On November 6th, at the 3rd China-Singapore Forum, Huang Zhangkai, an associate professor at the School of Economics and Management at Tsinghua University, said that whether it is to increase the development of blockchain or to develop artificial intelligence technology for financial services, the ultimate goal should be to serve The real economy. In Huang Zhangkai's view, blockchains naturally carry monetary and financial attributes, so many financial institutions are very concerned about this technology. For example, he said that for financial institutions, blockchain technology has greatly promoted supply chain financing, trade financing, and cross-border trade financing. At the same time, he also pointed out that the blockchain system is not only the information flow, but also the flow of funds itself, which helps small and medium-sized enterprises solve the financing difficulties, and can also help them to deeply participate in international trade. However, Huang Zhangkai stressed that because the monetary and financial attributes of the blockchain lead to inevitable bubbles or speculation, it requires the timely participation of governments, innovative management methods, and the development of a sound regulatory system that cannot be repeated in other areas. The situation of chaos, death and death."
