Description

Blockchain-based order settlement system and method {A system for an order and settlement based on a block chain and methods thereof}

The present invention relates to an order and payment system for gold-related products, and more particularly, to a blockchain-based order payment system and a method therefor.

As of 2017, the daily amount of gold used in the precious metals market is about 500 kg, and the value of raw material gold is about 25 billion won, and the added value produced by commercialization reaches about 50 billion won. This is equivalent to the size of the domestic game market or coffee market, but the pace of development is slow due to the market structure in which domestic brands and companies cannot easily enter, and the efficiency and convenience are greatly reduced due to the conventional B2B transaction method maintained for the past 60 years. to be.

1 is a diagram for explaining an example of an existing conventional transaction method.

Conventionally, orders are received from the retail business, and orders are placed from the wholesale business to the manufacturing industry. In this case, gold is cut by the weight of the product for every order, and the gold cutting process is performed manually, and loss of real gold is unavoidable during the gold cutting process. In addition, labor costs for cutting are also additionally generated. In addition, transporting the cut gold is also run by the individual himself. Theft or loss of gold or gold products may occur during this process.

As a result, it is estimated that the annual loss at 15,000 business sites across the country is estimated to reach 150 billion won, and the time required to settle the transaction amount related to the gold transaction is 30 minutes to 1 hour per day, on average 182 hours per year It is estimated that over 350 hours are wasted.

Accordingly, there is a need to introduce a new gold trading platform encompassing B2C and B2B, and an order settlement system to support the gold transaction, breaking away from the conventional transaction method.

In the past, cryptocurrency linked to gold has been developed, but a blockchain-based order payment system for trading jewelry products has never been developed. As cryptocurrencies linked to gold, there is SNU coin, which is converted to gold by reducing card payment fees by targeting Seoul National University cafeterias and nearby shopping malls, and DGE supplied by Korea Gold Exchange. However, Snoocoin has a limitation in that the use of gold is within the university campus, and at the same time, in order to reduce card fees, payment is made after converting to gold. In addition, in the case of DGE, the gold sales price of Korea Gold Exchange Co., Ltd. is supplied at a price that is 15,000 won higher than the international market price, so it is disadvantageous in terms of price. Gold Pan (www.goldpen.co.kr) is a system that provides a special notepad function for precious metals. In the case of Gold Fan, it is difficult to use due to its complex UX/UI, and only manufacturers/wholesalers use it, so retailers and buyers (ie, consumers) cannot use it for B2C or B2B. For example, most gold fans use handwritten books and analog methods. In particular, it is only possible to manually place an order using a fax, and when ordering manually, it is used only as a notepad function to check only the details. In addition, since data cannot be traced, there are concerns about product theft in the middle of the process and difficulty in managing it, so the convenience is low.

An object of the present invention is to provide an order settlement system for direct transactions between workers by combining the problems of the current precious metals market with blockchain-based IT technology.

Another object of the present invention is to provide a method and system for order payment that reduces concerns about product theft through transparent data management in relation to gold transactions, eliminates market bubbles, and combines data mining and artificial intelligence technology.

Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings. DETAILED DESCRIPTION The detailed description set forth below in conjunction with the appended drawings is intended to describe exemplary embodiments of the present invention and is not intended to represent the only embodiments in which the present invention may be practiced.

2 is a diagram for explaining an example of a block chain-based order payment system as an embodiment of the present invention.

Referring to FIG. 2 , the order payment system may include a gold token payment unit 210 , an order ordering unit 220 , a database 230 , a wireless interface unit 240 , and a processor 250 .

The gold token payment unit 210 refers to a part or subsystem that performs payment of gold tokens in a private block chain network. The gold token payment unit 210 may generate a gold token having an exchange value of gold and a ratio of 1:N based on blockchain technology. In addition, the generated gold token may be settled based on the block chain with other peers participating in the dedicated block chain network through the payment unit 210 .

The gold token payment unit 210 may be used to support the creation and/or transaction of gold products between B2C (business-to-customer) and/or B2B (business-to-business) gold products. For example, in a B2C transaction, when a consumer wants to purchase a gold product, after first purchasing a gold token through the gold token payment unit 210 implemented in the order payment system described in the embodiments of the present invention, Gold tokens can be used to purchase gold products. In this process, unlike conventional trading methods, real gold does not need to be actually transferred between each entity. In embodiments of the present invention, gold tokens can be purchased with cash and can also be generated in exchange for participating in a dedicated blockchain channel. All entities participating in B2C and B2B transactions can be called peers.

