Adding or Changing Graffiti flag

Setup your graffiti, a custom message included in blocks your validator successfully proposes, and earn an early beacon chain validator POAP token. Generate your POAP string by supplying an Ethereum 1.0 address here.

Change the --graffiti value on ExecStart line. Save your file.

sudo nano /etc/systemd/system/validator.service

Reload the updated unit file and restart the validator process for your graffiti to take effect.

sudo systemctl daemon-reload
sudo systemctl restart validator
