Mainnet checklist

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.

Systemd

Now that you have Nimbus up and running, we recommend setting up a systemd service with an autorestart on boot (should you experience an unexpected power outage, this will ensure your validator restarts correctly).

Systemd will also ensure your validator keeps running when you exit your ssh session (Ctrl-C) and/or switch off your laptop.

For the details on how to do this, see this page.

VPN

To avoid exposing your validator identity (IP address) to the network, we recommend using a trustworthy VPN such as protonmail. While it may result in the occasional missed attestation, we believe the tradeoff is worth it.

Ethereum Foundation's Checklist

Ad a final check, we recommend you also go through the EF'S staker checklist.
