I don't fully understand all the values that tokenizing the blood supply chain (sorry if my language isn't very accurate for the medical field), but I do know that many hospitals have problems with the process of supplying or requesting blood from city & national hematology centers. Data on the quantity, type, and form of blood is not really shared with everyone in that supply chain.
If we have a tracking and statistical platform for the blood supply chain, we can easily solve the optimization problem to save the lives of as many patients as possible.
