    Zero knowledge proof. Trusted issuer issues proof of birthdays. User submits proof of minimum age without disclosing additional information.

      That would require you to disclose proof of your real-life identity to some dubious company for the purpose of unlocking porn. Definitely not privacy-preserving.

        The company you disclose your age and online reference to doesn’t need to know how their confirmation will be used. It could be an entity already knowledgeable (DVLA, IRS).

        But yes, if porn is the only use case then this method is self incriminating.

          That is precisely the problem. It will mostly or only be used for porn.

            Not really. Most social media involves some rudimentary age verification, even though their age threshold is lower. Same goes for banking and interacting with government sites. Far from the only ones.
