Specifically, the supply chain finance is a financing mode serving upstream and downstream suppliers of a supply chain core enterprise, and the traditional supply chain finance utilizes the credit granting advantages of the core enterprise, and helps the upstream and downstream suppliers with financing difficulty to apply financing to financial institutions based on unexpired transaction accounts of the core enterprise and the suppliers, so as to purchase raw materials required for transaction with the core enterprise. And when the transaction account is expired, the supplier pays the corresponding account to the financial institution according to the contract to complete the whole financing process. The supply chain finance introduces a new financing mode by using the trust of a financial institution to a core enterprise, which is beneficial to the inventory of the supply chain and ensures that the supply chain operation mechanism is more coordinated and smooth.
However, in the conventional supply chain financial scenario, since the financial institution is based on the transaction account of the core enterprise, the supply chain financial service can only serve a small part of suppliers in the supply chain system, and a large number of second, third and fourth grade suppliers are smaller enterprises, and need to finance to maintain the operation capability of the financial institution in the supply chain. The middle-sized and small-sized enterprises are limited by the current operation situation of the enterprises, the second-level, third-level and fourth-level suppliers cannot prove the repayment capability of the enterprises and obtain good credit rating, and the financial financing of a supply chain is difficult to obtain directly through financial institutions. In addition to the qualifications, credits, of the business, whether the transaction itself is truly present is a particular concern and concern for supply chain financial providers.

and S6, after the authenticity of the receivable is confirmed, the supply chain financial service platform generates a creditor certificate according to the receivable based on the intelligent contract technology, and the owner of the creditor certificate finances the financial institution.
Specifically, referring to fig. 1, in the method for increasing credit for supply chain finance based on a block chain of the present invention, firstly, the input information of core enterprises, suppliers and financial institutions on a supply chain financial service platform may be collected and integrated, and a federation chain is constructed based on the input information and based on a block chain technology. A federation chain is a completely decentralized and independent mechanism with respect to a public chain, which is a multi-centric, multi-mechanism co-controlled block chain. The access can be realized only through authorization, and a consensus algorithm which is not proved by workload is generally adopted to improve the speed of transaction processing and have good expansibility. The characteristics of the federation chain are suitable for enterprise-level applications.
The entered information may include registration information, identity authentication information, service data information, signed platform protocol information, and the like of the core enterprise, the supplier, and the financial institution, and certainly, the entered information may also include other information, which is not described in detail in this application. By constructing a alliance chain by using a block chain technology, all members (core enterprises, suppliers, financial institutions and the like) in the alliance chain can participate in data maintenance together, and the authenticity of information uploaded by all the members is mutually proved.
The suppliers can be upstream suppliers, primary suppliers, secondary suppliers and the like, and can also comprise tertiary suppliers, quaternary suppliers and the like, and the suppliers are set according to the number of enterprises needing financing in supply chain finance. In the process of building a federation chain, registration information, authentication information, business data information, and signed platform agreement information for the core enterprise, vendor, and financial institution may be recorded in a block, as well as rights assignment information between the core enterprise, vendor, and financial institution. Then, the identity certificate information of the requester is recorded in the blockchain, and the signature information of the requester generated according to the private key is received to carry out the network joining request. The step of receiving the signature information of the requester generated according to the private key to carry out the network joining request comprises the following steps: and generating a public key and a private key of the requester according to the target asymmetric algorithm and generating signature information of the requester according to the private key and the target signature algorithm.
When the identity of the requester in the identity card information is determined to be consistent with the requester in the signature information, the requester is added among the core enterprise, the supplier and the financial institution to form a new coalition member, and the right distribution information among the requester, the core enterprise, the supplier and the financial institution is updated. And generating the next block according to the updated authority of the requester, the core enterprise, the supplier and the financial institution, and constructing the alliance chain. By constructing the alliance chain, the boundary between each member in the alliance chain is opened, and the information intercommunication of each member in the alliance chain is facilitated.
