Design And Implementation Of Social Platform Based On Blockchain

At the present stage in China,common network social channels include:social networking sites,blogs,microblogs,WeChat,video sites,forums and podcasts,among which WeChat and social networking sites have the largest number of users.However,people are living in an era of information and data as the center,the public's reliance on social media is gradually increasing,at the same time,the threat of social media to the public information security is also on the rise.But social media exposes many layers of problems.For example,users' personal information was stolen by hackers,the system went down,the personal information released by users on social platforms was excessively commercialized,and the intellectual property rights of published articles were not protected.In recent years,with the popularity of Bitcoin,Blockchain technology has entered people's attention.Blockchain technology is known for its privacy and decentralization.This paper is based on the existing problems of the centralized social platform,combined with the characteristics of block chain technology,design and implement the system.Blockchain network uses P2P to communicate,and data synchronization is completed through consensus mechanism.Each client is a hub,again through a consensus mechanism to prevent users from tampering with data.At the same time,valuable information should be recommended and get some benefits,while worthless or bad influence information should be low quality or even deleted.Writing a Solidity contract for Ethereum(ETH)to implement the main features of the social system,and writing a token contract to use as an incentive for the platform to send users.In this way,while realizing the decentralization of the social platform,users are encouraged to provide valuable information and protect their privacy.After the completion of the system performance and function testing,and analysis of the test results.The social platform realized in this paper has the characteristics of decentralization,which can prevent the commercialization of user data,minimize the platform permissions,and reward and punish users for their participation.
