In recent years, blockchain technology has emerged as a promising solution to enhance the security and interoperability of Electronic Health Records (EHRs). Traditional EHR systems face significant challenges regarding data privacy, security, and trust, as they rely on centralized databases that can be vulnerable to breaches. This paper explores the application of blockchain technology to EHR systems, focusing on the potential to secure patient data, ensure data integrity, and facilitate seamless data sharing across healthcare institutions. The decentralized nature of blockchain ensures that health records are immutable and transparent, which mitigates the risks of unauthorized access and fraudulent alterations. Additionally, smart contracts can be utilized to enforce access control policies, ensuring that only authorized entities can view or update patient records. We propose a novel blockchain-based framework for managing EHRs, integrating the principles of cryptographic hashing, consensus algorithms, and distributed ledger technologies. The paper further evaluates the feasibility and benefits of this system through case studies, demonstrating how blockchain enhances patient privacy, streamlines data sharing, and improves overall healthcare service delivery. Italso discuss the limitations of current blockchain implementations in healthcare, such as scalability issues, regulatory challenges, and integration complexities. Finally, we provide insights into the future direction of blockchain adoption in EHR systems, emphasizing the importance of interoperability standards and cross-platform compatibility. This research contributes to the growing body of knowledge on blockchain in healthcare and provides a foundation for future advancements in secure and decentralized health information systems.
