Zero-Knowledge Proofs Aren’t Age Verification Silver Bullets The idea behind ZKPs is that you are issued a “token” that vouches for your age every time you log in, creating a constant link back to the entity that verified you. The issuer of the tokens these AV schemes rely on could track every time that credential is used, creating a dangerous trail of metadata on any user they wanted to target. The issuer itself could be pressured by authoritarian governments to remove a user’s access to a service, essentially removing that person’s access to the internet entirely. a centralized identity verification system creates a single point of failure that is extremely vulnerable to both cyberattack and authoritarian overreach. Personally I’m optimistic that tech like this can be used in positive ways, but imo they should be developed transparently (open source) and decentralized.
