How are decentralized credit card payments possible given the amount of regulations and technical limitations?

Traditional credit and debit cards are accepted by service brokers which are hosted by Graft supernodes as network “plugins”. The supernode network is fully decentralized organization. The service broker, including credit card acceptance broker, is a distributed gateway which has an owner who complies with all necessary regulations. In addition to default “reference” implementation of credit card acceptance broker created and maintained by Graft Foundation, there will be multiple third party implementations that offer similar competitive services. Thus, technically, a single credit card acceptance broker is not fully decentralized service but it is running on decentralized, distributed, and diverse service platform.  In addition to traditional credit and debit cards, Graft is designing and implementing its own crowdfunded credit card eco-system which will be fully decentralized.
