README
Cosmos SDK
The Cosmos SDK is a framework for building blockchain applications. [CometBFT (BFT Consensus)](https://github.com/cometbft/cometbft) and the Cosmos SDK are written in the Go programming language. Cosmos SDK is used to build [Gaia](https://github.com/cosmos/gaia), the implementation of the Cosmos Hub.
**WARNING**: The Cosmos SDK has mostly stabilized, but we are still making some breaking changes.
**Note**: We advise to always use the latest maintained [Go](https://go.dev/dl) version for building Cosmos SDK applications.
## Quick Start
To learn how the Cosmos SDK works from a high-level perspective, see the Cosmos SDK [High-Level Intro](https://docs.cosmos.network/main/intro/overview).
If you want to get started quickly and learn how to build on top of Cosmos SDK, visit [Cosmos SDK Tutorials](https://tutorials.cosmos.network). You can also fork the tutorial's repository to get started building your own Cosmos SDK application.
For more information, see the [Cosmos SDK Documentation](https://docs.cosmos.network).
## Modules
The Cosmos SDK maintains a set of modules that can be included in your blockchain application. For more information
on modules, see our [introduction doc](./x/README.md).
## Contributing
See [CONTRIBUTING.md](./CONTRIBUTING.md) for details on how to contribute and participate in our [dev calls](./CONTRIBUTING.md#teams-dev-calls).
If you want to follow the updates or learn more about the latest design then join our [Discord](https://discord.com/invite/cosmosnetwork).
## Tools and Frameworks
The Cosmos ecosystem is vast.
[Awesome Cosmos](https://github.com/cosmos/awesome-cosmos) is a community-curated list of notable frameworks, modules and tools.
### Cosmos Hub Mainnet
The Cosmos Hub application, `gaia`, has its own [cosmos/gaia repository](https://github.com/cosmos/gaia). Go there to join the Cosmos Hub mainnet and more.
### Inter-Blockchain Communication (IBC)
The IBC module for the Cosmos SDK has its own [cosmos/ibc-go repository](https://github.com/cosmos/ibc-go). Go there to build and integrate with the IBC module.
## Disambiguation
This Cosmos SDK project is not related to the [React-Cosmos](https://github.com/react-cosmos/react-cosmos) project (yet). Many thanks to Evan Coury and Ovidiu (@skidding) for this Github organization name. As per our agreement, this disambiguation notice will stay here.
