    What is Zero-Knowledge Proof (ZK)?

    ज़ीरो-नॉलेज प्रूफ
    A 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.
