You’re doing it now with this note and every other you create. 😀 Your identification is what you’ve chosen to add to your profile, but that could be blank, of course.

Let’s just say hypothetically that corporate tech is forced to age verify. Could it be helpful with that?
Public-private key pairs enable cryptographic verification that the holder/owner of the private key created the artifact (text, image, note) in question. That’s all, but it’s immensely powerful.
As for attributes or credentials, we then get into things like Decentralized ID (DID) and so-called Verified Credentials. These become considerably more complex. Some are bullish on these schemes, others not so much.
