I'm not sure that it would be too hard technically... basically, auth+social-network. Basically Facebook auth without the rest of facebook, adding attestation.
IE: you use this network as your auth provider, you get the user's real name, handle, network id as well as the id's (only id's not extra info) of first-third level connections.
The user is incentivized to connect (only) people that they know in person, and this forms a layer of trust. Downstream reports can break a branch or have network effect upstream. By connecting an account to another account, you attest that "this is a real person, that I have met in real life." Using a bot for anything associate with the account is forbidden, with exception to explicit API access to downstream services defined by those services.
I think it could work, but you'd have to charge a modest, but not overbearing fee to use the auth provider... say $100/site/year for an app to use this for user authentication.
I don't think the main challenge is building this system, the main challenge is getting enough people using it to make it worthwhile.
Personally I think it should be a government provided service, not something with a sign up fee. There's actually no point at all in building this if people have to pay to use it, because they won't
Which government? Will they interoperate with foreign governments?
My point was to create something outside a specific government, with very limited information... that would require a fee or some kind of funding.
I don't think I'd trust the US/China or other bodies to trust each other for such a use case.
> Will they interoperate with foreign governments?
Ideally, yes
But you're right, this isn't likely to happen in real life and I'm just being wishful. Instead we're going to get the much shittier capitalist version of this where every company and government spies on us and we have no expectation of privacy online at all
