摘　　要：传统社区式问答平台中问答数据不仅透明度低而且容易被内部员工或外部攻击者篡改,导致客户无法信任问答平台信息的真实性,同时,因激励机制的缺乏也让已购买客户没有动力回答其他消费者的提问。为了改善现状,提出并设计一种基于区块链智能合约的社区式问答服务平台,此平台引入了随机邀请、积分激励和声誉激励机制。该平台主要由6个智能合约协同工作,完成用户注册、产品上架以及交易、授权、提问、回答和评分等功能,同时在链下使用基于Minhash和Jaccard算法的文本相似度检测方案,提升用户回答的多样性。在以太坊私链环境中对Solidity语言编写的智能合约进行测试和分析,试验结果证明了代码的正确性和方案的有效性。In the traditional community-based Q&A platform,its Q&A data was not only low in transparency,but also vulnerable to tampering by internal employees or external attackers,resulting in customers not being able to trust the authenticity of information such as the identity of the respondent who had purchased and the ranking of the answers,while at the same time,the lack of incentive mechanism also made customers not motivated to answer other consumers′questions.In order to improve the current situation,a community-based Q&A service platform was proposed,which introducedthe mechanism of random invitation,point incentive and reputation incentive.The platform was consisted of six smart contracts working together to complete user registration,product shelving,and functions such as trading,authorization,questioning,answering and scoring,while the text similarity detection scheme based on Minhash and Jaccard algorithm was used under the chain to improve the diversity of user answers.The smart contract was tested for functionality and performance analysis in an Ethereum private chain environment,and the experimental results proved the correctness of the code and the effectiveness of the scheme.
