 Congratulations, you should now be joining us - your node will start syncing with the current state of our beacon chain. Once you're in sync, you should also start proposing your own blocks and providing attestations - exciting! You are now among [Ethereum 2.0 Nimbus pioneers](https://gitcoin.co/kudos/1160/nimbus_pilot)!
