The alcoholic beverages may be, for example, any of brewed alcoholic beverages, distilled alcoholic beverages, and mixed alcoholic beverages. Specific examples of the alcoholic beverages include sake, beer, happoshu, plum wine, shochu, chuhai, wine, whiskey, spirits, liqueur, doburoku, makgeolli, cocktails, etc. Examples of the blended alcoholic beverages include cocktails, liqueurs (mixed liquors), mixed wines made by assemblage, mixed sakes, mixed beers, mixed beers, mixed whiskeys, mixed champagnes, etc.

[0013] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. The present disclosure is not limited to the following embodiment. In each of the drawings, the same parts are given the same reference numerals. In addition, the description of each embodiment can be mutually incorporated unless otherwise specified, and the configurations of each embodiment can be combined unless otherwise specified.

[0014] [Embodiment 1] FIG. 1 is a block diagram showing an example of a configuration of a blended token trading support device 10 of the present disclosure. As shown in FIG. 1, the device 10 includes a token issuing unit 11, a market unit 12, a trading information acquiring unit 13, and a token managing unit 14. The device 10 may also include an input unit, an output unit, a display unit, and / or a storage unit, which are not shown. As shown in FIG. 1, the device 10 may be capable of communicating with a blockchain network 30, for example, via a communication line network 20, and may further be capable of communicating with a terminal 40 of a manager of a blended product and a terminal 50 of a trader of a blended token.

[0015] The device 10 may be, for example, a single device including each of the above-mentioned units, or a device to which each of the above-mentioned units can be connected via a communication line network. The device 10 may be connected to an external device described later via the communication line network. The communication line network is not particularly limited, and a known network may be used, for example, wired or wireless. Examples of the communication line network include an Internet line, a World Wide Web (WWW), a telephone line, a Local Area Network (LAN), a Storage Area Network (SAN), a Delay Tolerant Networking (DTN), a Low Power Wide Area (LPWA), and a Local 5G (L5G). Examples of wireless communication include Wi-Fi (registered trademark), Bluetooth (registered trademark), a Local 5G, and a LPWA. Examples of the wireless communication may include a form in which each device directly communicates with each other (Ad Hoc communication), an infrastructure (infrastructure communication), and an indirect communication via an access point. The device 10 may be incorporated into a server as a system, for example. Furthermore, the present device 10 may be, for example, a personal computer (PC, for example, desktop type or notebook type) in which the program of the present disclosure is installed, a smartphone, a tablet terminal, etc. The present device 10 may be in the form of cloud computing or edge computing, for example, in which at least one of the above-mentioned units is on a server and the other units are on a terminal.

[0016] 2 illustrates a block diagram of a hardware configuration of the present device 10. The present device 10 includes, for example, a central processing unit (CPU, GPU, etc.) 101, a memory 102, a bus 103, a storage device 104, an input device 105, an output device 106, a communication device 107, etc. Each part of the present device 10 is connected to each other via the bus 103 by each interface (I / F).

[0017] The central processing unit 101 cooperates with other components through a controller (such as a system controller or an I / O controller) and is responsible for overall control of the device 10. In the device 10, the central processing unit 101 executes, for example, the program disclosed herein and other programs, and also reads and writes various information. Specifically, for example, the central processing unit 101 functions as a token issuing unit 11, a market unit 12, a transaction information acquiring unit 13, and a token managing unit 14. The device 10 may include, as a computing device, other computing devices such as a CPU, a GPU (Graphics Processing Unit), an APU (Accelerated Processing Unit), or a combination of these.

[0018] The bus 103 can also be connected to, for example, an external device. Examples of the external device include an external storage device (external database, etc.), a printer, an external input device, an external display device, an external imaging device, etc. The present device 10 can be connected to an external network (the above-mentioned communication line network) by, for example, a communication device 107 connected to the bus 103, and can also be connected to other devices via the external network.

