libp2p is a modular peer-to-peer networking stack and protocol suite, originally extracted from IPFS, with implementations in Go, Rust, JavaScript, and other languages. go-libp2p is the Go implementation, providing transports (TCP, QUIC, WebSocket, WebRTC), encrypted connections, stream multiplexing, peer discovery, and NAT traversal for building decentralized applications.

Use cases

• build a peer-to-peer file sharing application
• connect nodes in a decentralized network without central servers
• implement NAT traversal and hole punching between peers
• create encrypted peer-to-peer messaging between browsers and servers
• build a blockchain or DHT network layer in Go
• multiplex multiple protocols over a single peer connection

When to choose

• you are building decentralized or peer-to-peer applications in Go, Rust, or JavaScript
• you need cross-language interoperability via a shared protocol specification
• you need built-in NAT traversal, encrypted connections, and multiple transports
• you want a battle-tested stack used by IPFS, Ethereum, and Filecoin

When to avoid

• you only need simple client-server HTTP communication
• you want a zero-configuration networking solution with minimal concepts to learn
• your project requires a small dependency footprint, as libp2p is a large modular stack
• you need a stable API with long-term guarantees, since libp2p's APIs evolve with the specs
