Is Block Chain Enabler of Commerce?

i suspect you will see it very soon, because it's logical for them to extend their reach. Why have we not seen a move from amazon, google and ei? Think only because they haven't decided what their strategy is going to be. And i don't see block chain as an existential threat to those businesses per se. It's just a more secure version of the same thing. So i think that would be logi extension, for example, for apple. And the same thing goes forAmazon to enable peer to peer transactions.
