Criminal activities on Blockchain (such as ransomware) have caused huge losses to society and users. The main reason for the above problem is that the strong privacy protection of the Blockchain makes criminals escape punishment. Therefore, the prerequisite for solving the above problem is that the regulator can first decide who should be punished.

In our scheme, we design a registration mechanism to enable users to register with the committee. Moreover, we add oversight measures to restrict the rights of the regulator:
