    PGP isn’t tied to a specific person though.

    I’m starting to come around to the idea of gov’t backed crypto ID, but I am very worried about the potential abuse of that system

        Yes, but it’s not Sybil resistant. Anyone can make as many PGP Keys as they want.

        What is really needed is the ability to sign messages proving:

        • that I am a specific person (“I am John Smith”)
        • that I am a unique person without revealing my ID (“I only have one account here”)
        • attributes about me without revealing my ID (“I am 18+”, “I am a French Citizen”, etc)

        This is all possible with ZK cryptography today if you have a trusted data source for the key storage. Governments might be able to set something like this up, but that comes with a lot of privacy concerns. There are other projects like WorldCoin, Idena, and Proof of Humanity that attempt to do this in a decentralized way, but they’ve all had issues with adoption
