Optimistic rollup
A rollup that accepts submitted execution results subject to a process for challenging invalid results.
In more detail
Optimistic here describes how a submitted result is treated, not an expectation that token prices rise. Results can be disputed during a defined window using the protocol's challenge mechanism. Available data and effective challengers are important, and standard withdrawals may need to wait for that dispute window to end.
How you might use it
A challenger spots an incorrect state update and disputes it while the optimistic rollup's challenge window is still open.
