For the scenario suitable for blockchain, Jiang Hao, director of the Information Technology Department of China Everbright Bank, said that the first is the collaborative participation of multiple parties, not limited to one enterprise. The second is the alliance, and the blockchain has private, public, and alliance chains. If there is no strong lead, it is difficult to form a killer blockchain application platform for a wide range of large-scale applications. So now the blockchain is more concentrated in the field of inter-industry cooperation and industry chain, and the blockchain technology is being used locally to solve local problems. He said, "For example, in the bank high-frequency payment scenario, it is actually not suitable to use blockchain, at least at this stage. At present, banks focus on public and low-frequency businesses, such as letters of credit, as well as supply chain and asset management. Naturally, in the business field, a business scenario without a central node is more suitable for blockchain technology.
