World ID app is built on World ID 4.0, the latest release of the World ID protocol, which raises the bar for post-quantum privacy and security. For enterprises, it operates at production grade and is designed to be resilient to compromise, recoverable if access is lost, and compatible with existing security infrastructure and systems. For consumers, World ID is intuitive, portable, and private by default, allowing individuals to recover access, manage Proofs, and interact across apps, while preserving privacy. These features are made possible through design choices like one-time-use nullifiers, which prevent interactions from being linked or correlated, alongside a system architecture that ensures no personal data is exposed or stored. A person can establish Proofs about themselves and delegate them to an agent, allowing the agent to confirm those Proofs to a third-party platform. World ID app gives individuals a place to manage those Proofs and how they are used.
