Description

Blockchain-based export bond purchase and limit management method and a system that performs it {METHOD AND SYSTEM FOR TRADING LIMITS MANAGEMENT OF EXPORT BONDS BASED ON BLOCKCHAIN}

The present invention relates to a block chain-based export bond purchase and limit management method and a system for performing the same, and a method for processing all processes and information related to the purchase of export bonds between an exporter and a bank based on a block chain, and the same. It relates to an operating system that performs.

The e-trade system is a system that can process complex procedures and documents required in the field of trade on the network. Many trading companies and trade-related organizations use electronic documents to handle import and export business, and trade-related documents and banking services. It provides a base service that can be handled by simplifying.

In particular, in the case of purchase of export bonds among the import and export services, the purchase amount of export bonds for each bank of trading companies and the export report details of the Korea Customs Service are compared and verified in real time using EDI (Electronic Data Interchange). It aims to reduce the possibility and improve the accuracy of the data.

However, when the export bond limit management system is operated using EDI, which is a centralized system, there is a problem that the reliability of the managed information is poor.

Possibility of forgery and alteration and lack of transparency).

In addition, the export basis for the purchase of export receivables and shipping documents such as a Purchase Order, Commercial Invoice, and Bill of Landing (B/L) are submitted online/offline separately from the purchase request. However, since such information is not integrated with the purchase request details in EDI, the credibility of the data is poor (inability to prove the source of the data and lack of traceability).

In addition, since business processing according to the purchase of export receivables is managed using notifications that are transmitted and received in an electronic document method using EDI, if an error occurs in the electronic document or a situation that has not been sent is not detected, the accuracy of the limit management data Is lowered (lack of reliability).

In addition, there is a limit in managing the limit management data as each bank does not integrate the overall business, such as checking the final export performance according to the purchase of export receivables, and manually performing follow-up management such as settlement of purchase price. Lack of sex).

Accordingly, there is a need for a clear and fair export bond purchase process and a system for performing the same to overcome the problems of the conventional centralized system described above, and the present invention relates to this.

Hereinafter, a block chain-based export bond management service of the present invention will be described.

1 is a diagram showing the configuration of an export receivable management system 1000 according to an embodiment of the present invention.

Referring to FIG. 1, the export bond management system 1000 includes one exporter terminal 100, at least one bank server 200 for transacting with the corresponding exporter, and a block chain network 300. In this case, the blockchain network 300 is composed of a plurality of nodes 300A, and each node 300A may include at least one API server 400.

Exporter's terminal 100 submits a transaction to the blockchain network 300 through the API server 400, and provides various export bond-related tasks such as application for purchase of export bonds, confirmation of export report, confirmation of export bond limit, and submission of supporting documents. As a terminal of an exporter capable of performing, it may include various electronic devices such as a smart phone, a tablet PC, and a PC.

In addition, the export company terminal 100 may be installed and run the export bond application 105 that can perform the export bond business, if the exporter terminal 100 is a PC, blockchain network 300 or API server Alternatively, a web application in the form of an HTML-based universal web browser or an XML-based widget provided by a separate web server may be executed.

In addition, the export bond business request generated by the export company terminal 100 through the API server 400 is stored in the blockchain network 300, and the export bond-related business request here is an export bond purchase request and export bond purchase cancellation. It may include a request form and a request form to increase or decrease the purchase limit of export bonds.

The bank server 200 is a server device that submits a transaction to the blockchain network 300 through the API server 400, and may include a server operated by at least one trading bank transacted by an exporter. . The bank server 200 may perform an export receivable purchase receipt, purchase review, cash on delivery processing, etc. of an exporter and store it in the blockchain network 300 through the API server 400.

The blockchain network 300 may configure an environment in which the export company's terminal 100 and the bank server 200 can safely perform export receivable-related tasks, and provide services accordingly. Specifically, for this purpose, the blockchain network 300 may be composed of one or more distributed ledgers and a small number of peers in which a smart contract is implemented. In addition, in the present invention, the blockchain network 300 may be configured using the Hyperledger Fabric infrastructure, and the smart contract in the Hyperledger Fabric may be a chain code. Here, the chaincode can be implemented in Golang language, and in addition, it can be implemented in Java and Node.js languages. In addition, the blockchain network 300 of the present invention may be configured using various known blockchain infrastructures such as Hyperledger Sawtooth and R3 Corda in addition to the Hyperledger Fabric infrastructure.

