Vitalik introduces ‘pluralistic’ IDs to protect privacy in digital identity systems

Vitalik Buterin warns that single digital IDs could erode pseudonymity, proposing pluralistic systems to safeguard privacy and fair access.

Ethereum co-founder Vitalik Buterin has introduced a new kind of digital identity system dubbed “pluralistic identity,” arguing it could protect privacy while enabling fair participation in digital life.

In a blog post published Sunday, Buterin explored the promise and pitfalls of zero-knowledge (ZK) proof-wrapped IDs, warning that even privacy-preserving systems can carry serious risks if they rigidly enforce one identity per person.

The Ethereum (ETH) mastermind noted that many new digital ID projects use zero-knowledge proofs to let users prove they have a valid ID without revealing personal details. Examples include World ID, which has surpassed 10 million users, Taiwan’s digital ID project, and European Union initiatives increasingly adopting ZK technology.
