For example, a fully functional decentralized insurance company, Airbnb, or Uber all hold great promise, and developer teams are working on similar use cases. One can think of an Airbnb or Uber as a middleman, connecting the consumer and provider of a service, and then taking a 20 to 30 percent fee for doing so. While many merchants understandably complain about credit card fees of 2 to 3 percent, the “platform fees” of Airbnb, Uber, and similar platform services are borderline egregious.
