Worldcoin is a project that fuses digital identity verification with cryptocurrency. Users who submit to an iris scan via a spherical device called the Orb receive a digital identity credential known as a World ID; verified users are then rewarded with WLD, the project's governance token. In South Korea, WLD is listed and actively traded on major won-denominated exchanges including Upbit and Bithumb.

Origins

Worldcoin traces its roots to 2019, when Sam Altman—chief executive of OpenAI, the company behind ChatGPT—co-founded Tools for Humanity alongside Max Novendstern and Alex Blania. Altman's animating concern was that advances in artificial intelligence would make it increasingly difficult to distinguish real human beings from automated bots online. His thesis: as AI floods the internet with machine-generated content, the ability to prove one's humanity would itself become critical infrastructure. After raising $250m from prominent venture capital firms including Andreessen Horowitz (a16z), the project launched formally in 2023. In 2024 it rebranded as "World" and broadened its ambitions to encompass digital identity verification more generally.

What the Project Does

The centrepiece of the technology is the Orb, a globe-shaped iris-scanning device. When a user looks into it, the Orb scans their iris and generates a unique biometric code called an IrisCode, which is then converted into an encrypted hash and stored. The company says it does not retain the original iris image; only the encrypted hash is kept, distributed across a decentralised system to protect privacy. Once verified, users receive a World ID—essentially a digital passport—and any WLD tokens they earn are held in a wallet within the World app.

World ID is designed to be more than a mechanism for collecting token rewards. The project positions it as a decentralised identity layer that could be used for online voting, human-versus-bot verification, and, in the longer term, the distribution of a universal basic income. As of May 2026, Nasdaq-listed Eightco Holdings had accumulated WLD equivalent to roughly 8.3% of the circulating supply, making it the project's largest known institutional holder—an early sign that some companies are treating WLD as a treasury asset.

Controversies and Regulatory Setbacks

The most serious challenge Worldcoin faces is a mounting backlash over the collection of biometric data. In August 2023, Kenya suspended new sign-ups over data-protection concerns. In May 2025, a Kenyan high court went further, ruling the Worldcoin Foundation's activities unlawful and ordering the permanent deletion of all collected biometric data within seven days. The court found that the project had violated Kenya's Data Protection Act, had failed to conduct a valid data protection impact assessment, and had used financial inducements to obtain users' consent.

Around the same time, Indonesia's Ministry of Communication and Information Technology suspended the project's operations in the country for breaching electronic-system regulations. In Europe, Spain's data protection authority (AEPD) issued a temporary ban in 2024 under the EU's General Data Protection Regulation (GDPR) emergency procedures, while regulators in Britain and Germany launched investigations into the legal basis for the project's data processing. In the United States, regulatory uncertainty kept the service off the market for years; it was only in late April 2025 that iris-scanning stations and WLD airdrops began appearing in a handful of cities, including Atlanta and Los Angeles.

Assessment

*Investment risk: ★★★★☆* Regulatory risk is live and escalating. Court rulings and operating bans across multiple jurisdictions remain an ongoing concern for investors.

*Technical maturity: ★★★☆☆* The project claims its zero-knowledge-proof architecture protects user privacy, but fundamental scepticism about the collection of biometric data itself has not been dispelled.

*Ecosystem scalability: ★★★☆☆* Verified user numbers are growing steadily in Asia—South Korea, Japan and Singapore among them—but regulatory barriers in major markets mean the pace of expansion varies sharply by region.

*Overall interest: ★★★★☆* Sam Altman's personal association with the project and the broader question of how to prove humanity in an age of AI continue to command considerable attention.
