Optimistic rollup finality refers to the process by which transactions on a layer-2 rollup are considered irreversible on the layer-1 blockchain. Unlike immediate finality, optimistic rollups assume all transactions are valid by default. Finality is achieved only after a specific challenge period has passed without a successful fraud proof being submitted.
Rollup
Optimistic rollups are layer-2 solutions that process transactions off-chain and batch them for submission to the main chain, significantly increasing throughput and reducing gas costs. The optimistic assumption allows for faster transaction processing compared to zero-knowledge rollups.
Challenge
The challenge mechanism introduces a time delay, typically several days, during which a user can submit a fraud proof to contest a transaction. This delay creates a specific risk profile for derivatives platforms built on optimistic rollups, as withdrawals and settlements are not truly final until the challenge window closes.
