstrating the scale of real-world payment flows moving through XRP corridors. The native DEX now supports over 400 XRP trading pairs with more than 20,000 AMM pools providing direct liquidity. While AMM volumes decreased from their November 2024 peak of $60.5 million daily to an average of $1.7 million daily in Q3 2025, CLOB (Central Limit Order Book) trading has grown, with average daily volume increasing 74% quarter-over-quarter to $13.7 million in Q1 2025 [(Messari Q1 Report)](https://messari.io/report/state-of-xrp-ledger-q1-2025).
Ripple's RLUSD stablecoin, launched in December 2024, reached a combined market cap of $789 million across XRPL and Ethereum by the end of Q3 2025 [(Messari Report)](https://messari.io/report/state-of-xrp-ledger-q3-2025). Notably, the token's distribution is shifting, while over 85% initially deployed on Ethereum [(The Defiant)](https://thedefiant.io/news/blockchains/ripple-debuts-evm-sidechain-to-bring-ethereum-apps-to-xrp-ecosystem), the EVM sidechain launch aims to rebalance issuance toward XRPL's native infrastructure.
## Looking Ahead: XRPL's 2026 Vision
The convergence of regulatory clarity, institutional-grade infrastructure, and real-world adoption positions XRPL uniquely for 2026 and beyond. As traditional financial institutions seek blockchain solutions that balance innovation with compliance, XRPL's combination of proven reliability, embedded compliance tools, and expanding programmability creates a compelling value proposition. The MPT standard is already demonstrating how blockchain can transform traditional assets, from warehouse receipts to carbon credits to money market funds, into programmable financial instruments without sacrificing the compliance controls institutions require. The Credentials framework provides the identity layer necessary for regulated products, while the EVM sidechain ensures Ethereum developers can leverage these capabilities using familiar tools.
For CTOs and decision-makers evaluating blockchain platforms, XRPL represents a mature option that has moved beyond proof-of-concept to production-scale deployment across global payment networks. **With Rumble Fish's expertise in blockchain development and XRPL integration, enterprises can navigate the technical complexities of implementation while leveraging the platform's full potential for payments, tokenization, and institutional DeFi applications.**

XRP Ledger in 2025: Institutional DeFi Takes Center Stage with Game-Changing Updates

A roundup of the most significant and promising zero-knowledge proof projects and implementations to watch in 2025.


In the rapidly evolving landscape of blockchain technology, zero-knowledge proofs are emerging as the fundamental infrastructure for the next generation of scalable, private, and secure decentralized applications. As we navigate through 2025, ZKP technology has moved from theoretical promise to practical deployment, with over $28 billion in Total Value Locked across ZK-based rollups (L2Beat) and the global zero-knowledge proof market projected to reach $7.59 billion by 2033, growing at a remarkable 22.1% CAGR (Grand View Research).

Top 10 Zero-Knowledge Proof Projects Reshaping Blockchain in 2025

One of my very first computer-related memories is the moment I launched the epic game called Deluxe Ski Jump 2. For me, as a kid, it was kind of magic: I was able to double-click on the icon and, a few seconds later, be a pro ski jumper. Over 20 years later, this is still magic, but at least I know what kind of magic is behind it. Let’s talk about desktop apps.

## Framework: A Developer’s Multitool

I also believe that, over 20 years later, building desktop apps is not as cumbersome as it used to be, and there are many great frameworks out there that help to achieve this. First of all, let’s explain, for the sake of clarity, what a framework is. You can think of it as a ready-made toolkit, a set of libraries, tools, and conventions that provide structure for building applications. You can write your app by plugging into the framework’s lifecycle and patterns, which simply makes dev life easier. So far, the most popular framework for building desktop apps has been, and probably still is, Electron, but a new player has entered the game. His name is Tauri.

