The birth of the blockchain marked the beginning of the construction of a truly trustworthy Internet. By combing through the rise and development of the blockchain, it can be found that the focus of the blockchain is that it can establish a reliable peerto-peer trust in the network, so that the value transfer process removes the interference of the intermediary, which not only discloses information but also protects privacy , Both making joint decision-making and protecting individual rights and interests. This mechanism improves the efficiency of value interaction and reduces costs. From an economic point of view, the new value interaction paradigm created by the blockchain is based on "weak centralization", but this does not mean the complete disappearance of various "centers" in the traditional society, and a large number of blockchains will appear in the future.
