Common app shapes

Rollup precommitments

The domain decides ordered precommitments for a rollup. Consumers store each accepted roll and apply the corresponding state transition policy.

Oracle updates

The domain decides a value for each round. Consumers apply the value only after the roll is verified and past the app's finality window.

Bridge attestations

The domain decides whether an external event was observed. Consumers treat the roll as evidence from BTC-backed operators, not as data availability.

These are patterns, not product limits. A domain is just an ordered stream of verifiable outcomes.
