What's the Prin of Primal Building Blocks?

Block chain is a computing system where no one person is in control. It's subject to kind of consensus or votive all the participants. Everyone can see the code running, so you can build an application on four or five different things and plug them together. And then all the data is end theoretically portable. So you own it, and you can kind of take it out, or you can point it somewhere else.
