The cryptocurrency transaction support system according to an embodiment of the present invention may include a first user device 10, a second user device 20, and a server 100. According to various embodiments of the present disclosure, the first user device and the second user device may mean the same device, but a user who registers an object on the platform (server 100) for convenience of understanding the operation performed in the system of the present invention. The device of the user who pays the cryptocurrency on the platform to purchase the ownership of the property is named the second user device 20. For reference, the article that may be requested to be registered by the first user device 10 may include all conventional payment means for purchasing a cryptocurrency. Accordingly, precious metals, gift certificates, bonds, and currencies, including goods such as electronic products, which are commercially available, can be registered as 'goods' for purchasing cryptocurrencies.

According to an embodiment of the present invention, a user of a first user's device 10 (a trade registrant, hereinafter also referred to as a first user for convenience) may use a specific item owned by the user on a platform as a means for purchasing cryptocurrency. You can request to register. In response, the server 100 interworking with the platform on which the property is registered may determine the value, authenticity of the item requested for registration on the first user device 10, and whether the property can be registered based on the information. Thereafter, the server 100 registers the item requested by the first user device 10 on the platform only when it is determined that the item requested by the user is a property that can be registered, and as much as the value of the corresponding item requested by the first user device 10. You can pay cryptocurrency. Accordingly, the user of the first user device 10 may obtain an effect of purchasing the cryptocurrency of the server 100 with the items he owns.

Thereafter, the server 100 may receive a purchase request of another user for the registered item. When a request for purchase of the property is received from the second user device 20, the server 100 receives the cryptocurrency equivalent to the amount of money given to the property from the second user device 20 and correspondingly requests from the second user device 20. You may transfer ownership of your property.

According to various embodiments of the present disclosure, a user of the first user device 10 may register an item that he / she wants to register with, and deliver the item to the server 100, and an end purchaser who wants to purchase the item that he / she wants to register. Yes, only the ownership of the item may be transferred until the second user device 20 side) is determined. The tenant of the first user device, which is the registrant of the sale, delivers the item directly to the second side of the second user device in which ownership of the final goods is assigned. Cost to deliver to the second user side) can be prevented from wasting time and money.

In FIG. 1, the article is actually delivered to the second user device 20 that initially requested the purchase of the article after the article is registered on the platform of the server 100. However, according to various embodiments of the present disclosure, after ownership of an item registered in a server is transferred to a specific user side (eg, a second user), ownership of the article may be sold to another user side (eg, a third user). . As such, the server 100 may enable a cryptocurrency transaction between users through the transfer of ownership of the item even if there is no substantial movement of the item in the form. And finally, the user who wants to actually award the item can request the actual delivery of the item, so that the item registrant can deliver the item to the final recipient (eg, a third user).

According to various embodiments of the present disclosure, the server 100 may separately classify items to which items to be registered are required to set a delivery date. The server 100 may separately classify items for which a physical transaction must be completed within a certain period, such as a performance ticket having a deadline determined or an electronic product affected by depreciation. In this way, the registrant may request the registrant to set a delivery date (for example, a period during which the goods giver should apply for the actual delivery) for the goods that must be completed in the real transaction within a certain period of time. Accordingly, the registrant (first user) who registers the article on the server 100 may set a delivery date of the article to be registered. In addition, the second user who wants to receive the real item may request delivery of the corresponding item within a specified date at the time of registering the item, and in response, may receive the actual item delivered from the registrant.

The server 100 according to an embodiment of the present invention may be configured to include a communication unit 210, a storage unit 220, and a control unit 230. The controller 230 may include a registration examination unit 231, a price payment unit 232, and a term rental execution unit 233.

First, the communication unit 210 may perform communication with a plurality of user devices (eg, first user device 10 and second user device 20). In detail, the communication unit 210 may receive a goods registration request and a cryptocurrency purchase request signal transmitted from the first user device 10. When it is determined that the item requested to be registered from the first user device 10 can be registered, the communication unit 210 may register the item and transmit a cryptocurrency of an amount corresponding to the item to the first user device 10. In addition, the communication unit 210 may communicate with a plurality of user devices that want to purchase a pre-registered item on the server-side platform with cryptocurrency. The communication unit 210 may receive an item purchase request signal from user devices that want to purchase a pre-registered item, and in response, the communication unit 210 may transmit ownership information of the corresponding item to the user device that wants to purchase the item. .

