World launches World ID 4.0 with account-based architecture and Tinder, Zoom, Docusign integrations at 18M verified users

At its Lift Off event in San Francisco on April 17, World unveiled World ID 4.0 — a full-stack proof-of-human protocol with account-based architecture, key rotation, multi-key support, and single-use anonymity nullifiers. Launch integrations span Tinder (US rollout today), Zoom (Deep Face in meetings), Docusign, Okta, Vercel, and VanEck, plus a new World ID mobile app in public beta. The network now spans nearly 18 million verified humans across 160 countries, positioning proof-of-human as critical infrastructure for the AI agent era.
