Worldcoin Announcement
summary
Worldcoin announces a biometric-onboarding stack using iris-scans via the Orb that generates on-device uniqueness codes and Semaphore-style zero-knowledge proofs for anonymous one-person-one-account primitives. The World App reports 2M+ users and ~600k smart wallets deployed on Optimism, with 350 projects and 1,000+ developers already integrating. Migration to the Superchain surfaces practical lessons: L2 gas spikes from mass account deployment, high calldata costs on rollups, and a compression trick (store one EC coordinate) to cut zk proof costs. World ID SDK is open source.
