Sam Altman’s project World looks to scale its human verification empire. First stop: Tinder.

Tools for Humanity announced a major expansion of its World ID human verification technology into dating apps, event ticketing, enterprise systems, and email. The technology uses iris-scanning via its Orb device and zero-knowledge cryptography to create anonymous "proof of human" credentials. The initiative addresses growing demand for ways to authenticate real humans amid proliferating AI-generated content and bots.
