I see some comments talking about how proof of personhood is necessary, however the way that Worldcoin does it leaves a gap between the cryptographic proof keys and the identity. TL;DR there isn’t a way to connect biometrics to key pairs unless the key pairs are generated using biometrics (very insecure) or the orb attests that they are unique from a hardware signature to Worldcoin (which means Worldcoin is a central issuer of identity and controls global identity).
