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.
