Worldcoin, co-founded by OpenAI CEO Sam Altman, Alex Blania, and Max Novendstern, is one of the most ambitious and controversial projects at the intersection of AI and crypto. The vision: create a global digital identity system by scanning every person’s iris using a custom hardware device called the “Orb,” issuing each verified human a World ID and free WLD tokens. In a world where AI makes it increasingly difficult to distinguish humans from bots, Worldcoin argues that “proof of personhood” is a critical public good.
The Orb — a chrome, bowling ball-sized device that scans iris patterns using infrared sensors — became one of the most recognizable images in crypto. Worldcoin deployed Orbs across dozens of countries, with operators offering free WLD tokens (and sometimes cash bonuses) to anyone willing to have their iris scanned. By 2024, over 6 million people had been verified, with particular adoption in developing countries where the free tokens represented meaningful value.
The criticism has been fierce. Privacy advocates are alarmed by the collection of biometric data — iris scans are permanent identifiers that can’t be changed like passwords. Several countries (Kenya, Spain, Portugal, Hong Kong) suspended or investigated Worldcoin operations due to data protection concerns. Critics question whether people in developing countries — often the primary scanning targets — can give truly informed consent when incentivized by free tokens worth real money.
Technically, Worldcoin uses zero-knowledge proofs so that the iris scan creates a unique identifier without storing the actual iris image (the company claims images are deleted after processing). World App, the associated wallet, became one of the most-downloaded crypto wallets globally. The WLD token launched and quickly achieved a multi-billion dollar market cap. Worldcoin’s thesis may prove prescient — AI-generated deepfakes and bot swarms are real problems that proof-of-personhood could address. But the path of scanning billions of eyes to achieve this raises questions about power, consent, and surveillance that the crypto community — traditionally allergic to centralized data collection — finds deeply uncomfortable.
