1 is a block diagram showing a schematic configuration of a cryptographic currency transaction support system according to an embodiment of the present invention.

The cryptographic transaction support system according to the 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, the first user device and the second user device may refer to the same device. However, in order to facilitate understanding of the operations performed in the system of the present invention, a user who registers the goods on the platform (server 100) Will name the first user device 10 as the first user device 10 and the user device on the platform that pays the cryptographic currency on the platform for purchasing ownership for the sale as the second user device 20. [ For reference, the article that can be requested to be registered by the first user device 10 may include all conventional payment means for purchasing the cryptographic currency. Accordingly, all of the precious metals, gift certificates, bonds, and currencies, including electronic commodities traded on the market, can be registered as 'articles' for purchasing passwords.

According to the embodiment of the present invention, the user of the first user device 10 (a seller register, hereinafter also referred to as a first user for convenience) is allowed to place a specific item owned by the user on the platform You may be asked to register. In response to this, the server 100, which is interlocked with the platform on which the sale is registered, can determine whether the value of the registration-requested article on the first user device 10 side, authenticity and registration of the corresponding sale based on the value. Then, the server 100 registers the requested article on the platform in the first user device 10 only when the sale of the article requested by the user is determined to be a registerable article, You can pay the password. As a result, the user of the first user device 10 obtains the effect of purchasing the encrypted currency of the server 100 side with the article held by the user.

Then, the server 100 can receive a purchase request of another user for the registered article. When the purchase request for the sale is received from the second user equipment 20, the server 100 receives the encrypted money equivalent to the amount of money given to the sale from the second user equipment 20 side, The owner may transfer ownership of the property.

According to various embodiments of the present invention, the user of the first user device 10 may register the article to be registered and deliver the article to the server 100 side, (E.g., on the side of the second user device 20) is determined. The first user device 10, which is the seller of the goods, distributes the goods directly to the second user device 20, to which the ownership of the final goods is designated, so that unnecessary shipping in the middle process (the cost of delivering the goods from the first user side to the server side, To the second user side) can be prevented from being wasted.

 In FIG. 1, after the article is registered in the platform of the server 100, the article is actually delivered to the second user apparatus 20 requesting the first purchase for the sale. However, according to various embodiments of the present invention, ownership of the article registered in the server may be transferred to another user (e.g., a third user) after the ownership of the article is transferred to a specific user (e.g., a second user) . As described above, the server 100 can enable a password currency transaction between users through transferring ownership of the article even if there is no substantial movement of the article having the form. And finally, a user who wants to actually award the item can request the actual delivery of the item, and the registrant can then ship the item to the final recipient (e.g., a third user).

According to various embodiments, the server 100 may separately classify the items to be registered separately from the items for which the delivery date setting is required. The server 100 can classify articles that require the actual transaction to be completed within a predetermined period, for example, a performance ticket whose deadline has been determined, an electronic product affected by a depreciation cost, and the like. In this way, it is possible to request the registrant to set the delivery date (for example, the period during which the article recipient must apply for the physical delivery) for the article for which the physical transaction is to be completed within a predetermined period. Accordingly, the registrant (the first user) who registers the article in the server 100 can set the delivery date of the article he / she wants to register. The second user who wishes to deliver the goods can request the delivery of the goods within the designated time at the time of registering the goods and receive the actual goods delivered from the registrant in response.

2 is a block diagram showing the configuration of the server 100 according to the embodiment of the present invention.

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

First, the communication unit 210 can perform communication with a plurality of user equipments (e.g., the first user equipments 10 and the second user equipments 20). Specifically, the communication unit 210 may receive an item registration request and a password purchase request signal transmitted from the first user equipment 10. [ The communication unit 210 may register the corresponding article according to the determination that the article requested to be registered from the first user apparatus 10 can be registered, and may transmit the encrypted currency of the amount corresponding to the article to the first user apparatus 10 side. In addition, the communication unit 210 may perform communication with a plurality of user equipments for purchasing an article pre-registered in a server-side platform with a cipher. The communication unit 210 receives an article purchase request signal from the user apparatuses to purchase the pre-registered article, and in response, the communication unit 210 can transmit the ownership information about the article to the user apparatus side that desires to purchase the article .

