Problems solved by technology

[0003] (1) The data transaction process is complicated and the cost is too high;
[0004] (2) In the process of data sharing transactions, there are risks such as being copied, retained, and resold by a third party, so that the rights and interests of data assets cannot be guaranteed;
[0005] (3) The data transaction pricing strategy is not perfect, and there is no unified standard, which makes the data transaction rate low, resulting in a large amount of existing IoT data being idled on a large scale, resulting in a waste of resources
