Definition ∞ Core network function refers to the primary operations a blockchain network executes to maintain its operational integrity and purpose. These essential activities include validating transactions, creating new blocks, and maintaining consensus among participants. Without these functions, the distributed ledger cannot operate as intended. They are foundational to network security and performance.
Context ∞ Discussions about core network function often center on optimization strategies, such as sharding or layer-2 solutions, to enhance transaction throughput and reduce latency. The decentralization and security of these functions are consistently analyzed to guard against potential vulnerabilities. Maintaining efficient and secure core network functions is vital for network health.
