Ethereum co-founder Vitalik Buterin has launched a brand new type of digital identification system dubbed “pluralistic identification,” arguing it may defend privateness whereas enabling honest participation in digital life.
In a weblog publish published Sunday, Buterin explored the promise and pitfalls of zero-knowledge (ZK) proof-wrapped IDs, warning that even privacy-preserving methods can carry critical dangers in the event that they rigidly implement one identification per individual.
The Ethereum (ETH) mastermind famous that many new digital ID initiatives use zero-knowledge proofs to let customers show they’ve a legitimate ID with out revealing private particulars. Examples include World ID, which has surpassed 10 million users, Taiwan’s digital ID undertaking, and European Union initiatives more and more adopting ZK expertise.
“ZK-wrapping solves lots of essential issues,” he wrote, however warned that “ZK-wrapped ID nonetheless has dangers,” particularly as a result of imposing one ID per individual can undermine pseudonymity and expose customers to coercion.

Single digital IDs may kill pseudonymity
One key threat Buterin recognized is that platforms may pressure customers right into a single, trackable identification, eliminating the flexibility to take care of separate pseudonymous profiles. “In the true world, pseudonymity usually requires having a number of accounts,” he stated.
With out this flexibility, he argued, customers may discover themselves in a world the place “your entire exercise should de-facto be beneath a single public identification,” heightening risks from authorities or employer surveillance.
Buterin additionally rejected the concept of utilizing “proof of wealth” alone as an anti-Sybil measure, saying it excludes individuals unable to pay and concentrates energy among the many rich. “The theoretical excellent is one thing within the center, the place you will get N identities at a price of N²,” he stated.

Buterin proposes pluralistic IDs
To attain a versatile strategy, Buterin proposed pluralistic identification methods, the place no single authority controls identification issuance, because the “finest practical resolution.”
He defined these might be specific, utilizing social-graph-based verification like Circles, or implicit, counting on a number of ID suppliers — authorities paperwork, social platforms, and others — so nobody ID good points near-total market share.
“Any type of pluralistic identification… is of course extra error-tolerant,” he famous, stating that this flexibility helps stateless people or these unable to entry conventional IDs.
In the end, Buterin argued the very best consequence would merge one-per-person identification schemes with social-graph methods to bootstrap numerous, international identification networks.
“If their market share will get too near 100%, they shift the world… to a one-per-person mannequin, which has worse properties,” he warned, stressing that solely pluralistic identification can steadiness privateness, inclusivity, and resistance to abuse.