[0019] An example of the memory 102 is a main memory (primary storage device). When the central processing unit 101 performs processing, the memory 102 reads various operation programs, such as the program of the present disclosure, stored in the storage device 104 described below, and the central processing unit 101 receives data from the memory 102 and executes the program. The main memory is, for example, a RAM (random access memory). The memory 102 may also be, for example, a ROM (read only memory).

[0020] The storage device 104 is also called an auxiliary storage device, for example, in contrast to the main memory (primary storage device). As described above, the storage device 104 stores an operating program including the program of the present disclosure. The storage device 104 may be, for example, a combination of a recording medium and a drive that reads and writes from the recording medium. The recording medium is not particularly limited, and may be, for example, an internal or external type, such as a HD (hard disk), CD-ROM, CD-R, CD-RW, MO, DVD, flash memory, and memory card. The storage device 104 may be, for example, a hard disk drive (HDD) in which a recording medium and a drive are integrated, and a solid state drive (SSD). When the present device 10 includes the storage unit, for example, the storage device 104 functions as the storage unit. The memory unit can store, for example, information about the manager and trader of the blended product (identification information (e.g., name or title, address, telephone number, ID, etc.), attribute information (e.g., gender, age, organization, address, contact information, hobbies, preferences, etc.), biometric information, etc.), token issuance request information, blended product identification information, blended tokens, blended target identification information, blended target tokens, transaction information, owner information, selection instruction information, product management instruction information, management information, shipping request information, and shipping instructions, etc.

[0021] In the present device 10, the memory 102 and the storage device 104 can also store various information such as log information, information acquired from an external database (not shown) or an external device, information generated by the present device 10, and information used when the present device 10 executes processing. In this case, the memory 102 and the storage device 104 may store, for example, the above-mentioned information on the user of the present device. Note that at least a portion of the information may be stored, for example, in an external server other than the memory 102 and the storage device 104, or may be distributed and stored in multiple terminals using block chain technology or the like.

[0022] The device 10 further includes, for example, an input device 105 and an output device 106. The input device 105 may be, for example, a pointing device such as a touch panel, a track pad, or a mouse; a keyboard; an imaging means such as a camera or a scanner; a card reader such as an IC card reader or a magnetic card reader; or an audio input means such as a microphone. The output device 106 may be, for example, a display device such as an LED display or a liquid crystal display; an audio output device such as a speaker; a printer; or the like. In the present disclosure 1, the input device 105 and the output device 106 are configured separately, but the input device 105 and the output device 106 may be configured as an integrated device, such as a touch panel display.

[0023] Next, an example of the blended token trading support method of the present disclosure will be described based on the flowchart of Fig. 3. The blended token trading support method of the present disclosure is implemented as follows, for example, using the device 10 of Fig. 1 or Fig. 2. Note that the blended token trading support method of the present disclosure is not limited to use of the device 10 of Fig. 1 or Fig. 2.

[0024] The token issuing unit 11 issues a blended token on the blockchain for each blended product identification information linked to a blended product obtained by mixing at least one blending object (S1, token issuing step). The blended token is, for example, a non-fungible token (NFT) linked 1:1 to the blended product identified by the blended product identification information. The NFT has a unique identifier for enabling distinction from other NFTs, and therefore can have a unique value distinguished from other NFTs. Specifically, the token issuing unit 11 can issue the blended token on the blockchain by storing the blended token in each node 31 of the blockchain network 30 connected to the device 10 via the communication line network 20. The token issuing unit 11 may, for example, further record information on the blended product linked to the blended token in the blockchain network 30. The information on the blended product may include, for example, the name and quantity of the blended product. The token issuing unit 11 may store the blended token in the memory 102 or the storage device 104, for example. In this case, the token issuing unit 11 may store blended product identification information of the blended product corresponding to the blended token, for example, in association with the blended token. Note that in FIG. 1, each node 31 of the blockchain network 30 is described as a terminal different from the blended product manager's terminal 40 and the trader's terminal 50, but some or all of the blended product manager's terminal 40 and the trader's terminal 50 may function as the node 31 of the blockchain network 30.

