Fair And Credible Commodity Reputation Evaluation Scheme Based On Ethereum Smart Contract

The rapid development of e-commerce has effectively promoted the rapid development of online shopping activities,thus making online shopping an important part of commercial activities.In online shopping,people usually judge the quality of goods based on the display information,among which the quality information is particularly important.However,online shopping is often faced with the problem of fraud of commodity evaluation reputation,which makes the commodity evaluation reputation level displayed on the page not credible.In order to prevent users from tampering with operation evaluation data,the network evaluation environment needs to be constantly repaired and improved to ensure the availability and authenticity of commodity evaluation data.To this,a lot of businessman commodity credit appraisal plan arises at the historic moment.However,most of the traditional merchant credit evaluation schemes are based on the centralized and single commodity quality rating factors,which cannot eliminate the problems of users’ brushing,willfully tampering with the evaluation data and improving the commodity rating factors.Therefore,in an unreliable merchant credit rating network,how to fairly and impartially ensure the interests of users,the authenticity of evaluation information and online transactions has become an important research issue.Therefore,this study mainly focuses on the evaluation of commodity quality reputation and interactive fairness.The main results are as follows:(1)Aiming at the problem of reputation fraud of the commodities evaluation that is often faced by existing online shopping,an emerging blockchain technology is used to construct a fair and credible commodity reputation evaluation scheme based on Ethereum smart contracts.To the blockchain,instead of the mode of centrally hosting the commodity evaluation data on the central platform,using the characteristics of the blockchain that cannot be tampered with and decentralized,a fair and credible commodity credit evaluation scheme was designed to solve the problem of commodity reputation fraud An effective method.The new scheme can ensure the non-tampering and transparency of commodity evaluation data,and provide a credible commodity credit evaluation scheme for online fair transactions.(2)A single problem("praise","middle evaluation","bad evaluation")for the factors affecting the merchant’s product credit rating in existing online shopping.Using the anonymity and transparency of the blockchain,the decentralized storage and public verifiability of transaction data,the study constructed a decision audit plan based on the analysis of Ethereum smart contracts to determine the factors affecting the merchant’s credit rating.Ways to obtain the public’s wishes and determine the factors that affect the merchant’s credit rating that the public is more concerned about(such as refund disputes,logistics services,complaint coverage,service commitments,etc.).The interactive behavior of contract participants is recorded in the blockchain network in the form of transactions.Ensure the non-tampering and transparency of decision data.In turn,it effectively solves the problem of too single factors affecting the merchant’s credit rating,reduces the user’s transaction costs and risks,and at the same time ensures the participants’ safety and privacy protection.
