This paper presents a Web3-based healthcare system integrated with the Republic of Korea's MyHealthWay platform for secure and user-controlled management of personal health data. The system combines decentralized identifiers, smart contracts, distributed storage, and the HL7 FHIR standard to support decentralized authentication, access control, and interoperability. A conceptual demonstrator, HealthCube, validates feasibility by enabling privacy-preserving health data processing through computation on encrypted data without exposing original information.
