Rollup

A scaling system that links off-chain execution to a base layer using published information and a proof or challenge mechanism.

A concrete example

A quick sequencer receipt can precede stronger base-layer settlement guarantees.

In context

A sequencer may provide a quick receipt before Ethereum settlement gives stronger guarantees. Native withdrawals from optimistic systems may include a challenge period. A liquidity bridge can offer a faster route by adding a separate provider or pool, with additional fees and risks.
