Proof Verification

Definition ∞ Proof verification is the process of confirming the correctness and validity of a cryptographic proof, which attests to the execution of a computation or the integrity of data without re-executing the computation itself. In blockchain, this typically involves a verifier algorithm checking a proof generated by a prover, ensuring that the claimed statement is true according to the protocol rules. This operation is fundamental to scaling solutions like rollups and enhancing privacy features. It provides trustless validation.
Context ∞ Proof verification is a recurring topic in news about layer-2 scaling, zero-knowledge technologies, and the security of decentralized systems. Reports often discuss the efficiency of verification algorithms and their role in reducing computational load on main chains. Advances in proof systems are critical for improving blockchain throughput and enabling more complex, private applications.
