tendermint-rs

Tendermint in Rust with TLA+ specifications.

Tendermint is a high-performance blockchain consensus engine for Byzantine fault tolerant applications written in any programming language.

Tendermint Core Compatibility

tendermint-rs has been tested for compatibility with Tendermint Core v0.34.21.

Requirements

Tested against the latest stable version of Rust. May work with older versions.

Semantic Versioning

We do our best to follow Semantic Versioning. However, as we are pre-v1.0.0, we use the MINOR version to refer to breaking changes and the PATCH version for features, improvements, and fixes.

We use the same version for all crates and release them collectively.

Documentation

See each component for the relevant documentation.

Libraries:

• tendermint - Tendermint data structures and serialization
• tendermint-abci - A lightweight, low-level framework for building Tendermint ABCI applications in Rust
• tendermint-light-client - Tendermint light client library for verifying signed headers and tracking validator set changes
• tendermint-light-client-detector - Library for detecting and reporting attacks against the Tendermint light client
• tendermint-light-client-cli - CLI for the light client, for verifying headers, detecting attacks and reporting them.
• tendermint-light-client-js - Low-level WASM interface for interacting with the Tendermint light client verification functionality
• tendermint-p2p - At present this primarily provides the ability to connect to Tendermint nodes via Tendermint's secret connection
• tendermint-proto - Protobuf data structures (generated using Prost) for wire-level interaction with Tendermint
• tendermint-rpc - Tendermint RPC client and response types

Releases

Release tags can be found on GitHub.

Crates are released on crates.io.
