Vitalik Buterin Sounds Alarm on Privacy Risks in Sam Altman’s “World” Digital ID

Ethereum co‑founder Vitalik Buterin cautions that Sam Altman’s World project—formerly Worldcoin—relies on iris scans and zero‑knowledge proofs to create a “one‑per‑person” digital ID, which, despite anonymity, carries privacy dangers.

He advocates instead for a “pluralistic identity” system without a dominant issuer, blending multiple decentralized credentials.
