Blockchain-based product trading system {COMMODITIES TRADING SYSTEM BASED ON BLOCKCHAIN}

The present invention relates to a blockchain-based product trading system. More specifically, product trading that can provide information about distributed products transparently and fairly using NFT (Non-fungible Token) using blockchain technology. It's about the system.

As the size of the online transaction market grows, not only B2C, which was the basis of e-commerce, but also C2C-based transactions are growing rapidly. As information technology develops, the online transaction market is gradually becoming globalized and expanding in size, and is expected to have a significant social and economic impact.

Meanwhile, since online transactions are conducted non-face-to-face due to the nature of the transaction, they are carried out depending on mutual trust in the transaction counterparty, but mutual trust is difficult to achieve.

To solve these problems, various types of security functions are applied to online trading platforms, but complex problems, including fraud cases, continue to occur due to incomplete systems. For example, the safe transaction system applied in used trading platforms can solve the Internet fraud problem to some extent, but the actual usage rate is low due to the high commission rate.

Therefore, there is a need to build a product trading system that can be easily applied to online trading platforms and allows both sellers and buyers to trade products safely and at a reasonable price.

The present invention is intended to solve the problems of the prior art as described above. The purpose of the present invention is to provide a product trading system using blockchain that can promote transparent transactions by providing information about products and transactions online to sellers and buyers. It is intended to provide.

Another purpose of the present invention is to provide a product trading system that can calculate and provide reasonable prices for traded products based on product transaction profiles.

One aspect of the present invention to achieve the above purpose is a product trading system using blockchain and NFT (Non-fungible Token), where users who sell and purchase products collect the data necessary for selling and purchasing products. It is configured to include: a user terminal for transmitting and receiving; and a service server that mediates product transactions of the users, wherein the service server includes: a product register where a user registers information about a product; An NFT generator that creates a product profile using the registered product information, generates an NFT for the product based on the product profile, and registers the generated NFT in a blockchain; A product trading department that brokers product transactions for users based on the NFT; and a product certification unit that provides product proof of the validity of the product and transaction proof of the validity of the transaction.

In the blockchain-based product trading system according to an embodiment of the present invention, the product profile includes product name, product identification number, manufacturer, manufacturing date, purchase date, purchase price, and buyer unique identification information (UUID). It could be.

In addition, the product transaction department includes buyer unique identification information, seller unique identification information, sale date, sale price, and transaction method. This may be to create a transaction profile that is created and updated every time a transaction for the same product occurs.

In addition, the service server updates the NFT for the product based on the generated transaction profile, and the updated NFT may be shared through blockchain.

Additionally, blockchains for similar products may be composed of connections to the same blockchain.

In addition, when updating the NFT, the service server may generate an updated NFT including the average transaction price information generated by calculating the average transaction price of the same product from NFT information shared on the blockchain.

Additionally, the average transaction information may be calculated by reflecting a time weight that is inversely proportional to the time elapsed from the transaction time.

In addition, the price evaluation unit may calculate appropriate price information from the average price information, and the appropriate price information may be calculated by reflecting the weight of the depreciation factor of the product in the average price.

Additionally, the depreciation factor may be comprised of the period of use and number of transactions of the product.

In addition, the product certification unit may perform verification of transaction validity and product validity based on the transaction profile and product profile.

Additionally, the product trading department may mediate product transactions through an escrow service.

And, product trading by the product trading department includes: (A) the seller registering the product for sale on the service server; (B) A step where the buyer purchases an NFT for the product registered for sale and pays the cost for the purchased product to the system; (C) Processing the NFT and payment through a third party escrow service; (D) providing shipping information of the product by the seller to the buyer through the service server; (E) the buyer receiving product shipment information and requesting payment from the system; And (F) paying the fee to the seller in the system and transferring NFT ownership to the buyer.

In addition, if a product with the same unique identification information as the existing product profile is registered for sale, and the final owner and the product sales registrant on the NFT of the product do not match, the service server provides the unique identification information of the product registered for sale. It may be determined whether it matches the unique identification information of the product for which transaction suspension has been requested, and if transaction suspension for the product is requested, an arbitration protocol may be executed.

And, the arbitration protocol includes the steps of: (A1) the service server creates a virtual buyer profile and approves the sales registration; (B1) generating virtual deposit information of the virtual buyer for the product registered for sale; (C1) providing the virtual deposit information to the seller; (D1) When information on the shipment of the corresponding product by the seller is received by the service server, the service server transmits to the seller and the final owner of the NFT of the product that the arbitration protocol process for the product is in progress; It may be carried out including.

The blockchain-based product trading system according to the present invention has the effect of providing information about distributed products transparently and fairly using NFT using blockchain technology.

