The block chain-based tagging system 100 according to an embodiment of the present invention utilizes a block chain network, and through a tagging function, it is possible to overcome the restrictions on purchase qualifications according to the characteristics of goods, so that commerce is more free and It is characterized in that it is possible to promote the globalization of the economy by making this happen frequently.

The blockchain-based tagging system 100 according to the present embodiment may include a tagging server 110 and user terminals 120 and 130 . Also, the tagging system 100 may be linked with an external e-commerce system 50 .

The user terminals 120 and 130 are terminal devices operated by a user using a blockchain-based tagging service. As a computing device equipped with an operating system that can be installed through a download or can be installed through a download or a blockchain-based tagging service-related application or program (hereinafter collectively referred to as an application) according to the present embodiment, for example, a smart It may be a phone, a tablet PC, a notebook computer, a desktop PC, and the like.

The tagging server 110 is a server device that communicates with the user terminals 120 and 130 and provides a blockchain-based tagging service through a blockchain network.

In the tagging service according to the present embodiment, a user is divided into a tagger and a taggee.

The tagger refers to a user who can purchase a specific product through the e-commerce system 50 . That is, it corresponds to a user with limited purchasing qualifications. For example, if a specific product is a US lottery ticket, a tagger may be a user who resides in US territory and can purchase US lottery tickets. Alternatively, when a specific product is an overseas real estate, a user who has a nationality that can purchase the corresponding real estate locally may be a tagger.

In this embodiment, goods may include intangible goods such as stocks and contents as well as tangible goods.

A user who is unable to purchase a particular good through the e-commerce system 50 may become a tagger instead of a tagger. That is, a user who cannot purchase a desired specific product because he or she does not have limited purchasing qualifications corresponds to a prenatal period.

Tagger can register a smart contract including a business model such as a purchase plan for a specific good and a distribution plan for the generated profits in the blockchain network through the tagging server 110 .

Taegi can check the smart contract for a specific good registered in the blockchain network, and perform the tagging operation of registering as a purchase supporter (i.e., contracting party) for a specific good for a smart contract that presents a desired business model. have. Through the tagging operation, Taegi will be able to support part or all of the purchase amount in virtual currency for specific goods corresponding to the smart contract proposed by Tagger.

The process of linking users who have limited purchase qualifications and users who do not have such a limited purchase qualification corresponds to the tagging function.

According to an embodiment, even a user with limited purchase qualifications may participate in Taegi supporting a part of the purchase amount for another user (ie, tagger). In other words, having a limited purchase qualification may not be an essential condition for gestation.

The user terminals 120 and 130 included in the tagging system 100 include a first user terminal 120 (tagger terminal) functioning as a tagger, and a second user terminal 130 functioning as a taggee. (fetal terminal) can be divided.

A user who uses the tagging system 100 may act as a tagger or a fetus according to the characteristics of the goods as described above.

Referring to FIG. 2 , the configuration of the tagging server 110 is illustrated.

The tagging server 110 may include a block chain linkage unit 111 , a bank management unit 112 , a system linkage unit 113 , a user authentication unit 114 , an SC management unit 115 , and a tagging management unit 116 . .

The blockchain linking unit 111 links the tagging server 110 to the blockchain network.

A blockchain is a list of records that encrypts a block containing transaction details through a hash function and connects them in a chain format. Due to the link-based distributed data characteristics of the block chain, it is fundamentally impossible to modify the transaction details that have already occurred.

As the size of transactions in the online market grows, the importance of building an e-commerce system with enhanced security is increasing. can be blocked

A smart contract (SC) is an automated contract system that automatically executes contracts when all programmed conditions are met. In the past, a number of documents were required for a contract to be concluded and executed, but the smart contract designates the contract conditions in computer code and executes the contract if the conditions are met.

In this embodiment, the block chain linker 111 may be linked to Ethereum, a block chain platform specialized for smart contracts among block chain networks.

The blockchain linkage unit 111 may be configured to enable creation and registration of smart contracts according to the Ethereum platform. Therefore, the tagging server 110 enables the tagging terminal 120 to register a smart contract for a specific good, and the tagging terminal 130 checks multiple smart contracts and tagging the smart contract for which the contract is desired. can be implemented to make it possible.

In addition, the block chain linkage unit 111 may build a virtual currency transaction system according to a smart contract. Here, the virtual currency may be one of Bitcoin, Ethereum, etc. that are circulating in the market. Alternatively, it may be a Tagging Me Coin (TMC), which is a separate virtual currency mined or traded by the tagging system 100 according to the present embodiment.

The bank management unit 112 serves as an exchange between real money and virtual currency so that transactions using virtual currency are made. If you wish to purchase a virtual currency for using the tagging service in the tagging terminal 120 and/or the tagging terminal 130, when real money is deposited, a virtual currency corresponding to the amount can be paid to the virtual currency wallet.

