## Tendermint
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 background, see the [the docs](https://docs.tendermint.com/master/introduction/#quick-start).
To get started developing applications, see the [application developers guide](https://docs.tendermint.com/master/introduction/quick-start.html).
## How to use this image
### Start one instance of the Tendermint core with the `kvstore` app
A quick example of a built-in app and Tendermint core in one container.
```sh
docker run -it --rm -v "/tmp:/tendermint" tendermint/tendermint init
docker run -it --rm -v "/tmp:/tendermint" tendermint/tendermint node --proxy_app=kvstore
```
## Local cluster
To run a 4-node network, see the `Makefile` in the root of [the repo](https://github.com/tendermint/tendermint/blob/master/Makefile) and run:
```sh
make build-linux
make build-docker-localnode
make localnet-start
```
Note that this will build and use a different image than the ones provided here.
