The Cosmos Hub is a public Proof-of-Stake chain that uses ATOM as its native staking token. It is the first blockchain launched in the Cosmos Network and developed using the cosmos-sdk development framework and ibc-go. Cosmos hub is also the first security aggregation platform that leverages the interchain-security protocol (ICS-28) to facilitate the launch of cosmos-sdk blockchain projects.
Interchain security features deployed on the Cosmos Hub blockchain allow anyone to launch a blockchain using a subset, or even the entire validator set of the Cosmos Hub blockchain.
  • gaia is the name of the Cosmos SDK application for the Cosmos Hub.
  • gaiad is the daemon and command-line interface (CLI) that operates the gaia blockchain application.
