Re-Executing Transactions

Process

Re-executing transactions involves running a previously processed transaction again to confirm its outcome or to reconstruct a specific state. This process is often used in blockchain environments for debugging, auditing, or validating the integrity of state transitions. For instance, in optimistic rollups, a verifier might re-execute a transaction to generate a fraud proof if a sequencer’s proposed state update is suspected to be incorrect. It ensures deterministic outcomes. This process helps maintain system integrity.
