Worldcoin is a cryptocurrency and digital identity project co-founded by Sam Altman, Alex Blania, and Max Novendstern. It aims to create a global digital identity system called "World ID," which verifies that a user is a real human (as opposed to a bot) through iris scans using a device called the Orb. In return, users may receive Worldcoin tokens (WLD). The project’s goal is to support secure online identity verification and enable broad access to digital and financial systems.
