A few points to note about the two types of proofs used by Rollups:
1) Many fraud proofs use an interactive dispute process: the two parties repeatedly narrow down the scope of their disagreement, until a single step needs to be re-executed on the mainnet to determine who is right.
2) Withdrawing from an Optimistic Rollup to the mainnet via the official bridge usually takes about 7 days. This period is the challenge window for fraud proofs.
3) Before using a Layer 2 network, you can check L2BEAT’s Stage rating and risk warnings for it. The higher the stage, the less it depends on the team.
$ARB is the governance token of Arbitrum, an Optimistic Rollup network that uses fraud proofs.
