Abstract:

In the face of increasingly complex social public opinion situations, the traditional network public opinion governance models have increasingly prominent issues such as information transmission efficiency and information security. In order to establish a new model of fair, credible, and community co-management of network public opinion governance, this article uses blockchain as a key technology for collaborative governance of network public opinion. In order to meet the requirements of network governance, the Delegated Proof-of-Stake(DPoS) algorithm is improved to solve problems. After proposing a reputation model that considers time dynamic factors, this paper constructs a reputation-based voting mechanism and rewards and punishments incentive mechanism, and also designs a new method of counting votes. From the experiment results, it was found that the node participation has increased significantly, the proportion of error nodes was obviously reduced, and the operating efficiency was improved. It shows that the improved consensus algorithm can not only improve the security of the system, reduce the possibility of false public opinion spreading, but also improve the efficiency of information processing, so it can be well applied to information sharing and public opinion governance scenarios.
