  Hereinafter, an embodiment for implementing a generation program, a generation apparatus, and a generation method according to the present application (hereinafter referred to as “embodiment”) will be described in detail with reference to the drawings. Note that the generation program, the generation apparatus, and the generation method according to the present application are not limited by the embodiment. In the following embodiments, the same portions are denoted by the same reference numerals, and redundant description is omitted.

[1. Example of generation process)
First, an example of the generation process according to the embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a diagram (1) illustrating an example of a generation process according to the embodiment. Specifically, FIG. 1 illustrates a flow in which the generation process according to the present application is performed by the generation apparatus 100 that is an information processing terminal controlled by the generation program according to the present application. More specifically, in FIG. 1, a smart contract that is a program indicating a contract such as a commercial transaction in a platform using a block chain is generated by the generation device 100 that is an example of a generation device according to the present application. The flow of processing will be described.

  In the embodiment, a predetermined platform using a block chain is referred to as a block chain network 50. It is assumed that the block chain network 50 has a unique virtual currency system, and is a network capable of dealing with virtual currency. For example, the blockchain network 50 may be an existing platform such as Ethereum.

  The smart contract in the block chain network 50 is a contract made on the block chain network 50. Specifically, the smart contract is a program that is described in a digital format and automatically executes processing according to preset contents when the conditions set as contract contents are achieved. For example, the user can generate a commercial contract for exchanging virtual currency in the blockchain network 50 by generating a smart contract.

  As is well known, the block chain has a mechanism for maintaining the reliability of information without requiring a central management system or the like. For this reason, by generating a smart contract, a user can perform a commercial transaction between users without using a server or the like that mediates the commercial transaction. For example, the user can generate a smart contract by describing the product name, the price of the product, conditions arbitrarily set by the user regarding the transaction, and the like. However, the smart contract may have a unique format for each platform, and there are many points that are difficult for a general user to generate. Even if a smart contract is generated, if the business transaction generated by the smart contract is not well known among users, a situation may occur in which the transaction is not established.

  Therefore, the generation apparatus 100 according to the present application generates a smart contract that can set arbitrary conditions even by a general user by the process described below, and also notifies the generated smart contract to other users. It is possible to make it. Hereinafter, the flow of generation processing according to the present application will be described with reference to FIGS. 1 and 2. Hereinafter, the smart contract may be simply referred to as a contract.

  FIG. 1 shows an example in which information is exchanged among the generation apparatus 100, the web server 30, and the block chain network 50. The generation device 100 is an information processing terminal that generates a contract. In the example illustrated in FIG. 1, the generation apparatus 100 is used by a seller in a commercial transaction, that is, a user U01 who desires to generate a contract in the blockchain network 50 and sell a product. The generation device 100 is, for example, a smartphone or a tablet terminal.

  The web server 30 is a server device that provides a user with a service page such as a web page. Specifically, when the web server 30 receives access from the information processing terminal, the web server 30 provides web page data to the information processing terminal. The information processing terminal displays a web page on the screen using browser software or the like.

  The web server 30 according to the embodiment is, for example, a server that provides SNS (Social Networking Service). In this case, the web server 30 receives a message posted from the user and reflects the received message on a web page that is newly provided to the user.

  The block chain network 50 is a predetermined platform that uses block chain technology. The block chain network 50 does not have a centrally managed system or the like, but has a distributed system that is processed by a plurality of computers existing on the network. The block chain network 50 has its own virtual currency. In the block chain network 50, when a contract is generated, a contract is established, or a contract is approved, a virtual currency is transferred.

  In the example shown in FIG. 1, the user U01 desires to generate a contract. Specifically, the user U01 desires to generate a contract indicating a commercial transaction for selling the product in the blockchain network 50 by setting a price for the product held by the user U01. In this case, the user U01 inputs information related to the commercial transaction desired by the user U01 to the generation apparatus 100.

  The generation apparatus 100 receives information on a contract desired to be generated from the user U01. For example, the generation apparatus 100 receives input of identification information (for example, a product name) for identifying a transaction target in a commercial transaction, price information set for the transaction target, conditions for the transaction, and the like as information on the contract. In this case, the generation device 100 may display a predetermined user interface or the like on the screen and accept an input from the user U01 via the user interface.

