I agree that blockchain could help in combatting fake medicines, but the question remains - will the government actually start doing it?
It surely is possible in any sphere. Devery is a project that wants to combat fake goods, for instance.
As for people who said that India banned cryptos, they are wrong. India's national bank said they don't recognize them, but the bank has to right to make such things as banning cryptos. This has to be done by the officials. That's why perhaps they are trying to show that they disagree with the national bank and actually want to show how useful blockchain technology can be. It can indeed solve many problems related to fake products and pretty much anything else where authenticity is of great importance.
