Cosmos is a decentralized network of independent blockchains that aims to create an "Internet of Blockchains," allowing them to communicate and share data seamlessly. Launched by the Tendermint team in 2019, Cosmos seeks to address the fragmentation of blockchain networks by providing an ecosystem where different chains can coexist and interact without sacrificing sovereignty. This interoperability is enabled by the Cosmos SDK, a modular framework that simplifies blockchain development, and the Inter-Blockchain Communication (IBC) protocol, which facilitates secure and scalable communication between chains.
The native cryptocurrency of the Cosmos network is ATOM, which plays a vital role in maintaining network security through a proof-of-stake (PoS) consensus mechanism. ATOM holders can stake their tokens to participate in network governance and validate transactions, earning rewards for their contributions. Cosmos has become popular for projects and developers looking for flexible and interoperable blockchain solutions, as it provides tools for creating application-specific blockchains with custom rules and purposes.