The storage unit 220 may store information on details of registration of goods and transaction details of goods and cryptocurrencies performed according to an embodiment of the present invention. In addition, the storage 220 may store reference information for determining whether the property to be registered in the first user device 10 can be registered. The reference information may mean a classification criterion of a property, a depreciation ratio calculation formula, a criterion for false listing (eg, blacklist information, etc.).

In addition, the storage unit 220 may record information on whether the purpose of registering the property on the user device side is the sale of goods or the rental of a term system (rental of the cryptocurrency for a certain period of time). In addition, the storage unit 220 may additionally store information required when a user borrows a cryptocurrency (eg, an interest setting method generated according to a period, a reference condition for automatically disposing of a secured property, etc.). .

In addition, the storage unit 220 may store information required for various operations according to an embodiment of the present disclosure.

The controller 230 may include a registration examination unit 231, a price payment unit 232, and a term rental execution unit 233.

First, the registration review unit 231 may evaluate whether the property requested to be registered in the first user device 100 can be registered. The criterion for determining whether the property can be registered may be, for example, whether the difference between the amount of the goods presented by the property registrant and the result value of the value of the product is judged. In addition, the controller 230 may suspend or limit the registration of the property when the property requested to be registered is suspected to be a false property, or when it is determined that there is a possibility of abuse.

The price payment unit 232 may register the property, which is determined to be a registerable item, on the platform, and may pay the cryptocurrency to the first user, the cryptocurrency whose amount corresponding to the value of the registered property. In addition, the payment price payment unit 232 may control to separately store the payment status for the sale. According to various embodiments of the present invention, the payment price unit 232 fills in the transaction of the cryptocurrency by filling in the contract details that the paid cryptocurrency is charged again if the delivery of the registered property is not fulfilled within a predetermined time period. You can carry out the transaction.

The term rental execution unit 233 may perform a property registration and a cryptocurrency rental function when the first user sets the property as collateral only for a preset period and wants to rent a corresponding cryptocurrency for the corresponding period. A detailed description of the term rental performing unit 233 will be described with reference to FIG. 5.

Hereinafter, the registration examination unit constituting the control unit 230 will be described with reference to FIGS. 3 and 4.

First, referring to FIG. 3, the registration review unit 231 may include a property value evaluation unit 2311, a false sale determination unit 2312, a transaction information confirmation unit 2313, and a registration possibility evaluation unit 2314.

Description of the property value evaluator 2311 will be described with reference to FIG. 4.

The false sale determination unit 2312 may perform an operation of determining whether the property requested by the first user to register is a false sale. For example, the false sale determination unit 2312 determines whether the first user requesting to register a particular item is a registered blacklist member, and if the member has a history registered on the blacklist, the user's property is a false sale. It can be evaluated as. According to various embodiments of the present disclosure, the false sale determination unit 2312 may assign a false sale score to a property determined to have a high possibility of false sale, and in the case of a user whose history is recorded on a blacklist, the false sale score is increased. It may be given as much as a predetermined value. In addition, scores for false items can be given according to various evaluation methods (e.g., whether they are the same as pictures already registered or whether they expired or not), and false scores can be given more than a preset value. The registered property may be determined to be a property that cannot be registered in the registration possibility evaluation unit 2314.

The transaction information verification unit 2313 may perform an operation of confirming information related to a transaction. In this case, the transaction information may include, for example, price information and transaction quantity information of the property input by the first user. In addition, according to various embodiments, the transaction information confirmation unit 2313 may check photos and other descriptive information about the property provided by the first user when the property is requested to register. You can check it. The date information may mean a deadline, and the buyer of the item may resell to another user within the deadline. A buyer of an item may request to award the item within the deadline registered by the first user, even if he or she wishes to award the item without reselling the item.

According to various embodiments of the present disclosure, the transaction information confirming unit 2313 may check whether the goods delivery deadline recorded by the user has elapsed, in addition to checking the goods delivery date information recorded by the first user. As such, the transaction information confirming unit 2313 may re-permit registration review even before the initial transaction is performed on the previously determined items. If the result of re-evaluation of registration registration is found as a result of determining that registration needs to be restricted, the registration possibility evaluator 2314 may suspend the sale of the property. For example, when a performance ticket having a performance date is registered, the transaction information confirming unit 2313 may determine the property as invalid for sale after the performance date of the ticket has elapsed. Thereafter, the registration possibility evaluator 2314 may suspend the transaction of the article (performance ticket) based on the information confirmed by the transaction information confirmer 2313.

