The configuration of the transaction mediation server 100 among the configurations of the transaction mediation system using such a block chain is shown in FIG. 2 below.

2 is a block diagram illustrating a detailed configuration diagram of a transaction mediation server of a transaction mediation system using a block chain according to an embodiment of the present invention.

Referring to FIG. 2 , the transaction mediation server 100 of the transaction mediation system using a block chain according to an embodiment of the present invention includes a communication unit 110 , a database unit 120 , a time counting unit 130 , and a control unit 140 . ) may be included.

The communication unit 110 may transmit/receive data between the purchaser device 200 and the seller device 300 . The communication unit 110 may, for example, receive a request for quotation information from the purchaser device 200 , and transmit the received request for quotation information to the seller device 300 . In addition, the communication unit 110 transmits quote information notification information to the seller device ( 300) can be sent. In this case, the estimate information notification information may be transmitted every preset time.

The database unit 120 stores buyer information (eg, name, region, business operation, purchase history, etc.), seller information (eg, name, region, business operation), estimate information, transaction information, etc. in the database It can be converted and saved.

The database 120 stores buyer information (eg, name, region, business, purchase history, etc.), seller information (eg, name, region, business), estimate information, transaction information, etc. Distributed storage over the network.

A blockchain network is a set of decentralized giant network nodes, and the nodes of the blockchain network distribute and store blockized data. Blocked data is chained and connected to each other, and blocked data cannot be arbitrarily changed or deleted.

Blocking and verification of data can be made according to the consensus algorithm of the blockchain network. For example, blockchain networks include Proof of Work (POW), Proof of Stake (POS), Proof of Authority (POA), Proof of Weight, and Byzantine Fault Tolerance ( Byzantine Fault Tolerance (BFT) can be achieved according to various consensus algorithms.

The database unit 120 may store buyer information and seller information by classifying them. More specifically, buyer information includes, for example, if the e-mail address is not a portal site address, if there is a past purchase history, if the model number or serial number of the machine sold by the seller is written in the quotation request e-mail, and if the quotation Ratings may be classified according to the case in which an attachment is attached to the request e-mail. In addition, the seller information may be classified according to, for example, when there is a transaction history, the time at which the quotation information arrives whenever there is a request for quotation, and the like. According to the seller information, the time for setting the quotation information request notification in the brokerage transaction server 100 may be set differently for each seller according to the seller information.

After the request for quotation information is received from the buyer device 200 , the time counting unit 130 transmits it to the seller device 300 , and counts for a preset time based on the time transmitted to the seller device 300 . In addition, the time counting unit 130 is a predetermined time (hereinafter, 'preset second time') if the estimate information is not received from the seller device 300 for a preset time (hereinafter referred to as 'preset first time'). ') counts the time at intervals and transmits the counting information to the control unit 140 .

The controller 140 may generally control various operations related to transaction brokerage between the buyer and the seller, and may overall control the brokerage platform provided by the brokerage transaction server 100 . Here, the intermediary platform may mean a means for using a service that the transaction intermediary server 100 can provide, such as a web page provided through a network, a smartphone application, and the like.

When a request for quotation information is received from the purchaser device 200 , the controller 140 may control the communication unit 110 to transmit the request for quotation information to the seller device 300 . In this case, the controller 140 may control to transmit the purchaser's grade and the model number or serial number of the machine to which the quotation request is made when the quotation information request information is transmitted to the seller device 300 . On the other hand, when the existing quotation information for the machine for which quotation information is requested from the purchaser device 200 is stored in the database unit 120 , the controller 140 does not request the quotation information from the seller device 300 and the database unit Existing quotation information stored in 120 may be controlled to be transmitted to the purchaser device 100 . In this case, the controller 140 may control to request approval of the seller device 300 before transmitting the existing quotation information to the purchaser device 100 . That is, the controller 140 is configured to transmit the existing quotation information to the purchaser device 100 only when there is an approval of the seller device 300 .

