the same thing that prevents them from doing reuse right now: platform detection mechanisms. the difference is that right now the identity of the subject is known whereas with ZKP (nullifier approach) only the dirty token is known and where that token was used.
So....what exactly would platform detection mechanisms be basing their decisions off of that wouldn't defeat the entire privacy-preserving premise of ZKP?
multiple use of the same token on multiple accounts...?
tying multiple accounts and services together isn't ideal but its inarguably better than tying your real world identity to every single service.
Wait - so you're advocating for use of a persistent identifier tied to a person? How is that any different than what advertising networks do right now beyond giving them additional guaranteed information of your age bracket?
To clarify - it's not cryptographically necessary to present the same token for each and every transaction and serves to categorically defeat the entire privacy guarantee of ZKP.
It also makes it trivial to associate your ZKP token with your real identity.
