Definition ∞ Zero-knowledge attestation is a cryptographic proof where one party can confirm the truth of a statement to another party without revealing any additional information beyond the truth of the statement itself. This method allows for verification of credentials or data without exposing the underlying sensitive details. It is a key technology for privacy-preserving applications.
Context ∞ Zero-knowledge attestations are gaining prominence in blockchain and digital identity solutions, addressing critical privacy concerns. News often highlights new protocols or applications that leverage zero-knowledge proofs to enable confidential transactions or verifiable digital identities. This technology is instrumental in balancing transparency with privacy requirements in decentralized systems.