The controller 140 may control the operation of the time counting unit 130 by setting preset first and second times counted by the time counting unit 130 . More specifically, the controller 140 may set the first time and the second time based on the information of the seller selling the machine desired by the buyer from the database unit 120 . For example, when there is a request for quotation information, the first seller may set a preset first time to 2 hours when quotation information is received on average in two hours, and the second seller may request quotation information When the estimate information is received in 23 hours on average, the preset first time may be set to 23 hours. That is, the control unit 140 may have different time intervals for notifying that there is a request for quotation information according to seller information. Also, the preset first time and the second time may have the same value, but may have different values. For example, the first time preset to the seller may be set to 3 hours, but the second time preset to the seller may be set to 1 hour for faster delivery of quotation information.

After receiving the information indicating that the first time has been set in advance from the time counting unit 130, the control unit 140 determines that the quotation information has not been received from the seller device 300, and then quotes the seller device 300 through wired/wireless communication. The communication unit 110 may be controlled to notify the information request notification again. In this case, the control unit 140 may transmit the product number or serial number of the machine for which the quotation information is requested, and purchaser information, and the like. In addition, the quotation information request notification may be controlled to be made, for example, in an Automatic Response Service (ARS) method. The control unit 140 transmits the result of notifying the request for quotation information to the time counting unit 130, and informs the seller of the request for quotation information at the first preset time, but when it is determined that the seller has not directly received the request for quotation information The time counting unit 130 may control to count again by a preset second time period.

When the quotation information is received from the seller device 300 and transmitted to the buyer device 200 , the controller 140 pays the seller a point. In this case, the points may vary depending on the time when the quotation information is received from the seller device 300 . For example, if the quotation information is received from the seller device 300 within the first time period, the controller 140 controls to pay 100% of points to the seller device 300, and after the first time has elapsed, the second time period When the quotation information is received from the seller device 300 within, it is possible to control so that 80% of the points are paid. In this case, the controller 140 may control the seller device 300 to display the points to be acquired by the seller. That is, the controller 140 generates an alarm message so that the points to be received by the seller are displayed on the seller device 300 as an SMS message, a push alarm, etc., and the alarm message is transmitted to the seller device 300 through the communication unit 110 . can be controlled as much as possible.

In this way, the transaction brokerage system using the block chain according to an embodiment of the present invention may allow the quotation information to be delivered more quickly by paying points to the seller according to the time at which the quotation information is received.

In some embodiments, the control unit 140 may be configured to verify whether the quotation information received from the seller device 300 corresponds to valid quotation information. For example, the control unit 140 may generate average price information of the machine for which the quotation information is requested from the seller's existing quotation information stored in the database unit 120 through the block chain network. Then, the control unit 140 compares the average price information with the quotation information received from the seller device 300, and the difference between the quotation information received from the seller device 300 and the average price information falls within a preset threshold range. In this case, it may be determined that the quotation information received from the seller device 300 is valid quotation information. In this case, since a valid quotation and an invalid quotation are distinguished by the controller 140 , the seller device 300 transmitting invalid quotation information with the intention of acquiring points can be identified. Specifically, the transaction brokerage system using a block chain according to an embodiment of the present invention is characterized in that points are paid to the seller device 300 that transmits quotation information within a specific time. Certain sellers may offer quotation information at exorbitantly high prices or send invalid quotation information with the intention of earning points. However, in the transaction brokerage system using a block chain according to an embodiment of the present invention, the average price information generated from the existing quotation information stored in the database unit 120 through the block chain network and the quotation received from the seller device 300 Since invalid quotation information can be filtered by comparing the information, the above-mentioned problem can be prevented.

In some embodiments, the control unit 140 may be configured to request quotation information from the plurality of seller devices 300 , and select the lowest price quotation among the quotations received from the plurality of seller devices 300 . That is, quotation information is requested from the plurality of seller devices 300 for the same machine, and the lowest price quotation is selected from among the quotation information received from the plurality of seller devices 300 by the control unit 140, so that the buyer device ( 200) can automatically receive the lowest price quote. Accordingly, reasonable machine transaction is possible, and the success rate of machine purchase transaction can be improved.

