Tendermint

Byzantine-Fault Tolerant State Machine Replication. Or Blockchain for short.

version API Reference Go version riot.im license

Branch Tests Coverage
master CircleCI codecov
develop CircleCI codecov

Tendermint Core is Byzantine Fault Tolerant (BFT) middleware that takes a state transition machine - written in any programming language - and securely replicates it on many machines.

For protocol details, see the specification.

For detailed analysis of the consensus protocol, including safety and liveness proofs, see our recent paper, "The latest gossip on BFT consensus".

A Note on Production Readiness

While Tendermint is being used in production in private, permissioned environments, we are still working actively to harden and audit it in preparation for use in public blockchains, such as the Cosmos Network. We are also still making breaking changes to the protocol and the APIs. Thus, we tag the releases as alpha software.

In any case, if you intend to run Tendermint in production, please contact us and join the chat.

Security

To report a security vulnerability, see our bug bounty program

For examples of the kinds of bugs we're looking for, see SECURITY.md

Minimum requirements

Requirement Notes
Go version Go1.10 or higher

Documentation

Complete documentation can be found on the website.

Install

Quick Start

Resources

Tendermint Core

For details about the blockchain data structures and the p2p protocols, see the the Tendermint specification.

For details on using the software, see the documentation which is also hosted at: https://tendermint.com/docs/

Tools

Benchmarking and monitoring is provided by tm-bench and tm-monitor, respectively. Their code is found here and these binaries need to be built seperately. Additional documentation is found here.

Sub-projects

  • Amino, a reflection-based improvement on proto3
  • IAVL, Merkleized IAVL+ Tree implementation

Versioning

SemVer

Tendermint uses SemVer to determine when and how the version changes. According to SemVer, anything in the public API can change at any time before version 1.0.0

To provide some stability to Tendermint users in these 0.X.X days, the MINOR version is used to signal breaking changes across a subset of the total public API. This subset includes all interfaces exposed to other processes (cli, rpc, p2p, etc.), but does not include the in-process Go APIs.

That said, breaking changes in the following packages will be documented in the CHANGELOG even if they don't lead to MINOR version bumps:

  • types
  • rpc/client
  • config
  • node
  • libs
    • bech32
    • common
    • db
    • errors
    • log

Exported objects in these packages that are not covered by the versioning scheme are explicitly marked by // UNSTABLE in their go doc comment and may change at any time without notice. Functions, types, and values in any other package may also change at any time.

Upgrades

In an effort to avoid accumulating technical debt prior to 1.0.0, we do not guarantee that breaking changes (ie. bumps in the MINOR version) will work with existing tendermint blockchains. In these cases you will have to start a new blockchain, or write something custom to get the old data into the new chain.

However, any bump in the PATCH version should be compatible with existing histories (if not please open an issue).

For more information on upgrading, see here
