Block Propagation

Block propagation is the process through which a newly mined or validated block is transmitted to other nodes in a blockchain network. Once a miner or validator finds a valid block, it must be quickly shared across the network so other participants can update their ledgers and continue building on the most recent chain state. Efficient propagation is critical to minimize orphaned blocks, maintain consensus, and ensure network performance. Techniques like compact block relay, Graphene, and gossip protocols help optimize propagation speed and reduce bandwidth usage.
