World ID has launched a significant upgrade to its protocol, now reaching 18 million users across 160 countries. This update introduces integrations with Tinder and Zoom, enhancing user authenticity and security. Tinder users can now obtain a "Real Person Verification Badge," while Zoom incorporates anti-deepfake verification to ensure participants are real. Additionally, the new Concert Kit tool aims to prevent ticket scalping through authentication. The upgrade also includes a standalone World ID app (beta) for cross-platform identity verification and open-sources its SDK for third-party development. Technical enhancements feature multi-key management, key rotation, and account recovery, promoting "Human Continuity" for consistent user verification. Reddit, Razer, and Mythical Games are exploring or have integrated these standards. World ID's business model charges applications based on active users, with fees settled via on-chain wallets or third-party services.