And virtual currency transaction between the tagger terminal 120 and the baby terminal 130 for the conclusion of the smart contract, virtual currency transaction between the tagger terminal 120 and the baby terminal 130 corresponding to the implementation of the smart contract, and electronic commerce It is possible to manage real currency transactions or virtual currency transactions with the e-commerce system 50 that is used.

The system linkage unit 113 interworks with the external e-commerce system 50 , and makes it possible to inquire and confirm transaction information regarding goods corresponding to the smart contract registered by the tagger terminal 120 . The goods transaction information may include goods type, whether goods transaction is true, purchase or sale amount information, and the like.

The user authentication unit 114 authenticates the user who operates the user terminals 120 and 130 . In this embodiment, for example, KYC authentication, which is one of the user's identity authentication, may be made for virtual currency transactions.

The user authentication unit 114 may function as the tagger terminal 120 or the fetal terminal 130 only for the user terminals 120 and 130 for which KYC authentication has been performed.

The SC management unit 115 manages the smart contract registered in the blockchain network. The registered smart contract can be searched by a general search algorithm, and the search result can be expressed in various ways that the user can check. For example, a registered smart contract may be classified according to a staggered basis or a staggered basis. Alternatively, it may be classified according to various criteria such as keywords or tagging amounts included in the smart contract.

In addition, the SC management unit 115 may manage matters related to the smart contract between the tagger terminal 120 and the fetal terminal 130 .

The SC management unit 115 may review whether the tagger terminal 120 meets a pre-specified registration condition for the smart contract requesting registration, and may allow registration if the registration condition is satisfied. Conditions for registration may include whether or not it is a reasonable transaction in common sense.

In addition, it is possible to analyze the goods transaction information regarding the smart contract provided by the e-commerce system 50 and check whether the smart contract in which the tagger and the tag are matched through the tagging operation is executed.

In addition, according to the implementation of the smart contract, the bank management unit 112 can be controlled so that the virtual currency transaction can be made according to the distribution standard according to the business model.

The tagging management unit 116 may manage the tagging state for the smart contract managed by the SC management unit 115 .

Although any smart contract is registered by the tagger terminal 120, tagging by the tagger terminal 130 is not performed for all smart contracts. Accordingly, the tagging status including the tagging information corresponding to the registered smart contract and the tagging information in the corresponding smart contract may be managed by the tagging management unit 116 .

In addition, the tagging management unit 116 may match the tag with the registered smart contract. When there is a predetermined tagging request for a desired smart contract in the fetal terminal 130, the fetal terminal 130 may be tagged to the smart contract, and matched with the tagger terminal 120 in which the corresponding smart contract is registered.

When tagging by the tagging terminal 130 occurs, the tagging management unit 116 may receive an operating fee for the blockchain-based tagging system 100 in a predetermined amount according to the tagging. It is basic to accept and receive the operation fee in the aforementioned virtual currency, but depending on the situation, it may be exchanged in real money.

In addition, the tagging management unit 116 may also set a pre-specified fee for the registration request of the smart contract through the tagger terminal 120 .

3 shows the configuration of the first user terminal (tagger terminal 120).

The tagger terminal 120 may include an SC registration unit 121 , a commerce execution unit 122 , and a first virtual currency wallet 123 .

The SC registration unit 121 creates a smart contract related to the transaction of the goods that the tagger terminal 120 wants to transact through the e-commerce system 50 and registers it in the blockchain network through the tagging server 110. A registration request is transmitted to the tagging server 110 .

The smart contract requested to be registered from the SC register 121 to the tagging server 110 includes key conditions (contract conclusion conditions, fulfillment conditions), business model information related to goods (type of goods, revenue distribution or joint ownership, personal purchase and ownership, etc.) ) may be programmed.

Conditions for signing the contract may include conditions (tagging conditions) regarding the fetuses desired for recruitment, for example, the quantity of fetuses (or tagging), and a tagging amount for one tagging.

Performance conditions may include whether goods are purchased. For example, in the case of lottery tickets, the act of purchasing a lottery ticket may be a condition of fulfillment.

The business model information includes how to distribute specific goods between the matched tagger and fetus through tagging operation through the corresponding smart contract. For example, in the case of a lottery, the distribution ratio of the winning amount when the lottery is won may be included in the business model information. In the case of real estate, the business model information may include whether or not ownership is jointly owned when ownership is transferred according to the purchase of real estate, whether ownership transfer is registered according to joint ownership, and the like.

When the smart contract is validated by tagging the smart contract registered by the SC registration unit 121 by the baby terminal 130, the commerce execution unit 122 is configured to use the external e-commerce system 50 according to the smart contract. ) through which goods transactions related to smart contracts are executed. For example, in the case of a lottery ticket, it may be a purchase of a lottery ticket, and in the case of real estate, it may be a purchase of real estate.

