Abstract [en]

With the advent of big data era, there is countless data produced from various kinds of machines every second. These data are used to help people to do studies, produce goods, improve the efficiency of the industrial development, and so on. Especially considering the Internet of things which connects all the smart machines together, the importance of data integrity gets unprecedented attention from us. In order to keep the data integrity, blockchain comes to its birth using its own structure to guarantee the data integrity efficiently. This project is focus on the simulation of data system based on the blockchain in the background of industrial internet of things which is shown in a form of a website with coding language jade and the environment is Node.Js. The main task is to measure the time consumed in the process of block mining under different parameters include data length, nonce, difficulty, sensor number in order to find the correlation between block mining time and different parameters. Thus, the rule about the impact of different parameter on the mining time are concluded. According to the rule I found, the evaluation about scalability, efficiency and safety of this system are given and I also summarize two formulas to calculate the efficiency of block mining. Ethical consideration and future work are addressed in the conclusion part.