The registration possibility evaluator 2314 may determine whether the corresponding item may be registered based on the information about the item evaluated in the registration review unit 231. In this case, the information used as the criterion may be stored in the storage 220.

The registration possibility evaluator 2314 compares the price information of the property submitted by the first user when the property is registered with the value of the property evaluated by the property value evaluator 2311, and if it is determined that the two values differ from each other by a predetermined value or more, 1 You can ask the user for coordination. Accordingly, if the difference between the item price submitted by the first user and the value evaluated by the property value evaluator 2311 is less than or equal to a preset value, the registration possibility evaluator 2314 may reevaluate the property as a registerable item.

As such, the registration likelihood evaluator 2314 calculates the difference between the values of the two items on the basis of the price information evaluated by the property value evaluator 2311 and the price information submitted by the first user who registered the property. Can be evaluated. In addition, the registration possibility evaluator 2314 may evaluate whether or not the registration possibility is based on the scores of false listings (eg, a score given when suspected of a false listing) of the specific listing evaluated by the false listing determining unit 2312. The false sale score may be given, for example, when the account of the first user has a history of false sale, when the account of the first user has a history of non-delivery. In addition, as the number of times of false sale transaction history and undelivered history of the first user increases, the value of the false sale score granted to the first user may increase.

The property value evaluator 2311 will be described with reference to FIG. 4.

Referring to FIG. 4, the property value evaluator 2311 may include a sector classification unit 2311a, a depreciation evaluation unit 2311b, a planner matching unit 2311c, a planner compensation unit 2311d, and an expected price calculator 2311e.

First, the category classification unit 2311a may perform an operation of classifying the property by category based on the information of the property requested for registration. According to various embodiments of the present disclosure, the classification of the property may be set for each category having a similar degree of application of the depreciation ratio. Specifically, the classification unit 2311a according to the field is classified into categories having similar degree of application of depreciation costs, group 1 having a large influence of depreciation costs (eg, electronic products, etc.), group 2 having no effect of depreciation costs (eg, gift certificates, Precious metals), and products can be classified into three groups (eg, antiques, limited edition products, etc.) that increase in value over time. Alternatively, the category classification unit 2311a may designate a category of the product by a professional field of an expert who will determine the value of the product. For example, the category classification unit 2311a may classify items by classifying items into a culture art-related category, an electronic product category, and a fashion category.

The depreciation evaluation unit 2311b may evaluate a degree of depreciation corresponding to the passage of time of the item requested to be registered. This may be calculated according to a depreciation formula for each kind of pre-stored items (eg, TV, refrigerator, notebook, etc.) or for each category of items (eg, electronic products, precious metals, etc.). The depreciation formula may be stored in the storage unit. Alternatively, the depreciation evaluation unit 2311b may calculate a depreciation formula for each category of the item by referring to the hourly transaction price trend collected from the web server, and apply it when calculating the depreciation of the corresponding item.

The planner matching unit 2311c may match a planner who determines the value of the item requested to be registered. The planner may include artificial intelligence and may be set up with multiple user accounts. The planner can set in advance the kind or field of the article to be evaluated. Accordingly, the planner matching unit 2311c may support a plurality of planners corresponding to the type or category of the item requested to be registered and priced from the planners. Accordingly, there is an effect that the article can be evaluated by an expert with expertise in the article. For example, in the case of art, when a value is assigned by a person who does not have expertise in the field, a problem may arise in that the value is overvalued or undervalued. As the expert knowledge may be required to determine the value of the article as described above, the planner matching unit 2311c may match the expert of each item or category requested to be registered as a planner.

According to various embodiments of the present disclosure, when a product identical with an item for which a value is to be set is traded on the web, the maker matching unit 2311c may include a portal through which the item is traded as the planner and match it.

The planner compensation unit 2311d may perform an operation of providing a reward to the planner who evaluated the value of the item requested to be registered. In this case, the reward may be given as a reliability score for each account holder. Alternatively, the reward may be given in a small amount of cryptocurrency in accordance with the closing of the transaction.

