Cheng Xiaoming, deputy chairman of the Blockchain Committee of the China Communications Industry Association, said in an interview that the Shenzhen Stock Exchange 50 Index intuitively reflects the stock market trend of listed companies related to blockchain. It can also be said that this index indirectly reflects investors' judgments on the blockchain industry. Cheng Xiaoming believes that the key now lies in breaking through the core technology of the blockchain. There are not many listed companies that are really engaged in the research and development of the core technology of the blockchain, and the core competitiveness of the technology is not particularly strong. At least there is still a big gap with the United States. Most of the listed companies are engaged in the application of blockchain. Currently, they are in the process of exploring, and they still need to strengthen their knowledge and understanding of blockchain. Note: The Shenzhen Stock Exchange has released the Shenzhen Stock Exchange 50 Index today.