The order placing unit 220 may perform a function for placing an order for a transaction occurring within a dedicated blockchain network.

The order placing unit 220 may be used to support the creation and/or transaction of B2B gold products. For example, it performs a function that supports transactions between retailers/wholesalers that produce, distribute and/or sell gold products or between gold suppliers and retailers/wholesalers. In this case, a retailer, a wholesaler, a gold supplier, and a gold product manufacturer may be referred to as peers or workers.

The database 230 may store information about peers participating or capable of participating in a dedicated blockchain network (eg, information about consumers, information about retailers/wholesalers, information about gold providers). . In addition, it is possible to store all information used in the order payment system described in the present invention.

The interface unit 240 provides a user interface (UI: User Interface) and user experience (UX: User eXperience) so that users who use the order payment system access and use the order payment system. For example, in order to support a B2C transaction, a link operation between the gold token payment unit 210 and an application installed in the user terminal may be supported. In addition, in order to support B2B transactions, the gold token payment unit 210 and/or the order ordering unit 220 and the application installed in the user terminal and/or the web or WAP page provided on the Internet may support a linkage operation. have.

The processor 250 performs a function of controlling the block chain-based order payment system in connection with the gold token payment unit 210 , the order placing unit 220 , the database 230 , and the wireless interface unit 240 . For example, the processor may perform an orderer function.

That is, the block chain-based order payment system used in the precious metal market described in FIG. 2 is a gold token payment unit that performs a gold token payment function within a dedicated block chain network, and orders for transactions occurring within a dedicated block chain network. Includes an order placing unit for placing an order, a database storing information on peers participating in a dedicated blockchain network, a gold token payment unit, and a wireless interface unit providing a user interface to peers in conjunction with the order placing unit can do.

In this case, when a transaction creation request is transmitted to the order placing unit through the air interface unit, the order placing unit may generate a block used in the dedicated blockchain network according to the transaction creation request and transmit it to the peers.

In embodiments of the present invention, a transaction refers to a transaction activity related to gold token remittance, product transaction, product change, and the like.

3 is a diagram for explaining a blockchain-based gold transfer process as a way in which embodiments of the present invention are implemented.

In embodiments of the present invention, when users trade gold or gold products, they do not trade real gold, but perform a transaction with gold tokens having an exchange value of 1:N with gold. Here, N is 0 and a non-negative real number. For example, N can be 0.01, 0.1 or 1. If the exchange value of gold and gold tokens is 1:1, gold token '1' has the same value as 1 g of gold. In embodiments of the present invention, the unit of the gold token is defined as 'gt' and a case having a transaction ratio of 1:1 will be described as an example. Of course, these ratios may change depending on the trading environment.

Referring back to FIG. 3 , a consumer or trader can use a blockchain-based gold transfer process by installing an application interworking with the gold token generation/transaction unit 210 of the present invention in a user terminal (eg, a smartphone). can

For example, when user A requests to create a remittance transaction through the application, the request for the remittance transaction is transmitted to a distributed application (DApp: DApp) implemented on the P2P network to support blockchain-based transactions. and the request is sent back to another peer entity. In this case, the peer entity refers to the gold token remittance target (ie, user B) and all entities subscribed to the corresponding blockchain. A remittance transaction request changes the chaincode of each peer entity and is recorded in the distributed ledger.

For example, in FIG. 3 , it is assumed that the block of the gold token before the remittance transaction request is block 9 and the block of the gold token to which the remittance transaction request is reflected is block 10 . In this case, on the distributed ledger, it is recorded in block 9 that user A's account balance is 50gt and user B's account balance is 100gt, and in the current block, block 10, user A's balance is reduced by 10gt and user B's balance is The result of increasing 10gt is recorded.

These result values are returned from the peer entity back to user A through the dapp.

4 is a diagram for explaining the flow of gold tokens as an embodiment of the present invention.

