The technology of peer-to-peer (P2P) networking enables decentralized communication and data sharing between devices without the need for a central server. In a P2P network, each participant (or peer) can act as both a client and a server, allowing for direct exchange of resources, files, or services. This technology is foundational in applications such as file sharing, cryptocurrencies like Bitcoin, and collaborative platforms. P2P networks can enhance scalability and resilience, as they distribute load and reduce reliance on centralized infrastructure.