## My name is Tauri. 2.0 Tauri.

As [Tauri’s official documentation](https://v2.tauri.app/start/) says, _Tauri is a framework for building tiny, fast binaries for all major desktop and mobile platforms._ Sounds cool, doesn’t it? But what does that actually mean? Well, let’s assume you want to build a desktop application for all major platforms: Linux, macOS, and Windows. It’s quite obvious that you want to develop the app codebase once and then just build three different versions suitable for each of the above platforms. This is, of course, about both your backend and frontend code. And here’s where Tauri comes to you and says, _Hello there! Take my hand and let me help you do this!_, which Tauri’s docs explain in other words: _Developers can integrate any frontend framework that compiles to HTML, JavaScript, and CSS for building their user experience while leveraging languages such as Rust, Swift, and Kotlin for backend logic when needed._

## Electron vs. Tauri

But haven’t I just written that there was already a leading framework, Electron, which was doing the same? Yes, but Tauri has a slightly different approach and advantages over the former. Electron is like packing your own mini web browser (Chromium) with your app, so it looks the same everywhere. It’s easy for web developers and has tons of plugins, but it makes apps bigger. Tauri is like borrowing the computer’s built‑in browser to show your app and using a fast Rust helper behind the scenes. Apps are much smaller and often use less memory, but you depend on each system’s web engine.

![electron-vs-tauri.png](https://strapi-uploads-staging-aldnr.rumblefish.dev/electron_vs_tauri_dda10669de.png)

Now that we know the difference, we can decide which framework is better for us and why this is (probably) Tauri. Creating a demo project is a piece of cake, and an officially maintained utility tool guides you by the hand through the first steps of the process. The playground is built; now you can build sandcastles or whatever you want. But don’t forget about security. Fortunately, Tauri hasn’t forgotten and takes security very seriously. The framework provides the Isolation Pattern, which (as the docs say) is a way to intercept and modify Tauri API messages sent by the frontend before they get to Tauri Core, all with JavaScript. The secure JavaScript code that is injected by the Isolation pattern is referred to as the Isolation application. If you’re interested in how it works, I strongly encourage you to take a look [here](https://v2.tauri.app/concept/inter-process-communication/isolation/).

## Summary

Is Tauri the magician who pulls a rabbit (or another Deluxe Ski Jump 2) out of a hat? No. But it's the perfect toolkit for anyone who wants to build a secure cross-platform desktop app. As a full-stack software developer, I had the opportunity to work with it, and I must say I really enjoyed it! Sure, the framework is still not perfect and (fortunately) is still being actively improved, but hopefully in 20 years it will be more mature than I am.

ZKP development is the process of designing, implementing, and deploying zero-knowledge proof systems that enable privacy-preserving verification in blockchain applications. In this guide, you'll learn what ZKP development entails, essential frameworks, and how to build production-ready ZKP applications. This comprehensive guide covers ZKP development fundamentals, popular frameworks (Circom, Noir, gnark), implementation strategies, and real-world deployment examples. Whether you're building privacy-preserving transactions, scalable Layer 2 solutions, or decentralized identity systems, you'll find practical insights for creating secure zero-knowledge protocols. We'll explore how zero-knowledge proofs work in practice, examine proof generation techniques, and demonstrate how to integrate cryptographic proof systems into modern applications while maintaining privacy and ensuring data security.

## Understanding ZKP Development: Key Concepts and Definitions

### Core ZKP Development Concepts

ZKP development centers on creating systems where one party (the prover) can demonstrate knowledge of sensitive information to another party (the verifier) without revealing the underlying data. In practical terms, this involves designing zk circuits, implementing constraint systems, and orchestrating proof generation workflows.

Essential terminology includes R1CS (Rank-1 Constraint System) circuits, which define mathematical relationships, arithmetic circuits that perform computations on private inputs, witnesses containing secret data, and proving keys that enable the creation of cryptographic proofs. The verification process relies on verifying keys to confirm the statement's truth without accessing the underlying information. The distinction between interactive zero-knowledge proofs and non-interactive zero-knowledge approaches is crucial for developers. Interactive proofs require multiple rounds of communication between parties, while non-interactive systems generate standalone proofs suitable for smart contracts and decentralized applications.

