COVID-19 data sharing and organization through blockchain and decentralized models

The pandemic due to Covid-19 has highlighted and sometimes amplified some critical issues affecting the global health system. From the beginning, it was clear that having an overview of the pandemic situation was one of the main objectives to be achieved to fight the Virus. In this sense, technologies based on decentralized systems, such as Blockchain, can be effective in collecting data since they can store information in a secure and scalable way while respecting people's privacy. This work aims to propose a framework based entirely on decentralized systems that can solve management and collaborative analysis of sensitive data, such as those related to the Coronavirus pandemic. In particular, the model is proposed as a tool to improve the efficiency of all those organizations that have found themselves on the front line to deal with the spread of the Virus in the world, such as hospitals and research institutes. In addition, it aims to improve communications between organizations at the global level to facilitate a fair and profitable exchange of knowledge to fight the pandemic.
