This issue of Key Reference publishes an article entitled Shanghai Can Learn Regulatory Experience in Block Chain Technology from Developed Countries. In addition to summarizing regulatory measures for block chain technology in foreign capital markets, the article also points out that Shanghai should actively carry out experiments on the premise of forming a safety valve. It is neccessary to actively seek application scenarios, and to timely learn and understand relevant regulatory experience from developed countries, in areas including: establishing a licensing system in the chain industry; setting up a "sandbox mechanism" for inclusive regulation; strengthening the innovation of RegTech’s regulatory technology; and stripping the “overcoat” off fake block chain projects through penetrating supervision, in order to explore the formation of Shanghai's own regulatory governance model.
