I am sure that blockchain technologies will help to achieve the desired result in the fight against corona virus because with blockchain technologies any areas are developing much faster and more stable and therefore blockchain technologies will also be able to show themselves well in the fight against corona virus.
The things that i only see how blockchain technology will help to fight covid-19 is by making a online transation without using physical money because other ways to spread the virus is by passing things that was already touch by an infected person, that is why with the help of blockchain technology it will be convenient and fast for every consumer to make transactions and be safe from the virus.
That will help a lot on the financial system but that will not bring any impact to the other sector than financial sector. That's why some people may feel disagree with the tittle that has already used by the creator of this thread. Blockchain just give an alternative solution and it's not even against covid virus.
Many are yet to fully understand the usefulness and impact of blockchain technology in our society and maybe the world in general. @Blackdeath actually nailed the point. That is one area in which blockchain technology can be very useful. On the other hand, it could be futuristic. Whatever is happening now can be recorded on the blockchain, that is, the data and from such data collated, inferences can be drawn from it, which can be used to provide solution. I think the scientists and medical personnel who are researches will understand this
