U.S.-based quantum dot producer Quantum Materials Corp (QMC)
announced its blockchain-based QDX HealthID for transparency
in disease testing and immunization for infectious diseases.
The goal is to ensure the
authenticity of health data and support individuals to re-join the
Quantum dots are nanoparticles made up of semiconductor
materials that emit different colors when illuminated by light. This
color depends on their size and the way they were manufactured.
QMC has developed a track
and trace solution using quantum dots and blockchain to verify the
origin of products and counterfeiting.
The authentication solution is combined with QDX HealthID for
monitoring and tracking the outbreaks of diseases, such as the
COVID-19. The solution authenticates individuals being tested, the
persons administering the test, and the test kits.
In simpler terms, QDX HealthID ensures that testing data is secure
and not tampered with.
Currently, health reports
and medical certificates are being issued on paper, which makes them
easy 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.
With the health data
backed by blockchain, governments and health agencies can formulate
new plans and safety measures to contain the spread of
COVID-19 and other diseases.
users can assess their immunization passport using a mobile
The app features
color-coded indicators - green, yellow,
If the app shows the
green indicator, the individual has clearance to interact in social
and work environments.
This indicator can be
shared and authenticated by others using 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.
The solution is hosted on
the Microsoft Azure cloud and can integrate with existing EMR
It is based on the
Hyperledger Sawtooth enterprise blockchain and for smart
contracts, it's using the Digital Asset Modeling Language (DAML).
Yesterday, Ledger Insights reported on the COVID
Credentials initiative (CCI), which uses digital identity to
develop "immunity passports".
