But why is it so useful? Take, for example, the food industry. Given the volatility of fresh produce and food in terms of diseases and health concerns, the blockchain system is perfect for it. With a more traditional system, it would be hard to keep track of the various different produce centers and farms in which food comes from, leaving a lot of risk and inability to stop a certain route if there were to be a health hazard. However, with a blockchain system, each different route is decentralized, such that companies are able to individually keep track of every single route and cut off health risks if necessary.
