Product Announcement
summary
Worldcoin announces joining the Optimism Superchain and lays out specific engineering choices: a hardware Orb iris scanner that keeps raw images on-device, a privacy-preserving World ID built with zero-knowledge proofs, a World App mobile wallet now handling 1.7M users and deploying 1.7M Gnosis Safes, and a period of subsidized meta-transactions that cost about 1.5 trillion gas so far. Migration to an EIP-4844 enabled OP Stack targets cent‑level fees and mobile ZK proof generation to scale toward a billion users.
