  • Vitalik Buterin praises Worldcoin’s privacy and data handling methods.
  • Worldcoin’s efforts aim to establish a global, unique digital identity system.
  • Multiple governments have banned Worldcoin due to privacy concerns. 

Worldcoin has been in the spotlight for its novel approach to creating a universal digital identity through iris scanning. However, this method has not been without its critics, who raise concerns over the potential for privacy infringement.

Despite the criticism, Vitalik Buterin, the co-founder of Ethereum, recently voiced his support for Worldcoin’s efforts to address these privacy concerns. Privacy is a top issue for the project, as it relies on biometric data, scanning users’ irises to create a unique digital identity for each user. 

Buterin Commends Worldcoin for Taking Privacy Seriously

On Friday, March 29, Vitalik Buterin, known for his pioneering work with Ethereum, recognized Worldcoin’s efforts to balance creating a universal digital identity with the need for stringent privacy measures. 

In a Tweet reply to tech writer Louis Anslow, Buternin commended Worldcoin for “taking privacy concerns seriously.” He also highlighted the project’s advances in cryptography, making its approach “data minimal.”


There are many privacy concerns, and they primarily revolve around the potential misuse of biometric data. Specifically, Worldcoin’s system stores hashed versions of iris scans and claims this system protects user’s privacy. Despite this, there are still worries about potential identity theft. 

The potential for hacking, coercion, and system misuse, such as selling or renting IDs, presents significant security risks. Buterin also stresses the importance of a reliable mechanism for identity recovery to prevent financial loss and misuse.

Worldcoin Banned, Investigated in Multiple Countries

Buterin’s latest remarks came when multiple governments have investigated or outright banned Worldcoin. For instance, Kenya has been a significant market for Worldcoin, before suspending orb scanning over privacy concerns. The suspension remains until authorities are convinced there’s no risk to the public. 


In France, investigations into Worldcoin focus on its biometric data collection practices, questioning their compliance with data protection regulations. Additionally, the UK’s Information Commissioner’s Office announced it would be investigating the company. 

Argentina has also opened an investigation into Worldcoin, examining its handling of personal data amid growing concerns over the project’s adherence to privacy laws​​. Moreover, Spain temporarily banned Worldcoin operations over similar issues for up to three months. 

On the Flipside

  • Worldcoin aims to create a universal digital identity to simplify and secure online verification processes. The goal is to make it easier for individuals to access services and for companies to authenticate users. 
  • A security audit published on March 15 found that Worldcoin has no security vulnerabilities. The audit came after a major hack to the network. 

Why This Matters

The discussion surrounding Worldcoin and its potential use cases sheds light on the broader implications for digital identity. However, the project has to navigate major challenges, especially regarding privacy protection.
