IRIS Chain is a blockchain-based digital identity and health infrastructure project that uses AI-powered iris recognition to provide decentralized identity verification (DID) and personalized healthcare services. By integrating biometric data with blockchain and AI, IRIS Chain enables secure, non-invasive health monitoring and digital ID issuance across devices such as KIOSKs and smartphones. The IRC token serves as a utility token for subscribing to health services, accessing AI-based health analytics, verifying user identity via APIs, and participating in future staking/governance mechanisms. The project aims to build a globally accessible health-data and identity protocol compliant with data privacy regulations (e.g. GDPR), currently active across Japan, Korea, China, and Vietnam.