  In the contract of the block chain network 50, the user U01 can arbitrarily set the price set as a transaction target and the conditions for the transaction. For example, as a condition in the transaction, the generation device 100 determines whether or not the business partner (the user who is a buyer of the product) has a predetermined number of business establishment results in the past, or whether the business partner has made a past transaction establishment with the user U01. And whether or not the business partner has a transaction establishment record of a predetermined amount or more in the past. By including such a condition in the contract, the user U01 can make a transaction only with a user having a certain level of reliability, and thus the reliability of the transaction can be increased.

  The generation device 100 generates a contract based on information about the contract received from the user (step S11). Specifically, the generation device 100 generates a script described in a programming language that can be used in the blockchain network 50 based on information on the contract. Hereinafter, data related to the contract generated by the generation apparatus 100 may be referred to as “contract data”.

  Then, the generation apparatus 100 transmits (uploads) the generated contract data on the block chain network 50 (step S12). In the block chain network 50, the contract data transmitted from the generation device 100 is verified by a plurality of computers that construct a distributed system (generally called mining in the block chain technology). When the contract data is verified, the contract is registered on the block chain network 50. Then, an address (contract address) for specifying the contract is issued on the block chain network 50 (step S13).

  The generating apparatus 100 receives the contract address issued on the block chain network 50 (step S14). The generation apparatus 100 stores the received contract address and the generated contract in association with each other.

  Here, the generation apparatus 100 performs a process of generating a predetermined code including information on the generated contract and the contract address. As described above, even when a contract is registered on the blockchain network 50, if the contract information is not known to other users, the possibility that the contract is established is reduced. Therefore, the generation device 100 generates a predetermined code that allows another user to access the contract by including a contract address that is information for specifying the contract.

  In this case, it is desirable that the code for allowing other users to access the contract is generated in a manner that can be easily seen by many users. Therefore, the generation device 100 generates a code in a form that can be posted in a predetermined network service. For example, in the SNS service provided by the web server 30, the generation device 100 generates a code in such a manner that it can be posted on a message posted by the user U01.

  Specifically, the generating apparatus 100 generates a posting QR code (registered trademark) that can be displayed on the service page as a predetermined code (step S15). The QR code generated by the generation device 100 includes, for example, a contract address issued for a script (contract data) transmitted to the block chain network 50 and information (contracts of commercial transactions) about the contract approved on the block chain network 50. Content) etc.

  The generation device 100 uploads the generated QR code to the service page provided by the web server 30 according to the operation of the user U01 (step S16). For example, the user U01 posts a QR code on a service page together with a message that advertises a product. The web server 30 posts the uploaded QR code on a predetermined service page (step S17).

  As described above, the generation apparatus 100 receives information on a contract desired to be generated from the user U01. And the production | generation apparatus 100 produces | generates the contract which can be enforced on the block chain network 50 based on the information regarding the accepted contract. Furthermore, the generating apparatus 100 generates a QR code including information related to the contract and a contract address for accessing the contract.

  That is, the generating apparatus 100 can generate a contract desired by the user U01 without imposing a burden on the user U01. Moreover, since the generation apparatus 100 can increase the opportunity to make the contract known to other users by generating a code indicating the contract in a manner that can be posted on the service page, it facilitates transactions between individuals. Can do.

  Next, a flow of processing in which the QR code generated by the generation device 100 is used by another user will be described with reference to FIG. FIG. 2 is a diagram (2) illustrating an example of the generation process according to the embodiment. In FIG. 2, a flow of processing in which the user U02 who is a buyer in a commercial transaction performs the commercial transaction indicated in the contract using the terminal device 200 will be described.

  The terminal device 200 that is an information processing terminal accesses a service page provided by the web server 30 in accordance with an operation by the user U02 (step S21). The terminal device 200 is, for example, a smartphone or a tablet terminal.

  The web server 30 distributes the accessed service page to the terminal device 200 (step S22). It is assumed that the QR code generated by the generation device 100 is posted on the distributed service page.

  When the user U02 selects a QR code included in the service page, the terminal device 200 reads the QR code information (step S23). The QR code includes a contract address corresponding to the contract generated by the generation device 100. For this reason, the terminal device 200 accesses the contract indicated by the contract address when the QR code is selected from the user U02.

  The terminal device 200 acquires the information regarding the contract by accessing the contract on the block chain network 50 (step S24). And the terminal device 200 displays the information regarding the acquired contract on a screen. For example, the terminal device 200 displays the product in the contract and the price set for the product.

