There's a few new proof of human systems out there. For each of these you have a private key and the service attests that "the holder of this key is a human".

There's a few new proof of human systems out there. For each of these you have a private key and the service attests that "the holder of this key is a human". Then when you sign up to a service you can create a ZK proof that this service has said you're a human and that you haven't created another account before. This allows for anonymous registration while also proving you're not a bot. The two biggest services for this are: - Worldcoin - scan your eye in an orb and it attests you're human. This is integrated with Reddit and Discord already. - Gitcoin Passport - connect it to your social media accounts, proof of humanity services etc and it gives you a humanity point score.
