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

NOTE: This is alpha software. Please contact us if you intend to run it in production.
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 more information, from introduction to installation and application development, Read The Docs.
For protocol details, see the specification.
Minimum requirements
| Requirement | Notes |
|---|---|
| Go version | Go1.9 or higher |
Install
To download pre-built binaries, see our downloads page.
To install from source, you should be able to:
go get -u github.com/tendermint/tendermint/cmd/tendermint
For more details (or if it fails), read the docs.

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.), as well as parts of the following packages:
- types
- rpc/client
- config
- node
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.
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).
Code of Conduct
Please read, understand and adhere to our code of conduct.
