Zero-Knowledge Proof (ZK)
Cryptographic proof that a statement is true without revealing the underlying data — basis for ZK-rollups and privacy.
Definition
A zero-knowledge proof allows one party to prove to another that a statement is true without revealing any information beyond the validity itself. Used in ZK-rollups for scaling, privacy coins, and emerging compliance use cases (proof of solvency, proof of credentials).
