Vitalik Buterin Critiques World Project’s Privacy Risks and One-Per-Person ID System

Vitalik Buterin, co-founder of Ethereum, has expressed concerns about Sam Altman’s World project, now rebranded from Worldcoin. The project, developed by Altman and Alex Blania’s Tools for Humanity, proposes a system where human identities are verified through unique eye scans, stored on the blockchain, to distinguish humans from AI agents. Buterin acknowledges the potential of zero-knowledge proofs (ZKPs) in protecting privacy and preventing manipulation by bots, but he warns against the risks of a ‘one-per-person’ identity system. He argues that pseudonymity in real life often requires multiple identities for protection. In a world with increasing surveillance, such as government demands to make social media accounts public, this new system could compromise individual privacy. Buterin advocates for a more pluralistic approach to identity, where multiple systems exist without a dominant authority. He believes merging social-graph-based identity systems with current one-per-person identity projects could offer a more balanced solution. The debate touches on broader concerns about privacy, government control, and the future of digital identity management.
