I am new to blockchain. I am trying to understand the use cases of blockchain as a technology in healthcare. There are number of articles about different cryptocurrencies. I was going through this article at https://www.intelligenthq.com/innovation-management/blockchain-use-cases-in-healthcare/
I am failing to understand how blockchain would help to trace the product which is not digital.? Product, packaging material, shipping vehicles etc. everything is going to be the same. Only probably the labeling will be added with some QR codes. In this case its about identification only than why the existing solution can not work. When they say that the manufacturer produces a drug and would mark the drug with unique code, are they talking about marking each tablet or capsules.? or talking about the container/box..?
Here, if we are talking about cryptography as a solution then whats the problem with traditional cryptography solution is which is being solved by blockchain..?
