Just because I were curious enough to check this out, from Wikipedia:
Worldcoin aims to provide a reliable way to authenticate humans online, to counter bots and fake virtual identities facilitated by artificial intelligence. Using a distribution mechanism for its cryptocurrency similar to UBI, Worldcoin attempts to incentivize users to join its network by getting their iris scanned using Worldcoin’s orb-shaped iris scanner.
Market share. If you look on the server side though, you find the total opposite.
