Shuai Chu, the founder of quantum chain, said: at present, the evolution of the whole blockchain technology is still at an early stage, just like the Internet era 20 years ago. At that time, we could not imagine that there would be applications like Uber on the Internet. The development of technology would give you more diversity. The possibility is the future

According to the technical characteristics of blockchain, Zeng Ming, Dean of Hupan University, gave several possible answers:

1. The most important advantage of blockchain is transparent, unchangeable and distributed ledger. Some areas have never been covered by the Internet, such as acceptance bills

2. Another big advantage of blockchain is that from the perspective of smart contract, it is possible to form more efficient network collaboration at the point-to-point level. Like crowdfunding

Therefore, in the stock market operation before 1995, the biggest bad news is usually the news that the pilot of China's stock market will stop and the stock market will close

later, affected by the "3.27 treasury bond futures incident", China's futures market carried out a comprehensive rectification in 1995, and China's stock market became the object of support, so that the stock market ushered in a real positive and turned into a period of great development
