According to the Securities Daily News, recently, the “blockchain” is gaining momentum. On October 28th, the A-share market ushered in a comprehensive “swipe screen” of blockchain stocks. The blockchain sector index rose by 8.63% per day. Changshan North Ming and other stocks have stabilized daily limit. Peking University Finance Big Data Ph.D. Jing Jingzhen said in an interview that although the policy is to block the blockchain, the blockchain technology is not a one-step process. At present, there is no obvious change in the progress of the blockchain technology and the company's business. The policy will increase the stock price in the short-term, especially for companies that really do blockchain. At the same time, Yan Jingzhen suggested, “The blockchain has come in the future, but it must be rational. Blockchain technology is accompanied by cryptocurrencies, but blockchain technology innovation is not equal to speculation of virtual currency. Chains issue virtual currency, speculation of air currency, etc. At the same time, we must also see that the blockchain is still in the early stage of development, and needs to be further developed and improved in terms of safety, standards and supervision."
