Cosmos SDK
The Cosmos SDK is a framework for building blockchain applications. CometBFT (BFT Consensus) and the Cosmos SDK are written in the Go programming language. Cosmos SDK is used to build 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 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.
If you want to get started quickly and learn how to build on top of Cosmos SDK, visit Cosmos SDK Tutorials. 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.
Contributing
See CONTRIBUTING.md for details on how to contribute and participate in our dev calls. If you want to follow the updates or learn more about the latest design then join our Discord.
Tools and Frameworks
The Cosmos ecosystem is vast. 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. 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. Go there to build and integrate with the IBC module.
Disambiguation
This Cosmos SDK project is not related to the 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.