 The storage unit 220 may store information on the registration details of the goods and the transaction details of the goods and the passwords, which are performed according to the embodiment of the present invention. In addition, the storage unit 220 may store reference information for determining whether a sale desired to be registered by the first user device 10 is registerable. The reference information may refer to a classification standard for merchandise, a depreciation cost calculation formula, a false selling criterion (e.g., black list information).

In addition, the storage unit 220 may record information on whether the purpose of registration of the sale of the merchandise on the user equipment side is sales of a product or rental of a fixed-term rental (loan of a product for security for a certain period of time). Further, the storage unit 220 may further store information required when the user borrows the coded money (for example, the interest pricing scheme generated according to the period, the reference condition for automatically disposing the secured property, etc.) .

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

The control unit 230 may include a registration examination unit 231, a sale price payment unit 232, and a term rental service performing unit 233.

First, the registration examination unit 231 can evaluate whether or not the sale requested in the first user equipment 100 is registerable. The criterion for judging whether or not the property can be registered may be whether or not the difference between the value of the goods presented by the property registrant and the result of examining the value of the property is equal to or higher than a predetermined level. In addition, the control unit 230 may suspend or restrict the registration of the sale of the property when it is determined that the sale of the property is suspected of being a false sale, or that the property is likely to be abused by the crime.

The selling price payment unit 232 may register the merchandise judged to be a registerable merchandise on the platform and provide a money amount corresponding to the value of the registered merchandise to the first user side who is the seller who registered the merchandise. The selling price payment unit 232 may control to separately store the payment status of the merchandise. In accordance with various embodiments, the seller payment unit 232 writes a contract for the paid-out password to be re-returned in a transaction of the password, if the delivery for the registered sale is not performed within a predetermined time, Transactions can be performed.

The term-based rental performing unit 233 can perform the property registration and the cryptographic money lending function in the case where the first user sets the property as a collateral only for a predetermined period, and the corresponding coded money is rented for the corresponding period. The detailed description of the term-end rental performing unit 233 will be described later with reference to FIG.

Hereinafter, the registration examination unit, which is a constitution in the control unit 230, will be described with reference to FIG. 3 and FIG.

3 is a block diagram showing the configuration of the registration examination unit of FIG.

4 is a block diagram illustrating the structure of a property value evaluation unit in the registration examination unit of FIG.

3, the registration examination unit 231 may include a property value evaluation unit 2311, a false property determination unit 2312, a transaction information confirmation unit 2313, and a registration possibility evaluation unit 2314.

The selling value evaluating unit 2311 will be described with reference to FIG.

The false seller determination unit 2312 may determine whether the sale request of the first user is a false sale. For example, the false sale determination unit 2312 determines whether a first user requesting registration of a specific article is a registered blacklist member, and if the registered member is a member registered in the blacklist, . According to various embodiments, the false sale price determination unit 2312 can give a false sale price to a product that is determined to be highly false, and a false price for a sale of a user having a history recorded in the blacklist And can be given a predetermined value. In addition, according to various evaluation methods (for example, whether or not the photograph is the same as the previously registered photo, whether the product is past the expiration date, etc.), a score can be given for a false sale, It can be determined that the registered property is the property that can not be registered by the registration possibility evaluating unit 2314. [

The transaction information confirmation unit 2313 can perform an operation of confirming information related to a transaction. At this time, the transaction information may include, for example, price information of a sale inputted by the first user, transaction quantity information, and the like. In addition, according to various embodiments, the transaction information confirmation unit 2313 can confirm photographs and other explanatory information about the offer provided by the first user at the time of the sale of the property, and furthermore, Can be confirmed. The date information may indicate a deadline, and the buyer of the article may resell to another user within the deadline. The buyer of the goods may request the award of the goods within the deadline registered by the first user, even if the seller intends to present the property without reselling the property.

