ZK-Proof

Definition

A ZK-proof, or zero-knowledge proof, is a cryptographic method by which one party can prove to another that a given statement is true, without revealing any information beyond the truth of the statement itself. This technology is vital for privacy-preserving applications and for enhancing the scalability of blockchains by enabling off-chain computations to be verified on-chain without re-executing them. ZK-proofs are foundational for solutions aiming to balance transparency with confidentiality. They are categorized into interactive and non-interactive forms.
