@ansuz@gts.cryptography.dog @kbal@fedia.io @mullvadnet@mastodon.online The credential cannot be transferred because it's attached to a guaranteed unique ID that is the entity the credential is for and this with the values in the credential are cryptographically signed by the entity that validated the actual content or whatever. Any attempt to "transfer" is going to invalidate the signature. It can be copied around quite freely though. Hence the ZKP part meant to hide the actual birthday. Right now I'm not really convinced it does so.
