Block Propagation
The process of distributing a newly produced block from the leader to all validators in the cluster. Solana uses Turbine for fast propagation—the leader shreds the block, erasure-codes the shreds, and feeds them into the Turbine tree. Target propagation latency is under 200ms for the full cluster.