According to various embodiments of the present disclosure, when assigning the reliability score to a scheduler account, the planner rewarder 2311d may operate based on a difference between the value of the goods set by the individual planner and the average value set by the entire planner. . For example, if the total number of people in the entire planner is greater than or equal to the preset number and the average price by the overall planner is calculated, the planner compensation unit 2311d gives a reliability score to the planner account showing the error rate greater than or equal to the preset percentage from the average price. Credit scores can be assigned to those account holders who do not, or subtract, and show a match rate above this set percentage. The confidence scores later assigned to the planner may serve as weights in pricing.

In one embodiment, the number of subjects, namely, value creators, set by sector may be limited, and the qualification of a value maker may be granted to only a limited number of accounts based on the confidence score. In one embodiment, the qualifications of the value maker may change in real time based on the confidence score. In another embodiment, the qualification of the value creator can be renewed at predetermined intervals and is elected based on the votes of the blockchain participants, such as Block Producer (BP) with the moderator of the blockchain network (mainnet). It is also possible. According to an embodiment, a separate vote may be performed or a vote may be substituted for a reliability score.

The estimated price calculation unit 2311e calculates an average price by adding the estimated price information submitted by the corresponding planners when the scheduler for the item requested to be registered through the scheduler matching unit 2311c is matched, and calculates the estimated price of the corresponding article. can do. When the estimated price calculator 2311e is determined to be a product affected by the depreciation cost based on the type or category information of the item, the estimated price calculator 2311e adds the depreciation cost calculation formula to the estimated price calculated by the planners to calculate the second estimated price. can do.

Hereinafter, the term rental performing unit 233 in the controller 230 of FIG. 2 will be described in more detail.

The term rental execution unit 233 may be configured to include a period-based interest planning unit 2331, the sale value change determination unit 2332, automatic sale processing unit 2333.

If the first user applies for a fixed term loan, the interest policy unit 2331 for each period may calculate the amount that can be rented according to the value of the corresponding goods. Thereafter, if the first user presents the amount to be rented within the amount that can be borrowed, the interest policy 2331 for each period is based on the security set period (cryptocurrency lending period) of the goods and the interest based on the loan amount requested by the first user. Can be formulated. At this time, if the rate of decrease in value of the mortgage-set items determined by the property value fluctuation determination unit 2332 is greater than or equal to a predetermined threshold value, the interest policy 2331 for each period may be controlled to increase the amount of interest over the period. have.

The sale value change determination unit 2332 may determine whether the sale value is changed, and may determine whether the value is changed due to depreciation. In addition, the sale value change determination unit 2332 may collect current price information (eg, gold price) and determine the value change of each item based on the current price information.

If the first user fails to re-enter the cryptocurrency after the period set by the lending cryptocurrency elapses, the automatic sale processor 2333 may sell the property to another user. At this time, when determining the point of time for the sale process in the automatic sale processor 2333, it can refer to the price information of the corresponding item determined by the value change determination unit 2332. For example, if the first user borrows cryptocurrency with collateral for gold, but overdues interest and principal for a certain period of time, the automatic sale processor 2333 may determine to sell the property. However, at this time, even if the sale itself is determined, the decision on the selling time may be set based on the price information determined by the selling value change determination unit 2332. For example, when the gold price determined by the selling value change determination unit 2332 reaches a predetermined amount, the automatic selling processing unit 2333 may register the platform as a for sale item to sell the secured item.

The controller 230 of the present invention may perform operation 605 of receiving a property registration request from the first user. Thereafter, the controller 230 may perform operation 610 for performing an audit on the property requested for registration. In this case, the controller 230 may determine an expected value of the corresponding item, based on the information of the requested item. The controller 230 may determine whether the trade item is a tradeable item. The property registration examination operation will be described in more detail with reference to FIG. 7.

After that, the controller 230 performs operation 615 to determine whether the property is a registerable item. If it is determined that the property is a registerable item, the controller 230 registers the item as a transaction item on the platform and corresponds to the price of the corresponding item. In operation 620, the payment to the first user may be performed. In this case, the price of the corresponding sale item may be estimated price information calculated by planners composed of related experts, including price information actually traded.

If it is determined that the property requested by the first user to be registered is a property that cannot be registered (for example, an illegal property, a property suspected of being a false property, etc.), the controller 230 may perform operation 625 of restricting registration of the property. Can be.

