摘　　要：区块链技术在跨境电商商品拍卖行业的应用越来越广泛,但是存在不能全部隐藏投标人拍卖商的身份信息,不能对参与者进行细粒度控制管理,拍卖过程机械呆板和扩展性难等问题。拍卖商使用细粒度控制的区块链跨境电子商务的商品拍卖模型,可以对投标用户设置细粒度参与权限的准入机制,确保供应商的准确性,实现恶意投标人可追责,保证其出价的机密性。实验从检验算法开销、单笔交易各阶段操作Gas消耗和认证花费时间三方面进行验证,拍卖过程新增细粒度过程控制机制,使得拍卖交易过程更加灵活,也保护了各方的隐私。Blockchain technology is increasingly widely used in the cross-border e-commerce commodity auction industry,but there are problems such as not being able to fully hide the identity information of bidders and auctioneers,not being able to perform granular control and management on participants,and the auction process being mechanical and difficult to expand.Auctioneers use a fine-grained controlled blockchain cross-border e-commerce product auction model,which can set a fine-grained access mechanism for bidding users to participate in,ensuring the accuracy of suppliers,achieving accountability for malicious bidders,and ensuring the confidentiality of their bids.The experiment verifies from three aspects:the cost of testing the algorithm,the cost of operating Gas at each stage of a single transaction,and the time spent on authentication.The addition of a fine-grained process control mechanism to the auction process makes the auction transaction process more flexible and protects the privacy of all parties.
