Arbitrum’s security model is fundamentally based on an optimistic rollup architecture, where transaction execution occurs off-chain to achieve high throughput and reduced gas costs. The system relies on a sequencer to aggregate transactions into batches and submit the resulting state root to the Ethereum Layer 1 blockchain. This design assumes all transactions are valid by default, allowing for rapid processing on the Layer 2 network.
Validation
The core security mechanism involves a challenge period during which any participant can submit a fraud proof if they detect an invalid state transition. This proof requires re-executing the disputed transaction on Layer 1 to verify its correctness. If the fraud proof is successful, the malicious sequencer or validator loses their staked bond, and the correct state transition is enforced.
Incentive
The economic incentive structure underpins the security model by requiring sequencers to stake collateral as a financial guarantee against fraudulent activity. This bond mechanism ensures that honest behavior is financially rewarded, while successful challengers receive a portion of the forfeited stake. This creates a self-policing system where participants are incentivized to maintain the integrity of the Layer 2 state.
