Quasi-Logarithmic Verification

Definition

Quasi-logarithmic verification describes a cryptographic proof system where the time needed to verify a computation is nearly proportional to the logarithm of the computation’s original execution time. This advanced verification method significantly reduces the computational resources required for proof checking compared to re-executing the entire computation. It is particularly relevant for scaling blockchain networks, as it allows for the efficient verification of complex off-chain computations without sacrificing security. Such systems enable a single, small proof to confirm the correctness of a very large amount of work, making them suitable for zero-knowledge rollups and other scaling solutions.
