In view of the new disputes generated in the application of blockchain posing severe challenges to the traditional remedy approaches, the international application of blockchain technology in the dispute resolution of commercial relief measures, namely blockchainbased dispute resolution mechanism. This mechanism has the advantages of decentralization of the dispute resolution system, the codification of the dispute resolution norms, and the automatic execution of the dispute resolution solution. The existing mechanisms can be roughly divided into four styles， such as infrastructure, democratic voting, similar to national courts and special services. While they bring convenience to the parties to solve disputes, they may also form “commercialized longarm jurisdiction” due to technological preoccupation, and bring hidden dangers of judicial security to the laterdeveloping countries. In this regard, China’s “blockchain+justice” should deeply develop the combination of block chain technology, and carry out a comprehensive layout of the collaborative development of the judicial and commercial dispute resolution mechanism, in order to deal with the challenge of commercial longarm jurisdiction and defend the judicial sovereignty of developing countries.