[0025] The token issuing unit 11 may issue the blended token based on, for example, token issuing request information. The token issuing request information is, for example, information requesting the issue of a blended token from a person who wishes to issue a blended token (also referred to as an issue requester) to the present device 10, and includes blended product identification information of alcoholic beverage products. The issue requester may be, for example, a blended product manager (for example, a blended product manufacturer, seller, distributor, etc.), or an owner of a blended target token to be described later in embodiment 2. The blended product identification information is information for identifying the blended product. The blended product is, for example, as described above. The blended product identification information is not particularly limited as long as it is information that can identify (specify) the blended product, and may be, for example, a manufacturing number (lot number), a name of the blended product, etc. In this case, the token issuing unit 11 may acquire the token issuing request information from, for example, the terminal 40 of the blended product manager (issue requester) in FIG. 1, or may acquire the token issuing request information by input from the manager of the present device 10 who has received information from the blended product manager. The token issuing unit 11 may, for example, obtain the token issuance request information directly from the terminal 40, or may obtain the token issuance request information indirectly. In the latter case, the token issuing unit 11 may obtain the token issuance request information from, for example, a server device or storage that obtains and accumulates the token issuance request information output by the terminal 40.

[0026] The token issuance request information may include, for example, trading information. The trading information is, for example, information for trading the blended token with a trader via the market unit 12 described below. The trading information includes, for example, identification information of the blended token to be traded, provider identification information, price information of the blended token, information on whether the price can be changed, a trading period, information on a blended product identified by blended product identification information linked to the blended token, and the like. As a specific example of the information on the blended product, in the case where the blended product is a blended alcoholic beverage obtained by blending (mixing) alcoholic beverage products, the information includes, for example, the name of the blended alcoholic beverage, the blending conditions, and information on the blended products used in the blending. The information on the blended product is, for example, information on the blended alcoholic beverage products used in the blending, and includes information such as the product name, alcohol content, information on the production location (e.g., production area, manufacturer (brewery), etc.), information on the manufacturing method (e.g., raw materials, rice polishing ratio, variety, etc.), information on the taste (e.g., sweetness, sourness, sake meter value, etc.), volume, date of manufacture, product appearance (e.g., container photo), product description, etc. The provider identification information is, for example, information for identifying the provider of the blended product, and may include information such as the store name, product information (type of product, price), delivery method, name, nickname, address, telephone number, email address, ID, identification number, and identification information of the terminal owned by the provider of the alcoholic beverage (e.g., serial number, IMEI (International Mobile Equipment Identity), IP address, MAC address, etc.).

[0027] The token issuing unit 11 may issue a blended token on the blockchain for each of the blended objects. The issuance of the blended token can be performed in the same manner as the issuance of the blended token, except that the blended object is the blended product instead of the blended product.

[0028] The blended token and the blended token may include, for example, an additional program that enables additional functions. The additional program is not particularly limited, and may be, for example, a program for realizing a mechanism for adding a part of the distribution price as a fee to the manager of the device 10 and the manager of the blended product when the blended token is circulated. The blended token and the blended token may further include, for example, images such as illustrations and content information such as music.

