That doesn't make sense. Read accesses couldn't possibly be logged. You probably wouldn't want sensitive information like health records in a block chain. The risk for leaks is obvious.
Both credit cards records and health records are data where there is a single authoritative data source. You want to know who actually accessed the data, and not any sort of decentralized consensus about the matter.
Agree about the wider aspects however, but those are probably about payouts to stakes in immaterial data or zero knowledge trading of cryptographic keys rather than your health data.
- csydas 9y agoThis is especially true for Health Records with regards to US Health Care, as access control is heavily monitored and Hospital Employees are instructed clearly and frequently that you do not access records for anyone you are not treating, accidental access needing to be reported, and so on. Confidentiality of the patient records requires a clear system to see who accessed what, when, and from where they accessed it. Blockchain seems like a complete mismatch for such an endeavor.
- subway 9y agoJust because a node can participate in a blockchain and cryptographically verify the chain doesn't mean the node can access the plaintext of every record in check chain. Check out permissioned implementations like JP Morgan's Quorum.
