The Financial Times article "Big Wave Sands Global Blockchain Industry Returns to Rationality, and Countries Expedite the Exploitation of the High Ground of Emerging Technologies". The article mentioned that after the cold winter of capital in 2018, a large number of blockchain companies were eliminated, the overall industry enthusiasm declined, the capital returned to rationality, and the barbaric growth stage of the blockchain industry was nearing its end. A large number of market speculators come for wealth, and go with the wave. What remains unchanged is the core of the value of a secure, efficient, and decentralized blockchain technology. In 2019, Europe, the United States, Japan, South Korea and other countries and regions are accelerating the development of blockchain technology. China also regards blockchain technology as an important breakthrough in independent core technology, and has promoted the development of blockchain technology as a national strategy. With the continuous advancement of applications, supervision, and standardization, policy factors guiding capital and talents will once again flow into the blockchain industry track.
