What is Zero-Knowledge Proof (ZK)?
ज़ीरो-नॉलेज प्रूफA zero-knowledge proof lets you prove something is true without revealing the underlying data. It's used for privacy and scaling (zk-rollups like zkSync and Scroll).
Full Explanation
Zero-knowledge proofs are a cryptographic technique where a prover can convince a verifier that a statement is true without revealing any information beyond the truth of the statement. In crypto, ZK proofs power: zk-rollups (batch thousands of transactions, prove their validity with a single proof on L1 — massive scaling), privacy coins (Zcash), and identity verification without revealing personal data. zkSync, Scroll, Polygon zkEVM, and StarkNet all use ZK technology.
