Fraud Proof Challenge Period

Mechanism

A fraud proof challenge period is a designated time window in optimistic rollup systems during which participants can submit a cryptographic proof of fraudulent or incorrect state transitions. This mechanism is central to the security model of optimistic rollups, allowing honest network participants to identify and challenge invalid computations performed by a sequencer. If a valid fraud proof is submitted and verified, the incorrect state transition is reverted. This period provides a crucial defense against malicious sequencer behavior.
