Definition ∞ Proving time denotes the duration required for a prover to generate a cryptographic proof demonstrating the correctness of a computation or statement. This metric is a key performance indicator for zero-knowledge proof systems. A shorter proving time indicates greater efficiency and practical utility for real-world applications. It is distinct from the time taken to verify the proof.
Context ∞ Proving time is a critical bottleneck in the scalability of many blockchain solutions that rely on zero-knowledge proofs, such as ZK-rollups. Researchers and developers continuously work to reduce proving time through algorithmic improvements and hardware optimizations. Decreasing this time is essential for increasing transaction throughput and lowering costs on layer-2 networks. Faster proving enables more responsive and scalable decentralized applications.
