U.S.-based quantum dot producer QMC (Quantum Materials Corp) declared its blockchain-based QDX HealthID for transparency in disease testing and immunization for infectious diseases. The aim is to assure the authenticity of health data and aid individuals to re-join the workforce soon.

Quantum dots are nanoparticles made up of semiconductor materials that transmit various colors when illuminated by light. This color depends on their dimension and the way they were produced. QMC has built a track and trace solution utilizing quantum dots and blockchain to confirm the creation of products and counterfeiting.

The authentication solution is blended with QDX HealthID for monitoring and tracking the mutinies of diseases, like the COVID-19. The solution validates individuals being tested, the persons conducting the test, and the test kits. 

In more simplistic terms, QDX HealthID warrants that testing data is safe and not tampered with. Recently, health reports and medical certificates are being issued on paper, which makes them simple to forge.

“Not only does this service facilitate improved health outcomes for patients, but it also underpins back-to-work certifications, sometimes referred to as immunization passports,” said Stephen B. Squires, President & CEO of QMC in a statement.

With the health data supported by blockchain, governments and health agencies can form new plans and security measures to hold the spread of COVID-19 and other diseases. Additionally, individual users can evaluate their immunization passport, utilizing a mobile application. The app highlights color-coded indicators — yellow, green, and red. If the app displays the green indicator, the individual has the authorization to interact in social and work environments. This indicator can be bestowed and authenticated by others utilizing a QR code.

“The world must have a system that eliminates the fears and anxiety of not knowing who is able to return to work,” said Les Paull, CEO of QMVT, the unit responsible for sales and marketing of QMC’s innovations in a statement. The solution is hosted on the Microsoft Azure cloud and can combine with existing EMR systems. It is based on the Hyperledger Sawtooth enterprise blockchain, and for smart contracts, it’s applying the DAML (Digital Asset Modeling Language).
