摘要
在供应链体系中,金融数据是企业能否获得融资的重要数据.然而现有的供应链体系采用中心化的管理模式,供应链中各参与方之间信息不对称,数据可能遭到篡改,如何搭建一个可信数据存证平台成了巨大的挑战.针对这一问题,提出基于区块链的供应链金融数据存证模型,为供应链各方提供可信数据.首先,结合星际文件系统对供应链金融关键数据进行链上链下存储,减轻区块链大文件存储负担,提高存储效率;其次,提出双链架构,并设计智能合约实现链上数据存储和访问;最后,在联盟链平台搭建模型,验证所提模型的有效性和效率.实验结果表明,该模型存储效率较高,适用于供应链金融数据存证场景.
In supply chain systems,financial data is critical for companies to obtain financing.However,the state-of-the-art supply chain systems adopt a centralized management model,where the information among participants in supply chains is asymmetric,and data may be attacked accordingly.It is quite challenging to build a credible data storage platform.To address this problem,a blockchain-based supply chain financial data storage model is proposed to provide credible data for all parties in the supply chain.Firstly,the inter-planetary file systems are combined to store the key data of the supply chain finance on-chain and off-chain to reduce the burden of large file storage on the blockchain and improve the storage efficiency.Secondly,a dual-chain architecture is proposed,and the smart contracts are designed to store and access data on the chain.Finally,a model on the alliance chain platform is built to verify the effectiveness and efficiency of the proposed model.Experimental results show that our proposed model has high storage efficiency and is suitable for the scenarios of supply chain financial data storage.
