While reading this, I was interested in the "double-blind tokenised approach" of age confirmation that guarantees privacy. I think it is described here: https://avpassociation.com/wp-content/uploads/2024/08/Specification-Version-1.0.pdf https://avpassociation.com/wp-content/uploads/2024/08/Specif... It seems quite a good idea to me. It would be great if that was implemented, instead of 'dumb' requirement for everyone to upload ID to check for age.

I completely agree, it is absolutely not necessary to provide ID in order to assert some property securely and anonymously. The cryptographer Jan Camenisch has done a lot of good work in this area [1], including IdentityMixer and Direct Anonymous Attestation. The scheme you link above seems to provide at least pseudonymous age proof, and does not allow the verifier to track what you visit. It's not clear to me whether it prevents linkability (i.e. although a site doesnt know who you are, they could link each time the same pseudonymous visitor connects).
