NP Verification

Definition

NP verification refers to the process of efficiently checking the correctness of a solution to a problem that belongs to the complexity class NP, or non-deterministic polynomial time. While finding a solution might be computationally hard, verifying a proposed solution can be done quickly. In cryptography, this principle is crucial for zero-knowledge proofs, where a prover demonstrates knowledge of a secret without revealing it, and the verifier efficiently confirms its validity. This concept underpins many privacy-enhancing technologies in blockchain.
