Is it the following:
Issuer revokes the wallet of Alice and then publicly says “This ID is Alice btw” and then verifiers can check their lists to see whether any of their received signatures are revoked (in which case they must be Alice)
Yeah
I'm getting really really tired of the "crying wolf" crowd
Many Americans don't even have ID (and plenty of those are reluctant to the general concept of any kind of government ID), let alone any kind of digital ID. However, their governments are pushing frankly weird and absurd ID verification laws to businesses online. Meta seems to be bankrolling lobbying around these laws, so whatever their game is, it's probably very bad for normal people.
If you're coming from a place where the government tells companies they need to set up a system or hire private companies to verify users' ages without providing any kind of official mechanism themselves, leading to ridiculous hacks from cheap and incompetent "age verification" companies, I can understand why the European system seems absurd.
If the US is going to adopt their weird age verification laws, the least they could do is fork the European system already laid out for them. Put a little American flag on it, call it "America First Christian Age Truthness" or whatever the people in charge like, but at least keep the basic privacy properties intact.
