Cosmos SDK
The Cosmos SDK is a framework for building blockchain applications. Tendermint Core (BFT Consensus) and the Cosmos SDK are written in the Golang programming language. Cosmos SDK is used to build Gaia, the first implementation of the Cosmos Hub.
WARNING: The Cosmos SDK has mostly stabilized, but we are still making some breaking changes.
Note: Requires Go 1.17+
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 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. We will only make a few notable mentions here.
- Tools: notable frameworks and modules.
- 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. 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. 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 to get started and speed up development.
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.

unknownproto
unknownproto implements functionality to "type check" protobuf serialized byte sequences against an expected proto.Message to report: a) Unknown fields in the stream -- this is indicative of mismatched services, perhaps a malicious actor b) Mismatched wire types for a field -- this is indicative of mismatched services Its API signature is similar to proto.Unmarshal([]byte, proto.Message) in the strict case if err := RejectUnknownFieldsStrict(protoBlob, protoMessage, false); err != nil { // Handle the error.