According to various embodiments, the transaction information confirmation unit 2313 can confirm whether or not the article delivery deadline recorded by the user has passed, in addition to the operation of confirming the article delivery date information recorded by the first user. As described above, the transaction information confirmation unit 2313 can re-execute the registration examination if the initial transaction has not yet been performed for the article that has been previously registered. If it is determined that registration is to be restricted as a result of a re-execution of the registration examination for the previously registered goods, the registration possibility evaluator 2314 may suspend the sale of the relevant article. For example, when a performance ticket in which a performance date is described is registered, after the performance date of the ticket has elapsed, the transaction information confirmation unit 2313 can determine that the sale is an invalid sale. The registration possibility evaluating unit 2314 may suspend the transaction of the article (performance ticket) based on the information confirmed by the transaction information checking unit 2313. [

The registration possibility evaluating unit 2314 can determine whether or not the corresponding article can be registered based on the information on the evaluated article in the registration judging unit 231. [ At this time, the information serving as a judgment reference may be stored in the storage unit 220 in advance.

The registration possibility evaluating unit 2314 compares the price information of the corresponding sale submitted by the first user at the sale of the seller with the value of the seller evaluated at the seller value evaluating unit 2311. If it is determined that the two values are different from each other by a predetermined value or more, 1 User can request tuning. Accordingly, if the difference between the price of the article submitted by the first user and the value evaluated by the seller value evaluating unit 2311 becomes equal to or less than a predetermined value, the registration possibility evaluating unit 2314 can reevaluate the listing as a registerable commodity.

As described above, the registration possibility evaluating unit 2314 calculates the difference between the price information evaluated by the property value evaluating unit 2311 and the price information submitted by the first user who registered the property, and based on the difference, Can be evaluated. Then, the registration possibility evaluating unit 2314 can evaluate the possibility of registration based on a false selling score of the specific sale evaluated by the false sale sale determination unit 2312 (for example, a score given in case of suspicion of a false sale). The false selling score may be given, for example, when the account of the first user has a false trading history, the account of the first user has a non-distribution history, and the like. Also, the greater the number of false transaction history and the number of non-distribution history of the first user, the greater the value of the false dealer's score.

The property value evaluation unit 2311 will be described with reference to FIG.

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

First, the field classification unit 2311a can perform an operation of classifying the sale items according to fields based on the information of the sale items requested to be registered. According to various embodiments, the classification of the sale may be set for each similar category of the degree of application of the depreciation cost. Specifically, the sector classification unit 2311a classifies two groups (for example, a gift certificate, a coupon, etc.) that are not influenced by a depreciation cost by one group (for example, (Eg antiques, limited edition products, etc.) whose value increases with the passage of time. Alternatively, the sector classification unit 2311a may designate a category of an article for each expert field of an expert who will set the value of the article. For example, the field classification unit 2311a may classify items by category, such as culture-related category, electronic product category, and fashion category.

The depreciation evaluation unit 2311b may evaluate the degree of depreciation corresponding to the elapsed time of the registration requested article. This can be calculated according to the depreciation formula for each type of stored goods (eg, it can be set to TV, refrigerator, notebook, etc.) or by category of goods (eg electronic goods, The depreciation calculation formula may be stored in the storage unit. Alternatively, the depreciation evaluating unit 2311b may calculate the depreciation calculation formula for each product by referring to the time-based transaction trend collected from the web server, and may be applied to the depreciation calculation of the corresponding product.

The booklet matching unit 2311c may match a developer who sets the value of the registration-requested article. The creator may include artificial intelligence and may be set up with multiple user accounts. The creator can preset the type or field of the article to be evaluated. Accordingly, the booklet matching unit 2311c can match a plurality of booklets corresponding to the kind or category of the requested article, and can support the prices from the booklets. Accordingly, there is an effect that the article can be evaluated by a specialist having expert knowledge about the article. For example, in the case of artwork, when the value of an artwork is valued by a person who does not have the expertise in the field, the value may be evaluated to be either too high or too low. Since expert knowledge may be required to determine the value of the article, the booklet matching unit 2311c may match the type of the requested article or the category-specific expert to the creator.

According to various embodiments, the booklet matching unit 2311c may include a portal, in which the article is traded, as the creator when the same article as the article to be valued is traded on the web.

The bookmark compensation unit 2311d may perform an operation of providing compensation to the bookmarker who has evaluated the value of the registration-requested article. In this case, the compensation can be given as the reliability score for each book account. Alternatively, the reward may be awarded with a small amount of cipher money in accordance with a transaction.

