Years of regulation have stifled tech development in medical data management, while an array of incompatible back-end systems and fragmented data trails limit patients’ ability to engage with their medical history. We have developed MedRec, an open-source program that applies blockchain smart contracts to create a decentralized content-management system for healthcare data, and have piloted the project with Beth Israel Deaconness Medical Center. MedRec sets up an authentication log to govern medical record access, while providing means for auditability and data sharing. Its modular design integrates with providers’ existing, local data storage solutions, enabling interoperability. The system engages directly with medical researchers, who provide the “mining” needed to secure and sustain the authentication log on a private, Ethereum network. Read the whitepaper here.
