Internet is the basis for realization of Blockchain technology. Only if the screen is connected with Internet can it have greater value space. As X-power Chain is being applied more extensively, the sub-chains in the fields of payment settlement, copyright tracing, identification verification, advertising & marketing, DAPP open platform, etc., will establish the respective Blockchain systems. Faced with a number of settlement restrictions, the screens are isolated and the information is not communicated, which prevents it from fulfilling the value, and significantly restricts the development space of X-power Chain. On the hundred millions of public screens in the world, Internet connection can achieve the preliminary expansion of value, and connect the world. And X-power Chain is the key to achieving Internet of Things, the medicine that releases various public screens from separate, dispersed and lonely islands, and the bridge of expansion, connection and information communication between the public screens.
