Recently，various industries and sectors witness the application of blockchain technologies. Accompanied by disruptive innovation，the blockchain technologies bring several challenges. This is not just a security risk that may be caused by immature technologies，but also the regulatory difficulties resulting from the limitation of legal regulations and the inherent de-centralization characteristics of blockchains. For instance，it is difficult to define the boundary of legal intervention on the regulation of electronic deposit certificates. Due to the lack of a unified platform，imperfect performance and insufficient compatibility，the development of the application of blockchains is still in the primary stage.
