World

World (formerly Worldcoin) is building a global "proof of human" network for the AI age. Created by Tools for Humanity and co-founded by OpenAI's Sam Altman and CEO Alex Blania, World lets people prove they are a real, unique human online without revealing who they are. Users verify with the Orb, a custom iris-scanning device, and receive a private World ID plus access to the World App, World Chain (an Ethereum Layer 2), and the WLD token. The pitch is simple: as AI makes bots indistinguishable from people, the internet needs a privacy-preserving way to tell humans apart from machines.
