According to the data of iiMedia research, as of August 2019, the number of blockchain projects promoted by governments around the world has reached 154, and the cumulative investment and financing scale of the global blockchain industry has reached US $10.369 billion. After ten years of development, blockchain technology has been applied in many fields, such as finance, government affairs, medical treatment, industrial manufacturing and so on, and the society's understanding of the value and applicable scenarios of blockchain has been constantly improved. The specific performance is that industrial capital returns to rationality, governments of all countries pay more attention to it, and the industry gradually moves from the barbaric growth stage to the standardized and orderly development stage. Although the blockchain industry has a broad prospect, but limited by the industry technology standard system that has not yet formed, the application and promotion of blockchain technology are subject to many restrictions. iiMedia consulting analysts believe that as the key technology of the next generation of Internet, governments and giant enterprises will increase efforts to layout the research and application of blockchain, and the competition for the right to formulate industry standards tends to be fierce. China has a good development foundation in the field of blockchain, and the number of related patent applications ranks first in the world. With the further liberalization of policies, China's blockchain industry will usher in a stage of rapid development, and it is expected to step into the first echelon of global blockchain industry in an all-round way.
