SAM ALTMAN’S IRIS-SCANNING, humanity-verifying World project announced at an event in San Francisco on Friday that Tinder users around the globe can now put a digital badge on their profiles signaling to potential suitors that they’re a real human, provided they’ve already stared into one of World’s glossy white Orbs and allowed their eyes to be scanned. The announcement follows a pilot project for Tinder verification that World previously conducted in Japan.

The global Tinder expansion is one of the biggest tests yet for World, and the company’s bet that everyday consumers will be willing to sign up for biometric verification services to use internet applications. Founded in 2019 by Altman and Alex Blania, the World project was designed for a future where the internet is overrun with highly capable AI agents that make it incredibly difficult, if not impossible, to tell who is really human. As companies like OpenAI—where Altman is CEO—and Anthropic push AI agents into the mainstream, the problem World was built to solve feels increasingly urgent.

But World has struggled to achieve mainstream adoption, and it has encountered resistance from governments around the globe that have probed the company over suspected violations of data protection laws. The company says 18 million people have now been verified with an Orb, up from 12 million last year.
