Ethereum co-founder Vitalik Buterin warns that Sam Altman's supported digital identity project, World, may pose a threat to the pseudonymous system on the internet. Vitalik stated that although World uses zero knowledge proof technology to protect privacy, its "one ID per person" design may result in all user activities being tied to a public identity, weakening anonymity protection. He suggested adopting a 'diversified identity model' to avoid having a single institution control the identity system. （TheBlock） https://www.
