As soon as the rollup posts transaction data on the data availability layer, rollup nodes can compute the new state root of the rollup and finality is achieved within the realm of the rollup.

DA Layers.

Cool to see innovation in the space

Key point on why DA is important

"Once something is past the fraud proof window for your optimistic rollup and it couldn't be contested anyway, what's the value in paying to store it forever?"

Data Availability (DA) – Ensuring the transaction data behind rollup block headers has been published and made available so that anyone can recreate the state.