[0029] Next, the market unit 12 publishes the blended token in the market (S2, market step). In addition, the market unit 12 may publish the blended token in the market, for example, when the blended token has been issued. Specifically, the market unit 12 can publish the blended token and the blended token in the market by, for example, transmitting the blended token and the blended token to a general blockchain marketplace via a communication line network. In addition, the market unit 12 may, for example, further transmit trading information to the blockchain marketplace. The trading information is, for example, information necessary for trading NFTs in the blockchain market. The trading information may be, for example, information included in the token issuance request information acquired in S1, or may be information stored in the memory 102 or storage device 104 of the present device 10. As a specific example, for example, an administrator of the blended product who uses the present device 10 may register an account to be used when using the present device 10, and part or all of the trading information may be linked to the account and stored. The market unit 12 may have a function as the blockchain marketplace by itself, for example. In this case, the market unit 12 of the present device 10 may be, for example, a device independent of the other units of the present device 10 as a market (store) server. In this case, the market (store) server can communicate with, for example, a device having the other units of the present device 10. In addition, when the market unit 12 has the marketplace function, the payment of the price may be made by the present device 10, or may be made separately outside the present device 10. In the former case, for example, the present device 10 may include a payment unit, and in this case, the payment unit acquires transaction price information of the blended token and the blended token based on transaction information described later, transmits the transaction price information to a payment server outside the device, and acquires the settlement result by the payment server, thereby executing the payment process. In addition, the payment process is not particularly limited, and for example, various methods in known payment devices can be used.

[0030] The market unit 12 may have a market function for reselling the blended token and the blended token, for example. In this case, the market unit 12 can obtain listing information of the blended token and the blended token from the owners of the blended token and the blended token, and publish the listing information on the market. The listing information can include, for example, information for identifying the blended token and the blended token that the owner wishes to resell, the owner's identification information (name, nickname, address, telephone number, email address, ID, identification number, identification information of the terminal owned by the manager of the blended product or the manager of the device 10 (for example, serial number, IMEI (International Mobile Equipment Identity), IP address, MAC address, etc.)), price information, and selection instruction information to be described later.

[0031] Next, the transaction information acquisition unit 13 acquires transaction information of the blended token and the blended token in the market (S3, transaction information acquisition step). The transaction information is, for example, information on the transaction of the blended token and the blended token in the blockchain marketplace, and includes, for example, the trader (for example, seller, purchaser), transaction date and time, transaction location, the blended token and the blended token that are the subject of the transaction, and the transaction price. The transaction information may also include, for example, selection instruction information described later in embodiment 3. The transaction information acquisition unit 13 can acquire the transaction information, for example, from a server device that constructs the blockchain marketplace. In addition, when the market section 12 of the present device 10 has a function as a blockchain marketplace, the transaction information may be acquired from the market section 12. When the market section 12 has a market function for resale, the transaction information acquisition unit 13 may acquire, for example, transaction information of the blended token and the blended token in the market based on the listing information. The transaction information acquisition unit 13 may store the acquired transaction information in the memory 102 or the storage device 104, for example.

[0032] Next, the token management unit 14 updates the owner information of the blended token and the blended token on the blockchain based on the transaction information (S4, token management step). For example, based on the transaction information, the token management unit 14 can register the information of the purchaser of the blended token and the blended token as the owner information in the blockchain network 30. In addition, when the blended token and the blended token that already have an owner are put up for sale on the market section 12 and the blended token and the blended token are purchased by another trader, the token management unit 14 registers the purchaser of the traded blended token and the blended token as a new owner in the blockchain network 30. The registration of information in the blockchain network 30 can be, for example, the same as in the S1 step. As a result, the owners of the blended token and the blended token can be registered in the blockchain network 30, so that the owner of the product identified by the product identification information linked to the blended token and the blended token can be clarified.

[0033] The token management unit 14 may, for example, link the blend token and record blend record information of the blended product in the blockchain. The blend record information is information on the blend history of the blended product. The blend record information includes, for example, information on the type of blending target products blended into the blended product, the blending ratio of the blending target products, the blending conditions, the blending amount, and the like. The blending conditions include, for example, temperature, blending method, equipment (container) used for blending, blending time, information on the mixer, and the like. The token management unit 14 may, for example, acquire blend designation information described later in embodiment 2 as the blending record information, or may acquire a record entered by a person who produced the blended product by blending the blending target products (for example, the manager of the blended product) as the blending record information.

