Vitalik Buterin outlines ‘four major risks’ with Worldcoin following token launch.

#Ethereum co-founder #Vitalik Buterin highlighted four potential pitfalls of Worldcoin's iris-scanning identity verification solution, co-founded by #OpenAI CEO Sam Altman, which launched its WLD token earlier today.

Buterin pointed to privacy, accessibility, centralization and security as the major risks associated with #Worldcoin’s Proof-of-Personhood (PoP) construction and proposed an alternative solution to mitigate against them

PoP is a system designed to authenticate the uniqueness of a user in a decentralized way without relying on a central authority or revealing personal information. Use cases include avoiding Sybil attacks by preventing multiple account creation, event tickets, airdrops and DAO voting.
