Zero-Knowledge Proofs

Definition ∞ Zero-knowledge proofs are cryptographic methods that allow one party to prove to another that a statement is true, without revealing any information beyond the validity of the statement itself. They are fundamental to enhancing privacy and scalability in blockchain systems. These proofs ensure data integrity without disclosing sensitive details.
Context ∞ The application and advancement of zero-knowledge proofs are frequently highlighted in news concerning blockchain privacy and scaling innovations. Current research and development focus on improving the efficiency and applicability of various ZK-proof constructions, such as ZK-SNARKs and ZK-STARKs. Their integration into protocols is seen as a significant step towards more private and performant decentralized systems.
