Prover Verifier Model

Definition ∞ The Prover Verifier Model describes a fundamental interaction in cryptography where one party, the prover, attempts to convince another party, the verifier, that a statement is true. The prover generates a proof, and the verifier checks its correctness, typically without needing to re-execute the entire computation. This model is essential for zero-knowledge proofs and other verification systems. It allows for efficient and secure validation of complex claims.
Context ∞ The prover verifier model is a foundational concept in the technical explanations of zero-knowledge proofs and other cryptographic proof systems that appear in crypto news. Discussions about blockchain scalability, privacy solutions, and layer-2 protocols frequently reference this interaction. The efficiency of the prover’s proof generation and the verifier’s proof checking time are critical metrics analyzed in these contexts.