### Development Ecosystem Relationships

ZKP development connects directly to blockchain scalability through zk-rollups, privacy through confidential transactions, and identity verification via decentralized identity protocols. Modern proving systems like Groth16 and PLONK integrate with circuit languages such as Circom, enabling developers to build verifiable computations for smart contract applications. The relationship between frontend development tools and backend cryptographic libraries is fundamental. Developers use frameworks like SnarkJS for browser-based proof generation, while libraries like arkworks provide high-performance cryptographic primitives for Rust applications. This ecosystem enables privacy-preserving transactions across decentralized exchanges and maintains transaction privacy in complex financial applications.   

Hash functions, digital signature schemes, and range proofs serve as building blocks for larger zero-knowledge protocols. Understanding how these components interact helps developers optimize proof size, verification time, and overall system performance.

## Why ZKP Development is Important in Blockchain and Web3

Privacy preservation represents the primary driver for ZKP adoption, enabling confidential transactions and private smart contracts without revealing sensitive data. Users can prove possession of funds, verify identity attributes, or demonstrate compliance without exposing proprietary data or risking data breaches. Scalability solutions demonstrate zero-knowledge proofs' transformative impact on blockchain infrastructure. Zk-rollups like Polygon zkEVM and StarkNet reduce Ethereum gas costs by over 90%, processing thousands of transactions per second. These systems compress hundreds of transactions into single cryptographic proofs, dramatically improving throughput and reducing network congestion. Regulatory compliance benefits emerge through privacy-preserving verification mechanisms. Organizations can satisfy GDPR and HIPAA requirements while maintaining data privacy, proving compliance without revealing sensitive information. This approach prevents identity theft and unauthorized access to private information while enabling necessary auditing and verification processes. Major Layer 2 ZKP solutions currently process millions of transactions weekly with billions in total value locked across platforms like Polygon zkEVM, zkSync Era, and StarkNet. Modern verification systems achieve 95% improvements in processing time compared to traditional proof systems.

## Step-by-Step Guide to ZKP Development

### Step 1: Environment Setup and Framework Selection

Installing development tools varies by chosen framework. JavaScript developers should install Node.js (v18+) and npm, then set up Circom with SnarkJS for browser-compatible zero-knowledge proof generation. Rust developers can configure Noir for improved syntax and error handling, while Go developers may prefer gnark for enterprise applications.

For Circom setup, install the compiler and SnarkJS library:

```plaintext
npm install -g circom snarkjs
```

Configure your development environment with recommended VS Code extensions for syntax highlighting and debugging. Set up git hooks for constraint counting and circuit optimization tracking. For production applications, participate in or verify trusted setup ceremonies to maintain security assumptions. Development environment checklist includes: testing framework integration, constraint visualization tools, performance monitoring utilities, and formal verification tools. Establish clear build processes for circuit compilation, key generation, and proof verification to streamline development workflows.

### Step 2: Circuit Design and Implementation

Designing constraint systems requires careful analysis of your specific use case, whether proving age verification, balance proofs, or vote validity. Each logical operation translates to mathematical constraints, directly impacting proof generation time and verification complexity. Writing circuits in Circom syntax involves defining input signals, implementing logic gates, and ensuring proper constraint coverage. Here's a simple example for range proof verification:

```javascript
template RangeProof(n) {
    signal input value;    // Secret value to prove is in range
    signal input min;      // Minimum allowed value
    signal input max;      // Maximum allowed value
    signal output valid;   // 1 if valid, 0 if invalid
    
    // Check value >= min
    component geq = GreaterEqualThan(n);
    geq.in[0] <== value;
    geq.in[1] <== min;
    
    // Check value <= max  
    component leq = LessEqualThan(n);
    leq.in[0] <== value;
    leq.in[1] <== max;
    
    // Both conditions must be true (1 * 1 = 1)
    valid <== geq.out * leq.out;
}
```

Testing circuits with sample inputs and debugging constraint violations prevents production vulnerabilities. Use formal verification tools when available, as under-constrained circuits represent the most common security vulnerability in SNARK applications, potentially allowing false statements to pass verification.

