Definition ∞ A block synchronization protocol outlines the rules and procedures for network nodes to update their local copies of a blockchain. This protocol enables new nodes to join the network and existing nodes to catch up on missed blocks. It ensures all participants maintain an accurate and identical ledger state.
Context ∞ Block synchronization protocols are essential for the integrity and functionality of all blockchain networks, impacting how quickly new participants can access the full transaction history. Developments in these protocols are frequently reported in crypto news, especially when they promise faster onboarding for new nodes or improved network resilience. The efficiency of synchronization directly influences network decentralization and overall system health.
