The Cosmos SDK is a framework for building blockchain applications. Tendermint Core (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.
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.
See CONTRIBUTING.md for details on how to contribute and participate in our dev calls.
