I was just researching this project, I found this is not new (of course I heard about it here) and in first glance, it seemed like some dystopian concept straight from an episode of black mirror, and in depth it seems like a cool concept of world citizenship.

However, I couldn't understand the project completely. There are weird devices which are scanning people's eyes to get a map of Iris (since it is also like the fingerprint and unique to people) and the scanner is being rewarded? So what will happen to the scanned person? Won't they be rewarded? It may seem hard to handle but there might be a solution to that.

Also there are publicly available Iris datasets (from medical centers or government offices which used Iris scan as a form of biometric authentication) and what happens if World Coin, specially being backed by Sam Altman (who has a history of using copyrighted material for OpenAI's model training) uses those and those people don't benefit from that?

These are my thoughts or questions. I am really curious to here about your thoughts on this.
