摘要
针对农产品供应链溯源体系中数据量庞大、多源异构、数据安全性低及区块链存储压力大、存储成本高的问题,基于区块链技术构建了农产品溯源数据多链式存储保护模型,在确保上链数据安全可靠的情况下,给供应链中各环节区块分配多个账户,以多链适应供应链各环节不同企业或厂家间的复杂交互,有效避免了溯源数据安全性低及区块链中存储压力大的问题;结合农产品供应链的溯源体系实际需求设计了追溯架构,并编写智能合约,保证了农产品供应链中各方交易的安全性与可靠性;最后,结合具体应用场景验证该模型的可行性与有效性。实验表明:该模型在数据存储安全性、交易可靠性等方面具有明显优势。
The characteristics of blockchain,such as decentralization,traceability and unforgeability,can be used to solve many problems in the traceability of agricultural products supply chain.Aiming at the problems of large amount of data,multi-source heterogeneity,low data security,high storage pressure and high storage cost in the traceability system of agricultural products supply chain,this paper constructs a multi chain storage protection model of agricultural products traceability data based on the blockchain technology.Under the condition of ensuring the security and reliability of the data on the supply chain,multiple accounts are allocated to the blocks in each link of the supply chain to adapt to the complex interaction between different enterprises or manufacturers in each link of the supply chain in the form of Multi-blockchain,effectively avoiding the problems of low security of traceability data and high storage pressure in the blockchain;combined with the actual needs of the traceability system of the agricultural supply chain,the traceability architecture is designed,and the intelligent contract is written to ensure the security and reliability of the transactions of all parties in the agricultural supply chain.Finally,the feasibility and effectiveness of the model are verified with specific application scenarios.Experiments show that the model has obvious advantages in data storage security and transaction reliability.
