Prover Batching

Definition ∞ Prover batching is a technique used in zero-knowledge proof systems where multiple individual proofs are combined into a single, aggregated proof. This process significantly reduces the computational cost and data size required for verification. It enhances the efficiency and scalability of systems that rely on frequent proof generation. The aggregated proof retains the security properties of individual proofs.
Context ∞ In blockchain scalability solutions, particularly those utilizing zero-knowledge rollups (ZK-rollups), prover batching is a critical optimization. It allows many transactions to be processed off-chain and then proven with a single, compact proof submitted to the main chain. News frequently discusses how this technique improves transaction throughput and lowers gas fees on networks like Ethereum, advancing the adoption of layer-2 solutions.
