Blockchain has the potential to revolutionize healthcare data management by providing a standardized and decentralized system for storing electronic medical records. It allows different healthcare stakeholders secure access to patient data without special software or databases. By encrypting data and only allowing access with a private key, blockchain increases security and privacy compared to traditional systems. It also gives patients more control over their own health data by allowing them to own and potentially sell their genomic data if they choose. Overall, blockchain could significantly improve how electronic health records are securely shared and stored across the healthcare industry.
