| With computer science and technology developing increasingly,while people’s quality of life has improved,the amount of data generated every day is also increasing at an exponential rate.In the era of data explosion,the potential value of data has been given careful attention to gradually with the emergence and rapid development of the technologies such as artificial intelligence and big data.Opinions on Building a Better System and Mechanism for Market-based Allocation of Factors of Production,the regulation promulgated by the Communist Party of China and the State Council in March 2020,have included data in the category of factors of production.So it can be seen that data has received the highest recognition at the national level.However,if we wish to get the full value of data,sharing is the future trend.In this thesis,we design and implement a platform for sharing and exchanging data based on block chain technology.With the use of bringing the code to the data and the help of the features of blockchain such as open and transparent,immutable and so forth,we realize the safe sharing of data on the premise that data is still in local.In our platform,the data provider,as a platform user,connects data to platform through the deployed and maintained data node.The code consumes data with controlled in a safe and trusted environment after being deployed to our platform through the capabilities provided by the platform.Data is within the control of the data provider in the whole process,and then the goal of sharing data safely is thus achieved.The main research works includes: Design from the two aspects of networking architecture and software architecture,and divide the software into several fine-grained modules.Finally,we’ll implement the platform on this basis.Test the implemented platform from the aspects of function and performance,and analyze the results of testing;Summarize our research works,and propose the defects to be improved. |
