Zero-Knowledge Proof Development Services
with Rumble Fish
Building privacy-preserving blockchain solutions that scale

16 hours to 3 minutes.

That's how much we reduced ZK-proof processing time for Original Works using RISC Zero and Rust. While others are still talking about possibilities, we're shipping production-ready zero-knowledge solutions that solve real problems for real businesses.

Services
Zero-Knowledge Proof Development with Rumble FishWe build zero-knowledge proof systems that let you verify information without revealing it, enabling private transactions, scalable blockchain solutions, and regulatory compliance without compromising on security. Our team specializes in custom ZK circuit development, rollup implementations, and privacy-preserving smart contracts that work in production environments. Whether you need confidential DeFi protocols, private voting systems, or enterprise blockchain applications, we architect solutions tailored to your specific requirements.
We don't just implement existing protocols; we architect ZK solutions that fit your specific needs. Whether you're building privacy-preserving DeFi protocols, confidential voting systems, or enterprise blockchain applications, we've got you covered.
Our ZK Expertise:
  • SNARKs & STARKs: Deep experience with both approaches. And anything in between.
  • zkEVM Development: Ethereum-compatible zero-knowledge solutions
  • ZK Rollup Implementation: Layer 2 scaling solutions that actually scale
Tired of Ethereum gas fees eating your profits? Our ZK rollup solutions process transactions off-chain while maintaining security guarantees. Think zkSync Era, but custom-built for your use case.
  • 150-300ms confirmation times (yes, really)
  • 99%+ cost reduction compared to mainnet
  • EVM compatibility - your existing contracts work out of the box
  • Bulletproof security with zero-knowledge validity proofs
Build smart contracts that execute without revealing sensitive data. Perfect for:
  • Confidential DeFi: Trading without front-running
  • Private DAOs: Governance without public vote tracking
  • Enterprise Solutions: Business logic that stays confidential
  • Identity Verification: Prove eligibility without exposing personal data
We handle the entire pipeline, from cryptographic protocol design to frontend integration:
  • Backend: Proof generation, verification systems, blockchain integration
  • Frontend: User-friendly interfaces that hide the complexity
  • Infrastructure: Scalable proving services and key management
  • Security: Comprehensive audits and battle-tested implementations

ZK Development Process
Our ZK Development Process
Our development approach combines rigorous cryptographic engineering with practical business requirements, ensuring each ZK system is both mathematically secure and operationally viable. We maintain transparent communication throughout the process, providing regular updates and working prototypes so you can see progress and provide feedback at every stage.
1
Discovery & Architecture
We dive deep into your requirements and design a ZK system that actually makes sense for your business goals. No cookie-cutter solutions.
2
Proof-of-Concept
We build a working prototype to validate the approach. You see results early, we catch issues before they become expensive.
3
Full Implementation
Production-quality code with proper testing, documentation, and security considerations. We optimize for performance from day one.
4
Testing & Audit
Comprehensive testing, including security audits. ZK systems are only as strong as their weakest link.
5
Deployment & Support
We handle deployment and provide ongoing support. Your success is our success.
FAQZero-Knowledge Proof Development Services with Rumble Fish
A: A zero-knowledge proof is a cryptographic method that allows one party (the prover) to prove to another party (the verifier) that they know a specific piece of information, without revealing the actual information itself. Think of it as proving you know the password to a vault without ever saying what the password is. In blockchain applications, ZK proofs enable privacy-preserving transactions, scalable computations, and regulatory compliance. For example, you could prove you're over 18 without showing your birthdate, or prove you have sufficient funds for a transaction without revealing your account balance. The technology maintains three key 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 revealed).
A: Depends on complexity. Simple proofs of concept: 3-4 weeks. Production systems: 3-6 months. We'll give you realistic timelines upfront.
A: When implemented correctly, yes. ZK proofs are mathematically sound and computationally secure. The key is proper implementation—which is where we come in.
A: Modern ZK systems can generate proofs in seconds and verify them in milliseconds. Our Original Works case study reduced processing from 16 hours to 3 minutes.
A: Absolutely. We specialize in integrating ZK proofs into existing systems with minimal disruption to your current architecture.
A: ZK rollups can reduce Ethereum gas costs by 99%+. Even direct mainnet verification is becoming more affordable with protocol improvements.
A: Sure! ZK proofs let you prove something is true without revealing any details about how you know it's true. Like proving you're over 21 without showing your ID.