  Here, it is assumed that the user U02 desires to purchase a product displayed on the terminal device 200. For example, the user U02 indicates an intention to purchase by selecting a button or the like indicating purchase of a product displayed on the screen. When the user U02 performs a product purchase operation, the terminal device 200 transmits a product purchase request to the block chain network 50 (step S25).

  In the block chain network 50, the request for purchase of the product transmitted by the terminal device 200 is verified. When the request is verified, the contract is executed assuming that the contract has been established (step S26). At this time, the generation apparatus 100 receives a notification that the generated contract has been executed. Then, the user U01 confirming the notification sends a product corresponding to the contract to the user U02.

  Thereafter, the user U02 receives the product sent from the user U01. The user U02 confirms that there is no difference between the sent product and the product indicated in the contract, and then operates the terminal device 200 to perform a product receipt confirmation process (step S31). Specifically, the terminal device 200 receives information indicating confirmation of receipt of the product by selecting a button indicating the receipt of the product from the user U02 on the screen indicating the contract corresponding to the product.

  The terminal device 200 transmits confirmation information to the block chain network 50 (step S32). On the block chain network 50, verification information transmitted from the terminal device 200 is verified.

  When the verification information is verified, the contract is established on the block chain network 50. Then, on the block chain network 50, a process of moving the virtual currency for the price set in the contract from the user U02 to the user U01 is executed (step S33). Thereby, a series of processes related to the contract generated by the generation apparatus 100 is completed. The virtual currency transfer process in step S33 may use a different method for each of various virtual currencies. For example, when the user U02 makes a purchase request, the virtual currency corresponding to the price is transferred on the contract (a record of the transfer is recorded on the block chain), and when the contract is established, the contract is made to the user U01 from the contract. A method in which remittance is performed may be used.

  As described above, the generation apparatus 100 generates a contract for a commercial transaction desired by the user U01 and generates a QR code indicating the content of the contract. Thereby, the production | generation apparatus 100 can notify the transaction which concerns on the contract which the user U01 produced | generated to the user U02 who is another user who browses a service page. Thus, according to the production | generation apparatus 100, the flexible personal transaction between users can be promoted.

  Note that the generation device 100 can realize the above-described processing by an arbitrary method. For example, the user U01 may install a generation program that performs the above-described generation process in advance as an application (application) executed by the generation apparatus 100. In this case, the generation apparatus 100 receives the application activation operation from the user U01 and executes the generation program. Also, processing such as QR code reading and product purchase request performed by the terminal device 200 may be executed by a dedicated application. Further, the generation program itself may be described in various arbitrary program languages. Hereinafter, the generation apparatus 100 that executes the above-described generation process according to such a generation program will be described in detail.

The generation apparatus 100 is not limited to a smartphone or a tablet terminal, but may be a desktop PC, a notebook PC, a PDA (Personal Digital Assistant), a wearable terminal, or the like.

  The terminal device 200 is an information processing device used by a user who desires to browse a service page or use a commercial transaction in the block chain network 50. For example, the terminal device 200 is a desktop PC, a notebook PC, a tablet terminal, a mobile phone, a PDA, a wearable terminal, or the like.

  The web server 30 is a web server that distributes service pages such as web pages. For example, the web server 30 is a portal site, news site, auction site, weather forecast site, shopping site, finance (stock price) site, route search site, map providing site, travel site, restaurant introduction site, SNS site, web blog. A web page including various information related to the above is distributed to the generation apparatus 100.

  The web page distributed by the web server 30 is formed by, for example, an HTML file described in HTML, an XML file described in XML (Extensible Markup Language), or the like. The web page distributed by the web server 30 may include an advertisement acquisition command. For example, in an HTML file or the like forming a web page, a URL of a predetermined advertisement server is described as an advertisement acquisition command. In this case, the generation apparatus 100 acquires advertisement content from a predetermined advertisement server by accessing a URL described in an HTML file or the like.

  The block chain network 50 is a predetermined platform that uses block chain technology. As described above, in the blockchain network 50, a user can generate a contract on the network N, so that a commercial transaction or the like via an original virtual currency can be performed.

[3. Configuration of the generator
Next, the configuration of the generation apparatus 100 according to the embodiment will be described with reference to FIG. FIG. 4 is a diagram illustrating a configuration example of the generation apparatus 100 according to the embodiment. As illustrated in FIG. 4, the generation device 100 includes a communication unit 110, an input unit 120, an output unit 125, a storage unit 130, and a control unit 140.