The API server 400 generates a transaction corresponding to the task requested from the exporter terminal 100 and the bank server 200, submits it to the blockchain network 300, and requests the result value again. And it is a server (Server) device that delivers to the bank server 200.

So far, the configuration of the export receivable management system 1000 according to an embodiment of the present invention has been described. According to the present invention, since an exporter and a trading bank transact using the blockchain network 300, the integrity of information exchanged between the exporting company and the trading bank can be guaranteed.

Hereinafter, a method of managing the purchase and limit of export bonds using the export bond management system 1000 described above will be described.

Meanwhile, communication between the exporter terminal 100, the bank server 200, the customs clearance data server 500, the distribution company terminal 600 and the blockchain network 300 shown in FIGS. 2 to 6, that is, information Since all the receiving processes are performed through the API server 400, the API server 400 will be omitted from FIGS. 2 to 6.

2 is a diagram showing the overall work flow of the export receivable management system 1000 according to an embodiment of the present invention.

Referring to FIG. 2, an exporter (company) or exporter (individual) uses the exporter terminal 100 to prepare an export receivable business request (S101). Here, the export bond business request may include at least one of an export bond purchase request, an export bond purchase cancellation request, an export bond purchase limit increase or decrease request, and an export bond cash repayment request.

Whenever one of the export receivable business request documents mentioned in step S101 is submitted, the exporter can use the export company's terminal 100 to create a supporting document or submit it as a file such as PDF or image, and the blockchain network ( 300) can manage the supporting documents provided from the export company terminal 100 (S102-1). In addition, the'management' performed by the blockchain network 300 here is to securely store various information provided from the exporter's terminal 100 or the bank server 300 in a block, and transact changes in the corresponding information in the block. It means to constantly register.

In addition, that the blockchain network 300 processes certain information can be understood as processing any information in any one node 300A among the plurality of nodes 300A constituting the blockchain network 300. , Information may be processed through two or more nodes 300A instead of one node 300A.

On the other hand, using the export company's terminal 100, the business request created by the exporter may be continuously stored in the blockchain network, and the supporting documents may also be modified before being stored as a block of the blockchain network.

After step S102, the blockchain network 300 checks whether or not the export bond business request can be received (S103). In other words, the export receivables business request form created by the exporter is not immediately provided to the customer's bank, but an interim review is performed, which reduces the cost and time of the business processing of the customer's bank, and improves work efficiency. The business request form can be modified before the documents are processed by the customer's bank.

FIG. 3 is a flowchart illustrating step S103 shown in FIG. 2. Prior to describing FIG. 3, it is assumed that the business request created by the exporter is an export bond purchase request.

Referring to FIG. 3, after receiving the supporting documents through step S102, the blockchain network 300 can check whether the required input items are described in the export bond purchase request obtained through the exporter's terminal 100 ( S1031). For example, the required fields to be filled out in the export receivable purchase request form are customer number, purchase number, amount, contract number, payment due date, deposit account number, importer, industrial invoice number, product name, date, and personal authentication items (name, address). , Stamp), etc., may be items included in the form designated for each bank.

If mandatory input items are described in step S1031, the blockchain network 300 uses the customs clearance data server 500 operated by the Korea Customs Service to inquire the export declaration certificate information, and the export report submitted by the exporter as a supporting document. It is possible to check whether an error exists in the description (S1032, YES). For example, in addition to confirming whether the export declaration is actually a declaration through the export customs clearance procedure to the Korea Customs Service, whether the company or business entity that applied for the purchase request and the company or business entity that reported the export are the same, payment of the export declaration stated in the supporting documents. You can check whether the amount matches the amount of payment declared for export, etc.

If there is no error in the export report details in step S1032, the blockchain network 300 may check whether the export receivable balance limit of the exporter has been exceeded (S1033, YES). That is, the blockchain network 300 checks the amount of the same export receivables for all trading banks that the export company deals with, compares the balance of the same export receivables of the current exporter with the amount stated in the export receivable purchase request form, and exports You can finally check whether you can accept the bond purchase request form.

