On October 17th, Worldcoin, the blockchain project co-founded by Sam Altman and Alex Blania, rebranded to "World" and launched "World Chain," a new blockchain designed to prioritize humans. Built on the OP Stack as part of the Optimism Superchain, World Chain aims to scale Ethereum. The project introduced the new Orb 2.0 device, featuring five times the AI power of its predecessor, to verify individuals' identities and enhance the World ID system. World announced that as of the launch, all of its approximately 15 million World ID holders and World App users have either migrated or are in the process of migrating to World Chain. Additionally, World Chain is now live on Uniswap, and MoonPay is a launch partner, enabling users to buy and sell the World token. The new World ID 3.0 introduces World ID Credentials, allowing more people to participate using methods like an NFC-enabled passport. Notably, one in three adults in Buenos Aires are now verified on the platform. The launch event in San Francisco showcased enthusiasm around these developments, signaling a significant step forward for the company.
