Package com.privatechain.network.gossip

package com.privatechain.network.gossip

Transaction gossip and block broadcast — propagates newly submitted transactions and mined blocks to connected peers (FR-NET-02, FR-NET-03).

Classes in this package:

• GossipProtocol — on BlockchainEvent.TransactionSubmittedEvent, forwards the transaction to ceil(log2(n)) randomly selected peers (configurable fan-out k). This logarithmic fan-out achieves full network coverage in O(log n) hops.
• BlockBroadcaster — on BlockchainEvent.BlockAddedEvent, pushes the serialized block to all connected peers simultaneously.

Since:

1.0.0
