What is Libp2p?

Libp2p is a modular network stack of protocols, libraries, and specifications built for peer-to-peer (P2P) applications and systems that allows developers to make use of plug-and-play networking within their distributed applications. The system began as the networking layer for the InterPlanetary File System (IPFS), but later evolved into its own project. It is built to solve problems related to data transport, digital identity, security, routing, content discovery, and other uses. Libp2p has implementations in JavaScript, Go, Rust, Python, and C++.
