How does the mainnet know that the results submitted by a Rollup are correct?
Many fraud proofs use an interactive dispute process: both sides progressively narrow down where they disagree, and in the end, just one step needs to be re-executed on the mainnet to determine who's right.
Withdrawing from an Optimistic Rollup to the mainnet via the official bridge generally takes about 7 days. This period is the challenge window for fraud proofs.
The key thing to remember when managing funds: factor in the roughly one-week challenge period before withdrawing from an Optimistic Rollup. Don't wait until the last minute to withdraw money you need urgently.
