Byzantine-Fault Tolerant State Machines. Or Blockchain, for short.

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".

Releases

Note: Please, do not depend on master as your production branch, use releases instead.

Tendermint is being used in production in both private and public environments, most notably the blockchains of the Cosmos Network. However, we are still making breaking changes to the protocol and the APIs and have not yet released v1.0. See below for more details about versioning.

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

Versioning

Semantic Versioning

Tendermint uses Semantic Versioning 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:

  • crypto
  • config
  • libs
    • bech32
    • bits
    • bytes
    • json
    • log
    • math
    • net
    • os
    • protoio
    • rand
    • sync
    • strings
    • service
  • node
  • rpc/client
  • types

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 UPGRADING.md.

Supported Versions

Because we are a small core team, we only ship patch updates, including security updates, to the most recent minor release and the second-most recent minor release. Consequently, we strongly recommend keeping Tendermint up-to-date. Upgrading instructions can be found in UPGRADING.md.