The storage unit 130 according to the embodiment includes a contract table 131 as a data table in which information about the contract is stored.

  FIG. 5 shows an example of information stored in the contract table 131. FIG. 5 is a diagram illustrating an example of the contract table 131 according to the embodiment. In the example shown in FIG. 5, the contract table 131 includes items such as “contract ID”, “contract address”, “product ID”, “transaction amount”, “condition”, “QR code data”, and “transaction establishment”. Have.

  “Contract ID” indicates identification information for identifying a contract. The “contract address” indicates an address for specifying a contract on the block chain network 50.

  “Product ID” indicates identification information for identifying the product that is the object of the contract transaction. The “transaction amount” is a price set for the product, and indicates the amount by which the virtual currency is transferred when the contract is established. The unit of the numerical value of the transaction amount shown in FIG. 5 is assumed to be a unit of virtual currency handled by the block chain network 50.

  “Condition” indicates a condition arbitrarily set by the user in the transaction. “QR code data” indicates QR code data generated by the generation device 100 after a contract is generated and a contract address is issued. The QR code includes information such as the contents of the contract, the contract address, and conditions.

  The QR code may include various information other than the above. For example, the QR code may include a link to a page that introduces a product in detail (for example, a service page provided by a user who is a product seller). For example, the QR code may include a link to a page that stores product image data.

  “Transaction established” indicates whether or not a transaction has been established for the contract held in the contract table 131. For example, if the item “confirmed transaction” is “0”, it indicates that the transaction has not yet been completed. On the other hand, if the item “confirmed transaction” is “1”, it indicates that the transaction has been completed.

  That is, in the example of the information illustrated in FIG. 5, the contract identified by the contract ID “C10” is the contract address “A10”, and is a contract whose transaction is the product identified by the product ID “G10”. It is shown that. In addition, the transaction amount in the contract is “100”, and the condition that the user of “10 or more transactions completed” or the user of “cumulative transaction amount 1000 or more” is set as a transaction partner is set. Show. Furthermore, a QR code is generated for the contract, and the contract indicates that a transaction has not yet been established.

  Returning to FIG. 4, the description will be continued. The control unit 140 is a controller, for example, various programs (for example, a generation program according to the present application) stored in an internal storage device by a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or the like.

Each processing unit included in the control unit 140 corresponds to each procedure executed by the generation program according to the present application. For example, the process executed by the reception unit 141 corresponds to a reception procedure that the generation program causes the generation apparatus 100 to execute.

  The reception unit 141 receives information on a contract desired to be generated from the user. For example, the reception unit 141 receives information regarding the contract from the user via a predetermined user interface or the like.

  For example, the reception unit 141 includes at least one of identification information for identifying a transaction target, information indicating a link destination to detailed data of the transaction target, price information in the transaction, or conditions in the transaction as information on the contract. Accept.

  Specifically, the reception unit 141 displays the product name of the product to be traded, the name of the service to be traded, link information to the image data of the product, the amount of virtual currency set as the transaction target, and the like. Accept.

For example, the first generation unit 142 includes information that identifies the generation apparatus 100 that generated the contract (script), the creator who created the generation program itself according to the present application, the provider that provided the generation program as an application, and the like. Generate a script. Thereby, it can be proved that the contract corresponding to the script is generated by a program provided from a certain reliable generation source. Such identification information may be, for example, signature information signed by a secret key issued by a provider who provided the generation program as an application.

  The receiving unit 143 receives various information. For example, the receiving unit 143 receives information on the contract registered in the block chain network 50 and information on the issued contract address.

  The display control unit 144 controls display on the output unit 125. For example, when the receiving unit 143 receives the contract address, the display control unit 144 displays a button or the like indicating whether or not to generate a QR code on the output unit 125 (that is, on the screen of the generating apparatus 100). Control the display. In response to the user selecting a displayed button, the second generation unit 145 described later performs a QR code generation process.

  Note that the display control unit 144 also performs control such that a button for receiving a selection from the user is appropriately displayed on the screen in the reception process by the reception unit 141 and the transmission process by the transmission unit 147 described later. May be. That is, the display control unit 144 may perform processing related to various user interfaces in the generation apparatus 100.

Further, when receiving a message including a QR code generated by the generation device 100, the distribution unit 35 distributes a web page reflecting the received information to the terminal device 200.

