Vitalik Buterin, co-founder of Ethereum, has expressed reservations about the digital identification approach promoted by Sam Altman's World project. World, previously known as Worldcoin, was created under Altman and Alex Blania's Tools for Humanity. The organization aims to distinguish between AI agents and human beings by scanning users' eyeballs and creating a unique identity for them on the blockchain. In a detailed post, Buterin acknowledged that World's approach of using zero-knowledge proofs to verify human identity while protecting anonymity is also being explored by various digital passport and digital ID projects. He noted that using a "ZK-wrapped digital ID" could potentially contribute to protecting social media, voting, and internet services against manipulation from sybils and bots, all without compromising on privacy. However, Buterin argued that this approach ultimately boils down to a "one-per-person" ID system, which creates significant risks. He pointed out that in the real world, pseudonymity generally requires having multiple accounts, and under a one-per-person ID system, even if ZK-wrapped, there is a risk of moving closer to a world where all activity must de-facto be under a single public identity. Buterin's concerns highlight the potential trade-offs between digital identity verification and individual privacy, and the need for careful consideration of the implications of such systems.