The bookmaker compensation unit 2311d may operate based on the difference between the value of the item set by the individual maker and the average value set by the individual maker when the reliability score is assigned to the bookmarker account according to various embodiments . For example, if the total number of persons is equal to or greater than a predetermined number and the average price by the entire bookmark is calculated, the bookmark compensation unit 2311d calculates a reliability score for the bookmark account having an error rate greater than a predetermined percentage from the average price A credibility score may be assigned to a booklet account that does not or does not comply with the set percent agreement. The confidence score assigned to the future sperm may also serve as a weight for pricing.

In one embodiment, the number of field-specific specialists, i.e., valuers, may be limited, and the qualifications of a valuer may only be granted to a limited number of accounts based on credibility scores. In one embodiment, the qualification of the valuator may be varied in real time based on the confidence score. In another embodiment, the qualification of the valuator may be updated at predetermined intervals and may be selected based on a vote of a block-chain participant, such as a block producer (BP) having operational credentials of a block-chained network (main net) . Depending on the embodiment, a separate vote may be made and may be substituted for a vote with a credibility score.

The predicted price calculating unit 2311e calculates the average price by summing up the estimated price information submitted by the bookmakers if the maker of the requested article matches the bookmark matching unit 2311c, can do. If it is determined that the article is affected by the depreciation cost based on the type of the article or the category information, the estimated price calculation unit 2311e calculates a second estimated price by adding a depreciation cost calculation formula to the estimated price calculated by the book owners can do.

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

5 is a block diagram showing the configuration of the term-based loan performing unit shown in FIG.

The term-based rental performing unit 233 may include an interest-based interest bookkeeping unit 2331, a property value change determining unit 2332, and an automatic sale processing unit 2333.

The periodical interest book government 2331 may calculate the amount of money that can be borrowed according to the value of the article when the first user applies for the periodical loan. Then, when the first user presents the amount to be borrowed within the borrowable amount, the interest book government 2331 of the period can receive the interest based on the loan setting period (password loan rental period) and the loan amount requested by the first user . At this time, if the value decrease rate of the secured article determined by the seller value change determination unit 2332 is equal to or greater than a preset reference value, the interest book system 2331 can control to increase and set the amount of interest have.

The selling price change determination unit 2332 can determine whether the value of the sale is changed or not, and can determine whether the value changes according to the depreciation. In addition, the seller value change determination unit 2332 may collect current market information (e.g., gold price) and determine the change in value of each product based on the collected price information.

The automatic seller processing unit 2333 can sell the corresponding property to another user when the first user can not re-deposit the cipher money so that the period set at the time of the cipher loan lapse has elapsed. At this time, when the automatic selling processing unit 2333 determines the time to sell, it is possible to refer to the quoted information of the corresponding merchandise judged by the seller value fluctuation judging unit 2332. For example, if the first user borrows a cryptogram as a collateral for gold, but delays the interest and principal for a predetermined period of time, the automatic sale processor 2333 may decide to sell the sale. However, even if the sale itself is determined at this time, the decision on the selling point can be set based on the ticker information judged by the seller value fluctuation determiner 2332. For example, when the gold price determined by the seller value fluctuation determination unit 2332 reaches a certain amount, the automatic seller processing unit 2333 can register the secured property as a sale to sell on the platform.

 FIG. 6 is a flowchart showing a procedure for a merchandise registration and a password money dispensing operation according to an embodiment of the present invention.

The controller 230 of the present invention may perform the operation 605 of receiving the merchandise registration request from the first user. The control unit 230 may then perform an operation 610 to perform an examination on the registered property. At this time, the controller 230 can determine the expected value of the sale based on the information of the sale requested. The control unit 230 may determine whether the sale is a commodity that can be traded. The commodity registration examination operation will be described in more detail with reference to FIG.

Thereafter, the control unit 230 performs an operation 615 of determining whether the sale is a sellable product. If it is determined that the sale is available for registration, the control unit 230 registers the sale as a transaction on the platform, To the first user side. In this case, the price of the sale may be price information that is actually traded, and estimated price information calculated by booksellers who are related experts.

If it is determined that the sale of the property requested by the first user is an unregistered property (for example, an illegal property or a suspected false sale), the controller 230 performs an operation to restrict the registration of the property .