In particular, according to the present invention, it is possible to induce a fair trading relationship by enabling the source of the product, product proof, confirmation of ownership, and sharing of the transaction amount through product verification through the product profile and transaction verification through the transaction profile. It works.

In addition, it has the effect of inducing a reasonable transaction relationship by calculating and providing appropriate prices for traded products based on transaction history using blockchain.

Furthermore, through NFT, safe transactions can be encouraged through product ownership and escrow services, accidents such as theft and fraud can be prevented, and the damage to theft victims can be substantially relieved by conducting arbitration for stolen items. There is an effect.

The present invention basically relates to a product trading system that can provide information about distributed products transparently and fairly using NFT (Non-fungible Token) using blockchain technology.

Hereinafter, the blockchain-based product trading system of the present invention will be described in more detail with reference to a preferred implementation example and the attached drawings. In this regard, Figure 1 is a block diagram of a blockchain-based product trading system according to the present invention, Figure 2 is a relationship diagram showing the relationship in which NFTs are created by the system of the present invention, and Figure 3 is a system of the present invention. This is a flowchart showing the order in which product transactions are performed.

First, referring to Figure 1, the blockchain-based product trading system of the present invention largely includes user terminals 100 and 300 for users selling and purchasing products to transmit and receive data necessary for selling and purchasing products, and the users' It may be configured to include a service server 200 that mediates product transactions.

The user terminals 100 and 300 are devices for the user to request a service from the service server 200 and use the service provided by the server. The user terminals 100 and 300 can be divided into a seller terminal 100 owned by a person who sells a product and a buyer terminal 300 owned by a person who purchases the product. Examples of the user terminals 100 and 300 include, but are not limited to, a PC (Personal Computer) or a mobile phone, and may include various communication devices that can be connected to the service operator's server through a wired/wireless communication network. there is.

In the present invention, the service server 200 is a part where the service provider mediates product transactions among users and stores and updates various data related to product transactions. The service server 200 creates a product register 210 in which a user registers information about a product, a product profile 410 using the registered product information, and based on the product profile 410. An NFT generation unit 220 that generates an NFT for a product and registers the generated NFT in the blockchain 400, a product trading unit 230 that mediates users' product transactions based on the NFT, and It may be configured to include a product certification unit 240 that provides product certification for the validity of the product and transaction certification for the validity of the transaction.

In the present invention, the product registration unit 210 is a part where the seller registers the product he or she wishes to sell. When a seller registers a product in the product register, the NFT generator 220 creates a product profile 410 using the registered product information.

Here, the product profile 410 contains unique information for each product and may include product name, product identification number, manufacturer, manufacturing date, purchase date, purchase price, and buyer unique identification information (UUID). there is.

Next, the NFT generator 220 first creates an NFT for the product based on the product profile 410, and registers the generated NFT in the blockchain 400.

To explain this again with reference to FIG. 2, for example, when a seller (user A) registers a product in the product register 210 for product 1, the NFT generation unit 220 generates the first NFT (NFT) for product 1. 1) is generated. Subsequently, as product 1 is traded through user B and user C, that is, buyers, the NFT generator 220 generates NFT 1' and NFT 1'' in which NFT 1 is updated. At this time, the updated NFT is shared through the blockchain 400.

Likewise, when the seller (user D) registers the product in the product register 210 for product 2, the NFT generator 220 creates the first NFT (NFT 2) for product 2, and then product 2 As the transaction progresses through User E and User F, that is, buyers, the NFT generator 220 generates NFT 2' and NFT 2'' in which NFT 2 is updated. At this time, the updated NFT is shared through the blockchain 400 in the same way as Product 1.

Here, according to the present invention, the blockchain 400 for the same product may be connected to the same blockchain. For example, if product 1 and product 2 correspond to the same product, NFT 1 and NFT 2 may be connected and configured through the same blockchain 400.

In blockchain, a block means data (information), and blockchain is a technology that creates a system that connects this data so that everyone can check it and thus cannot be manipulated. Using blockchain, important transactions are possible without powerful institutions such as governments or banks.

In addition, NFT (Non-fungible token) is a virtual token that proves the owner of a digital asset using blockchain technology. NFT itself is a known technology, so a detailed description of it will be omitted.

In this way, according to the present invention, using NFT using blockchain technology, it is possible to provide information about distributed products transparently and fairly.

In the present invention, the product transaction unit 230 can generate a transaction profile 420 that is created and updated every time a transaction for the same product occurs. The transaction profile 420 may include buyer unique identification information, seller unique identification information, sale date, sale price, and transaction method.

Accordingly, according to the present invention, the product certification unit 240 performs verification of the validity of the transaction and the validity of the product based on the transaction profile 420 and the product profile 410 and provides it to the user. do.

