The crisis faced by crime governance in the blockchain era is mainly reflected in the following aspects: the“decentralization”of blockchain technology dispels the concept of responsibility subject,“anonymity”blocks the traditional imputation path, code automatic execution excludes the intervention of external forces in the criminal process and the“distributed”feature weakens several aspects of sovereign jurisdiction in cyberspace. The governance process of P2P online lending and online car hailing in China in recent years reveals the way to realize the harmonious coexistence between law and technology, which cannot rely on the regulatory model and the simple response mode, but should be realized through the double layered structure of law and technology on the basis of caring for each other’s core value demands. Through the dual reconstruction of law and technology, to reshape the foundation of crime governance, on the one hand, we need blockchain technology to actively maintain the existing legal regulation order and provide a technical environment for the intervention of external supervision. On the other hand, the current law should be tolerant of the“decentralization”value of blockchain technology, and establish a legal system to meet the development needs of blockchain. In addition, it is necessary to strengthen international cooperation at the legal and technical levels to reduce the negative impact of the “distributed”characteristics of small block chain on the jurisdiction of crimes on the chain.