In embodiments of the present invention, a blockchain-based gold token has a value of a certain percentage relative to real 24k gold. The icon marked 24K in FIG. 4 means a gold token on the blockchain that is packed 1:1 with gold. Icons marked with Gold refer to physical gold, and the Jewelry icon refers to all tradable precious metals, including gold products made of gold.

A consumer may purchase gold from a gold supplier identified as 'A', 'B', and 'C'. In this case, gold coins may be paid to the gold supplier in return for the gold transaction. In addition, consumers can pay gold tokens in return for purchasing jewelry products from retailers.

Retailers and wholesalers can each buy physical gold by paying gold tokens to a gold supplier, and retailers can purchase jewelry products from wholesalers by paying gold tokens.

Wholesalers can pay gold tokens to purchase jewelry products from manufacturers.

That is, in addition to purchasing gold directly from a gold supplier, gold tokens may be provided in exchange for a transaction between a manufacturer of jewelry, a wholesaler of jewelry, and a retailer and a consumer. At this time, since the gold token is generated based on the block chain, the purchase history (ie, change of ownership) that occurs when purchasing jewelry between each entity can also be stored, enabling transparent transaction of jewelry.

Currently, an average of 500Kg of gold is circulated per day, and approximately 2000Kg of gold is traded. The 24k gold that flows into consumers flows to retailers, wholesalers and manufacturers. Since actual gold is currently circulated in these gold transactions, losses due to processing and cutting of gold and losses in the distribution process occur. Therefore, if the blockchain-based order settlement system described in FIG. 4 is used, the distribution of gold can be made safer and more secure. You can trade quickly and avoid losing gold.

5 is a diagram for explaining a process of exchanging a gold token and real gold in embodiments of the present invention.

Referring to FIG. 5 , user A may purchase gold tokens through the order transaction system described with reference to FIGS. 2 to 4 . For example, user A can buy gold tokens with cash, and if he has gold tokens, he can exchange the gold tokens for real gold through the order trading system. In this case, the gold token payment unit 210 associated with the order transaction system may provide a UI/UX for gold token transaction to the user A through the interface unit 240 .

In the order trading system, when real gold is purchased from the KRX gold market, the real gold is deposited in the Korea Securities Depository (KSD). In other words, the real gold is kept by the Korea Securities Depository and is withdrawn when the investor (ie, user A) wants it.

Through this, the circulation of real gold can be minimized, and each entity of the gold transaction can trade the value of gold using a gold token.

6 is a diagram for explaining an example of implementing the order payment system of the present invention as a B2C app and a B2B app.

A user may purchase a jewelry product through a B2C app (eg, a jewelry market app). At this time, the B2C app is downloaded and installed on the user terminal, and the user can purchase the desired jewelry product through the B2C app.

When a user places an order for jewelry products through the B2C app, the buyer's address, product name, size, product color, and requests are linked to the order form and an order is automatically placed through the B2B app.

In addition, a customized service based on artificial intelligence (AI) may be provided to the B2C app. There are about 15,000 offline companies in Korea, and there are also countless online companies. Therefore, the B2C app used in the present invention can recommend a jewelry product suitable for the user by learning the user's user experience by operating based on AI.

Moreover, practitioners (eg, retailers, wholesalers and/or manufacturers) can easily register/sell their products through the B2C app, and manage their jewelery products through the B2C app to manage jewelry products above a certain level. Quality can be guaranteed so that it can be distributed.

B2B apps are applications for business-to-business transactions used by retailers, wholesalers, and manufacturers. The B2B app can be composed of a worker order ordering system and a gold token payment system.

The B2B app delivers the order to the retailer, wholesaler and/or manufacturer according to the order received from the B2C app through the employee order placing system. In addition, the B2B app can control the payment according to the order to be performed using the token payment system.

In other words, the order received through the B2C app is automatically placed in the B2B app, and the transaction price according to the order is paid with blockchain-based gold tokens.

The B2B app used in the embodiments of the present invention is an order ordering system specialized for precious metals. In other words, it is a blockchain-based integrated precious metal transaction management system that conveniently provides inventory, ordering, payment and management functions with digital QR codes that are less costly compared to existing barcode machines.

In addition, the B2B app may include a blockchain-based gold token payment/transfer system. In other words, workers can trade gold through a blockchain-based gold token payment system that has improved the existing inefficient transaction method of trading real gold.

