Sequencer Decentralization

Definition ∞ Sequencer Decentralization refers to the process of distributing the responsibility for ordering and submitting transactions to the main blockchain among multiple independent entities within a rollup system. This aims to remove a single point of control and potential censorship or manipulation. It enhances the security and censorship resistance of layer-2 solutions.
Context ∞ Sequencer decentralization is a significant topic in the evolution of rollup technologies, particularly for optimistic and ZK-rollups. News reports often discuss efforts by various projects to move away from centralized sequencers to improve censorship resistance and reduce single points of failure. This development is crucial for ensuring the long-term integrity and trustlessness of layer-2 scaling solutions.