### Step 3: Integration and Deployment

Generating, proving, and verification keys requires executing trusted setups for production circuits. Universal trusted setup approaches like those used in PLONK reduce security risks compared to circuit-specific ceremonies, though they may increase proof size and verification time. Integrating zero-knowledge proof generation into frontend applications demands careful consideration of user experience. Implement web workers to prevent blocking UI threads during proof generation, especially for circuits exceeding 10,000 constraints. Cache generated proofs when possible to avoid repeated computation.

Deploy verifier smart contracts to Ethereum, Polygon, or other EVM-compatible chains using standard deployment tools. Current Groth16 verification costs approximately 150-200k gas (~$5-15 depending on gas prices), while PLONK verification requires around 600-800k gas. Consider Layer 2 deployment for cost-sensitive applications to achieve 90%+ cost reductions.

## Common ZKP Development Mistakes to Avoid

**Under-constrained circuits** represent the most critical security vulnerability in SNARK applications. This occurs when circuits don't properly constrain all possible inputs, allowing malicious provers to generate valid proofs for false statements. Always verify that every logical condition translates to appropriate mathematical constraints, and use formal verification tools to detect potential gaps.

**Trusted setup security failures** occur when developers use development keys in production environments or participate improperly in ceremony processes. Never reuse trusted setups between different circuits, and ensure ceremony participants follow proper security protocols. Consider using universal setups or proof systems without trusted setups (like STARKs or Halo2) for applications requiring long-term security.

**Performance bottlenecks** typically arise from unoptimized constraint counts leading to proof generation times exceeding acceptable user experience thresholds. Profile your circuits early in development, minimize redundant constraints, and consider recursive proof techniques for complex applications. Implement proper error handling for proof generation failures and provide clear progress indicators.

**Frontend integration issues** include blocking main threads during cryptographic operations and inadequate error handling for proof generation failures. Use web workers consistently, implement progress indicators for long-running operations, and provide clear error messages for constraint violations or invalid inputs.

**Pro Tip:** Implement comprehensive testing suites including constraint counting, witness generation validation, and end-to-end proof verification. Use property-based testing and fuzzing techniques to identify edge cases that might compromise security or cause unexpected failures.

    signal input pathElements[levels];
    signal input pathIndices[levels];
    
    signal output nullifierHash;
    signal output commitmentHash;
    
    // Ensure vote is binary (0 or 1)
    component voteCheck = Num2Bits(1);
    voteCheck.in <== vote;
    
    // Verify voter membership in registered set
    component merkleProof = MerkleTreeChecker(levels);
    merkleProof.leaf <== secret;
    merkleProof.pathElements <== pathElements;
    merkleProof.pathIndices <== pathIndices;
    
    // Generate nullifier to prevent double voting
    component nullifierHasher = Poseidon(2);
    nullifierHasher.inputs[0] <== secret;
    nullifierHasher.inputs[1] <== nullifier;
    nullifierHash <== nullifierHasher.out;
    
    // Create vote commitment
    component commitmentHasher = Poseidon(3);
    commitmentHasher.inputs[0] <== vote;
    commitmentHasher.inputs[1] <== secret;

## FAQs about ZKP Development

**Q1: Which ZKP framework should I choose for a DeFi application?** 

A1: Circom with Groth16 offers small proofs (288 bytes) and fast verification, ideal for DeFi applications where gas costs matter. Consider Noir for a better developer experience with improved debugging, or gnark for enterprise applications requiring high performance. For applications needing long-term security without trusted setups, evaluate Halo2 despite larger proof sizes.

**Q2: How long does it take to generate proofs in production?** 

A2: Simple circuits with 1000 constraints generate proofs in 100-2000ms on modern browsers, while complex circuits with 100k+ constraints may require 10-60 seconds depending on device capabilities. Mobile devices typically experience 3-10x slower performance than desktop environments. Consider server-side proving for complex circuits to maintain a good user experience.

**Q3: Can ZKP applications run on mobile devices?** 

A3: Yes, frameworks like SnarkJS support WebAssembly for mobile browsers, enabling on-device proof generation. However, proof generation is significantly slower on mobile devices. For circuits over 10k constraints, consider hybrid approaches with server-side proving or simplified mobile-specific circuits.

