# CometBFT

Welcome to the CometBFT documentation!

CometBFT is a blockchain application platform; it provides the equivalent
of a web-server, database, and supporting libraries for blockchain applications
written in any programming language. Like a web-server serving web applications,
CometBFT serves blockchain applications.

More formally, CometBFT performs Byzantine Fault Tolerant (BFT)
State Machine Replication (SMR) for arbitrary deterministic, finite state machines.
For more background, see [What is CometBFT?](/cometbft/v0.37/docs/introduction/what-is-cometbft).

To get started quickly with an example application, see the [quick start guide](/cometbft/v0.37/docs/guides/quick-start).

To learn about application development on CometBFT, see the [Application Blockchain Interface](/cometbft/v0.37/spec/abci/README).

For more details on using CometBFT, see the respective documentation for
[CometBFT internals](/cometbft/v0.37/docs/core/README), [benchmarking and monitoring](/cometbft/v0.37/docs/tools/README), and [network deployments](/cometbft/v0.37/docs/networks/README).

## Contribute

To recommend a change to the documentation, please submit a PR. Each major
release's documentation is housed on the corresponding release branch, e.g. for
the v0.34 release series, the documentation is housed on the `v0.34.x` branch.

When submitting changes that affect all releases, please start by submitting a
PR to the docs on `main` - this will be backported to the relevant release
branches. If a change is exclusively relevant to a specific release, please
target that release branch with your PR.

Changes to the documentation will be reviewed by the team and, if accepted and
merged, published to (/cometbft) for the respective version(s).

The build process for the documentation is housed in the [Cosmos docs repository](https://github.com/cosmos/docs/tree/main/cometbft).
