Gaia is the first implementation of the Cosmos Hub, built using the Cosmos SDK. Gaia and other fully sovereign Cosmos SDK blockchains interact with one another using a protocol called IBC that enables Inter-Blockchain Communication.
Check out contributing.md for our guidelines & policies for how we develop the Cosmos Hub. Thank you to all those who have contributed!
Documentation for the Cosmos Hub lives at hub.cosmos.network.

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-3 are available here.
If you are looking for historical genesis files and other data
cosmos/mainnet is an excellent resource.
