The document proposes implementing a blockchain-based architecture to secure electronic health record (EHR) systems. Key benefits of using blockchain for EHRs include improved data sharing and interoperability between healthcare providers, increased data access for patients, and enhanced security and privacy of patient medical records and data. The proposed system would use blockchain instead of a traditional client-server architecture for EHRs to increase efficiency and security. It discusses related work applying blockchain to healthcare and EHR systems and potential issues that need to be addressed.
