In an optimistic rollup, what is the purpose of the "challenge period" (dispute window)?
Correct! Well done.
Incorrect.
The correct answer is A) It gives participants time to submit a fraud proof if a posted state transition is invalid, before the result is considered final on Layer 1
A
Correct Answer
It gives participants time to submit a fraud proof if a posted state transition is invalid, before the result is considered final on Layer 1
Explanation
Optimistic rollups assume state transitions are valid by default, but allow anyone to submit a fraud proof during the challenge window; only after this period (commonly ~7 days) is withdrawal to L1 finalized without challenge.
