Biometric iris scanning launches in US cities for digital identity

OpenAI CEO Sam Altman, known for creating ChatGPT, has launched World, a project that uses an eye scan to prove you are a real person online. The idea is to help people stand out from bots and AI by creating a digital ID with a quick scan from a device called the Orb.

While Altman says this technology keeps humans central as AI advances, it also raises serious concerns about privacy and the security of sensitive biometric data, with critics and regulators questioning how this information will be used and protected.

How World ID works

World ID relies on a device called the Orb, a spherical scanner that captures a person's iris pattern to generate a unique IrisCode. It stores the code on a blockchain-based platform, ensuring that users can verify their identity without revealing personal details.

Once scanned, individuals receive their World ID, which can be used for authentication across various platforms where the World ID protocol has been integrated, including Reddit, Telegram and Shopify.

Additionally, those who sign up are rewarded with WLD cryptocurrency as an incentive. They get the equivalent of $40 worth of tokens, which they can spend, exchange or share with other World ID holders.
