The update introduces a new World ID app, currently in beta, allowing users to manage credentials and interact across platforms. World ID for AI agents links AI agents to a verified human. The upgrade also adds enterprise-ready features like multi-key support, key rotation, recovery, and session management, along with "human continuity," which verifies that the same real person is present across interactions. World also launched Concert Kit, a tool designed to ensure concert tickets go to real verified fans. To date, World has issued over 18 million Orb-verified credentials.Sponsored byLido Earn lets you deploy ETH or stablecoins into curated DeFi strategies for optimised yield.
