Shown below is the original transaction scheme proposed by JAG Electromagnetics in early 2017 for a client that had requested the development of a professional hardware wallet. This scheme was first tested with a raspberry pi zero loaded with firmware to prove that bitcoin transactions could be done by the JAG R&D team. After the proof of concept phase, JAG moved forward to the second and third phases of development and this proof of concept model was abandoned and was slated for destruction.

 

            A JAG R&D team member suggested that instead of destroying the work that had already been done in the proof of concept phase, that we should turn it into a DIY project for hobbyists and makers and give away the firmware and the use of the associated basic web application (terminal) for free. As a consequence, the DIY bitcoin hardware wallet project was born.

 

            The DIY bitcoin hardware wallet will follow the decentralized scheme as outlined below.

 

 

JAG Electromagnetics is making the following announcement: introducing the dream team (Amandeep (far left), Gabriel (top right), and Luis (bottom right))! Together we are the creators of what we believe to be the worlds 1st TRUE DIY (Do It Yourself) bitcoin hardware wallet.

Amandeep:

 

Amandeep Grewal is the Co-founder of JAG Scientific Corporation of which she is currently the CEO. JAG Scientific Corp. is mainly a think tank engineering and manufacturing outfit which operates several companies under its umbrella such as JAG Electromagnetics, JAG Space Systems, JAG Military Systems, JAG Robotics and AI Systems, JAG RF among others. Amandeep holds a BComm in Human Resources from Ryerson University and a three-year diploma from Centennial College in Business Administration. Amandeep comes to the JAG DIY Bitcoin Hardware Wallet Team with almost 20 years of experience working in the corporate sector for such companies as Wells Fargo, Hewlett Packard, and Bell Canada. She also brings invaluable experience gained as an entrepreneur in a variation of fields from aerospace to manufacturing to intelligence and tactical systems.

 

Gabriel:

 

Gabriel Santamaría is a science lover. As a Telecommunications Engineer he is always bringing together several disciplines ranging from IT and electronics to math and physics to solve problems in innovative ways.
Hardware and firmware development, wireless systems designing and low- level cryptographic algorithms development are disciplines he is merging to yield products that spread the use of blockchain technologies worldwide.

 

Luis:

 

Luis Nuñez is an Engineer geek who is constantly looking for ways to mix the mathematical and scientific analysis with computational applications and tech tools to develop creative solutions that solve technological problems. He is a curious thinker who is always seeking new challenges such as exciting blockchain applications that are highly innovative and potentially disrupting.
