基于区块链和ORS的电子产品追溯系统

Electronic product traceability system based on blockchain and ORS

为解决假冒伪劣电子产品以及电子产品翻新再销售等问题,建立安全、可靠、透明的追溯系统需求强烈。目前,区块链在追溯系统中具有很好的应用前景,但其自身技术存在数据爆炸新问题。对此,提出一种基于区块链和OID解析系统(OID resolution system,ORS)的电子产品追溯系统,设计链上和链下联合管理模型。链上利用区块链技术,记录电子产品的关键可追溯简要信息与详细数据的数字摘要;链下利用ORS管理大容量、详尽的可追溯数据。该管理模型解决了数据爆炸问题,实现了电子产品在供应链过程中所有信息防篡改,可追溯。通过实验测试以及与主流追溯系统对比验证了该系统的可靠性与优越性。

To solve the problems of fake and inferior electronic products and the renovation and re-sale of electronic products,there is a strong demand for establishing a safe,reliable and transparent traceability system.At present,blockchain has a good application prospect in traceability system,but its own technology has new problems of data explosion.Thus,an electronic pro-duct traceability system based on blockchain and ORS(OID resolution system)was proposed,and a combine management model on and off the chain was designed.On the chain,blockchain technology was used to record the key traceability brief information and detailed data of electronic products.Off the chain,ORS was used to manage large capacity and detailed traceability data.This management model solves the problem of data explosion and realizes that all information of electronic products in the supply chain process is tamper-proof and traceable.The reliability and superiority of this system are demonstrated through experimental tests and comparison with mainstream traceability systems.
