The sequencer receives transactions, orders them, and produces batches that are posted to the base chain. It provides fast, cheap transaction confirmation. Decentralized sequencer designs distribute this role.
Sequencers give rollups their speed and low fees, but centralized sequencers are a trust and liveness concern. Decentralizing sequencing is an active research area. Understanding sequencers is key to L2 evaluation.
