Prover Latency

Prover latency is the time required for a node to generate a cryptographic proof for a specific set of transactions. In high-frequency trading environments, this is a critical bottleneck because trading decisions must be executed and finalized in milliseconds.

High prover latency can lead to stale prices or delays in margin requirement updates, which increases systemic risk. Reducing this latency involves optimizing circuit design, utilizing hardware acceleration like FPGAs or ASICs, and parallelizing the computation of the proof.

If prover latency is too high, the protocol cannot maintain the responsiveness required for competitive derivative markets. It is the primary constraint on the speed of ZKP-based rollups.
