New Function and Configuration of Future Network for Blockchain Platform Operation

In this paper, we discuss the subnetwork structure of the Blockchain system, which is expected to develop various application platforms in the future. Blockchain is an innovative trading system, and many studies have been conducted recently. It is expected to be used in various fields with stable security function of each node taking part in the system without central server control. However, due to its three functional limitations (excessive traffic generation, lack of distributed control, and unfairness of network resources) presented in this paper, it is difficult to provide complete service in the present network. In order to minimize such problems, a subnetwork structure providing a Blockchain service should provide an appropriate network configuration according to a Blockchain application or service type. In addition, based on the number of the node participated in Blockchain and the amount of data transmitted, it is necessary to provide appropriate QoS and the subnetwork should provide stable protocol function and efficient traffic operation. This subnetwork structure is proposed as a service function of the future network structure of ISO / IEC JTC1 SC6 which is being standardized.
