According to the North China Network, recently, at the 2019 China International E-Commerce Expo, Zhu Jiang, head of the block chain of Jinshan Cloud District, said that the application of blockchain technology has entered a new development cycle, which is highlighted in policy orientation, technology awareness and Industrial applications will surely play an increasingly important role in the new round of digital economy. He also pointed out that blockchain, as a trusted public infrastructure-level technology, will play a major role in the new round of digital economy. In this tide, technology participants are no longer between enterprises and enterprises. Business contacts are measurement units, but they will achieve symbiosis with industry chains and industrial groups. Technology is important, but the decision to win or lose requires a chain of economic vision in the new financial situation. "Technology + industrial application" can make the blockchain more valuable.
