Evaluation on big data sharing model and key mechanism based on blockchain technology

Abstract

Due to the reliability and wide application of blockchain technology, it has attracted wide attention worldwide. Blockchain technology is widely used in finance, logistics, medicine, system management, and Bitcoin. This paper aimed to study how to analyze and study the sharing model and key mechanism of Big Data (BD) based on blockchain technology. This paper analyzed the impact of BD information resource sharing, then built an Ethernet-based BD sharing system, and tested the performance of the system. This paper also analyzed the system response time, node mining speed test, transmission speed, security and stability of Inter Planetary File System (IPFS). IPFS and blockchain Ethernet are installed on 20 hosts in Ali Cloud and Tencent Cloud servers and laboratories, respectively. The consensus mining main grid consists of 4 Windows 7 systems. In the stability test data of relevant systems, when the number of users was 20 and 100, the system stability was 99.77% and 96.93% respectively. To sum up, the system designed in this paper has certain stability and security, and is worthy of further promotion and application.
