🤔 — 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.

🗄️ — Archives & Genesis


With each version of the Cosmos Hub, the chain is restarted from a new Genesis state. Mainnet is currently running as cosmoshub-4. Archives of the state of cosmoshub-1, cosmoshub-2, and cosmoshub-3 are available here.

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.
