Latest software

Please check that you are running the latest stable Nimbus software release.

Note: If you are setting up your client before launch, it is your responsibility to check for any new software releases in the run up to launch. At the minimum you should check the release page weekly.

More than 20 peers

Please check that your node has at least 15 peers. See the footer at the bottom of the terminal window for your peer count.

Validator attached

Please check that your validator is attached to your node.


To avoid exposing your validator identity to the network, we recommend you use a trustworthy VPN such as protonmail.. This help reduce the risk of revealing your IP address to the network.
