智能合约技术在林果溯源中的应用研究

针对现有的农产品质量追溯系统缺乏统一标准，不能对产品供应链信息进行有效监控，产品信息可能会被恶意篡改而失去可信度等问题，本文利用智能合约构建多模块溯源模型，设计相应的用户合约函数规则，提高了追溯信息的可信度，采用以太坊结合IPFS分布式存储技术作为主要存证的底层数据库，保证了数据的安全性。最后本文以皖北特色林果为例，设计了一套林果产业链可信溯源系统，通过在企业部署运行，结果表明该系统运行可靠，溯源结果可信度高。

Application of Smart Contract Trusted Traceability in Lingou

In view of the lack of unified standards in the existing agricultural product quality traceability system, the information of the whole supply chain can not be effectively monitored, and the product information may be maliciously tampered and lose credibility. In this paper, we use smart contract to build a multi module traceability model and the corresponding user contract function rules be designed to improve the credibility of traceability information. Using Ethereum and the distributed storage technology of IPFS as the main underlying database to ensure the security of the data. Finally, taking the characteristic forest fruit of Northern Anhui Province as an example, this paper designs a reliable traceability system of forest fruit industry chain. The operation results show that the system is stable and the traceability results are credible.
