Leader Based

Definition ∞ Leader Based describes a consensus design where a specific node or a small group of nodes is temporarily selected to propose new blocks or validate transactions. This selection process is typically periodic, granting a designated leader the authority to order and submit data. It contrasts with peer-based systems.
Context ∞ This design approach is often discussed in relation to blockchain performance and decentralization trade-offs. News concerning high-throughput blockchain protocols or specific consensus algorithms may highlight their leader-based nature. While it can enhance speed, considerations around leader rotation and fault tolerance remain central.
