Como não pensar em Mongo

"In a world without middle men, things get more efficient in unexpected ways. A 1% transaction fee may not seem like much, but down a 15-step supply chain, it adds up. These kinds of little frictions add just enough drag on the global economy that we’re forced to stick with short supply chains and deals done by the container load, because it’s simply too inefficient to have more links in the supply chain and to work with smaller transactions. The decentralization that blockchain provides would change that, which could have huge possible impacts for economies in the developing world. Any transformation which helps small businesses compete with giants will have major global effects.

Blockchains support the formation of more complex value networks than can otherwise be supported. Normally, transaction costs and other sources of friction associated with having more vendors keeps the number of partners in a value network small. But if locating and locking in partners becomes easier, more comprehensive value networks can become profitable, even for quite small transactions."
