You can do that without the blockchain using something like Estonia's 20 year old digital signature scheme. All you need is a private key, not distributed consensus 'not your keys not your porn' silliness. [1]

A blockchain doesn't help here because your personal identity is not a bearer token. If someone has your private keys they do not become you. And if they do have your private keys you better have some authority to revoke them.

That's really cool, I don't know how I'd never heard about this before.

And yes, just in case it wasn't clear, I'm not advocating blockchain here, I have no stake in that stuff or any real understanding of it. But I do like the "digital signatures/attestations" idea. Thanks for sharing the wiki link, I'll have to do some more reading on Estonia's system.
