leader-DAG Spectrum

Definition ∞ The leader-DAG spectrum refers to the range of Directed Acyclic Graph structures that incorporate a leader election mechanism for ordering transactions or proposing blocks. This spectrum encompasses various designs where a designated leader or set of leaders is responsible for specific aspects of block creation. It blends elements of leader-based consensus with the parallel processing capabilities of DAGs.
Context ∞ In advanced distributed ledger technologies, the leader-DAG spectrum is a subject of research and development aimed at optimizing transaction throughput and finality. News in this area often highlights new consensus models that seek to leverage the benefits of both leader-driven efficiency and DAG-based parallelism. Understanding this concept helps interpret discussions on next-generation blockchain architectures and their performance characteristics.
