摘要
针对区块链猕猴桃溯源未考虑产业链由不同组织构成而导致溯源数据不连续的问题,结合生产实践中合同交易的过程,提出了一种面向猕猴桃质量溯源的联盟链跨组织链上合同交易机制。通过两次链上的关联确认,将现实交易中双方签字确认合同条款的过程转移到联盟链上,实现跨组织的不可否认交易。选择联盟链搭建猕猴桃全产业链溯源系统的区块链网络,借助智能合约技术将猕猴桃生产过程信息价值化;采用散列值上链减轻链上压力;通过组织间交易合同的合同编号关联溯源数据、责任人和责任企业。基于Hyperledger Fabric猕猴桃全产业链溯源系统的测试分析表明,用户每上链一条数据平均用时约102 ms,在增加链上合同交易机制的条件下系统进行一次完整溯源的时间延长了约7.11 ms。研究保证了多组织溯源的数据连续性与可追溯性,对提升农产品质量安全具有重要意义。
To solve the problem caused by the ignorance of organization-compositional diversity in blockchain-based kiw fruit traceability system,a consortium blockchain inter-organizational contract transaction mechanism for kiwi fruit quality traceability was proposed.Through two link confirmations on the blockchain,the process of signing and confirming the terms of the contract in the actual transaction was transferred to the consortium blockchain,so as to realize the cross-organization incontestable transaction.The consortium blockchain was chosen to construct the blockchain network for kiwi fruit industry chain traceability system,the smart contract technology was used to make the information of the kiwi fruit production process valuable,and the Hash value was used to light the on-blockchain stress.The transaction contract number was used to realize the association of the trace data,responsible person and responsible enterprise.Result of test analysis showed that each piece of data on the blockchain was about 102 ms.The time of one complete traceability was extended by about 7.11 ms.When on-blockchain contract transaction was increased.The research ensured the data continuity and traceability of multi-organization tracing,which was of great significance to improve the quality and safety of agricultural products.
