Base Sequencing

Definition ∞ Base Sequencing refers to the ordering and inclusion of transactions on a layer-1 blockchain, which serves as the foundational settlement layer. This process determines the definitive sequence in which operations are recorded and confirmed across the network. It establishes the ultimate source of truth for all data and transactions processed by dependent layer-2 solutions. The integrity of this sequence is vital for the overall security and finality of the blockchain system.
Context ∞ Base Sequencing is a central discussion point in news covering blockchain scalability solutions and data availability layers. Its efficiency and reliability directly influence the performance and trust assumptions of layer-2 protocols. Innovations in this area aim to optimize transaction ordering and reduce latency on primary networks.
