Belltane Organizes Atlanta Hyperledger Meetup

Belltane has organized the Atlanta Hyperledger Meetup. Interest in this exciting new Blockchain technology is high and over 20 people signed up in just the first 2 days! We are planning our initial meeting, so join now to help set the agenda and location.

Hyperledger is an open standard for Blockchain for Business and is an open source collaborative effort created to advance cross-industry Blockchain technologies. It is a global collaboration, hosted by the Linux Foundation, including leaders in Finance, Banking, Internet of Things, Supply Chains, Manufacturing and Technology.

The Hyperledger Fabric provides a foundation for developing Blockchain solutions with a modular architecture, pluggable implementations, and container technology. While leveraging open source best practices, Hyperledger Fabric enables confidentiality, scalability, and security in business environments.

Belltane has utilized the Hyperledger Fabric and the Node.js Client SDK running on IBM Bluemix to publish a very basic Healthcare Provider Directory Proof of Concept and continues to explore and develop components, applications, and partners to take advantage of the many benefits of the Blockchain for Business capabilities of the Hyperledger Fabric.

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.

Belltane Releases MapShare GPS Location Tracking for Android

Belltane has published MapShare for Android, a GPS shared location tracker. MapShare uses IoT (Internet of Things) technology to allow near real time location tracking of family and friends on a Google Map. Users can choose their own images for each of their shared mappers, and control location sharing by mapper.Get it on Google PlayMapShare is ssl encrypted for security, and using IoT technology eliminates the need to store any information on our servers. No user data is collected or stored, and so no personal information can ever be sold to third parties.

MapShare is available in 136 countries around the world, providing global sharing of locations among far-flung family and friends.

Additional functionality is planned, and we invite suggestions and requests.

MapShare is a consumer version of Belltane’s IoT technology capabilities. Businesses with custom location tracking or other device to device data sharing requirements should contact us for more information about Belltane IoT applications and services.
