Definition ∞ Proof verification time refers to the duration required for a blockchain network or a verifier to cryptographically confirm the validity of a transaction or a block. This period is crucial for ensuring the security and integrity of the distributed ledger. Faster verification times contribute significantly to the overall scalability and efficiency of a blockchain system. It directly impacts transaction finality.
Context ∞ The concept of proof verification time is central to discussions on blockchain scalability solutions, such as zero-knowledge rollups, often highlighted in crypto news. Reducing this time is a primary goal for developers aiming to enhance network throughput and user experience. Advancements in cryptographic techniques consistently seek to optimize this critical performance metric.