**Q4: What are the current gas costs for ZKP verification?** 

A4: Groth16 verification costs approximately 150-200k gas ($5-15 depending on current gas prices), while PLONK verification requires around 600-800k gas. Layer 2 solutions like Polygon reduce costs by 90%+, making frequent verification economically viable. STARKs have higher verification costs (~2-5M gas) but offer post-quantum security.

Understanding Zero-Knowledge Proof Development: Key Concepts and Practical Applications

It’s been a while since my previous article about ZK Proofs. It’s time to see what’s changed since then, what kind of new solutions and blockchains have been developed, and whether the idea of using zk-proofs with the blockchain still makes sense. We’re gonna do this from a new angle - the perspective of L2s! Grab a cup of coffee and lesssssssgo!

## zk-Rollups: The Magic Sauce Behind Scalable Blockchains

Alright, let’s talk about zk-rollups. You might’ve heard this term thrown around in crypto circles, especially if you keep an eye on Ethereum or scaling solutions. But what’s the big deal, and why should you care? So, blockchains, especially the popular ones, are a bit like tiny city centers. Everyone wants to live there, but space is extremely limited, and rent (aka transaction fees) keep increasing. People are sending more and more transactions, firing up complex apps, and, surprise! The main chain gets congested fast. Enter zk-rollups, our scaling superheroes.

zk-rollups are basically clever ways to pack loads of transactions into one neat bundle, do most of the heavy lifting off-chain, and then prove to the main chain: “Hey, we did everything right!” using some cryptographic magic called zero-knowledge proofs (yup, that’s the “zk” part). The chain just checks the proof, saves a bit of summary data, and - boom! - we’ve got space for way more action without breaking a sweat.

## Calldata, Storage, and Why zk-Proofs Are Awesome

Normally, every transaction and its data sit on the blockchain forever. It’s like keeping every grocery receipt since 2015 - messy and potentially expensive. But zk-rollups have a neat trick: they only send the superimportant stuff (called “calldata”) to the chain, while the rest of the data hangs out off-chain, compacted by zk-proofs into tiny packages. What does this mean? Well, instead of needing a truckload of space, you can fit a week’s worth of shopping into your pocket. **zk-proofs let you crunch thousands of transactions into one small proof that anyone can check.** This saves tons of space and makes everything run faster and cheaper. So, if you’re into scaling, zk-rollups are basically a turbo mode for blockchains.

## Projects & Ecosystem: The zk-Rollup Party

A bunch of projects are already rolling (pun intended) with zk-rollups. On Ethereum, you’ve got zkSync, StarkNet, Polygon zkEVM, and more. These guys are all about making things faster, cheaper, and more user-friendly. Solana and other blockchains are also dipping their toes in, tweaking zk-tech to fit their own vibe. But, and this is a big BUT, don’t be fooled. **Just because something uses zk-proofs doesn’t mean it’s private by default.** Most zk-rollups are all about scalability, not privacy. So, your transaction details might still be out in the open. If you’re dreaming of total privacy, you’ll need extra tech (and maybe a different rollup flavor). zk-proofs equal speed and compression, but privacy? That’s a whole other story.

## Overview of the most significant guests of the zk-Rollup Party

Fortunately, in the blockchain universe, there's enough space for many different projects, and some of them have already developed privacy-focused L2s. Let's take a look at a set of examples showcasing how zero-knowledge proofs (ZKPs) are used across different blockchains, highlighting privacy, scalability, and other unique use cases.

## Other worth mentioning, not-ZK-rollup, but still ZK, solutions

-   **Immutable Audit/Compliance**  
    \- Example: Some enterprise or permissioned blockchains use ZKPs to prove compliance or data validity (e.g., KYC checks) without revealing sensitive customer data.
-   **Identity**  
    \- Example: [Privado ID](https://www.privado.id/) uses zk-SNARKs to enable users to prove certain attributes (age, residency, etc.) without revealing the actual data.  
    \- Reason: Privacy, selective disclosure.
-   **Proof of humanity**  
    \- Example: [The World ID](https://world.org/world-id) protocol uses ZKPs and biometric iris scans to verify users as unique individuals without revealing personal information; users can privately prove their verified human status for various actions, with only their uniqueness disclosed.  
    \- Reason: Privacy, selective disclosure.
-   **Voting**  
    \- Example: ZKPs are employed in blockchain voting systems (e.g., [MACI Minimal Anti-Collusion Infrastructure](https://maci.pse.dev/)) to prove votes are valid without exposing voter identity.  
    \- Reason: Privacy, auditability.

