  • Introduction

    The Cosmos Network is a decentralized network of independent, scalable, and interoperable blockchains, creating the foundation for a new token economy. Before the Cosmos Network, blockchains were siloed and unable to communicate with each other. They were hard to build and could only handle a small number of transactions per second. Cosmos solves some of the hardest blockchain problems of scalability, usability and interoperability.

  • About The Project

    Cosmos is a decentralized network of independent parallel blockchains, each powered by BFT consensus algorithms like Tendermint consensus.

    The Cosmos SDK is a developer-friendly, modular framework, each powered by a Byzantine Fault-Tolerant consensus algorithm such as Tendermint BFT, allowing developers to fully customize their decentralized applications and focus on business logic. In other words, Cosmos is an ecosystem of blockchains that can scale and interoperate with each other. Before Cosmos, blockchains were siloed and unable to communicate with each other. They were hard to build and could only handle a small amount of transactions per second. Cosmos solves these problems with a new technical vision.

    The vision of Cosmos is to make it easy for developers to build blockchains and break the barriers between blockchains by allowing them to transact with each other. The end goal is to create an Internet of Blockchains, a network of blockchains able to communicate with each other in a decentralized way. With Cosmos, blockchains can maintain sovereignty, process transactions quickly and communicate with other blockchains in the ecosystem, making it optimal for a variety of use cases.

    This vision is achieved through a set of open source tools like Tendermint, the Cosmos SDK and IBC designed to let people build custom, secure, scalable and interoperable blockchain applications quickly. Note that Cosmos is an open source community project initially built by the Tendermint team. Everyone is welcome to build additional tools to enrich the greater developer ecosystem.
