Sequencer Responsibility

Action

Sequencer responsibility fundamentally concerns the ordered execution of transactions within a Layer-2 scaling solution, particularly rollups. This involves selecting transactions from a mempool, arranging them into blocks, and submitting proofs of validity to the Layer-1 chain. Effective action by the sequencer directly impacts transaction throughput and finality times, influencing the user experience and overall network performance. The sequencer’s actions are governed by the protocol rules and any pre-defined prioritization mechanisms, ensuring a consistent and predictable state transition.
