With ZKP age verification, services will not be able to track you without help from the CA. The CA will not be able to track you without help from the services. Both will contain the necessary information in their databases that when combined deanonymize you. The CA is the central authority/certificate authority.

So you should assume the government can track you, because you should assume both will be streaming those identifiers to it.

Yes, there is one party that can track you, which in some countries is still slightly trusted.

Ideally, no age verification would be required or proposed. However, if it is, this implementation should be the base minimum, should it not?

This is a gazillion percent better than a foreign corporation being in charge, isn't it?

This isn't correct. With ZKP-based systems even the CA can't track you. That's the "zero-knowledge" part.

but how is that possible? that even the CA cannot track you?
