Sequencer Design Considerations

Architecture

Sequencer design fundamentally concerns the system’s ability to process transactions efficiently and maintain network consensus within a Layer-2 scaling solution. Optimal architecture balances throughput requirements with the computational cost of fraud proofs and data availability sampling, directly impacting transaction finality times. Considerations include the choice of data structures, the sequencing node’s hardware specifications, and the communication protocols employed for interaction with the Layer-1 chain, all of which influence the system’s resilience to congestion and potential attacks. A robust architecture prioritizes deterministic execution and minimizes latency to ensure a positive user experience and maintain competitive positioning.
