According to Beiguo.com, the vice president of Tencent Financial Technology Zheng Haojian believes that tax management + blockchain will produce a chemical reaction, but it promotes the tax department's transition from "vote control tax" to "technical tax control". Blockchain technology I am afraid there is still a long way to go. The application of any new technology requires time, location, and harmony. On the one hand, the maturity of the technology itself is very important; on the other hand, the technology itself is the key to the transformation of business models. Without a mature business model, the value of technology is difficult to be effectively played, it can be said that "business chooses technology."
