摘要:本发明公开了一种基于区块链的供应链金融防伪溯源方法,该方法利用区块链去中心化、无需第三方信任系统和具备多种加密算法等优点,在供应链金融中通过智能合约来实现,可以很好地解决传统防伪溯源方法的缺点。本发明凭借区块链自身不可篡改的特性,所有的合约内容,包括货物的状态都能够清楚地找到,解决了传统防伪溯源方法需纸质凭证转交、需第三方担保或证明机构、中小企业融资难度大、可能存在欺骗舞弊等缺点;同时本发明通过智能合约实现了买卖双方的合同约定、物流监督以及金融评估,由于一切合约均在系统中完成,所以无需纸质合约,减少了繁琐的手续,加快了进程。 |

Abstract: The invention discloses a blockchain-based supply chain financial anti-counterfeiting traceability method. The method utilizes the advantages of blockchain decentralization, no need for a third-partytrust system, multiple encryption algorithms and the like, the method is achieved through smart contracts in supply chain finance, and the defect of a traditional anti-counterfeiting traceability method can be better solved. By using the characteristic that a blockchain cannot be distorted, all of the content of the contracts including the state of goods can be clearly found, and the defects thatthe traditional anti-counterfeiting traceability method needs to be transferred by a paper certificate, a third-party guarantee or certification institution is needed, the fundraising difficulty of small and medium size enterprises is large, cheating and fraud might exist and the like are solved. Contractual agreement, logistics supervision and financial evaluation between buyers and sellers are achieved through the smart contracts, paper contracts are not needed because all of the contracts are finished in a system, complicated procedures are reduced, and the process is accelerated. | |

主权项 | 1.一种基于区块链的供应链金融防伪溯源方法,其特征在于:首先,构建由供应商、进口商、物流公司以及金融机构多方共同参与的区块链网络系统,系统成员共同存储维护两条区块链即交易链和货物链,两条链同步进行,交易链上记录有交易相关信息,货物链则记录货物及其物流信息;然后,利用智能合约实现买卖双方包括合同约定、物流监督、金融评估的操作过程,针对供应链金融中的应收账款融资模式、保兑仓融资模式和通融仓融资模式,交易链和货物链通过对智能合约进行相应调整,以适应不同的供应链金融模式;当对交易链进行相关操作时采用PBFT算法进行共识,达成共识后方可完成对交易链的签名验证操作。 | ||||||||||||||||||