ZKPs prove essential for adhering to regulatory requirements as they enable institutions to demonstrate their understanding of client identities (KYC) alongside compliance with anti-money laundering standards (AML), all while safeguarding private information from exposure. This harmony between preserving privacy rights and meeting legal obligations renders ZKPs invaluable within the realm of blockchain systems - whether that concerns validating transactions or upholding data discretion - and illustrates how ZKP technology continues shaping more secure environments conducive to protecting individual data across various blockchain networks.

## Financial Transactions and Confidentiality

In the world of digital finance, keeping financial transactions private is a critical concern. Zero-knowledge proofs enable this privacy by allowing for the verification of transaction authenticity without exposing any specific transaction details. Imagine being able to demonstrate that you have enough money to complete a purchase without having to disclose your total account balance – this is how ZKPs protect delicate financial data.

Take ING as an example. It allows its clients to verify that their income falls within a specified range, yet it does not require them to divulge precise numbers. This advanced method guarantees personal information remains secret while still confirming essential details. By diminishing the expenses associated with safeguarding financial transactions, zero-knowledge proofs render confidential dealings more accessible and cost-effective in settings where regulation is mandatory.

Platforms dedicated to privacy such as Tornado Cash are scrutinized legally because there’s worry about their role in potentially abetting money laundering and other unlawful acts. The U.S. Treasury has gone so far as imposing sanctions on Tornado Cash due to allegations regarding its involvement with state-backed cybercrime schemes. Such developments underscore significant challenges related to ensuring cryptocurrency transaction anonymity while adhering strictly to regulatory standards.

## Secure Online Voting Systems

Imagine an environment in which you can partake in online voting with unwavering trust regarding the security and legitimacy of that activity. Zero-knowledge proofs enable a decentralized approach to casting votes, empowering every participant to authenticate vote validity while maintaining confidentiality. Such advancements place paramount importance on secure data sharing and protected communication within the realm of electronic voting.

Within these ZKP-enhanced electoral frameworks, individuals have the capability to confirm accurate acknowledgment of their ballot without disclosing its particulars. This is actualized via cryptographic methods designed to thwart any interference with votes whilst upholding election integrity. For instance, systems like I-Voting conceal voter identity prior to tallying, reinforcing anonymity protection for each individual’s decision.

By safeguarding personal privacy, these mechanisms diminish potential coercion or intimidation threats, granting electors the freedom to confidently divulge their selections without concern over negative consequences. Zero-knowledge proofs permit third-party auditors independent examination rights concerning electoral procedures and outcomes – bolstering overall transparency as well as reliability within such processes. As illustrated by this advanced technology application example, zero-knowledge proofs hold transformative power over our methodology for managing and securing democratic elections.

## Protecting Healthcare Data Privacy

The protection of healthcare information is paramount to thwart identity theft and prevent data breaches. Zero-knowledge proofs (ZKPs) significantly enhance security within the healthcare sector by allowing authorized entities to share data securely, without exposing any underlying details. This method ensures that while vital information can be accessed when necessary, patient confidentiality remains intact.

For example, MedRec - MIT’s blockchain initiative for medical data sharing - utilizes zero-knowledge proofs to authenticate patient records in a manner that doesn’t compromise sensitive details. By doing so, it guarantees privacy and secures communication channels among healthcare providers who need access only to particular aspects of treatment histories rather than entire medical files. This balances privacy with informational accuracy.

