The ATOM token is the native token of the Cosmos network and plays an important role in achieving blockchain interoperability and governance rights. Cosmos is a decentralized blockchain ecosystem designed to facilitate interconnectivity among multiple independent blockchains.
Cosmos also utilizes a blockchain message communication protocol called Inter-Blockchain Communication (IBC), which enables cross-chain communication between different blockchains. The Cosmos SDK is a modular framework for building application-specific, interoperable blockchains, which further reduces the development cycle for third-party developers. It allows developers to port any existing blockchain code repository onto Golang, while Ethermint specifically targets the Ethereum network. All existing tools such as Truffle and Metamask are compatible with Ethermint, requiring no additional work for smart contract portability.
Cosmos was founded in 2014 by Jae Kwon and Ethan Buchman. Kwon is the founder of Tendermint and Buchman is the founder of the Cosmos SDK. In March 2022, the total locked-in value (TVL) of the Cosmos ecosystem exceeded $10 billion.