And forming N node networks according to the N nodes in the alliance chain, wherein the N node networks form N consensus nodes through a consensus mechanism, and performing consensus processing on the service data through the consensus nodes in the alliance chain. In the process, the registration information of a plurality of registered nodes in the network of N nodes can be randomly extracted, and the registration information is used as an identifier to generate a consensus representative list. The registration information includes an IP address and a MAC address. The node corresponding to one registration information in the consensus representative list is designated as an accounting node, the Hash value of the registration information in the consensus representative list is taken and published to a alliance chain, and the registration information in the consensus representative list is encrypted and sent to each node network in the consensus representative list. And the nodes in each consensus representative list decrypt the encrypted information of the consensus representative list respectively, determine whether the registration information designated as the accounting node in the consensus representative list is consistent with the decrypted registration information, and mark the registration information as the consensus node.
And dividing different node accounting authorities according to the roles corresponding to the N common identification nodes. In the process of dividing different node accounting authorities, service data of N consensus nodes are required to be obtained, and the visible authority of the service data is determined. And then, the service data is sent to the consensus nodes in each block chain, and the corresponding node accounting authority is generated according to the visible authority calculation. In the application, the node accounting authority comprises total data accounting and snapshot accounting. And in consideration of data privacy and safety, the main node in the N consensus nodes participates in consensus and carries out total data accounting, and other nodes carry out snapshot accounting. In the supply chain financial alliance chain, a core enterprise, a primary supplier and a financial institution are used as main nodes to carry out total data accounting, and an upstream supplier and a bank carry out snapshot accounting.
And then, the supply chain financial service platform generates and releases a corresponding credit amount certificate granted to the corresponding credit line by the financial institution to the core enterprise according to the corresponding node accounting authority, and records the certificate in the alliance chain. In this step, a request that the core enterprise applies for enterprise credit to the financial institution through the supply chain financial service platform can be received and executed according to the corresponding node billing authority. And then acquiring data information of the financial institution for carrying out wind control examination on the core enterprise and granting corresponding credit line. And generating and releasing the corresponding credit amount evidence to the core enterprise through the supply chain financial service platform according to the data information, and recording the corresponding credit amount evidence in the alliance chain.
And then, acquiring relevant information of accounts receivable of the core enterprise according to the evidence granted by the financial institution to the corresponding credit line, applying financing to the supply chain financial service platform by the supplier according to the accounts receivable of the core enterprise, and checking the authenticity of the accounts receivable by the core enterprise according to the transaction account information of the supply chain financial service platform.
After the authenticity of the receivable is confirmed, the supply chain financial service platform generates a creditor certificate according to the receivable based on an intelligent contract technology, and the owner of the creditor certificate finances the financial institution. All transactions are based on a federation chain formed by block chain technology, and decentralized and transparent performance of a node network in the federation determines the public transparency of all transaction information. All transaction flows are written into intelligent contracts and are determined by everyone jointly, the irreversibility and the non-tamper property of the whole process of storage, reading and execution of the intelligent contracts are achieved, all participants manage the transaction rules, and fairness is determined.
In the process, the supply chain financial service platform maintains a ledger record through the P2P network by each node together, and records the intelligent contracts in each block of the alliance chain. And simultaneously, each node is allowed to issue the intelligent contract based on the block chain, and simultaneously, contract code review service of the intelligent contract is provided. Each node can issue an intelligent contract source code, analyze the intelligent contract source code and generate a code analysis report. And according to the code analysis report, encrypting the intelligent contract by using a contract code review service, and simultaneously signing by using a private key of the intelligent contract to generate the encrypted intelligent contract. In the process, Hash operation needs to be performed on the intelligent contract, and a Hash value obtained after the operation is recorded in the alliance chain. And the encrypted intelligent contract is generated by acquiring the Hash value in the alliance chain and utilizing the private key of the alliance chain to sign. And finally, decrypting the receivable accounts in the account book record according to the intelligent contract to generate a creditor certificate, and financing the financial institution by the owner of the creditor certificate. All processes of supply chain finance are executed through intelligent contracts, and automatic execution time in the contracts expires. In a node network of a alliance chain, a monitoring node can regularly traverse the automatic execution state, the transaction and the trigger condition of each contract, automatically complete the processing of the whole transaction and state, and ensure that the whole process is transparent and cannot be tampered. And the real-time performance of the supply chain financial flow is forcibly ensured.
In summary, the supply chain financial credit-increasing method based on the block chain is beneficial to shortening the enterprise credit granting time and the creditor information verification time, reducing the cost of verifying the authenticity of information by the financial institution and the core enterprise, and facilitating the financing of second, third and fourth-level suppliers on the premise of ensuring the authenticity and reliability of data of each part.
