cat ~/$WORKSPACE/keys/public-keys.yaml

• OWNER KEY: the first wallet public key. open your Petra wallet, then click Settings -> Credentials

• Next, click on VALIDATE NODE. If your node passes healthcheck, you will be prompted to complete the identity verification process.

The Aptos team will perform a node health check on your validator, using the Node Health Checker. When Aptos confirms that your node is healthy, you will be asked to complete the KYC process.
