Edward Snowden Slams Sam Altman's Worldcoin: 'Don't Catalogue Eyeballs'

That's orthogonal to the point. Here's the scenario:

1. User has a "fake" biometric A, generated via GAN or [1], that's cheap and easy to produce.

2. Suppose they can present A to any orb device, generating hash(A), which signs hash(A) using its built-in private key as usual.

As long as the user can generate a fake iris biometric scan accepted by an orb, no other part of the system needs to be compromised for this attack to work.

See my original post. It's pretty clear that process of initial distribution of tokens is not open. Volunteers are likely contributing lots of private data to the company to get their hands on orbs.
