The Cosmos Hub is the first of an exploding number of interconnected blockchains that comprise the Cosmos Network.

🤔 Why should you be interested in the Cosmos Hub

The Cosmos Hub is built using the Cosmos SDK and compiled to a binary called gaiad (Gaia Daemon). The Cosmos Hub and other fully sovereign Cosmos SDK blockchains interact with one another using a protocol called IBC that enables Inter-Blockchain Communication. In order to understand what the Cosmos Hub is you can read this introductory explanation.

For an overview of the Interchain Stack (the Cosmos SDK, IBC, etc.), as well as examples and exercises to help developers get a quick start, please visit tutorials.cosmos.network.

Additional resources

For node operators: If you're interested in running a node on the current Cosmos Hub, check out the docs to Join the Cosmos Hub Mainnet.

For validators: If you want to participate and help secure the Cosmos Hub and its consumer chains, consider becoming a validator. Information on what a validator is and how to participate as one can be found at the Validator FAQ. If you're running a validator node on the Cosmos Hub, reach out to a Janitor on the Cosmos Developers Discord to join the #cosmos-hub-validators-verified channel.

For delegators: If you want to secure the Cosmos Hub without running a validator, you can consider becoming a delegator. Information on what a delegator is and how to participate as one can be found at the Delegator FAQ.

Testnet

To participate in or utilize the current Cosmos Hub testnet, take a look at the cosmos/testnets repository.

Archives & Genesis

In the Cosmos Network, chain IDs have a revision number that is incremented on a hard-fork, i.e., when the chain restarts from a new genesis state. Mainnet is currently running as cosmoshub-4. If you are looking for historical genesis files and other data cosmos/mainnet is an excellent resource. Snapshots are also available at cosmos.quicksync.io.
