Worldcoin / World ID
Web3 / privacy technology
Worldcoin is a cryptocurrency and proof-of-personhood project co-founded by Sam Altman that uses biometric iris-scanning hardware called the Orb to verify unique human identities and issue World ID credentials. Participants visit an Orb location, undergo iris scanning, and receive a unique identifier and access to the Worldcoin token (WLD). The system operates across multiple countries and aims to create a global identity layer independent of governments or traditional institutions. World ID credentials can be used for airdrops, governance, or other Web3 applications requiring proof of unique personhood while maintaining privacy. Example: A user in Argentina visits a Worldcoin Orb, completes iris verification, and receives a World ID credential that qualifies them for WLD token airdrops and grants access to decentralized governance systems that require proof of unique humanity. Why it matters for privacy technology: Worldcoin demonstrates how biometric systems can establish privacy-preserving identity verification at scale without exposing personal data. Its approach balances anonymity with uniqueness, addressing sybil attacks in Web3 while raising important questions about data custody and regulatory compliance.
