Online Verification Efficiency

Definition ∞ Online verification efficiency measures how quickly and with how few computational resources a cryptographic proof can be checked by a verifier in a live network environment. High efficiency is critical for scalable blockchain applications, where verification occurs on-chain. It directly impacts transaction throughput and the associated costs.
Context ∞ Improving online verification efficiency is a primary goal in the development of zero-knowledge proof systems for blockchain scaling. Faster and cheaper verification allows for more transactions to be processed and validated on a layer-1 blockchain, reducing congestion and fees. Innovations in proof construction, such as those leading to constant complexity proofs, directly contribute to enhancing this crucial metric for digital asset networks.
