About World
World is a proof-of-humanity project that uses iris scans to verify that a user is a real person. It was previously called Worldcoin, and DII describes it as co-founded by Sam Altman.
The project renamed itself from Worldcoin to World in October 2024. At that point it also showed a new version of its iris-scanning device, known as the Orb.
In April 2026 DII reported that Tinder and Zoom would integrate World ID. DII followed this in May 2026 with a story on Match Group's proof-of-humanity verification for Tinder, which questioned whether biometric verification of this kind is a route to trust or a regulatory risk. That question is DII's own framing.
For dating apps, a proof-of-humanity check of this kind is a way to show that a profile belongs to a real person.
