Worldcoin has announced the launch of its own layer-2 blockchain, named 'World Chain', aimed at supporting verified human identities. The initiative has already seen significant engagement, with 5 million people verified through its innovative iris scanning technology, and over 10 million accounts created. This layer-2 blockchain is designed to prioritize verified humans and is part of Worldcoin's broader strategy to scale its operations without compromising on user experience. The company's use of zero-knowledge proofs (ZKPs) is intended to ensure privacy while proving humanity, which could revolutionize fee structures and minimize maximal extractable value (MEV) issues in crypto transactions.