FIG. 7 is a flow chart illustrating the procedure of an article registration examination operation according to an embodiment of the present invention.

The control unit 230 may perform the operation 705 of confirming the seller information and the user requested price information included in the seller registration request at the time of the seller registration examination operation. Then, the control unit 230 may perform the operation 710 of determining whether or not the information is forgery based on the sale information (for example, whether the first user's black list is registered, whether the registered sale photograph is a registered history, etc.) . At the operation step 710, it is possible to determine whether or not the product is further illegally sold. For a false sale or a sale that is judged to be illegal, registration may be restricted immediately without performing the pricing operation and subsequent operations.

Then, the controller 230 can perform the operation 715 for classifying the products into categories. The classification operation is intended to more clearly evaluate the value of the property, and may in particular be a task for requesting that the price of the property be priced for each sector.

Then, the controller 230 may perform an operation 720 of matching an area-specific price maker according to the type or category of the sale-requested listing and calculating an expected price. The upkeep controller 230 may then perform operation 725 to determine whether the field of the sale is a depreciation application field. The operation 725 may be an operation for determining whether the category of the sale is a category whose depreciation due to depreciation is equal to or greater than a preset reference value. Accordingly, when the controller 230 determines that the sale is for sale in the field where the depreciation cost is not applied according to the passage of time, the controller 230 can control the operation to proceed to 735. On the other hand, if it is determined that the article requested to be registered is an article in the field of depreciation (or an article whose value depreciation based on the depreciation cost is equal to or greater than a preset value), the controller 230 adds the depreciation cost information according to the period, The expected car price).

The controller 230 may perform the operation 735 of determining whether the difference between the estimated price of the sale and the user requested price is equal to or greater than a predetermined value. At this time, if the difference between the sales amount of the article requested by the user and the expected price of the sale calculated by the controller 230 is equal to or greater than a preset value (for example, a preset ratio), the controller 230 requests the first user to tune 740 operation. On the other hand, if the difference between the expected price of the sale and the user requested price calculated by the controller 230 is not equal to or greater than the predetermined value, the controller 230 can immediately perform operation 750 to determine that the sale is possible.

The controller 230 may perform the operation 745 of determining whether or not the request price of the first user has been tuned according to the request after the first user has requested the tuning. If the price adjustment is performed and the difference between the user requested price and the expected price of the corresponding property calculated by the controller 230 is less than a predetermined value (or ratio), the controller 230 determines that the property is a registerable property Can be performed. However, if the first user does not perform the tuning, the controller 230 may perform the operation 755 for determining that the sale is not registerable.

Although not shown in the drawings, other operations according to various embodiments of the present invention are possible. For example, the control unit 230 according to the embodiment of the present invention may grant a part of the consumer (second user) to one item of a certain category. For example, the partial acquisition may be carried out with the same concept as a kind of down payment. Accordingly, even if the second user does not pay the entire amount for the specific item, the second user can express the intention to purchase the item with only a small amount of money. If some of such acquisition operations are performed, the control unit 230 may request the second user to perform a cryptographic settlement operation for a full acquisition until a predetermined period elapses after some acquisition operations are performed.

Also, according to various embodiments of the present invention, the controller 230 receives the price and product information that the second user wants to purchase, and can match the pre-registered goods based on the received price and product information. When the second user inputs the type of the commodity desired to be acquired and the cipher money amount to be paid, the controller 230 confirms the pre-registered commodity information matching with the information input by the second user, To the second user.

When the first and second users are matched with each other, the controller 230 may transmit a message to the first user and the second user, . Accordingly, each user can receive information on the other party according to the approval of the other party (approval for the direct transaction with the matched user), thereby establishing mutual trust. As described above, according to the embodiment of the present invention, the first user and the second user can immediately match the direct transaction target person who matches the information desired by each other under the support of the control unit 230, and perform the direct transaction. Although the present invention has been described in detail with reference to the above examples, those skilled in the art will be able to make adaptations, changes and modifications to these examples without departing from the scope of the present invention. In other words, in order to achieve the intended effect of the present invention, all the functional blocks shown in the drawings are separately included or all the steps shown in the drawings are not necessarily followed in the order shown, It can be in the range.
