Proof Verification Cost

Definition ∞ Proof verification cost represents the computational resources, typically measured in gas or processing time, required to validate a cryptographic proof on a blockchain. This cost is a critical factor in the efficiency and scalability of systems utilizing zero-knowledge proofs or other complex cryptographic attestations. Lower verification costs allow for more transactions or complex computations to be processed on-chain. It directly impacts network fees and throughput.
Context ∞ Proof verification cost is a central technical discussion in the development of Layer 2 scaling solutions and privacy protocols, frequently appearing in crypto news. Innovations in proof systems, such as advancements in SNARKs and STARKs, often aim to reduce this cost to make these technologies more practical. The economic viability of many advanced blockchain features hinges on minimizing the resources needed for proof validation.
