Shen Jianguang, vice president of Jingdong Group and chief economist of Jingdong Digital Technology, said in an interview that, in general, the development of blockchain has focused on digital currencies from the early days, and now pays more attention to the completeness of technology and its use in digital Bills, product traceability and other applications in many industries and fields. Therefore, from the perspective of the development prospects and future trends of the blockchain, the development of the blockchain technology is expected to make a new batch of entrepreneurial enterprises emerge as the times require, and promote the independent innovation and industrial application of the technology, especially in the current manufacturing industry is moving towards intelligence. In the process of specialization and efficiency upgrade, the application space of blockchain will be further enlarged. Shen Jianguang further pointed out that the four major applications of blockchain in the manufacturing industry are: connecting distributed manufacturing resources, enabling asset lifecycle management, ensuring end-to-end additive manufacturing (AM) processes, and increasing visibility of the supply chain. . For example, traceability of product manufacturing, combined with blockchain technology, producers can pass the raw material supplier of each product, the entire processing process flow, quality information, processing equipment number and other information through the blockchain, the entire supply Each unit on the chain can understand the actual operating status of each branch factory. However, it should be noted that the application of blockchain in the manufacturing industry is not a one-man show. It also involves data analysis and capture of equipment production data and processing parameters. It also requires the comprehensive use of big data, cloud computing, and Technologies such as the Internet of Things. This also reflects a characteristic of blockchain applications, that is, the integration and use with other digital technologies will be the mega trend and the general direction.
