    摘要:

    随着水产品交易规模的扩大,区块链技术在产品溯源和数据共享方面得到广泛的应用,但不同企业内或同一供应链内的不同环节构建的区块链之间数据无法有效交互和共享,致使信息孤岛问题依然存在。因此提出了基于公证人机制的水产品跨链交易模型,旨在实现水产品不同环节之间的跨链交易,解决单点故障问题,并提升交易效率。同时针对水产品跨链交易业务特点,提出两阶段跨链交易流程,完善交易错误处理机制,从而解决跨链交易过程中的数据一致性、原子性需求,并基于Hyperledger Fabric平台构建系统原型。实验结果表明,在交易量较大的情况下,交易平均成功率高于99%,平均延迟时间为0.21s左右,模型在保证交易安全性的前提下,满足了水产品区块链跨链交易需求。

    Abstract:

    The expansion of the trading scale of aquatic products has led to the widespread application of blockchain technology in product traceability and data sharing. However, the inability of data exchange and sharing between blockchains constructed in different enterprises or different links within the same supply chain has led to the persistence of information silos. Therefore, a cros-chain transaction model for aquatic products was proposed based on a notary mechanism, aiming to achieve cross-chain transactions between different links of aquatic products, solve single point of failure problems, and enhance transaction efficiency. Meanwhile, addressing the characteristics of cross-chain transactions for aquatic products, a two-stage cross-chain transaction process was proposed, along with an improved transaction error handling mechanism, to address the requirements of data consistency and atomicity during cross-chain transactions. A system prototype was built based on the Hyperledger Fabric platform. Experimental results demonstrated that under high transaction volumes, the average success rate of transactions exceeded 99%, with an average latency of around 0.21 s. Thus, the model met the requirements of cross-chain transactions.
