Description
libp2p is an open source networking library used by the world's most important distributed systems such as Ethereum, IPFS, Filecoin, Optimism and countless others. There are native implementations in Go, Rust, Javascript, C++, Nim, Java/Kotlin, Python, .Net, Swift and Zig. It is the simplest solution for global scale peer-to-peer networking and includes support for pub-sub message passing, distributed hash tables, NAT hole punching and browser-to-browser direct communication.
Features include:
- Use Several Transports: Use newer and faster transports like QUIC and WebRTC. At the same time, we support well-established transports like TCP, and support multiple hosts and connectivity conditions.
- Native Roaming: You get Native Roaming out of the box. Your app or service can be migrated between machines or move between networks without any configuration steps.
- Runtime Freedom: Simply assume connectivity, independent of the platform you are running your software on.
- Protocol Muxing: Reuse already established and secure connections with in-band protocol multiplexing.
- Work Offline: libp2p is capable of discovering other peers without resourcing to centralized registries, enabling apps to work disconnected from the backbone.
- Encrypted Connections: Ensure that no one can eavesdrop on user traffic by setting a crypto channel by default, protecting both bits and validating peer identities.
- Upgrade Without Compromises: Don't let past decisions hold your application back. Wire protocol versioning allows you to upgrade your service while still supporting older versions, no complicated setup necessary.
- Work In The Browser: Write your application to run in the browser and take advantage of the ultimate in cross platform environments and with zero user install.
- Good For High Latency Scenarios: Not all connections are equal. Make sure your app is using the best transport for its environment.