On the other hand, if the required input items are not described in S1031, there is an error in the export report details entered in the supporting documents in step S1032, or the balance limit is exceeded in step S1033, the blockchain network 300 is You can update the status of the export receivable purchase request form to'rejected'. This means that the request for purchase of export bonds requested by the exporter has not been received. The exporter can query a series of verification processes and status information checked by the blockchain network 300 through the exporter's terminal 100.

On the other hand, if the balance limit is not exceeded in step S1033, the blockchain network 300 can update the export bond purchase limit and status information of the corresponding exporter (S103-2), and query the export performance details of the exporter. Then (S103-1), the export bond purchase request can be converted into a state where it can be accepted. Accordingly, the bank server 200 may receive an export bond purchase request (S104), and the bank manager may use the blockchain network 300 to query the export performance details of the exporter.

Again, referring to FIG. 2, after S104, the bank server 200 may check whether the export bonds can be purchased (S105). That is, the bank server 200 may generate a purchase review result, and the purchase review result may be generated by inquiring a block including the supporting documents registered in the blockchain network and the export performance details of the exporter.

In this regard, FIG. 4 is a flowchart illustrating step S105 shown in FIG. 2.

Referring to FIG. 4, the bank server 200 may receive a purchase request (S104), and query the export performance details and supporting documents of an exporter managed by the blockchain network 300 (S1041). That is, the transaction bank may obtain information and documents necessary for purchase of export bonds through the blockchain network, and the inquiry details of the bank server 200 may be automatically registered in the blockchain network 300.

After step S1041, the bank server 200 may check whether the export bonds can be purchased (S105), and provide the result to the blockchain network 300.

If, as a result of the confirmation in step S105, the export bonds cannot be purchased, the blockchain network 300 may restore the export company's limit based on this information and update the status information (rejection) of the export bond business request. (S105-1, NO).

Conversely, if the export bonds can be purchased as a result of the confirmation in step S105, the bank server 200 purchases the export bonds (S105-2, YES), and the blockchain network 300 The export receivable limit can be deducted and the status information (purchase) of the export receivable business request can be updated (S105-3).

It will be described with reference to FIG. 2 again.

In step S105, if the bank server 200 determines that the purchase of the export bonds requested by the exporter is impossible, it can share that the purchase is impossible with the blockchain network 300, and the blockchain network 300 is the exporter. It is possible to return to the process of updating the corresponding export bond purchase limit and status information of (S103-2).

On the other hand, if the bank server 200 confirms that the purchase of export bonds is possible in step S105, it can be shared with the blockchain network 300 that the purchase is possible, and the block chain network 300 is the corresponding export bond of the exporter. Purchase limit and status information can be updated (S103-2)

After the export receivables are purchased, when requesting cash on delivery from the exporter's terminal 100 (S106), the bank server 200 can process cash on delivery (S107), and the blockchain network 300 is the exporter's terminal. The cash on delivery information between the 100 and the bank server 200 may be registered as a transaction for the purchase limit and status information of the export receivables of the exporter (S108). That is, each node (exporter terminal 100 and bank server 200) constituting the blockchain network 300 can check in real time that the purchase and cash repayment of export bonds has been executed.

Meanwhile, the block chain network 300 may store distribution information generated by the distribution company terminal 600 connected to the block chain network 300 in the block chain when the purchase of export bonds is executed. Specifically, when the bank server 200 receives an export bond purchase request, the status information of the export bond business request is shared to various nodes connected to the blockchain network. Information about the listed logistics can be provided. Accordingly, the bank server 200 can query the logistics processing details and results using the blockchain network without a separate request to the logistics company terminal 600, and this can be done for a certain period after the transaction is concluded.

In other words, the blockchain network 300 performs cumulative management of export documents used in the process of purchasing export bonds, adjusts the purchase limit of exporters, manages export performance, handles cash repayment, etc. After purchasing bonds, you can perform various post-managements required by exporters or trading banks.

So far, a method of purchasing export bonds using an export bond purchase block chain network using the export bond management system 1000 according to an embodiment of the present invention has been described. According to the present invention, it is possible to establish a clear and fair export bond purchase process using a block chain network, so that both exporters, banks and logistics companies can operate the trade finance system stably. You can receive benefits through trade finance.