The controller 230 may perform operation 705 for checking the property information and the user request price information included in the property registration request. Thereafter, the control unit 230 may perform operation 710 for determining whether the property is a false property based on the property information (eg, whether the first user has registered a blacklist, whether the requested picture has a registered history, etc.). . In operation 710, it may further be determined whether the property is illegal. For a sale that is determined to be a false sale or illegality, registration may be immediately restricted without performing a pricing operation and subsequent operations.

Thereafter, the controller 230 may perform operation 715 for classifying the property by field. The classification operation is to more clearly evaluate the value of the property, and in particular, may be a task for requesting a price-specific price setter for each sector.

Thereafter, the controller 230 may perform operation 720 for matching the price setters for each sector according to the type or category of the property requested to be registered and calculating an expected price. Thereafter, the store control unit 230 may perform operation 725 to determine whether the field of sale is a field for applying depreciation. Operation 725 may be an operation for determining whether the category of the item is a category whose value drop due to depreciation is greater than or equal to a preset reference value. Accordingly, when it is determined that the property requested for registration is a property in a field to which the depreciation cost does not apply over a period of time, the controller 230 may control to proceed to operation 735. On the other hand, if it is determined that the item requested to be registered is an item in the field of application of depreciation (or an item whose value falls due to the depreciation cost is greater than or equal to a predetermined value), the controller 230 adds the depreciation cost information according to the period and the estimated price (second To calculate the expected price of the car).

After the operation, the controller 230 may perform operation 735 to determine whether the difference between the calculated expected price and the user request price is greater than or equal to a preset value. At this time, if the difference between the sale price of the corresponding item requested by the user and the expected price of the corresponding item calculated by the controller 230 is greater than or equal to a preset value (eg, a preset ratio), the controller 230 requests an adjustment from the first user. Operation 740 may be performed. On the other hand, if the difference between the expected price of the property calculated by the controller 230 and the user request price is not more than a preset value, the controller 230 may perform operation 750 to determine that the property is immediately registerable.

After the controller 230 requests an adjustment from the first user, the controller 230 may perform operation 745 to determine whether the request price adjustment of the first user has been performed according to the request. If the price adjustment is performed and the difference between the user's request price and the expected price calculated by the controller 230 is less than or equal to a preset value (or ratio), operation 750 determines that the property is a registerable property. Can be performed. However, when the first user does not perform the tuning, the controller 230 may perform operation 755 in which it is determined that the property is not registerable.

In addition, although not shown in the drawings, other operations according to various embodiments of the present disclosure may be implemented. For example, the controller 230 according to an exemplary embodiment of the present invention may permit a part of a consumer (second user) to be acquired for one item of a specific category. For example, the partial acquisition may be carried out in a concept such as a kind of down payment. Accordingly, even if the second user does not pay the entire amount for a particular item, the second user may express a willingness to purchase the item for only a partial amount. When the partial acquisition operation is performed, the controller 230 may request the second user to perform a cryptocurrency payment operation for the entire acquisition after a predetermined period of time after the partial acquisition operation is performed.

In addition, according to various embodiments of the present disclosure, the controller 230 may receive a price and product information that the second user wants to purchase and match the pre-registered product based on the input. When the second user inputs the amount of cryptocurrency to be paid along with the type of the item that the second user wants to acquire, the controller 230 checks the pre-registered item information matching the information input by the second user, and registers the first user. Can be matched to the second user.

In addition, when matching the first user and the second user, the controller 230 may transmit a message window for inquiring whether the first user and the second user exist or whether the first user and the second user are to be matched. . Accordingly, each user can be provided with information about the other party according to the other party's approval (approval of the direct transaction with the matched user), thereby establishing mutual trust. As described above, according to the exemplary embodiment of the present invention, the first user and the second user can immediately perform a direct transaction by directly matching the direct transaction targets corresponding to the information desired by the controller 230. Although the present invention has been described in detail with reference to the above examples, those skilled in the art can make modifications, changes, and variations to the examples without departing from the scope of the invention. In short, in order to achieve the intended effect of the present invention, it is not necessary to separately include all the functional blocks shown in the drawings or to follow all the orders shown in the drawings in the order shown; Note that it may fall within the scope.
