If I understand them correctly, the proposals are quite different. The US is effectively requiring the implementation of a third party verification service at computer set-up. The EUs approach validates an existing cryptographic identity that says you are over a certain age, without exposing your identification.

Please correct me if I am wrong, this is what I read here.

Do you expect the EU to insist on a different solution once the US solution is in-place in all US-based operating systems?