The commerce executed by the commerce execution unit 122 may be an electronic commerce performed online with the electronic commerce system 50 . In the case of offline commerce, it is not easy to check whether the commerce is executed. In this embodiment, the online electronic commerce is targeted.

The first virtual currency wallet 123 stores virtual currency necessary for smart contract registration and transaction execution.

Basically, a virtual currency of a value corresponding to the real money deposited by the tagger may be paid to the first virtual currency wallet 123 .

In addition, a predetermined virtual currency may be paid to the tagging server 110 as a deposit for guaranteeing implementation at the time of registration of the smart contract.

In addition, when tagging is made on the smart contract, a virtual currency corresponding to the tagging amount according to the tagging may be deposited into the first virtual currency wallet 123 .

In addition, when executing a goods transaction with the e-commerce system 50 according to the smart contract, a virtual currency summing up the tagging amount may be paid to the e-commerce system 50 as a transaction amount for the goods.

4 shows the configuration of the second user terminal (the fetal terminal 130).

The tagging terminal 130 may include an SC confirmation unit 131 , a tagging unit 132 , and a second virtual currency wallet 133 .

The SC confirmation unit 131 registers a smart contract related to a product that cannot be purchased because the purchase qualification is limited, or a product that is difficult to purchase alone due to a large or high rarity, is registered in the blockchain network linked to the tagging system 100 . check that it is

If there is a smart contract that Taegi wants to participate in among the smart contracts confirmed by the SC check unit 131, the tagging unit 132 executes a tagging operation for the selected smart contract.

The tagging operation is to send a contract conclusion request indicating that the baby terminal 130 wishes to participate for the contract conclusion for the selected smart contract.

If the smart contract is to recruit one fetus, the contract can be concluded immediately upon request for contract conclusion. If the recruitment is not completed, the smart contract may be destroyed.

The second virtual currency wallet 133 stores virtual currency required for tagging.

In order for the tagging by the tagging unit 132 to be completed, a virtual currency of a specified amount may have to be paid as a down payment to complete tagging for the corresponding smart contract. In this case, the virtual currency stored in the second virtual currency wallet 133 may be The amount of money may be withdrawn.

The tagging amount required for tagging may include an operating fee paid to the operator of the tagging server 110 that provides the blockchain-based tagging service according to the present embodiment.

Hereinafter, a method of providing a blockchain-based tagging service performed in the blockchain-based tagging system 100 according to the present embodiment will be described with reference to FIG. 5 .

First, under the blockchain-based tagging system 100, the first user terminal 120 and the second user terminal 130 may perform user registration for the tagging server 110, respectively (steps S200 and S205). For user registration, user identity authentication such as KYC authentication is required.

The blockchain-based tagging service according to the present embodiment may be provided only for user-registered user terminals. Hereinafter, it is assumed that the first user terminal 120 functions as a tagger terminal and the second user terminal 130 functions as a fetal terminal.

Here, the tagging server 110 is linked with the external e-commerce system 50 to obtain or confirm information about the e-commerce transaction performed through the e-commerce system 50 .

The tagger terminal 120 generates a transaction smart contract (transaction SC) for the goods to be transacted with the e-commerce system 50 and requests registration to the tagging server 110 (step S210). The transaction smart contract may be registered through the tagging server 110 , in particular through the blockchain network linked through the blockchain linkage unit 111 .

The tagging server 110 reviews the transaction smart contract requested for registration, and if there is no abnormality, it registers it through the blockchain network (step S215).

The tagging terminal 130 checks several transaction smart contracts registered in the tagging server 110, and performs tagging expressing the intention to participate in the transaction smart contract that presents a desired business model (step S220).

During tagging, a virtual currency corresponding to the tagging amount (down payment) presented in the corresponding transaction smart contract may be withdrawn from the second virtual currency wallet 133 of the Taegi terminal 130 .

If there is a predetermined amount of tagging for the transaction smart contract, it is considered that the contract conclusion conditions for the transaction smart contract are satisfied, and a contract can be concluded against the transaction smart contract (step S225).

In this case, the tagger that registered the smart contract for the transaction and the tagger who tagged the smart contract for the transaction may be linked. In addition, the tagging amount withdrawn at the time of tagging by the baby terminal may be transferred to the baby terminal 130 for the completion of an e-commerce transaction to be described later. Here, a portion of the tagging amount may be paid to the tagging server 110 as an operation fee.

Thereafter, the tagger terminal 120 may request an e-commerce transaction to the e-commerce system 50 linked to the block-chain-based tagging system 100 in accordance with the business model suggested in the transaction smart contract (step S230). When the e-commerce is requested, the amount for the e-commerce may be paid by adding up the tagging amounts collected by tagging.