In FIG. 6 , the B2C app and token payment system are provided to a user (ie, a purchaser) in conjunction with the gold token payment unit 210 and the interface unit 240 described in FIG. 2 . In addition, the B2B app is provided to a user (ie, a worker) in conjunction with the gold token payment unit 210 , the order placing unit 220 , and the interface unit 240 .

7 is a diagram for explaining a blockchain network to which embodiments of the present invention are applied.

Part N shown in the middle part of FIG. 7 means a blockchain-based network (N: Network). In this network, an appraiser for appraisal of jewelry products (e.g., Wooshin Jewelry Appraiser, etc.) constitutes one organization (i.e., Org1; Organization), and precious metal wholesalers/retailers form one organization (i.e., Org2). The order payment system including the gold token payment unit 210 that configures and generates gold tokens constitutes one organization (ie, Org 3), and the precious metal manufacturers constitute another organization (ie, Org 4). This can be configured.

Each organization may assume that a B2C app and/or a B2B app is installed according to its purpose. In addition, the order payment system described in the embodiments of the present invention forms the basis of the block chain network, and can form a channel (C: Channel) for gold product transactions between each organization. That is, users and workers can access and use the order payment system for B2C/B2B through the channel.

On the left side of FIG. 7 , the results of the appraisal by the jewelry appraisal center and data details on the transfer of ownership for a specific jewelry product are stored in the distributed ledger of gold tokens. On the right side of Fig. 7, there is shown a table explaining each function shown in the blockchain network.

8 is a diagram for explaining a block chain-based order transaction method as an embodiment of the present invention.

In embodiments of the present invention, jewelery products are traded using gold tokens. Gold tokens are created based on a specialized blockchain mainnet for jewelry trading called Hyperledger Burrow. In addition, gold tokens are cryptocurrencies created based on a blockchain, and may have the general characteristics of cryptocurrencies. 8 is an example of jewelry, and it is assumed that diamond is traded through the order transaction method/system of the present invention.

Referring to FIG. 8 , when a jewelry product, that is, a diamond ring is traded through a block chain-based order transaction system, analysis and appraisal details of the diamond product may be stored in the distributed ledger within all gold tokens in a block chain manner. In this case, information on ownership of the DIA product may also be stored (S810).

In S810, the details of the detailed inspection to know the fingerprint image (FT-IR) of DIA can be traded in a block of gold tokens. That is, even if the 4C criteria change, the diamond identification function and value can be preserved.

In case of inquiry of jewelry appraisal and transfer of ownership to small/wholesale business in the block, the transaction details can be updated in the block of gold token. That is, when a buyer purchases a jewelry product through the B2C application, a transaction for transferring ownership of the jewelry guarantee may occur, and the inquiry block number and transaction identifier (Transaction ID) may be updated (S820). The blockchain method will be described later below.

If the jewelery product is sold again, the ownership transfer history may be transmitted to the final consumer in a block form (S830).

9 is a diagram for explaining a block chain used in embodiments of the present invention.

In FIG. 9, 'B' means a block chain, and 'Bx' means each block in the block chain. 'Hx' means the header of each block, and 'Dx' means block data stored in each block. 'Tx' means a transaction number, and 'Mx' means metadata of each block. In FIG. 9, arrows between blocks indicate that the current block is connected to the previous block.

Referring to FIG. 9 , B0 is the first block generated in the block chain, and B1, B2, and B3 mean blocks generated after each. Block data D0 included in B0 is genesis data, and T1, T2, T3, and T4 included in D1 of the next block B1 mean that a transaction occurred 4 times. D1 may store the appraisal details and/or ownership of the jewelry product together.

10 is a diagram for explaining headers and transaction information of blocks in a block chain used in embodiments of the present invention.

FIG. 10( a ) shows block 2 ( B2 ) of the block chain of FIG. 9 . The header of block 2 includes block header 2, and block header 2 includes the number (ie, identifier) of the corresponding block, the hash number (CHx) of the current block, and the hash number (PHx) of the previous block. The hash number (CH2) of the current block means a hash of current block transactions, and the hash number of the previous block means a hash number copied from the previous block.

