Worldcoin controversy: Brazil joins nine other countries in stopping Sam Altman’s initiative

By · August 14, 2023 · 2 min read

Worldcoin, a project by Sam Altman, has become a focal point for debate. The platform, via Orbs, involves scanning users’ irises to achieve a unique biometric identification for each individual, allowing them to access a proprietary cryptocurrency.

Amid rising concerns over data security and individual privacy, several countries, including Brazil recently, have temporarily halted its operations.

To utilize Worldcoin, users download a mobile app and receive a QR code.

A subsequent scan from a metallic sphere captures their iris pattern, linking this biometric data to their QR code.

This process then creates a ‘World ID’, serving both as a digital identification and a cryptocurrency wallet for Worldcoin.

The decision by Brazil to suspend Worldcoin’s operations arises from uncertainties about the legitimacy of such operations and concerns over users’ consent clarity, especially when terms of data sharing aren’t available in local languages.

Including Brazil’s recent move, a total of ten countries, namely Kenya, Nigeria, Argentina, Germany, France, Italy, the Netherlands, Spain, and the UK, have expressed reservations about this venture from OpenAI’s CEO, Sam Altman.

Some experts have remarked that Worldcoin offers an unusual spin on the classic capitalistic philanthropic narrative.

Anthropologist Sofie Henriksen comments on how tech giants increasingly leverage their philanthropic ventures as testbeds for new tech, expanding user bases, and gathering personal data to refine algorithms.

While Worldcoin asserts that user data remains secure and solely for cryptocurrency distribution purposes, lingering privacy apprehensions suggest that they may continue facing operational challenges in countries that have implemented suspensions.
