I looked at the technology used by the EU age verification.
You prove your age to the app by scanning the NFC in your passport. No government servers exist.
When a site requests your age, you return only a “yes I’m older than 18”, proven by your passport. Not your age, just that you’re older.
I think it preserves privacy pretty well.
I don’t think that it will protect children, but I do think that it preserves privacy.