Hereinafter, in addition to the method of purchasing export bonds using the export bond management system 1000, a method of canceling the purchase and increasing or decreasing the export bond limit of an exporter will be described.

5 is a flow chart showing a flow of a method for canceling a purchase and managing a limit in the export receivable management system 1000 according to an embodiment of the present invention.

5, the export company terminal 100 requests the bank server 200 to cancel the purchase of export bonds or increase or decrease the purchase limit of export bonds (S201). In other words, an exporter (company) or exporter (individual) can use the exporter's terminal 100 to create an export receivable purchase cancellation request form and an export receivable purchase limit increase or decrease request form. It is possible to submit the supporting documents to the blockchain network 300 using the export company terminal 100 (S202) (same as step S102 shown in FIGS. 2 to 4).

The blockchain network 300 can manage the supporting documents provided from the exporter's terminal 100 (S202-1) (same as step S102-1 shown in Figs. 2 to 4), and cancel the purchase of export bonds. It is possible to check whether required input items have been entered in the request form and the request form for increase or decrease of the purchase limit of export bonds (S203). This is a process of checking whether an export receivable purchase cancellation request and an export receivable purchase limit increase or decrease request form can be received by the bank server 200. Required input items include, for example, customer number, purchase number, amount, contract number, deposit maturity date, and deposit account. Number, importer, industrial invoice number, product name, date, personal authentication items (name, address, seal), etc., may be items included in the form designated for each bank.

If it is confirmed that the required items have been entered in step S203, the blockchain network 300 registers the request as a block of the blockchain network, and the bank server 200 receives an application for cancellation of purchase or an increase or decrease in the purchase limit of export bonds. Do (S204, YES).

After step S204, the bank server 200 can check whether a request for cancellation of purchase or an application for an increase or decrease in the purchase limit of export bonds is possible (S205). The purchase limit and status information can be maintained as it is (S205-1, NO).

On the other hand, as a result of the confirmation in step S205, if an application for cancellation of purchase or an application for an increase or decrease in the purchase limit of export bonds is possible, the bank server 200 cancels the purchase of export bonds or increases or decreases the purchase limit of export bonds by the exporter (S206, YES). , The blockchain network 300 may update the purchase limit and status information of the export receivables of the exporter according to the purchase cancellation or the increase or decrease of the limit (S206-1).

So far, a method of canceling the purchase of export bonds and managing the purchase limit by using the export bond management system 1000 according to an embodiment of the present invention has been described. According to the present invention, the export company can check the status of purchase business processing, the integration limit, etc. in real time, and request correction, thereby preventing a situation in which the purchase limit is exceeded or duplicate purchases are made.

6 is a diagram illustrating a business processing area performed by components in the export receivable management system 1000 according to an embodiment of the present invention.

Referring to FIG. 6, the exporter is through the exporter's terminal 100 connected to the blockchain network 300: ① request for purchase of export bonds, ② inquiry result of the application, ③ inquiry result of purchase, ⑤ limit adjustment processing, ⑥ cash repayment processing. Through the bank server 200 connected to the blockchain network, the bank can perform ② request for purchase of export bonds, search and download supporting documents, search for export performance, ③ share purchase results, ④ search logistic details, ⑤ limit Adjustment processing, ⑥ cash on delivery processing can be performed, and logistics companies that transact with export companies can share ④ logistics details through the logistics company terminal 600 connected to the blockchain network 300, and the blockchain network 300 ) Through the customs clearance data server 500, ② can check the export report details and query the export performance.

Here, the blockchain network 300 builds an export bond purchase and limit management platform, and provides information provided by the exporter terminal 100, the bank server 200, the customs clearance data server 500, and the logistics company terminal 600. Can be processed as a transaction. Accordingly, the blockchain network 300 checks the export report details at the request of the exporter's terminal 100, inquires information on export performance, manages supporting documents, or processes the bond price after purchasing export bonds. It can provide services that can be done, and at the request of the bank server 200, verify the export receivable limit of the exporter, check the export report details, provide supporting documents, provide logistics details, or export receivables. A service capable of processing payment may be provided, and the logistic details provided by the logistic company terminal 600 may be shared with the exporter's terminal 100 and the bank server 200.
