Is it just me or does Worldcoin just seem like a massive ploy to get one's hands on a ton of biometric data? Scan your eyes and get $20 in funny money that may or may not be redeemable later. The coin will crash and burn like all the others leaving Sam with a treasure trove of biometrics data to do whatever he wants with.
I may be wrong, but isn’t Worldcoin using zero knowledge proofs in their system? It would mean that nobody has access to the private data behind them - not even WC.
No, it wouldn't mean that. It would only mean that entities who verify the zero knowledge proofs do not learn anything about the data except that it satisfies the proved property.
