$WLD World ID
This verification is done with World ID, the system that acts as a digital passport and that users can store on their devices to prove they are human and not robots. With its new version (World ID 3.0), it optionally supports NFC-enabled physical passports through the World App.
According to details in the official blog, the data stored from the device is inaccessible "to World Foundation, TFH or any third party". World ID 3.0 also features anonymized multi-party computation (AMPC) technology to anonymize and securely protect the identity data of World ID holders.
"MPC incorporates the latest advances in multi-party cryptographic protocols and further improves state-of-the-art techniques. This ensures that no iris code ever leaves the user's device," they assure.
World ID 3.0 also comes with online anti-fraud protection using 'Deep face' technology. With it, they aim to combat impersonation with 'deepfakes' in video calls or real-time chats, and for this, it combines images from orb, personal data custody, and authentication with facial recognition.
World Chain
Both World ID and the World app have been integrated into World Chain, the blockchain that supports transactions in the World project and is built on Ethereum.
World Chain was activated this Thursday and, according to its leaders, is "the chain with the largest number of individually verified humans," specifically, 15 million users who have migrated or are in the process of migrating from World ID; and it is backed by service providers such as Optimism, Alchemy, Uniswap, Safe, Dune, and Etherscan.