The control unit 140 receives the quotation information from the seller device 300 and transmits the received quotation information to the buyer device 200, but if the actual purchase transaction is not made, the points paid by the buyer can be converted into cash and paid to the seller. . Accordingly, the transaction brokerage system using the block chain according to an embodiment of the present invention can compensate for the increase in the work load of the seller according to the preparation of the quotation information, so that it is possible to induce the sellers to receive the quotation information faster.

3A and 3B are flowcharts for explaining a transaction flow of a transaction brokerage system using a block chain according to an embodiment of the present invention.

Referring to FIG. 3A , in the transaction brokerage system using a block chain according to an embodiment of the present invention, first, the quotation request information for the product sold by at least one seller from the purchaser device 200 is transmitted to the transaction brokerage server 100 . is transmitted (S301). In this case, a compensation amount according to the request for quotation information may be deposited together. Here, the quotation information, for example, may include items requested by the buyer, and the items requested here may include details of products, detailed prices for each configuration, total prices, and the like.

The transaction brokerage server 100 receiving the quotation information request may provide a quotation request notification message to the seller device 300 (S302). For example, the message provision may mean that the transaction intermediary server 100 transmits to the seller device 300 via text or through an intermediary platform, and the like, and the meaning of the provision described below can be the same. Here, the message may be provided by any one of mail, text, or fax. In this case, the transaction mediation server 100 may transmit information about the purchaser and the model number or serial number of the machine together. Information about the purchaser may be graded and transmitted. As described above, if the e-mail address is not a portal site address, if there is a history of purchases in the past, if the model number or serial number of the machine sold by the seller is written in the quotation request e-mail, and a quotation Ratings may be classified according to the case in which an attachment is attached to the request e-mail. For example, if the e-mail address is not a portal site address, there is a past purchase history, and the model number or serial number of the machine is written, the customer's level may be divided into a premium level, A customer's rating with a number or serial number and past purchase history can be classified as an excellent rating.

The transaction mediation server 100 transmits a message requesting a quotation to the seller device 300 corresponding to the received quotation request (S302).

Thereafter, the transaction brokerage server 100 counts a preset time (S303). In this case, the preset time may be the first time described above. The preset first time may be a preset time based on the time when the quote information request notification message is sent to the seller device 300 . In this case, the preset first time may be set differently according to characteristics of the seller.

Thereafter, the transaction intermediary server 100 requests the quotation information again if the preset time has arrived, but the quotation information is not received from the seller device 300 (S304).

When it is confirmed that the request for quotation information has been received from the seller device 300 (S305), and a quotation is sent from the seller device 300 (S306) and transmitted to the transaction brokerage server 100, the transaction brokerage server 100 sends the quotation Reward points are paid to the provided seller (S307). In this case, the reward points may be virtual currency provided by the transaction brokerage server 100 , and may be paid to the seller in consideration of the time taken to send the quotation.

In some embodiments, the transaction mediation server 100 may check the validity of the quotation information by comparing the quotation information transmitted from the seller device 300 with the average price information generated from the existing quotation information. In addition, the transaction intermediary server 100 may transmit a request for quotation information to the plurality of seller devices 300 , and select the lowest price quotation information from among the quotation information received from the plurality of seller devices 300 .

The transaction mediation server 100 requests confirmation of purchase intention while providing the quotation information transmitted from the seller device 300 to the purchaser device 200 (S308).

Thereafter, when the purchase intention information is transmitted from the purchaser device 200 ( S309 ), the transaction intermediary server 100 transmits the purchase intention information to the seller device 300 so that a machine purchase transaction is made. At this time, the machine purchase transaction is made by discounting the compensation money deposited according to the quotation inquiry.

On the other hand, even though the quotation is sent from the seller device 300 through the transaction intermediary server 100 and delivered to the buyer device 200 , there are cases where a purchase transaction is not made.

In this regard, referring to FIG. 3B , after providing the quotation information transmitted from the seller device 300 to the purchaser device 200 ( S308 ), a non-purchase intention is transmitted from the purchaser device 200 or information on the purchase intention When not received (S311), the transaction brokerage server 100 converts the reward points into cash and pays them to the seller (S312). Accordingly, the quotation information is provided from sellers in a generally closed atmosphere, and the quotation information can be delivered more quickly.

