It’s simply what it seems like: a basic method to utilize an Ethereum wallet that you own as an identifier throughout numerous services. If your very first idea is, “my name isn’t even attached to my ETH wallet,” that’s precisely the point: Using a cryptographic marker as an identity implies the user, not the identity service provider, has overall control over what info is connected with it. Eventually, you’ll have the ability to choose, for example, whether a specific service requires your name, evidence of your age, or a look of your ETH balance. You will not need to send out all that info to every service you utilize.
