description Cosmos SDK Overview

The Cosmos SDK is a modular framework for building application-specific blockchains. It provides tools and libraries to simplify the creation of custom chains that can interoperate with other blockchains via the Inter-Blockchain Communication (IBC) protocol. Its focus on sovereignty and interoperability makes it ideal for creating specialized blockchain ecosystems.

help Cosmos SDK FAQ

What is the Cosmos SDK used for?

The Cosmos SDK is a Go framework for building application-specific blockchains. It is used in the Cosmos ecosystem by chains such as Cosmos Hub and Osmosis.

How does Cosmos SDK relate to IBC?

Cosmos SDK chains can use the Inter-Blockchain Communication protocol, known as IBC, to transfer data and tokens between compatible chains. IBC is one of the main reasons Cosmos is described as an internet of blockchains.

What consensus engine does Cosmos SDK usually pair with?

Cosmos SDK chains commonly pair with CometBFT, the successor name for Tendermint Core. The SDK handles application logic while CometBFT handles consensus and networking.

What modules come with the Cosmos SDK?

The SDK includes modules for common blockchain functions such as bank transfers, staking, governance, slashing, and distribution. Developers can use those modules as building blocks instead of writing every chain feature from scratch.
