* EDIT: 100% sure that it’s technically possible to have an endpoint anonymously verify age and a verification system to do so without knowing the endpoint requesting the verification, but unable to find technical explanation of how this might be done using existing technology; might be wrong, but believe it included a combination of differential privacy and zero knowledge proofs. Does anyone have a link to detailed explanation of how to implement such a system?
