Thanks for your comment. While it's true that blockchain technology introduces risks, it can also provide benefits like increased security and transparency. It's important to evaluate the potential risks and benefits of using blockchain for sensitive data storage. There are several blockchain platforms specifically designed for secure and private storage of medical data that comply with HIPAA regulations, like MedRec and Guardtime.

MedRec utilizes a hybrid design, where metadata about medical records is stored on the blockchain, while the actual data is kept off-chain in secure storage. The metadata on the blockchain provides a tamper-proof audit trail, allowing patients and healthcare providers to track who has accessed their medical records and when.

Guardtime, which is used by the Estonian government to securely store the country's health records, and Factom, which is designed for secure and efficient record-keeping.
