How difficult would it be to add further anonymization? Let's say I want to prevent the bike shop from building a usage profile on the basis of the age check (e.g. because I'm buying booze). Would I just need to get more chains from Alice, or is there an easy way to integrate e.g. group signatures into the scheme?
I think the way to go would be for Alice to give you lots of commitments. They are computationally light-weight to generate anyway.
That would at least be a good and also simple solution. Maybe there is a perfect solution, but then I dont know it.
