    Cosmos SDK

    Cosmos SDK

    A Framework for Building High Value Public Blockchains

    ...Cosmos SDK is used to build Gaia, the first implementation of the Cosmos Hub. The Cosmos SDK has mostly stabilized, but we are still making some breaking changes. The Cosmos SDK is an open-source framework for building multi-asset public Proof-of-Stake (PoS) blockchains, like the Cosmos Hub, as well as permission Proof-of-Authority (PoA) blockchains. Blockchains built with the Cosmos SDK are generally referred to as application-specific blockchains. The goal of the Cosmos SDK is to allow developers to easily create custom blockchains from scratch that can natively interoperate with other blockchains.
