How to Avoid a Dystopian Digital ID System
summary
Critique centers on a proposed EU wallet design that uses salted-hash linkability, which makes repeated presentations linkable and mirrors some US mobile driver’s license designs, while practical alternatives use zero-knowledge proofs (Aztec, ZK Passport, Google Longfellow open source) and MPC for private computation—MPC powers a Worldcoin-style iris uniqueness check at scale with 15 million iris checks and Buenos Aires deploys a ZK wallet serving 3.6 million Buenos Aires users; recommendation: open standards, threat modeling, privacy-by-design, and a competitive, auditable wallet marketplace.
