Zero-Knowledge Proof Playground
Zero-Knowledge Proofs (ZKPs) allow someone to prove they know a secret — without revealing it. This playground simulates that with a simple password hash comparison.
How it works
- Enter a secret and save the hash (simulates a verifier storing a commitment).
- Later, prove you know the secret by submitting it again (the verifier compares hashes).
- The secret is never stored or shown publicly.
Why ZKPs matter in crypto
- Privacy: ZKPs let you prove something (like your age or balance) without revealing the actual value.
- Efficiency: Used in zkRollups to prove entire batches of transactions are valid without sending all data.
- Security: No one can learn your secret — only that you know it.
ZKPs are used in zkSync, StarkNet, Zcash, Semaphore, and more.
