Cosmos Hub (ATOM)

About Cosmos Hub

Cosmos Hub is a blockchain network consisting of independent, parallel blockchains called zones, each powered by Byzantine fault-tolerant (BFT) consensus protocols like Tendermint. Some zones act as hubs, enabling interoperability between multiple zones through a shared hub. The architecture uses classic BFT and Proof-of-Stake algorithms instead of Proof-of-Work. Cosmos can interoperate with multiple other applications and cryptocurrencies, allowing users to create new zones and plug any blockchain system into the Cosmos hub to pass tokens back and forth without an intermediary. The native token, ATOM, serves three purposes: spam prevention (paying fees proportional to computation), staking (bonding to earn block rewards and provide economic security), and governance (voting on proposals).

• Cosmos uses classic Byzantine fault-tolerant (BFT) consensus protocols like Tendermint, not Proof-of-Work.
• The Cosmos network consists of independent, parallel blockchains called zones that can interoperate through a shared hub.
• ATOM tokens are used for spam prevention, staking, and governance on the Cosmos Hub.
• The economic security of the Cosmos Hub is directly tied to the amount of ATOM staked.
• Cosmos can interoperate with multiple other applications and cryptocurrencies, a feature other blockchains cannot do well.
