World releases World ID v4.0, introducing Account Abstraction and Multi-Key Support

BlockBeats News, January 29. World (formerly Worldcoin) announced the release of World ID v4.0, introducing an account abstraction framework into the protocol system. This upgrade transitions World ID from a single-key mechanism to an abstract record in the public registry "WorldIDRegistry," supporting multiple authorization keys to allow users to generate identity proofs across different devices or platforms.

World stated that key improvements in the new version include: support for multi-key and multi-validator management to enhance user flexibility while maintaining the same identity; enhanced protocol resilience through key rotation, revocation, and optional recovery agent mechanisms; the introduction of a web-based reference validator to streamline the browser-side experience; generation of one-time null symbols by OPRF nodes to strengthen privacy protection; and the addition of a trust anchor registry to help validators identify request sources, prevent phishing attacks, and lay the foundation for future protocol fee mechanisms.
