Quite a few folks still are not sure whether bitcoin and its blockchain platform add value. They as “What can one do with them?” The answer is not so simple because the uses that will become rather commonplace in the future have not been created yet.
So what CAN we say? One thing we can say is that blockcains will have a variety of uses in connection with something called “supply chains”. We don’t think much about supply chains now because we don’t have anyway to discover them. We buy products all the time without knowing where they or their components were produced and how.
But supply chains matter. Food is a good example. We don’t think about where it comes from until we find out that a supply source is contaminated, like with mad cow or avian flu. Then we care a lot. And if we knew more about supply chains, we could use that information lots of ways. Here is a nice post with some scenarios.
