What the explainer covers

• How a sequencer orders transactions into a batch.
• Where the batch data goes, and why a dedicated data-availability layer changes the cost.
• The difference between a validity proof and a fraud-proof window.
• What “finality” means for a user waiting to withdraw.

Companion reading: the Rollup and Sequencer glossary entries, the Corridor roadmap in Corridor publishes a three-stage roadmap to decentralise its sequencer, with a permissionless set by year end, and the Lattice launch in Lattice goes live as a dedicated data-availability layer, and six fictional rollups say they will switch.
