China Financial Journal today published an article by the author of the Hong Kong Stock Exchange, China’s chief economist Ba Shusong, “The Blockchain Drives the Path of Financial Change”. The article points out that the current blockchain is still in the stage of rampant and barbaric growth. To truly realize the large-scale practical application in finance and other fields, it is also necessary to break through the power consumption of the consensus algorithm and the inefficiency of the P2P network model. The limit is to find the optimal solution that breaks through the blockchain "impossible triangle". Looking forward to the innovative development and technological changes of blockchain technology, it is necessary to maintain a prudent, objective, rational and pragmatic attitude.
