* Website gives person a unique code to broadcast on the blockchain to prove they have control over that identity
* 'Approved' services claim things publically about identities (eg age, allowed to drive) which others can use to verify claims
What I don't get is:
* how you know which 'approved' services to trust in the first place
* why you'd want all of that information public
* how it'd fix the original issue
The other issue is that none of this is necessary. If I want to prove to Person X that Gov Y says that I have property Z, why can't I just present a cryptographically signed certificate saying I have property X. You could even have a similar revocation list as CA.
