Regulators in Portugal have issued a temporary block on Worldcoin's plan to collect biometric data, causing a setback for the AI cryptocurrency project. The scrutiny on this project aligns with the increased attention on AI technology itself. Worldcoin's data collecting efforts have sparked concerns, leading to complaints about information deficiencies, unauthorized data collection from minors, and failure to delete data. The Portuguese data regulator has intervened by blocking Worldcoin's services for a 90-day period. The Worldcoin Foundation's data protection officer has assured compliance with GDPR and willingness to address concerns, including issues with underage sign-ups. This block comes on the heels of several legal disputes that Worldcoin has been involved in recently.
