Being in Clinical research Industry and working with patient data since approx. 2 decades i am very curious how the multiple groups are planning to utilize the technology for patient data storage and sharing.

 I am trying to understand, Is it really so simple to utilize the blockchain in healthcare specially for the patient data. Will it be actually possible considering multiple regulations regarding data safety & privacy?

Are there complexities which either are already taken care of or are not yet understood so not even talked about.

Also considering that this data will be global and each country has different regulations, which would be considered?

Hoping to understand this in due course of this discussion and looking forward for some experts in this field to shed lights on how this is being done currently.
