Sequencer Centralization

Architecture

Sequencer centralization, within cryptocurrency and derivatives, describes a system where order flow and transaction inclusion are predominantly managed by a limited number of entities, impacting network decentralization. This contrasts with a fully distributed model where numerous independent nodes compete to propose and validate blocks. The concentration of sequencing power introduces potential single points of failure and censorship, influencing the efficiency and security trade-offs of Layer-2 scaling solutions. Understanding this architecture is crucial for assessing the trust assumptions inherent in various blockchain designs and their susceptibility to external influence.
