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.

- agentwiggles 4y agoThat'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.
