A sequencing committee is a designated group of participants responsible for ordering and finalizing transactions within a specific blockchain or decentralized system. This entity plays a role in determining the sequence of operations, which is critical for preventing front-running and ensuring fair transaction inclusion. It can be a centralized or decentralized group, depending on the protocol design. This component helps maintain integrity and order in transaction processing.
Context
The concept of a sequencing committee is often discussed in the context of layer-2 scaling solutions and specific decentralized finance protocols that require a controlled transaction ordering. News articles may analyze the trade-offs between decentralization and efficiency when implementing such a committee. The design and governance of these committees are key areas of interest for ensuring censorship resistance and fairness in transaction processing.
