In contrast to traditional paper-based medical records, electronic health records (EHRs) have gained widespread adoption due to their efficiency, enhanced security, and the reduction of data redundancy. Despite these advantages, EHRs continue to grapple with issues related to poor interoperability and unresolved privacy concerns. Blockchain, as a distributed ledger protocol utilizing encrypted blocks of data organized in chains, emerges as a promising solution to address the shortcomings of EHRs, particularly in terms of interoperability and privacy. This paper delineates the definitions of EHRs and blockchain technology and introduces several established schemes based on blockchain to bolster EHR interoperability and enhance privacy protection. The discussion also encompasses a review of current challenges in areas such as data management efficiency, fair access, and trust in existing systems. As part of this commentary, we propose ongoing research needs in health informatics, data sciences, and ethics to establish EHRs based on blockchain technology. It is imperative for blockchain-based EHR schemes to navigate potential challenges, including addressing healthcare resource inequalities, mitigating the substantial carbon footprint associated with computational needs, and managing potential distrust among health providers and patients stemming from the widespread use of blockchain technology. text.
