Gossip protocol is the quiet engine behind blockchain P2P networks, spreading transactions and blocks through random, peer-to-peer exchanges. It's simple, resilient, and scales logarithmically-making it ideal for decentralized systems like Bitcoin and Ethereum.
Peer-to-peer networks are the decentralized backbone of blockchain, letting thousands of computers share and verify data without central servers. This is what makes Bitcoin and Ethereum secure, censorship-resistant, and always online.
