Tools for Humanity, the company behind Sam Altman’s World project (formerly Worldcoin), announced the largest World ID overhaul to date at an event in San Francisco on April 17. The company is positioning World ID as “full-stack proof of human” infrastructure, built on iris-scanning biometrics and zero-knowledge proofs, designed to verify that a real person is behind a digital action without revealing their identity. Tinder, Zoom, DocuSign, and Shopify are the first enterprise partners integrating the system.
What World ID Actually Does
World’s verification system uses a spherical device called the Orb to scan a user’s face and iris, generating a unique cryptographic identifier. The images are deleted after processing, according to CoinDesk. Only anonymized code fragments are sent across a distributed network to confirm the person hasn’t previously registered. The result is a credential proving someone is a unique human online without exposing personal data.
The upgrade, which TFH calls World 4.0, adds account-based identity, multi-key support, and recovery mechanisms. A dedicated World ID app, currently in beta, lets users manage credentials and authenticate across platforms.
“In the age of AI, being human will be incredibly valuable and the internet will want to know you’re human,” senior executive Daniel Shorr said at the event, according to CoinDesk.
The Integration Partners
The four launch partners cover distinct high-stakes use cases:
Tinder is expanding a World ID pilot that launched in Japan into global markets including the U.S. Verified users get a “verified human” badge on their profiles. “We are heading to a world now where there’s going to be more stuff generated by AI than by humans,” Altman told the crowd at The Midway venue, according to TechCrunch.
Zoom is working with World on a feature called “Deep Face” that verifies meeting participants are real humans rather than deepfakes, CoinDesk reported.
DocuSign is incorporating proof-of-human checks into digital agreement signing.
Shopify is integrating for commerce authentication, according to Axios.
World also announced Concert Kit, a tool that lets musical artists reserve concert tickets for verified humans to combat scalper bots. 30 Seconds to Mars and Bruno Mars plan to use it for upcoming tours, per TechCrunch. The feature is compatible with Ticketmaster and Eventbrite.
The Agent Delegation Play
The most consequential announcement for builders: World is releasing AgentKit, tooling that lets developers attach proof-of-human credentials to AI agents. A partnership with Okta creates a system, currently in beta at humanprincipal.ai, where a World ID can be tied to a specific agent. When that agent operates on the web, websites can verify a real person authorized its actions.
“We are working with firms including Okta, Vercel and Browserbase on these capabilities,” CoinDesk reported, describing the goal as establishing “a trust layer for automated workflows without requiring personal data.”
Scale and Verification Tiers
World now has 40 million app users, including nearly 18 million verified humans across six continents, according to Yahoo Tech.
To address its long-standing scaling challenge (getting your eyeballs scanned at a physical location is inconvenient), World introduced a tiered verification system. Orb scanning remains the gold standard. A mid-tier option uses an anonymized scan of a government ID’s NFC chip. A new low-tier “Selfie Check” requires only a selfie, though chief product officer Tiago Sada acknowledged the limits: “Obviously, we do our best. But it has limits,” he told TechCrunch.
The company is also expanding Orb availability in New York, Los Angeles, and San Francisco, and offering a service to bring Orbs to users’ locations.
The Timing
This announcement lands during the same week that Cloudflare and GoDaddy jointly launched AI agent identity standards for the open web, and OpenAI joined the FIDO Alliance for agent authentication standards. The question of “how do we know whether a human or an AI agent initiated this action” is becoming the central infrastructure problem of the agentic era. World is betting its iris-scanning biometrics are the answer on the human side of that equation.
