Central repository for work on libp2p

This repository is the central place for Rust development of the libp2p spec.

Getting started

• Main documentation can be found on https://docs.rs/libp2p.

• The examples folder contains small binaries showcasing the many protocols in this repository.

• For security related issues please file a private security vulnerability report . Please do not file a public issue on GitHub.

• To report bugs, suggest improvements or request new features please open a GitHub issue on this repository.

• For rust-libp2p specific questions please use the GitHub Discussions forum https://github.com/libp2p/rust-libp2p/discussions.

• For discussions and questions related to multiple libp2p implementations please use the libp2p Discourse forum https://discuss.libp2p.io.

• For synchronous discussions join the open rust-libp2p maintainer calls or the biweekly libp2p community calls.

Repository Structure

The main components of this repository are structured as follows:

• core/: The implementation of libp2p-core with its Transport and StreamMuxer API on which almost all other crates depend.

• transports/: Implementations of transport protocols (e.g. TCP) and protocol upgrades (e.g. for authenticated encryption, compression, ...) based on the libp2p-core Transport API.

• muxers/: Implementations of the StreamMuxer interface of libp2p-core, e.g. (sub)stream multiplexing protocols on top of (typically TCP) connections. Multiplexing protocols are (mandatory) Transport upgrades.

• swarm/: The implementation of libp2p-swarm building on libp2p-core with the central interfaces NetworkBehaviour and ConnectionHandler used to implement application protocols (see protocols/).

• protocols/: Implementations of application protocols based on the libp2p-swarm APIs.

• misc/: Utility libraries.

• libp2p/examples/: Worked examples of built-in application protocols (see protocols/) with common Transport configurations.

Community Guidelines

The libp2p project operates under the IPFS Code of Conduct.

tl;dr

• Be respectful.
• We're here to help: abuse@ipfs.io
• Abusive behavior is never tolerated.
• Violations of this code may result in swift and permanent expulsion from the IPFS [and libp2p] community.
• "Too long, didn't read" is not a valid excuse for not knowing what is in this document.
