Cosmos Hub (Gaia)

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.

⚡ — Documentation & Introduction

You can find an introduction to the Cosmos Hub and how to use the gaiad binary as a delegator, validator or node operator as well as how governance on the Cosmos Hub works in the documentation.

👥 — Testnet

To participate in or utilize the current Cosmos Hub testnet that upgrades cosmoshub-4 from gaia v5.0.x to gaia v6.0.x, take a look at the vega-testnet repository. This testnet is for the Vega Upgrade expected in Q4 2021. For future upgrades of the Cosmos Hub take a look at the roadmap.

🗄️ — 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.
