Dr. Chen Jianhai, head of the blockchain of the Intelligent Computing & Systems Laboratory of Zhejiang University, recently pointed out that blockchain as a new thing is really easy for people with ulterior motives to tell stories, so the government and enterprises should strengthen their studies. If you can use the blockchain technology, you can better achieve supervision in terms of information disclosure. With the blockchain, the information transmitted by the Internet is protected, traceable, and credible. Throughout the first, second and third industries, from the Internet to the Internet +, the tertiary industry has developed rapidly, and the first and second industries are relatively lagging. At present, the interconnection of the first, second and third industries is urgently needed.
