Peer-to-Peer Protocols
Peer-to-peer (P2P) protocols are communication protocols that enable direct data exchange between devices (peers) in a decentralized network, without relying on a central server. They allow peers to share resources like files, bandwidth, or processing power, forming distributed systems where each node acts as both client and server. This architecture is fundamental to applications like file sharing, blockchain networks, and real-time communication.
Developers should learn P2P protocols when building decentralized applications that require resilience, scalability, and reduced reliance on central infrastructure, such as in distributed file-sharing systems like BitTorrent or decentralized finance platforms. They are essential for creating censorship-resistant networks, improving fault tolerance, and enabling direct user-to-user interactions in scenarios like video conferencing or IoT device communication.
