The smart era not only has a serious impact on the traditional social trust system, but also puts forward new requirements for social governance. In essence, the emergence of blockchain technology solves the discrimination in the process of information exchange in the zero-trust internet. In practice, intelligent technology represented by blockchain has become a new anti-counterfeiting verification and authorization application technology which is replaceable, convenient and safe. The application and development of this technology provides a new development idea for social governance, especially the credit system practice in the civil field, and will solve the risk of contract system in the traditional society. As a new type of data technology, blockchain has the technical characteristics of distributed decentralization, no need for credit system, immutable and data encryption security. It can play an important role in the field of social credit and have a positive impact on the development of the rule of law in the age of wisdom. Faced with the crisis of trust in social development, it is of great social significance to explore the advantages of smart contract technology application driven by blockchain technology to promote the practical application of emerging technologies. However, in the operation process of blockchain technology, there are also uncertainties in the protection of individual rights, the instability of social and economic order, and the negative effects of the construction of social credit system. The reason lies in the technical factors such as the security risk of private key, the risk of algorithm, and the limitation of basic support in the application of blockchain. In the face of the application risk of blockchain, the traditional regulation path with rigid laws and regulations as the core has obvious lag and limitations, and the emerging technologies lacking supervision will have adverse effects on social development due to the defects of their technical logic. On the basis of clarifying the technical logic and rule characteristics of blockchain, a development road of intelligent technical regulation that conforms to the development of blockchain and matches the reality of China will be constructed. This regulation path will take soft regulation as the basic idea, introduce multiple subjects to participate in blockchain governance, to achieve a high degree of unity between code governance and legal-rational governance, formal rule of law and substantive rule of law, so as to build the legal order of intelligent society, and truly play the important role of blockchain technology in data sharing, improving collaborative efficiency, building social credit system and other fields. In the specific regulation practice of blockchain technology, it is necessary to take the overall national security concept as the value basis, build a clear data governance strategy, and conduct appropriate "regulatory sandbox" experiment, so as to complete the linkage between online and offline, and build good laws and good governance of an intelligent society. Finally, the important strategic goal of high-quality rule of law construction to ensure high-quality development can be realized.