[5. (Processing flow of generator)
Next, a processing procedure performed by the generation apparatus 100 according to the embodiment will be described with reference to FIG. FIG. 8 is a flowchart illustrating a processing procedure performed by the generation apparatus 100 according to the embodiment.

  As illustrated in FIG. 8, the generation apparatus 100 determines whether information regarding a contract has been received from the user (step S <b> 101). When the information regarding the contract is not received, the generation device 100 waits until the information is received (step S101; No).

  On the other hand, when the information regarding a contract is received (step S101; Yes), the production | generation apparatus 100 produces | generates a contract (step S102). Then, the generation apparatus 100 transmits the generated contract data to the block chain network 50 (Step S103).

  Thereafter, the generation device 100 receives a contract address corresponding to the contract registered in the block chain network 50 (step S104). And the production | generation apparatus 100 produces | generates QR code containing the information regarding a contract, and a contract address (step S105).

[6. (Modification)
The processing according to the above-described embodiment may be performed in various different forms other than the above-described embodiment. Hereinafter, another embodiment of the generation processing system 1 will be described.

[6-1. Processing by server)
In the above embodiment, the generation apparatus 100 is a terminal that the user U01 has, and for example, an example in which generation processing is performed via an application that operates on the terminal has been described. However, the generation apparatus 100 may be a server installed on a network instead of a terminal. This point will be described with reference to FIGS. FIG. 9 is a diagram (1) illustrating an example of the generation process according to the modification.

  The generation apparatus 100 according to the modified example has a configuration similar to the configuration illustrated in FIG. Further, when functioning as a server, the generation device 100 may perform a process of providing a service page, like the web server 30. In this case, the generation apparatus 100 may further have a configuration similar to that of the web server 30 illustrated in FIG. 7 in addition to the configuration of FIG.

  When the generating device 100 is a server, the user U21 who is a seller (exhibitor) of the product requests the generating device 100 to generate a contract via the exhibitor terminal 300 used by the user U21.

  That is, the exhibitor terminal 300 transmits exhibition data such as a commodity desired to be exhibited, a consideration for the commodity, conditions, and the like in accordance with the operation of the user U21 (step S41). In other words, the exhibitor terminal 300 transmits information regarding the contract that the user desires to generate to the generation apparatus 100.

  The generation device 100 generates a contract based on the received information (step S42). And the production | generation apparatus 100 transmits the contract data regarding the produced | generated contract to the block chain network 50 (step S43). On the block chain network 50, the contract is registered and the contract address is issued (step S44). Then, the generation apparatus 100 receives the contract address issued on the block chain network 50 (step S45).

  And the production | generation apparatus 100 matches the received contract address and the produced | generated contract, and posts the said contract on a service page. That is, the generating apparatus 100 lists the products that the user U21 has listed on the service page (step S46). For example, when the generation device 100 provides a shopping site for performing transactions between individuals, the product that the user U21 has listed is listed as a product that has been listed on the shopping site. In this case, the generating apparatus 100 does not have to generate the QR code corresponding to the contract.

  Next, a flow when the product is purchased from the user U02 will be described with reference to FIG. FIG. 10 is a diagram (2) illustrating an example of the generation process according to the modification.

  The terminal device 200 requests purchase of the listed product according to the operation of the user U02 (step S51). When the generation apparatus 100 receives a purchase request from the terminal apparatus 200, the generation apparatus 100 transmits the purchase request to the block chain network 50 (step S52). In the block chain network 50, a contract corresponding to the purchase request is executed (step S53). The generation apparatus 100 receives a notification indicating that the contract has been executed on the block chain network 50 (step S54).

  And the production | generation apparatus 100 transmits the notification which shows that the contract was performed to the exhibitor terminal 300 which is an exhibitor (step S55). The user U21 who is the exhibitor who received the notification sends the product to the user U02.

  Thereafter, the user U02 confirms that the product sent from the user U21 is not different from the product indicated in the contract, and then operates the terminal device 200 to perform confirmation processing for receipt of the product (step S61). The terminal device 200 transmits confirmation information to the generation device 100 (step S62). The generation device 100 transmits the confirmation information received from the terminal device 200 to the block chain network 50 (step S63). On the block chain network 50, verification information transmitted from the generation device 100 is verified.

  When the verification information is verified, the contract is established on the block chain network 50. Then, on the block chain network 50, a process of moving the virtual currency for the price set in the contract from the user U02 to the user U21 is executed (step S64). Thereby, a series of processes regarding the contract generated by the generation apparatus 100 according to the modification is completed.

