Application And Implementation Of Blockchain Technology In Social Networks

Traditional centralized social networks face issues such as user information theft,restricted social behavior on social networks,and excessive control over users by service providers.If blockchain technology is applied in social networks,its decentralized and immutable characteristics can enable each user to hold their personal information in their own hands,not belonging to the platform.At the same time,for false information,it can be traced back to the source of the information and quickly identify the disseminators of the false information.This paper applies blockchain technology to access control,security review,and social platform design of social networks.The main research work of this paper is as follows:(1)In order to fully grasp the flow of personal information data for users and simplify the process of registering social platforms,a role-based access control method has been introduced,and feature extraction improvement has been adopted to solve the problem of system crashes caused by too many roles.And the way users apply for roles is set based on the attributes of the roles(public and private),with public roles using voting and private roles using conversation.(2)There is a lot of false information in social networks,and one of the effective ways to reduce false information is to censor the content of social platforms.Therefore,this paper designs a content security review mechanism for blockchain social platforms to conduct censorship while ensuring user freedom as much as possible.Adopt a community approach to disperse the review workload and improve the efficiency of the review,and encourage users to participate in the review work by calculating the impact and professionalism.(3)In response to the problem of centralized storage of traditional social media content,this article designs a decentralized chat platform and elaborates on the platform architecture,introduces the details of smart contract design,and displays the system interface.This platform has the advantages of non deletion and non tampering of chat content,and plays an important role in business negotiations,legal evaluations,and other scenarios.