Such a transaction brokerage system using a block chain according to an embodiment of the present invention allows a transaction to be made centered on the transaction brokerage server 100 . Accordingly, with reference to FIG. 4 , the operation flow of the transaction mediation server 100 will be described in more detail.

4 is a flowchart illustrating a transaction brokerage flow of a transaction brokerage system using a block chain according to an embodiment of the present invention. The operations of FIG. 4 may be performed by the transaction mediation server 100 of FIG. 1 .

Referring to FIG. 4 , when the transaction mediation server 100 receives a request for quotation information from the purchaser device 200 ( S401 ), it transmits the received request for quotation information to the seller device 300 ( S402 ). When the purchaser device 200 requests quotation information, the purchaser device 200 may pay a deposit according to the request for quotation information to the transaction mediation server 100 .

After that, the transaction brokerage server 100 counts a preset first time based on the point in time when the quotation information request message is delivered to the seller device 300, and when it is determined that the preset first time has been reached (S403) the seller It is determined whether the estimate information has been received from the device 300 (S404). On the other hand, the transaction brokerage server 100 counts the preset first time, and then counts until the preset first time is reached if it is determined that the preset first time has not been reached (S403). In this case, the preset first time may be different from the first time set for each seller according to the characteristics of the seller. For example, if Seller A was previously a seller who delivered quotation information within a short time, the preset first time may be later than that of Seller B, which delivers quotation information at a later time than Seller A. That is, if the first preset time for seller A is set to 3 hours based on the time when the request for quotation information is transmitted to the seller device 300 , seller B may set the first time to 2 hours.

Thereafter, when the quotation information is received from the seller device 300 , points for providing the quotation information are paid to the seller and the quotation information received from the seller is transferred to the buyer device 200 ( S405 ).

On the other hand, if the quotation information is not received from the seller device 300 even though the preset first time has been reached, the quotation information request notification is transmitted to the seller device (S406). In this case, the quotation information request notification may be notified to the seller's terminal or the seller's workplace phone in the ARS method. In this case, the quotation information may include seller information, the model number or serial number of the machine for which the quotation information is requested.

After delivering the quotation information request notification, it is determined whether the seller directly receives the quotation information request notification message (S407). If the seller directly receives the quotation information request notification message, it is determined whether the quotation information has been received (S404), and if it is determined that the quotation information request notification message has not been received due to the absence of the seller, a preset second time is counted and after a predetermined time It is determined whether the second time has been reached (S408). At this time. The second preset time may have the same value as the preset first time or may have a different value. That is, if the first time preset for the seller A is set to 3 hours, the second time set thereafter for a faster request for quotation information may be set to 1 hour intervals. In addition, if the seller does not continue to receive the quotation information request notification message, it continuously delivers the quotation information request notification message to the seller every second preset time. At this time, since the preset second time is a set time for continuously notifying the request for quotation information, a plurality of sellers may be set identically. However, the present invention is not limited thereto, and the preset first time may be set differently depending on the characteristics of the seller.

Thereafter, if it is determined that the preset second time has been reached, the quotation information request notification message is sent to the seller device 300 once again (S406), and if it is determined that the preset second time has not been reached, the seller device 300 from time to time ), it is determined whether the quotation information is transmitted and received by the transaction brokerage server 100 (S404). In this way, the transaction brokerage system using the block chain according to an embodiment of the present invention counts the first time and the second time set in advance and continuously informs the seller that there is a request for quotation information, so that faster quotation information is provided to the buyer It can speed up the transaction by allowing it to be delivered.

On the other hand, when the quotation information is received from the seller device 300 and the received quotation information is transmitted to the purchaser device 200 , it is determined whether a purchase intention for the machine for which the quotation is requested is received from the purchaser device 200 ( S409 ).

If it is determined that the purchase intention for the machine has been received from the purchaser device 200, information on the purchase intention of the purchaser is transmitted to the seller device 300 (S410) to mediate the machine transaction. On the other hand, if it is determined that the purchase intention for the machine is not received from the purchaser device 200, the points paid to the seller are converted into cash and paid to the seller (S411).
