The Cosmos SDK is an open-source modular framework for building application-specific blockchains in the Cosmos ecosystem. It provides composable modules for accounts, staking, governance, and token management, and integrates with the Tendermint BFT consensus engine to enable sovereign, interoperable chains connected via the Inter-Blockchain Communication protocol.
Semantic Classification
Content
- The Cosmos SDK is a framework that lets developers build custom blockchains by combining modules for features such as accounts, staking, and governance. Applications built with it run on top of a consensus engine, commonly Tendermint.
- Chains built with the SDK can connect to others through the Inter-Blockchain Communication protocol, allowing tokens and data to move between them. The modular design lets developers include only the functionality their application needs.
