Cosmos SDK
The Cosmos-SDK is a framework for building blockchain applications in Golang.
It is being used to build Gaia, the first implementation of the Cosmos Hub.
WARNING: The SDK has mostly stabilized, but we are still making some breaking changes.
Note: Requires Go 1.15+
Quick Start
To learn how the SDK works from a high-level perspective, go to the SDK Intro.
If you want to get started quickly and learn how to build on top of the SDK, please follow the SDK Application Tutorial. You can also fork the tutorial's repository to get started building your own Cosmos SDK application.
For more, please go to the Cosmos SDK Docs.
Cosmos Hub Mainnet
The Cosmos Hub application, gaia, has moved to its own repository. Go there to join the Cosmos Hub mainnet and more.
Starport
If you are starting a new app or a new module you can use Starport to help you get started and speed up development. If you have any questions or find a bug, feel free to open an issue in the repo.
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.
