Definition ∞ Delegatable proofs are cryptographic proofs that can be securely transferred or delegated from one party to another without requiring the original prover to re-execute the computation. This capability allows a verifier to present a proof to a third party, who can then verify the statement’s validity without needing direct interaction with the initial prover. Such proofs significantly enhance efficiency and privacy in complex verification scenarios. They reduce redundant computations and facilitate auditability in multi-party systems.
Context ∞ Delegatable proofs are gaining prominence in the context of scalable blockchain solutions and privacy-preserving protocols, particularly in zero-knowledge proof systems. Their utility is often discussed in relation to off-chain computation verification and the creation of verifiable credentials that can be shared selectively. Ongoing research aims to optimize their construction for various cryptographic primitives, expanding their practical applications in decentralized identity and secure computation.
