Over the past few years, what sounds like an episode of Black Mirror has been unfolding in real life: millions of people around the world have agreed to let metallic orbs scan their eyes in exchange for receiving a blockchain-based ID and a cryptocurrency called Worldcoin.

Coinbase, the largest crypto exchange in the US, has announced the possibility of listing Sam Altman's World Network (WLD).

At a buzzy event in San Francisco, World announced a series of Apple-like stores, a partnership with dating giant Match Group, and a new mini gadget to scan your eyeballs.
