Designated Verifier

Definition ∞ A Designated Verifier is a specific party authorized to verify a cryptographic proof, typically without revealing the underlying secret information to others. This concept is particularly relevant in zero-knowledge proof systems where a prover demonstrates knowledge to only one designated entity. It ensures confidentiality by limiting the scope of proof verification to an intended recipient. Such verifiers are crucial for privacy-preserving protocols and selective disclosure of credentials.
Context ∞ Discussions surrounding Designated Verifiers often address their application in regulated digital asset environments, where selective disclosure of identity or transaction details is necessary for compliance. A key debate centers on balancing privacy protection with the need for auditability by authorized parties. Future developments will likely include advanced cryptographic constructions that offer greater flexibility in defining and changing designated verifiers. News articles frequently highlight how this technology enables confidential transactions and secure data sharing in blockchain applications.
