People like to claim that blockchain will sold world hunger but really it’s just a database system so unless your problem is database related blockchain isn’t going to fix it.
The problem they tried to use blockchain to fix was I don’t like the government controlling what I do with the money and knowing I commit crimes. Which isn’t really a database issue it’s a getting caught issue. If you don’t get caught you don’t need to use bitcoin and you don’t need to use blockchain.
