Worldcoin, co-founded by Altman in 2019, has been offering tokens of its own cryptocurrency to people around the world, in return for their consent to have their eyes scanned by an orb.

The scans are used as a form of identification as it seeks to create a reliable mechanism to distinguish between humans and machines as artificial intelligence becomes more advanced.
