> That doesn't make sense, all IDs are already in a single government database. Kind of by definition in fact, for IDs to be useful they need to be emitted by a central authority with associated security and revokability guarantees.
Yes and those databases are decently protected. However for an "app" someone will do a web 4.0 or 6.0 bridge to access these databases. Maybe even vibe code it. That's what I'm worried about.
Hence the second paragraph in my comment. The app is client side and reads the physical ID.
Hmm how is it zero knowledge when you can be tracked to a single installation of an app? I thought zero knowledge means they ask a "trusted" 3rd party, i.e. the government. And that says yes/no, without passing any ID details on.
