It is suitable for solving the problems of insufficient transparency in the traditional social governance process and lack of trust in results, and helps to form The atmosphere of public supervision promotes the truthfulness of information from all parties, and it is also conducive to demonstrating illegal behaviors and transforming the advantages of modern science and technology into governance effectiveness.