Therefore, according to the present invention, through product verification through the product profile 410 and transaction verification through the transaction profile 420, it is possible to confirm the source of the product, product proof, ownership, and share the transaction amount, thereby ensuring fair trade. It is possible to encourage relationships and has the effect of preventing accidents such as theft and fraud.

According to one implementation of the present invention, the service server 200 may further include a price evaluation unit 250 that calculates the appropriate price of the traded product and provides it to the buyer.

In order to calculate the appropriate price of the product traded here, the service server 200 includes the average price information generated by calculating the average price of products of the same type from the NFT information shared on the blockchain 400. , When NFT is updated, an updated NFT is created by reflecting this.

At this time, the average transaction information may be calculated by reflecting a time weight that is inversely proportional to the time elapsed from the transaction time. For example, if the transaction was made recently, most of the transaction price will be reflected, and if the transaction time has passed considerably, low weight is given to past transactions to calculate the average transaction price.

Based on this, the price evaluation unit 250 calculates appropriate price information from the average price information. At this time, the appropriate price information can be calculated by reflecting the weight of the depreciation factor of the product in the average price.

Here, the depreciation factor may include, for example, the period of use and number of transactions of the product. Therefore, if a long period of time has passed since the product was first manufactured, the average transaction price can be calculated by deducting a large amount of depreciation, and even if the number of transactions is large, the appropriate transaction price can be calculated by deducting a large weight.

Accordingly, according to the present invention, it is possible to induce a reasonable transaction relationship by calculating and providing an appropriate price for the transaction product based on transaction history using blockchain.

Hereinafter, the process of product trading by the product trading system of the present invention will be described with reference to FIG. 3.

According to the present invention, the product transaction unit 230 basically mediates product transactions through an escrow service. Escrow is used during commercial transactions to ensure the safety of transactions by having a trustworthy, neutral third party mediate between sellers and buyers to transact money or goods.

In the present invention, in the product transaction by the product transaction unit 230, first, when the seller applies for product registration to the service server 200 (S110), the service server 200 registers the product for sale (S210) , Create an NFT and register it on the blockchain (S220). Next, when the buyer applies to purchase the product registered for sale (S310), the service server 200, which has received the purchase request (S230), requests payment (S240). Subsequently, the buyer who receives the payment request (S320) pays the cost for the purchased product to the system and transmits the purchase payment information to the service server 200. When the buyer pays for the purchased product to the system, the system processes the NFT and payment through a third-party escrow service (S250).

When payment information is transmitted to the seller as described above, the seller ships the product, transmits the product shipment information to the service server 200 (S120), and the service server 200 transmits the product shipment information to the buyer. (S260). Then, when the buyer receives the product shipment information (S340), the system proceeds with escrow, that is, requests payment (S350), and the system pays the fee to the seller (S271) and transfers NFT ownership to the buyer (S272). transaction is carried out.

Meanwhile, among the products traded in the product trading system of the present invention, there may be stolen products or products traded without going through normal distribution channels. Therefore, Figure 4 is a flow chart of the transaction protocol for this case in the system of the present invention.

Referring to FIG. 4, the service server 200 is configured for sale when a product with the same unique identification information as the existing product profile 410 is registered for sale, and the final owner and the product sales registrant on the NFT of the product do not match. , it is determined whether the unique identification information of the product registered for sale matches the unique identification information of the product for which transaction suspension has been requested (S210'), and if transaction suspension for the product is requested, an arbitration protocol is executed (S230') ).

In the present invention, the arbitration protocol proceeds in the following order. When a request is made to stop trading for the product, the service server 200 first creates a virtual buyer profile (S240') and approves the seller's sales registration (S250').

Subsequently, the service server 200 generates virtual buyer's virtual deposit information for the product registered for sale (S260') and provides the virtual deposit information to the seller (S270'). Subsequently, when the shipment information (S130') of the product by the seller is received by the service server 200 (S280'), the service server 200 receives the seller, the final owner of the NFT of the product, and the transaction suspension requester (500). ) is notified by sending that the arbitration protocol process for the product is in progress (S290').

Accordingly, according to the present invention, through NFT, safe transactions can be induced through product ownership and escrow services, accidents such as theft and fraud can be prevented, and damage to theft victims can be reduced by implementing mediation for stolen items. There is a real relief effect.

Although the preferred embodiments of the present invention have been described above, those skilled in the art can add, change, delete or add components without departing from the spirit of the present invention as set forth in the patent claims. The present invention may be modified and changed in various ways, and this will also be included within the scope of rights of the present invention.

For example, each component described as unitary may be implemented in a distributed manner, and similarly, components described as distributed may also be implemented in a combined form. The scope of the present invention is indicated by the claims described below rather than the detailed description above, and all changes or modified forms derived from the meaning and scope of the claims and their equivalent concepts should be construed as being included in the scope of the present invention. do.
