Peer-to-Peer

Peer-to-peer (P2P) is a decentralized network architecture where participants (peers) directly share resources, such as files, data, or computing power, without relying on a central server. It enables distributed systems where each node can act as both a client and a server, facilitating direct communication and resource exchange. This model is foundational for applications like file sharing, blockchain networks, and collaborative computing.

Also known as: P2P, Peer to Peer, Peer-to-peer networking, Decentralized network, Distributed peer network

Why learn Peer-to-Peer?

Developers should learn P2P concepts when building decentralized applications that require resilience, scalability, and reduced dependency on central authorities, such as in distributed file-sharing systems like BitTorrent or cryptocurrency networks like Bitcoin. It's also valuable for creating collaborative tools, content delivery networks, and IoT systems where direct device-to-device communication enhances efficiency and fault tolerance.
