Zero-Knowledge Proof
Also known as: ZKP, Private Proof, Zero Knowledge Protocol
A method by which one party proves to another that a statement is true without revealing the underlying information.
A Zero-Knowledge Proof (ZKP) is a cryptographic method that enables a prover to convince a verifier that a given statement is true without disclosing any additional information. ZKPs are foundational to privacy-preserving systems in blockchain, allowing transactions and identities to be verified without revealing their content. There are interactive and non-interactive forms of ZKPs, with implementations in privacy coins (Zcash), ZK-rollups, and decentralized authentication. ZKPs improve security, reduce data exposure, and enable private yet verifiable blockchain interactions.
