Here's a legitimate question, how does Patientory store big files that's in the gigabytes worth of MRI and CT images? Does Patientory need to link up with Siacoin or Storj to work together? I'm not familiar with decentralized storage. Blockchain is not very efficient when it comes to large files.

Patientory hasn't addressed this problem yet and if anyone who understands blockchain can explain it to me, that would be great.

Dev please answer question: how do you store big data on chain? this not possible. community must know if project not possible.

In white paper I see:

"The limitation of the blockchain to host private information may be overcome through data obfuscation, such as encryption, but in the event that the decryption key is ever leaked, there is no way to remove the sensitive data itself from the blockchain"

"we implement a mechanism for the persistent storage of sensitive information through the use a private implementation of an Ethereum based blockchain"

but then I see:

"The HIPAA compliant storage facility hosts the actual data"...what is HIPAA compliant storage facility and who owns the hardware? who pays for the data storage?

"Patients are given an allotted amount of space to store information for free on the Patientory network". how you give storage for free? what you mean store on the network?

So far I read white paper many times and I think it still no make sense.