ZKP technology aids in preserving anonymity during collaborative efforts in medical research by facilitating secure data sharing - a process that inherently decreases the likelihood of unauthorized access or breaches occurring as researchers validate shared information. As the emphasis on safeguarding individual privacy grows ever more pressing, ZKP technology emerges as an instrumental tool for shielding delicate health-related information whilst ensuring effective and safe exchanges of such data amongst concerned parties.

## Improving Authentication Mechanisms

Our digital personas are safeguarded by authentication protocols, and Zero-Knowledge Proofs (ZKPs) are revolutionizing the way we establish our identities. By utilizing ZKPs, individuals can confirm their identity without actually disclosing their passwords, which greatly minimizes the likelihood of them being stolen. Imagine accessing your account while keeping your password entirely hidden – that is what zero-knowledge access control offers.

![LinkedIn Post Image (4).jpg](https://strapi-uploads-staging-aldnr.rumblefish.dev/Linked_In_Post_Image_4_9bad2bc646.jpg)

Within biometric security systems, ZKPs enable users to prove who they are without having to store their original biometric information, thereby lessening the possibility of it being stolen. In other words, even if a hacker were able to infiltrate the system for verification purposes, they’d be unable to extract any sensitive biometric data. Zero-knowledge proofs offer a secure and confidential means for confirming one’s identity that allows people to utilize services while maintaining anonymity.

Zero-knowledge proofs give users greater authority over their private information and mitigate concerns linked to breaches of data security and thefts of identity. This advanced cryptographic technique upholds both secure communication channels as well as proper access controls whilst preserving user confidentiality.

## Strengthening Supply Chain Traceability

Ensuring the authenticity and preservation of product quality across a variety of sectors is fundamental, which makes supply chain traceability indispensable. Zero-knowledge proofs play an essential role in authenticating and maintaining data integrity within these supply chains by allowing validation without exposing confidential information. Consequently, consumers are able to confirm product origins while being shielded from full exposure to the intricacies of the entire supply process.

In practice, for example, producers can demonstrate that components conform to specific benchmarks without having to disclose exhaustive details about their supply chain partners. This proves particularly valuable in sectors such as pharmaceuticals and food production where it’s crucial to validate ingredient legitimacy. In this context, ZKPs offer a technique for preserving private information while simultaneously verifying accuracy within the supply chain records.

The adoption of zero-knowledge proof technology allows businesses not only to fortify data integrity but also to bolster secure exchanges along their distribution networks. Such advancements cultivate trust among customers and regulatory agencies by assuring that products adhere to high-quality standards while safeguarding sensitive industry or operational intelligence.

## Powers of Tau Ceremony and Its Significance

The Powers of Tau Ceremony plays a crucial role in bolstering the security framework for Zero Knowledge Proof protocols. By engaging multiple parties in creating a shared reference string, this ceremony minimizes the chances of any individual participant jeopardizing the integrity of the setup. Its significance lies in its assurance that at least one honest actor is involved, which reinforces overall protocol security.

Recent advancements such as optimistic pipelining have revolutionized this procedure by permitting simultaneous contributions from participants, thus expediting the entire process. This has redefined the Powers of Tau Ceremony from an arduous task to a collective and interactive event, boosting engagement and accessibility among users.

With Zero-Knowledge Proofs becoming increasingly popular, ceremonies like the Powers of Tau are indispensable for maintaining cryptographic standards’ credibility. They lay down the critical groundwork necessary for developing highly secure and reliable ZKP applications for future technologies.

## Challenges Faced by Tornado Cash

Tornado Cash, a platform designed to increase privacy through the use of Zero Knowledge Proofs, has encountered substantial legal and security hurdles. As a cryptocurrency mixer, it enables users to obscure their transactions by depositing funds from one account and withdrawing them from another address. This function has sparked concerns regarding its alignment with anti-money laundering laws due to possible connections with unlawful activities.

In an effort to preserve transactional anonymity, Tornado Cash has come under intense examination by government entities because of suspected links with cybercriminal operations backed by nation-states. These issues underscore the fine line that must be navigated between ensuring user privacy in digital currency dealings and complying with regulatory standards.

The situation surrounding Tornado Cash serves as a warning for other platforms prioritizing privacy on the need for stringent security protocols and compliance adherence.