  As described above, the generation program executed by the generation apparatus 100 not only functions as an application in the terminal, but can perform the same function even when the generation apparatus 100 is a server. Thereby, even if the production | generation apparatus 100 is a case where the production | generation processing system 1 contains various deformation | transformation, it can promote the flexible personal transaction between users.

[6-2. Service page)
In the above-described embodiment, an example in which the QR code generated by the generation device 100 is posted on the service page is shown. However, the QR code may be posted on any medium.

  For example, the QR code may be posted as an advertisement content displayed on an application provided to a smartphone or an advertising space included in a service page. In this case, the user can access the contract corresponding to the QR code by selecting or reading the QR code displayed as the advertisement content. In this case, the generation processing system 1 may include an advertisement distribution server in addition to the web server 30.

[6-3. contract〕
In the blockchain network 50, it has been described that the contract can be arbitrarily set by the user. Specifically, in the embodiment, it has been described that the user can freely select a desired product to generate a contract or set the amount of consideration.

  Here, in addition to the above information, the user can arbitrarily set the contract. For example, the contract may describe a time limit for performing the transaction, a shipping fee related to the transaction, a condition related to the cancellation, and the like. That is, the generation apparatus 100 receives such information as information related to the contract, and generates a contract reflecting the information. Thereby, the production | generation apparatus 100 can produce | generate the contract according to a user's hope. In addition, said information is an example and the production | generation apparatus 100 may accept | permit arbitrarily from a user about various information generally set by the transaction between individuals, an auction site, etc. generally.

[6-4. conditions〕
The generation apparatus 100 may accept conditions other than those exemplified in the above embodiment as the conditions related to the contract. For example, the generation apparatus 100 may accept attribute information of a user who is a partner of a transaction as a condition. For example, the generation device 100 may accept conditions such as the user's age, sex, and residence. Thereby, since the user who uses the production | generation apparatus 100 can specify the conditions regarding the other party of a transaction arbitrarily, it can trade more reliably between individuals.

[6-5. Use of past information)
When generating the contract, the generating apparatus 100 may perform a predetermined process based on information on the contract generated in the past. For example, the generation apparatus 100 acquires contract history information generated so far in each terminal or the like. Specifically, the generation apparatus 100 acquires information about a contract when the same product as the product that the user is trying to sell is listed via the network N.

  And the production | generation apparatus 100 displays the information regarding the past contract as a recommendation, when a user tries to produce | generate the contract regarding the said goods. For example, the generation device 100 provides the user with information such as the value set for the product in the past contract and the amount of the value when the transaction is established. Thereby, even if it is a case where it is a case where it is utilized from the user unfamiliar with transaction, the production | generation apparatus 100 can produce | generate the contract in which the appropriate conditions were set. As described above, the generation device 100 can perform generation processing with high usability.

[6-6. Use of transaction history)
In the above-described embodiment, the generation apparatus 100 has, as a condition in the transaction, that the business partner has a predetermined number of transaction establishment results in the past, that the business partner has a transaction establishment history in the past with the user, or It has been shown that at least one of the past having a transaction establishment record of a predetermined amount or more may be accepted.

  The generation apparatus 100 confirms the transaction history on the block chain when accepting the condition using the transaction history in this way. For example, in the technology related to the block chain, the generation apparatus 100 can confirm the past transaction record by a method of scanning the block backward and confirming the record of the supplier.

  Specifically, when the generation apparatus 100 accepts a transaction condition, the generation device 100 scans a block of a past transaction of a business partner on the block chain, and checks a source code (script) for checking whether there is a predetermined transaction record. Generate. For example, when the condition is that “10 or more transactions have been established”, the generation apparatus 100 can trace back the transaction and satisfy the condition that 10 or more transactions have been established. It is determined that the user has a certain trust. In this case, the generation apparatus 100 determines that the user is permitted to purchase, for example, by performing processing that activates a purchase button in the transaction. On the other hand, for a user who does not satisfy the conditions, the generation apparatus 100 performs processing such as deactivating a purchase request from the user, making the QR code unreadable, or excluding the product listing. Can do.

  That is, the first generation unit 142 according to the generation device 100 determines whether or not the condition is satisfied by scanning a block on a predetermined network using the block chain according to the condition received by the reception unit 141. Generate a contract that contains a script to do. Thereby, the generation device 100 can accurately determine a user who satisfies the received condition. As for a script (program) for scanning a block, an existing script for each platform using a block chain may be used, or a script that conforms to the platform specifications may be generated in real time. Good.

