Sam Altman’s World project has launched in the U.S. It scans users’ irises in exchange for crypto, raising fresh concerns about privacy, biometric data and AI-linked identity systems.

The eyeball-scanning crypto play had originally stayed out of the U.S. market amid a more uncertain regulatory regime.

Altman co-founded "World" in 2019 — known as Worldcoin until last year — to create a global identity verification system.
