Sam Altman’s project that aims to scan the irises of every single person on Earth in exchange for cryptocurrency has made its debut in the U.S., even as concerns around biometric data collection and processing remain.

Sam Altman’s controversial blockchain project, World, is launching in the U.S. – and said it intends to roll out 7,500 eye-scanning “orbs” in cities across the country by the end of the year.

World Network, OpenAI CEO Sam Altman’s controversial cryptocurrency project, opened a new storefront Thursday in Union Square that features the organization’s signature iris-scanning orbs.