  Note that the generation apparatus 100 may perform determination on the application instead of scanning a transaction on the block chain for determining the above condition. For example, when a user performs a transaction through an application provided by the generation device 100, a transaction history is stored on the application. The generation device 100 refers to the transaction history of the terminal used by the trading partner when the user sets the condition that the trading partner has completed the transaction 10 times or more when listing the product. It is determined whether or not the condition that the transaction has been completed is satisfied. When the condition is satisfied, the generation apparatus 100 performs processing such as activating a purchase button in the transaction.

  That is, the first generation unit 142 according to the generation device 100 determines whether or not the condition is satisfied based on the history regarding the transaction recorded in the terminal device used by the business partner according to the condition received by the reception unit 141. Generate a smart contract that contains a script to do. Also with this method, the generation apparatus 100 can accurately determine a user who satisfies the received condition.

[6-7. program〕
It has been described that the processing by the generation apparatus 100 described above is realized by the generation program according to the present application. For example, the first generation unit 142 according to the generation device 100 is realized by the CPU, the MPU, or the like included in the generation device 100 executing the first generation procedure according to the generation program using the RAM as a work area. The Similarly, the other processing units related to the generation apparatus 100 are realized by executing each procedure by the generation program.

  Here, the processing executed by the generation device 100 according to the present application may not necessarily be realized by the generation program. For example, the process of displaying information by the display control unit 144 may be executed by an OS (Operating System) included in the generation apparatus 100. That is, the generation program itself does not execute all the processes executed by the generation apparatus 100 as described above, but the generation program has been described above using data executed or acquired by the OS. The processing may be realized.

[7. Others]
In addition, among the processes described in the above embodiment, all or part of the processes described as being automatically performed can be performed manually, or the processes described as being performed manually can be performed. All or a part can be automatically performed by a known method. In addition, the processing procedures, specific names, and information including various data and parameters shown in the document and drawings can be arbitrarily changed unless otherwise specified.

  Further, each component of each illustrated apparatus is functionally conceptual, and does not necessarily need to be physically configured as illustrated. In other words, the specific form of distribution / integration of each device is not limited to that shown in the figure, and all or a part thereof may be functionally or physically distributed or arbitrarily distributed in arbitrary units according to various loads or usage conditions. Can be integrated and configured. For example, the reception unit 141 and the reception unit 143 illustrated in FIG. 4 may be integrated.

  In addition, the above-described embodiments and modifications can be combined as appropriate within a range that does not contradict processing contents.

[8. Hardware configuration)

  The CPU 1100 operates based on a program (for example, a generation program according to the present application) stored in the ROM 1300 or the HDD 1400, and controls each unit. The ROM 1300 stores a boot program executed by the CPU 1100 when the computer 1000 is started up, a program depending on the hardware of the computer 1000, and the like.

  The HDD 1400 stores a program executed by the CPU 1100, data used by the program, and the like. The communication interface 1500 receives data from other devices via the network N and sends the data to the CPU 1100, and transmits data generated by the CPU 1100 to other devices via the network N.

  The CPU 1100 controls an output device such as a display and a printer and an input device such as a keyboard and a mouse via the input / output interface 1600. The CPU 1100 acquires data from the input device via the input / output interface 1600. Further, the CPU 1100 outputs the data generated via the input / output interface 1600 to the output device.

  The media interface 1700 reads a program or data stored in the recording medium 1800 and provides it to the CPU 1100 via the RAM 1200. The CPU 1100 loads such a program from the recording medium 1800 onto the RAM 1200 via the media interface 1700, and executes the loaded program. The recording medium 1800 is, for example, an optical recording medium such as a DVD (Digital Versatile Disc) or PD (Phase change rewritable disk), a magneto-optical recording medium such as an MO (Magneto-Optical disk), a tape medium, a magnetic recording medium, or a semiconductor memory. Etc.

  For example, when the computer 1000 functions as the generation apparatus 100 according to the embodiment, the CPU 1100 of the computer 1000 implements the function of the control unit 140 by executing a program loaded on the RAM 1200. The HDD 1400 stores data in the storage unit 130 included in the generation apparatus 100. The CPU 1100 of the computer 1000 reads these programs from the recording medium 1800 and executes them. However, as another example, these programs may be acquired from other devices via the network N.
