devP2P: Peer-to-Peer Communication Protocol
devP2P is a peer-to-peer communication protocol used in Ethereum for node discovery and data transfer. It allows Ethereum nodes to find each other and communicate directly without third-party servers.
What is DevP2P?
devP2P is a peer-to-peer communication protocol developed specifically for Ethereum. It handles node discovery and data transfer between Ethereum clients and nodes. Some key features of devP2P include:
- Decentralized - Nodes can find each other and communicate directly without centralized servers or infrastructure
- Encrypted connections - Connections between devP2P nodes are encrypted for security
- Multiple transport protocols - devP2P supports UDP, TCP, and WebSocket transports for connections
- Node discovery - Special bootstrap and discovery protocols help nodes find peers and form a mesh network
- Data transfer - devP2P defines protocols for transferring different data like blocks, transactions, receipts between nodes
- Upgradable - The protocol supports introducing new subprotocols over time via capability negotiation
By providing decentralized node discovery and efficient data propagation between Ethereum clients, devP2P serves as the networking backbone of Ethereum that complements the blockchain consensus layer.
