In the age of rapidly progressing technology, the healthcare sector is embracing the revolution of digital transformation through the widespread adoption of Electronic Health Records (EHRs). Nevertheless, the digital realm also presents notable challenges, particularly pertaining to the security and confidentiality of patients' delicate health data. This document introduces the innovative Smart GuardianChain, a blockchain-based distributed system crafted to tackle these pivotal concerns by establishing an infallible, decentralized, and impervious platform for the management and sharing of EHRs.Smart GuardianChain capitalizes on a robust consensus algorithm to ensure the integrity of EHRs, thus safeguarding the genuineness of medical records in an increasingly interconnected healthcare ecosystem. To guarantee that solely authorized entities have access to patient information, the system integrates an intricate mechanism for access control. Patients are bestowed with complete authority over their EHRs, enabling them to manage access permissions as they deem appropriate. Through extensive experimentation, our results demonstrate the scalability, efficiency, and effectiveness of the proposed system, which not only enhances security but also preserves patient privacy. By addressing the pressing privacy challenges that EHR systems face today, Smart GuardianChain stands poised to revolutionize the quality of healthcare services, fostering trust and confidence in the digital healthcare landscape.
