- Cascade propagation: a node tells its neighbors, they tell theirs — information spreads exponentially.

Cascade propagation: a node tells its neighbors, they tell theirs — information spreads exponentially.

Both new transactions and newly created blocks propagate this way.

Primarily over TCP — reliable, ordered delivery is critical for reconstructing blocks correctly.

Bootnode initiates the cascade by introducing new nodes to a subset of peers.

Fully decentralized — no central broadcaster, no single point of failure.
