## Teams Dev Calls

The Cosmos SDK has many stakeholders contributing and shaping the project. Regen Network Development leads the Cosmos SDK R&D, and welcomes long-term contributors and additional maintainers from other projects. We use self-organizing principles to coordinate and collaborate across organizations in structured "Working Groups" that focus on specific problem domains or architectural components of the Cosmos SDK.

The developers are organized in working groups which are listed on a ["Working Groups & Arch Process" Github Issue](https://github.com/cosmos/cosmos-sdk/issues/9058) (pinned at the top of the [issues list](https://github.com/cosmos/cosmos-sdk/issues)).

The important development announcements are shared on [Discord](https://discord.com/invite/cosmosnetwork) in the \#dev-announcements channel.

To synchronize we have few major meetings:
+ Architecture calls: bi-weekly on Fridays at 14:00 UTC (alternating with the grooming meeting below).
+ Grooming / Planning: bi-weekly on Fridays at 14:00 UTC (alternating with the architecture meeting above).
+ Cosmos Community SDK Development Call on the last Wednesday of every month at 17:00 UTC.
+ Cosmos Roadmap Prioritization every 4 weeks on Tuesday at 15:00 UTC (limited participation).

If you would like to join one of those calls, then please contact us on [Discord](https://discord.com/invite/cosmosnetwork) or reach out directly to Cory Levinson from Regen Network ([email protected]).


## Architecture Decision Records (ADR)

When proposing an architecture decision for the Cosmos SDK, please start by opening an [issue](https://github.com/cosmos/cosmos-sdk/issues/new/choose) or a [discussion](https://github.com/cosmos/cosmos-sdk/discussions/new) with a summary of the proposal. Once the proposal has been discussed and there is rough alignment on a high-level approach to the design, the [ADR creation process](https://github.com/cosmos/cosmos-sdk/blob/master/docs/architecture/PROCESS.md) can begin. We are following this process to ensure all involved parties are in agreement before any party begins coding the proposed implementation. If you would like to see examples of how these are written, please refer to the current [ADRs](https://github.com/cosmos/cosmos-sdk/tree/master/docs/architecture).

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
breaking changes.

**Note**: Requires [Go 1.17+](https://golang.org/dl/)

## Quick Start

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/).

## 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.

## 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.
