Definition ∞ Prover Liveness Guarantees are assurances that the entities responsible for generating cryptographic proofs will remain active and available to perform their duties. These guarantees are essential for the continuous operation and finality of systems relying on verifiable computation. Economic incentives and penalties often support these assurances. This ensures timely proof submission.
Context ∞ Maintaining prover liveness is critical for the reliable functioning of zero-knowledge rollups and other proof-based scaling solutions, as delays in proof generation can stall transaction finality. Network designs frequently incorporate staking mechanisms and reputation systems to incentivize consistent prover participation. Ensuring these guarantees is vital for user experience and system integrity.
