The misconception of "Storing Medical Records on Blockchain" vs. Data Integrity

Hey everyone, I just joined the forum and wanted to drop some thoughts from my background. I specialize in Health Data Interoperability, mainly working with the HL7 FHIR standard, and I'm diving into Digital Health research. It seems like a lot of new crypto projects are touting the idea of "storing patient records on the blockchain". From a tech and architectural view, this is often not the right approach and usually leads to trouble. Medical data can be super bulky (think imaging and history logs) and privacy laws like GDPR make it risky to keep sensitive personal info in an unchangeable format. In my opinion, the real big deal for Blockchain in healthcare isn't about storage but about ensuring Integrity. The model I'm exploring involves: Keeping the real data on traditional off-chain servers (using FHIR resources for standardization). Creating a cryptographic Hash of that data. Only anchoring the Hash on the Bitcoin blockchain. This way, we can make sure the medical history remains untouched without bloating the blockchain or putting patient data at risk. I'd love to hear if anyone knows of any active projects that are focusing on this "Integrity/Timestamping" aspect instead of just trying to be a full storage solution. Best wishes!

You need to research usage of blockchains outside of the crypto coins world... They are widely used for logistics, food production, manufacturing and forensic records storage - anywhere secured immutable data is required. They are private blockchains having nothing to do with crypto ones. Doing a search using "IBM blockchain" or "Intel blockchain" should get you pointed in the right directions.
