With the rapid growth of wireless mobile networks and the proliferation of user-generated content, ensuring efficient and effective content moderation has become imperative. To ad-dress the challenges posed by the increasing workload in content moderation, along with the lack of management in third-party moderation, this paper presents a decentralized quality man-agement mechanism for content moderation in wireless mobile networks. Our approach lev-erages permissioned blockchain to establish a transparent and trustworthy infrastructure. Through the utilization of smart contracts, we automate content moderation management rules, thereby enhancing management efficiency. Our mechanism combines quality evaluation and monetary incentives based on historical authenticity data. This not only incentivizes partici-pants to consistently provide high-quality services but also ensures fairness within the system. Experimental results demonstrate the effectiveness of our approach in encouraging high-qual-ity contributions, deterring low-quality data from bad-behaved participants, and improving performance. Security analysis reveals that the cost of collusion outweighs the potential ben-efits.
