Polylogarithmic Verifier

Definition

A polylogarithmic verifier refers to a cryptographic proof system where the computational effort required by the verifier to check a proof scales polylogarithmically with the size of the computation being proven. This efficiency is highly desirable for scalability, as it means verification costs increase very slowly, even for extremely large computations. Such verifiers are central to constructing efficient zero-knowledge proofs and verifiable computation schemes. They permit light clients to validate complex operations with minimal resources.
