Sequencer Role Centralization

Architecture

Sequencer Role Centralization, within Layer-2 scaling solutions, represents a fundamental shift in transaction ordering and block proposal processes. This centralization introduces a single point of coordination, impacting censorship resistance and potential systemic risk, particularly in rollup-based systems. The architecture’s efficiency stems from consolidating these functions, reducing on-chain data requirements and enhancing throughput, but necessitates robust mechanisms for sequencer selection and fault tolerance. Consequently, the design of this architecture directly influences the trade-off between scalability and decentralization, demanding careful consideration of economic incentives and governance models.