In this case, the amount for e-commerce may be paid in virtual currency. This is to prevent the case of submergence without performing e-commerce according to the transaction smart contract when real money is paid to the tagger.

The e-commerce system 50 may check whether the e-commerce conditions specified for the e-commerce request requested by the tagger terminal 120 are satisfied, and if the conditions are met, the e-commerce may be allowed (step S235).

The tagging server 110 includes a system linking unit 113 linking with the e-commerce system 50 to receive the e-commerce results made in the e-commerce system 50 (step S240). The received e-commerce result is managed by the SC management unit 115, and the e-commerce result may be delivered to the tagging terminal 130 tagged in the corresponding transaction smart contract.

In addition, the tagging server 110 may review whether the e-commerce result has been made according to the conditions programmed in the transaction smart contract previously concluded. If the e-commerce result does not match the transaction smart contract, the fact is notified to the e-commerce system 50, and the e-commerce can be canceled or invalidated.

Depending on the characteristics of the goods subject to e-commerce, an update of the status change may be required. For example, when the good is a lottery ticket, a lottery lottery drawing date arrives and a status change as to whether the lottery is won according to the drawing occurs. If the product is real estate, after the contract for real estate transaction is concluded and the down payment is paid, the status change occurs as to whether the name of the real estate item and the balance payment have been made, and whether the ownership of the real estate has been registered.

When there is such a state change, the e-commerce system 50 performs an update according to the state change and delivers the update fact to the tagging server 110 (step S245).

The tagging server 110 may review whether the fulfillment condition of the transaction smart contract is satisfied from the current transaction state provided by the e-commerce system 50 (step S250).

When the fulfillment conditions of the transaction smart contract are satisfied, the contract may be executed according to the business model programmed in the transaction smart contract (step S255).

If the business model was distribution of the proceeds according to the transaction, the proceeds were distributed according to the distribution ratio contracted through the transaction smart contract for the tagger and the taegi to the first virtual currency wallet 123 and the second virtual currency wallet 133, respectively. It can be paid (steps S260, S265).

In addition, before step S220 in this embodiment, the tagging terminal 120 may recruit the tagging terminal 130 for the transaction smart contract registered in the blockchain network by the tagging server 110 .

Members of social network service (SNS) platforms such as Facebook can become one or more of Tagger and Taegi, and after Tagger, a member of a specific SNS platform, registers a transaction smart contract, he and other members of the SNS platform are connected to the social network. You can notify people (e.g., friends on Facebook) that you have registered a transaction smart contract, and recruit interested friends to Taegi.

That is, the blockchain-based tagging service according to this embodiment can provide a new function of tagging among members of the SNS platform in connection with the SNS platform.

According to the present embodiment, even when the supplied goods have a regional limit, a transaction can be made beyond the regional limit.

In addition, when the supplied goods are very expensive or scarce, so it is difficult to own them alone, it is possible to create a new concept of profit by recruiting like-minded people to jointly own them, or by closing a transaction for the goods and distributing the proceeds. We can provide a business model that makes

In this embodiment, when the specific good is a lottery ticket, the contract conclusion condition may be a share of a portion of the purchase price of the lottery ticket. The fulfillment condition may be the fact of winning the lottery, and the business model may be to distribute the winnings of the lottery according to a predetermined condition.

Alternatively, if the specific good is real estate, the condition for signing the contract may be a share of a portion of the purchase price of the real estate. Performance conditions may be the purchase of real estate (complete payment of down payment and balance) and completion of registration of transfer of ownership. And the business model may be joint ownership of the property by Tagger and Tagger. Or it could be that the tagger is in the possession of the tagger and leases it for a certain period of time.

6 and 7 are exemplary implementation diagrams of a tagging service application provided by a blockchain-based tagging system according to an embodiment of the present invention. In each of FIGS. 6 and 7 , a tagger terminal screen and a fetal terminal screen are shown when the goods are lottery tickets.

Referring to FIG. 6 , a smart contract can be created and registered by the blockchain-based tagging service application running on the tagger terminal (see the SMC icon). In this case, for the registration of the smart contract, it is necessary to program the main conditions and business model.

In the case of HELLO Matt! illustrated in FIG. 6, smart contracts related to lottery such as POWERBALL, MEGA MILLIONS, LOTTO AMERICA, LUCKY FOR LIFE, etc. is registered.

The case of creating a new smart contract corresponds to OPEN SLOT, and you can select the type of lottery ticket and select the desired tagging quantity and/or tagging amount.

Referring to FIG. 7 , smart contracts registered in the tagging system can be checked by the blockchain-based tagging service application executed in the Taegi terminal, and a desired smart contract can be selected and tagged by Taegi (HELLO CJ~).

When displaying smart contracts, while displaying information about the tagger, the past history (in the drawing, the winning history) may also be displayed to help in the selection of the taegary.
