Storing Images in Hyperledger Fabric (Blockchain)

At its core, Blockchain is data storage and retrieval. Typically the data is assumed to be a transaction. Hyperledger has expanded that assumption to include assets, accounts, permissions, etc. But what about images (or other large files)? The prevailing opinion seems to be to use the Blockchain to hold the pointer to the actual location somewhere else. This is fairly standard in general database design.

But should that be the case with Hyperledger? Perhaps the benefits of Blockchain encryption, security, immutability, etc., might outweigh the standard arguments for not storing images in a database. I wanted to explore this idea further, so I first decided to look at ‘can we’, and then look at ‘should we’.

Belltane Publishes Blockchain Proof of Concept

Belltane has published a Proof of Concept Hyperledger application demonstrating the use of Blockchain to allow Payors, Hospitals, Regulators, and Medical Schools to share a common distributed ledger recording the payment eligibility status of physicians in a Healthcare Provider Directory.

This very basic proof of concept seeks to illustrate the use of Hyperledger Blockchain to enable a distributed ledger application that ensures data access security. User read and write access permissions are delivered in the SmartContract applied to the Blockchain. Medical Schools create physicians, Regulators create and edit Medical Schools and Hospitals, Hospitals edit physician privileges status and Payors can check eligibility status of Hospitals and Physicians before settling payment.

This proof of concept does not seek to closely approximate the full requirements of a Healthcare Provider Directory. However we have loaded almost 200,000 Physicians, 10,000 Hospitals, 400 Medical Schools, and 50 Regulators into the Blockchain database. Each Hospital, Medical School and Regulator has 2 user names each, totaling almost 10,000 user accounts. In our security scenario, each entity user is limited to the appropriate visibility and write permissions based on its type and location. Regulators can only access physicians and entities in its state, for example.
