Every time commentator Liu Yongsheng posted "Blockchain can only create value by returning to the entity". According to the article, currently, in the fields of judicial notarization, government affairs, supply chain finance, medical treatment, public welfare, copyright protection, energy trading, etc., blockchains have corresponding landing cases, and China's central bank's legal digital currency is also steadily advancing. But in general, the blockchain is still in its infancy in enabling the physical industry, and the market's understanding of the blockchain is relatively shallow. Blockchain is not something that can be made out of nothing, and it can make money by speculation. It is a technology. Only by returning to the entity and landing in the industry can we create value.
