Leader-Based Coordination

Definition ∞ Leader-based coordination is a system where a designated node or entity directs the actions of other participants to achieve network-wide agreement. This approach contrasts with fully decentralized models by introducing a central point of direction. Such mechanisms are often employed to enhance transaction processing speed or simplify network operations.
Context ∞ Discussions of leader-based coordination appear when analyzing specific blockchain consensus algorithms, particularly those aiming for high throughput. News might report on the selection, rotation, or potential vulnerabilities associated with designated leaders in a network. Understanding this coordination method is key to evaluating the trade-offs between decentralization and performance in distributed systems.
