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