Block Chain and the Model Rocket Factory

Tom sacx launches a model rocket in the middle of manhattan. This is something that i was only able to do because of the block chain. What does a model rocket painted with the macdonald's logo, a us Postal service logo and bryan from family guy have to do with the block chain? I am so glad you ask. Some people think about bit coin and other crypto currencies as utopian speculative money-ish tokens; others see it as poring, intimidating and fraudulent. So who's right?
