This technology allows digital data to be transferred using highly sophisticated encryption and in a completely secure way. Each file is duplicated in thousands (1) nodes: any change made to this data is synchronized with the remaining copies within a few seconds, leaving a trace. To this must be added another plus, the most recent of the times in which we live: this transfer does not require a centralized intermediary (bank or Paypal) that will ensure the information.

How can it be used in healthcare?

1. Clinical data: can be read and shared in a secure way.
2. Patient: With the so-called blockchain, the patient becomes the owner of their health data. You can access them at any time (history, appointments, pains, treatments), from any place or device. Moreover, in this way, the patient will be able to share what he wants.
3. More security: With sophisticated coding, many experts believe this would be the definitive solution to maintaining complete privacy in medical history.
4. General health ecosystem: The aim is to build a suitable platform for the unification of health records.
5. Pharmaceutical industry: would allow the pharmaceutical sector to ensure health records, clinical trials, cold chain management and temperature control (vaccines) or to ensure compliance with regulations.
6. Fight against counterfeiting: Every year tens of thousands of people die in the world as a result of taking counterfeit medicines. Using blockchain would improve the traceability of the medication.
7. Accelerating R&D. With a blockchain-based analysis system, researchers can quickly gather the necessary clinical data in a verified manner.