FIG. 10( b ) shows block 1 ( B1 ) of the block chain of FIG. 9 . The block data of block 1 includes transaction 4 (T4). T4 is data indicating that the transaction has occurred for the 4th time, and includes a header indicating the unique name of the transaction. In addition, T4 includes a signature (S4), and includes P4 (Proposal) indicating the contents of the corresponding transaction. In addition, T4 includes R4 (Response) indicating the approval result of the corresponding transaction. Finally, T4 may further include verification (E4, Endorsement) details.

The blockchain described in FIGS. 9 and 10 is applied to the gold token described in the embodiments of the present invention. That is, transaction information of jewelry products is stored in the distributed ledger of each gold token.

11 is a diagram for explaining an example of a block chain network to which embodiments of the present invention are applied.

11 is a diagram for explaining the block chain network described in FIG. 7 in more detail. In FIG. 11, N represents a private blockchain network for trading jewelry products. In a dedicated blockchain network, only limited peers, that is, allowed peers, are invited to share information. Channel (C: Channel) shares data by inviting only allowed peer entities within the blockchain network. At this time, the order payment system described in FIGS. 2 to 6 may function as a channel, and the channel (C) of FIG. 11 represents a case in which P1 and P2 are invited to the blockchain network.

The orderer (O: Orderer) performs the function of sequencing the transactions that occurred in chronological order by peers and storing them as data in blocks in turn. When a block is created by the orderer, the block created through the channel is transmitted to other peers, and each peer shares and synchronizes the latest distributed ledger (L: Ledger) and has the same block chain.

11, the orderer O1 creates a block 2 (B2) containing information on transactions T1, T2, ??, and T6, and through a channel (C), peer 1 (P1) and peer 2 ( to P2). P1 and P2 create a blockchain by connecting and storing B2 to B1 in the distributed ledger, respectively.

12 is a diagram for explaining another example of a block chain network to which embodiments of the present invention are applied.

12 shows a case in which two or more data sharing channels by restricted peers exist. In this case, it is assumed that peer 1 (P1), peer 2 (P2), and orderer 4 (O4) are invited to channel 1 (C1), and P2, P3, and O4 are invited to channel 2 (C2). C1 and C2 are independent, and P2 participates in both C1 and C2.

In FIG. 12, A denotes an application, and A denotes a DApp (distributed application) and/or a client application. 'S' stands for Smart Contract. That is, 'S' performs the function of generating data to be added to the block chain by executing a smart contract. CA performs a sign function for use and verification through user authentication by supporting the private key storage function and rest API.

A case in which a transaction by P1 occurs and a transaction by P3 occurs in FIG. 12 will be described as an example. At this time, O4 creates a block for the transaction according to P1 in C1. After that, the block is shared to P1 and P2 through C1. O4 creates a block according to the transaction by P3 in C2, and the block is shared by P2 and P3. Therefore, since P2 participates in both C1 and C2, all blocks shared by C1 and C2 are stored in the distributed ledger, but P1 and P3 can only store blocks according to transactions that occur in their respective channels in the distributed ledger. have.

13 is a diagram for explaining a blockchain-based transaction process as a method in which embodiments of the present invention are implemented.

Referring to FIG. 3 , a consumer or trader may use a blockchain-based transaction process by installing an application interworking with the gold token transaction unit 210 of the present invention in a user terminal (eg, a smartphone).

For example, when user A requests to create a transaction transaction to buy jewelry through the application, the transaction is sent to a decentralized application (DApp: DApp) implemented on a P2P network to support blockchain-based transactions. A transaction request is sent, and the request is sent back to another peer entity. In this case, the peer entity refers to a gold token transaction target (ie, user B) and all entities subscribed to the corresponding blockchain. A new transaction transaction request changes the blockchain of each peer entity and is recorded in the distributed ledger.

For example, in FIG. 13 , it is assumed that the block of the gold token to which the transaction transaction request is reflected is block 10. In this case, in block 10 on the distributed ledger, user A's order management, user A's inventory management history, and user B's order acceptance result are recorded in a smart contract manner.

These result values are returned from the peer entity back to user A through the dapp.

The above-described embodiments of the present invention may be embodied in other specific forms without departing from the essential characteristics of the present invention. Accordingly, the above detailed description should not be construed as restrictive in all respects but as exemplary. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the present invention are included in the scope of the present invention. In addition, claims that are not explicitly cited in the claims may be combined to form an embodiment, or may be included as a new claim by amendment after filing.
