Design and Implementation of Four-Meter Reading Sharing System Based on Blockchain.

The four-meter reading refers to the unified collection and treatment of the energy data of water, electricity, gas and heat, and is a part of the national energy strategy. Although the state has already proposed four-meter reading, it has developed slowly and has little effect. The main reason is the problem of the reliability of the transmission of data in the channel and the collaboration problems caused by the industrial barriers of various energy companies. In this paper, we explore the problem of using the blockchain technology to solve the problem of the application of the four-meter reading application scenario. The research content of this paper is based on the fabric alliance chain, design data format and data management model, guarantee data security isolation, and realize a set of four-meter reading sharing system based on blockchain. For the research content of the four-meter reading scenario, firstly we investigate the knowledge of the four-meter reading application scenario, and then learn the blockchain technology and the fabric blockchain open source project. After that, the system is analyzed and designed, including requirements analysis, data isolation design, and system design. Next, the implementation of the system, including the construction of the fabric blockchain network, the preparation of smart contracts, the development of the client interface. Finally, the system is tested to verify that the system is functioning properly.
