Brazil has officially prohibited Sam Altman’s Worldcoin, a contentious cryptocurrency project known for its use of iris-scanning technology.

On January 24, 2025, Brazil’s National Data Protection Authority (ANPD) released a statement, announcing its decision to enforce a preventive measure against Tools for Humanity (TFH), the company behind Worldcoin. The ruling mandates the suspension of cryptocurrency offers or any financial incentives for collecting iris data from individuals in Brazil. This action was based on concerns that the payment incentives could unduly influence individuals’ choices regarding their biometric information collection.

“The announced measure regarding Tools for Humanity takes effect on January 25,” the notice stated.

Worldcoin’s Troubles with Biometric Data

Worldcoin, co-founded by Sam Altman, aims to create a universal financial network but has faced backlash for its reliance on gathering biometric data in the form of iris scans.

The project utilizes a device called the ‘Orb’ to collect unique biometric markers necessary for verifying identity (World ID) and preventing multiple registrations. According to the company, the World ID would provide proof that the holder is a unique, living human being, thereby enhancing digital security amidst the growing influence of artificial intelligence tools.

Despite Worldcoin’s intentions to foster financial inclusion by offering universal access to digital currency, its methods have drawn criticism from privacy advocates, regulators, and governments globally.

Consent Issues Surrounding Biometric Data Collection

Authorities highlighted that monetary compensation offered by Worldcoin for data could compromise the genuine consent expected from individuals.

The ANPD clarified that consent for the processing of sensitive personal data like biometrics must be unequivocal, informed, and provided explicitly for specific purposes. The decision also emphasized that such data processing is particularly grave due to the sensitive nature of the biometric data and the challenges involved in deleting it once collected.

Given these developments, the future of Worldcoin in Brazil remains uncertain.
