Definition ∞ Block dissemination is the process by which newly created blocks of transactions are broadcast across a decentralized network. Once a block is validated by a miner or validator, it is transmitted to other network participants. This ensures all nodes maintain an updated and consistent record of the ledger.
Context ∞ In cryptocurrency networks, efficient block dissemination is critical for maintaining network health, preventing forks, and ensuring rapid transaction finality. News often covers improvements in propagation protocols aimed at reducing latency and increasing network throughput. The speed and reliability of this process directly impact the perceived performance and security of blockchain systems.
