Description

A kind of anti-fake source tracing method of supply chain finance based on block chain
Technical field
The invention belongs to supply chain finance and block chain technical fields, and in particular to a kind of supply chain gold based on block chain Melt anti-fake source tracing method.
Background technology
Supply chain refers to that former material expects whole process of the intermediate products to final products to sales network to consumer, be by The compositions such as supplier, manufacturer, retail trader, retailer.And supply chain is financial, then is to add bank and P2P investment platforms, Around a kind of financial market that supply chain core enterprise is established, supply chain finance has following Three models:
Financing by accounts receivable pattern:Supplier is based on the sales contract really generated with demand client, with trade Accounts receivable is financed as effective refund source to bank or P2P platforms.
Confirm storehouse Financing Mode:It is taken in and the repurchase of supplier and the delivery of cargo of cargo into trader with selling gained after stocking up Based on power and refund source is financed to bank or P2P platforms.
Get around regulations storehouse Financing Mode:Bank or P2P platforms commission logistics corporate supervision supplier cargo, while to cargo into Row valuation, and using valuation as standard come to supplier invest, supplier promise to undertake to cargo repurchase or it is overdue directly by financial machine Structure is sold.
From above-mentioned supply chain financial models can be seen that existing supply chain finance anti-fake source tracing method have it is following heavy Want link:1. the seller and the papery contract of buyer;2. the supervision information of logistics company;3. the assessment of financial institution oneself;4. it buys It sells, the multi-party agreement reached jointly such as logistics and finance.Therefore, existing anti-fake source tracing method has following drawback:
1) a large amount of paper material is needed, it is either certainly still anti-fake to both increase workload and difficulty.
2) it needs to introduce third party guarantees or certifying authority.
3) it establishes on the prestige and fame and prestige of core enterprise, increases Financing difficulty.
4) since the process assured, supervise, assessed is personnel's operation, so being difficult to avoid that the hair that personnel gang up, practice fraud It is raw.
Invention content
In view of above-mentioned, the present invention provides a kind of anti-fake source tracing methods of supply chain finance based on block chain, utilize area The advantages that multiple encryption algorithms, can not be distorted and be had to the decentralization of block chain without third party's belief system, block, in supply chain The shortcomings that being realized in finance by intelligent contract, traditional anti-fake source tracing method can be well solved.
A kind of anti-fake source tracing method of supply chain finance based on block chain, it is as follows:
First, it builds by the block chain network of supplier, importer, logistics company and financial institution's multiparty System, two block chain, that is, chain transactions of the common storage system maintenance of DBMS member and Goods Chain, two chains, which synchronize, to carry out, and remembers on chain transaction Record has transaction related information, and Goods Chain then records cargo and its logistics information;
Then, realize that both parties include contract engagement, logistics supervision, finance assessment etc. and operated using intelligent contract Journey, in supply chain finance financing by accounts receivable pattern, confirmation storehouse Financing Mode and get around regulations storehouse Financing Mode, chain transaction and Goods Chain is by adjusting accordingly intelligent contract, to adapt to different supply chain financial models;When to chain transaction progress phase It is carried out when closing operation using PBFT (Practical Byzantine Fault Tolerance, practical Byzantine failure tolerance) algorithm Common recognition, can complete the signature verification operations to chain transaction after reaching common understanding.
Further, the Goods Chain is not artificially controlled, and each cargo list information changes only by the intelligence on chain transaction Energy contract triggering, automatic decision condition are simultaneously completed.
Further, the flow for signing intelligent contract simultaneously with both sides on the chain transaction carries out, and there is no independent structures The flow of block is built, and avoids the generation of fakement phenomena to the maximum extent by game theory principle.
Further, whether all intelligent contracts on the chain transaction will carry out the contract of preamble bit by system It completes, the whether qualified dual judgement of cargo state, only when two conditions are satisfied by, a contract can be led to It crosses and charges in chain.
Whether the contract that further, all intelligent contracts on the chain transaction will carry out preamble bit completed, The whether qualified dual judgement of cargo state, only when two conditions are satisfied by, a contract can be by by simultaneously It charges in chain.
The characteristic that the present invention itself can not be distorted by block chain, all treaty contents, the state including cargo can It is enough clearly found, solving the anti-fake source tracing method of tradition needs papery voucher to deliver, need third party guarantees or certifying authority, is medium and small Corporate finance difficulty is big, there may be the shortcomings of deception malpractices;The present invention realizes both parties by intelligent contract simultaneously Contract engagement, logistics supervision and finance assessment, since all contracts are completed in systems, so without papery contract, subtract Elaborate formalities is lacked, has accelerated process, specific advantage is as follows:
(1) without a large amount of paper material;
(2) without third-party monitoring, guarantee agency, due to the property that block chain can not be distorted, all contracts all can be by It records, then tracing to the source and calling to account can be realized by block chain, without the third-party institution;
(3) popularity and prestige of core enterprise are needed not rely on, the confidence level of all intelligent contracts has been in block chain Exactly the same;
(4) since intelligent contract needs all users to pass through, and verified by computerized algorithm, can not human intervention, institute It is not present taking human as wash sale is carried out.
