The Optimism security model relies on optimistic validation, where transactions are assumed to be valid unless proven otherwise during a challenge period. This system uses fraud proofs, which allow any network participant to submit a proof to the Layer 1 chain if they detect an invalid state transition. The proof re-executes the disputed transaction on Layer 1 to determine its correctness, ensuring the integrity of the Layer 2 state.
Incentive
The economic incentive structure is critical to the security model, requiring sequencers to post a bond as collateral for their proposed state updates. If a fraud proof successfully challenges a state transition, the sequencer’s bond is slashed, and the challenger receives a portion of the forfeited collateral as a reward. This mechanism financially penalizes malicious behavior and incentivizes honest participation.
Finality
A key characteristic of the Optimism security model is the challenge period, which introduces a delay before transactions achieve finality on Layer 1. This delay is necessary to allow time for fraud proofs to be submitted and processed. While this impacts the speed of withdrawals from Layer 2 to Layer 1, it ensures that the Layer 2 network inherits the full security guarantees of the underlying Ethereum blockchain.
