摘要

The management of electronic health records (EHR) presents ongoing challenges, particularly concerning the security, ownership, and ease of access to medical data. This paper proposes a novel framework for EHR management, utilizing blockchain technology, the InterPlanetary File System (IPFS), and ERC721A-based Soulbound tokens (SBTs) to give patients full control of their health records. These records are securely stored in a decentralized system, which also protects against tampering. Healthcare providers act as custodians to ensure data availability by pinning these records on IPFS. By leveraging ERC721A-based SBTs, we enable efficient linkage of medical data to non-transferable tokens, lowering gas costs and ensuring privacy. This approach enhances the scalability and efficiency of medical data management in line with current demands in healthcare.
