World Releases World ID v4.0, Introducing Account Abstraction and Multi-Key Support

Odaily News: World (formerly Worldcoin) announced the release of World ID v4.0, introducing an account abstraction architecture into the protocol system. This upgrade transitions World ID from a single-key mechanism to an abstract record within the public registry "WorldIDRegistry," supporting multiple authorized keys. This enables users to generate identity verification proofs across different devices or platforms.

World stated that the core improvements of the new version include: support for multi-key and multi-validator management, enhancing usage flexibility while maintaining the same identity; strengthening protocol resilience by introducing key rotation, revocation, and optional recovery agent mechanisms; launching a web-based reference verifier to simplify the browser-side experience; generating one-time nullifiers via OPRF nodes to enhance privacy protection; and simultaneously adding a relying party registry to help verifiers identify request sources, prevent phishing attacks, and lay the groundwork for introducing protocol fee mechanisms in the future.
