Have not looked into it yet but sounds a lot like a PKI based certificate style scheme: https://news.ycombinator.com/item?id=44723418

The verifier is the entity you hand your information to for verification, ie the CA. The extent of your interaction and linkage with them is mainly at point of verification and issuance.

It is however possible to trace a certificate to it's issuer, which on the surface sounds like a bad thing, but is in fact good if the goal is to provide privacy while ensuring accountability.

I mean in this case there is only one issuer, the Swiss state, so is that really a big deal? Ultimately the government is and should be the provider of identity.
