Why should the mainnet trust the results submitted by a Rollup?
Optimistic Rollups initially assume that submitted results are correct. During the challenge period, anyone can submit a fraud proof to challenge them.
Many fraud proofs use an interactive dispute process: both sides gradually narrow down where they disagree, until the mainnet only needs to re-execute one step to determine who is right.
The most important thing to remember when managing funds: allow about a week for the challenge period before withdrawing from an Optimistic Rollup. Don’t wait until the last minute to use the official bridge for money you need urgently.
