The Cosmos SDK is a framework for building blockchain applications. [Tendermint Core (BFT Consensus)](https://github.com/tendermint/tendermint) and the Cosmos SDK are written in the Golang programming language. Cosmos SDK is used to build [Gaia](https://github.com/cosmos/gaia), the first implementation of the Cosmos Hub.
**WARNING**: The Cosmos SDK has mostly stabilized, but we are still making some
To learn how the Cosmos SDK works from a high-level perspective, see the Cosmos SDK [High-Level Intro](./docs/intro/overview.md).
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](./docs/).

## Tools and Frameworks
The Cosmos ecosystem is vast. We will only make a few notable mentions here.
+ [Tools](https://v1.cosmos.network/tools): notable frameworks and modules.
+ [CosmJS](https://github.com/cosmos/cosmjs): the Swiss Army knife to power JavaScript based client solutions.
### Cosmos Hub Mainnet
The Cosmos Hub application, `gaia`, has moved to 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 moved to its own [cosmos/ibc-go repository](https://github.com/cosmos/ibc-go). Go there to build and integrate with the IBC module.
### Starport
Starport is the all-in-one platform to build, launch, and maintain any crypto application on a sovereign and secured blockchain. If you are building a new app or a new module, use [Starport](https://github.com/tendermint/starport) to get started and speed up development.
## 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.
