Key Highlights
World unveiled World 4.0, a major architecture upgrade adding account-based identity, multi-key support, and an AI agent credential layer to its iris-verified human ID system.
New partnerships with Tinder, Zoom, and DocuSign embed proof-of-human checks directly into dating profiles, video calls, and digital agreements.
The network has reached 18 million verified users across 160 countries, though the project continues to face regulatory restrictions in multiple jurisdictions.
Sam Altman's identity project, World, announced its World 4.0 upgrade at an event in San Francisco on April 17, positioning the release as the most significant technical overhaul since the project rebranded from Worldcoin. The upgrade targets a problem that has grown measurably worse with generative AI: the difficulty of confirming that the person on the other side of a screen is actually human.
The core of World's approach remains the same. Users scan their iris at a physical Orb device, which generates a unique cryptographic code without retaining the original biometric image. World 4.0 adds account-based identity, multi-key support, and account recovery on top of that foundation. It also introduces AgentKit, which lets verified users delegate their proof-of-humanity credential to AI agents, enabling automated actions that still carry a verified-human backstop.
The partnership rollout puts that infrastructure into platforms where synthetic identities cause the most direct harm. Tinder will display a "verified human" badge on profiles that have completed World verification. Zoom is adding a "Deep Face" feature that flags meeting participants who cannot pass a real-time humanity check. DocuSign is weaving proof-of-human into its agreement flow, a direct response to AI-generated signatory fraud. Separately, a Concert Kit tool will let artists reserve event tickets exclusively for verified individuals, cutting out scalper bots.
Thailand ordered the deletion of 1.2 million iris scans in November 2025. Germany cited GDPR violations. Colombia ordered operations closed in October 2025, and both Hong Kong and Singapore put in place their own restrictions. The company has not disclosed how it plans to offer the Tinder, Zoom, and DocuSign integrations in markets where it cannot legally collect iris data.