[0034] According to the blended token trading support device of the present disclosure, a blended token linked 1:1 to a blended product identified by blended product identification information can be issued, and the transaction of the blended token can be recorded by a blockchain network. In addition, the blended token issued by the blended token trading support device of the present disclosure is linked 1:1 to a blended product identified by the blended product identification information, for example. Therefore, according to the blended token trading support device of the present disclosure, by trading the blended token, it is possible to indirectly trade the blended product. The blended token has a 1:1 relationship with the blended product identification information, and the transaction history and information on the blended product linked to the blended token can also be recorded in the blockchain network. Therefore, it is possible to guarantee the authenticity and value of the blended product being traded.

[0035] In addition, according to the blended token transaction support device of the present disclosure, it is possible to record blend record information in a blockchain in association with the blended token. Therefore, according to the blended token transaction support device of the present disclosure, the authenticity of the blended product can be guaranteed.

[0036] [Embodiment 2] The second embodiment is another example of the blended token transaction support device of the present disclosure.

[0037] The blended token trading support device of the present disclosure is similar to the blended token trading support device 10 of the above-mentioned embodiment 1, except that it includes a blending designation information acquisition unit and a blending instruction unit in addition to the configuration of the blended token trading support device 10 of embodiment 1, and the description thereof can be used. The blended token trading support device 10A of the present disclosure includes, for example, a blending designation information acquisition unit and a blending instruction unit, the blending designation information acquisition unit acquires blending designation information, the blending designation information being information for designating at least two types of blended target tokens to manufacture a blended product, the blending instruction unit outputs blending instruction information for manufacturing a blended product by blending the blended objects based on the blending designation information, the token issuing unit acquires blended product identification information linked to the blended blended product based on the blending instruction information, and issues a blended token on the blockchain for each of the blending identification information, and the token management unit updates information on the blockchain of the blended target token linked to the blended target product designated by the blending designation information based on at least one of the blending designation information and the blending instruction information.

[0038] Fig. 4 is a block diagram showing an example of the configuration of a blended token trading support apparatus 10A of the present disclosure. As shown in Fig. 4, the blended token trading support apparatus 10A includes a blending designation information acquisition unit 15 and a blending instruction unit 16 in addition to the configuration of the blended token trading support apparatus 10 of embodiment 1. The hardware configuration of the blended token trading support apparatus 10A is the same as that of the blended token trading support apparatus 10 of Fig. 2, except that the central processing unit 101 has the configuration of the blended token trading support apparatus 10A of Fig. 4 instead of the configuration of the blended token trading support apparatus 10 of Fig. 1.

[0039] Next, an example of the blended token trading support method of the present disclosure will be described based on the flowchart of Fig. 5. The blended token trading support method of the present disclosure is implemented as follows, for example, using the device 10A of Fig. 4. Note that the blended token trading support method of the present disclosure is not limited to use of the device 10A of Fig. 4. Also, S11 to S14 in the following description may be executed simultaneously with S1 to S4 in the first embodiment, or may be executed sequentially or in parallel, for example.

[0040] The blending specification information acquisition unit 15 acquires, for example, blending specification information (S11, blending specification information acquisition step). The blending specification information is, for example, information for manufacturing a blended product by specifying at least two types of blending target tokens. The blending specification information includes, for example, information such as blending target tokens (types of blending target products to be blended) specified by the user, the mixing ratio of the specified blending target products, mixing conditions, mixing amount, and unit filling amount of the blended product after blending. The mixing conditions include, for example, temperature, mixing method, equipment (container) used for mixing, mixing time, information of the mixer, and the like. The unit filling amount is, for example, the amount per container when the blended blended product is filled into a container after blending. The unit filling amount may be, for example, an amount selected from at least one of a specified amount specified by the present device 10A, or may be an amount that can be arbitrarily set by the user. The present device 10A may propose an appropriate unit filling amount, for example, from the remaining quantity of the blending target products specified by the blending target tokens specified in the blending specification information, the mixing ratio, and the mixing amount. The appropriate unit filling amount may be, for example, an amount that maximizes the number of filling units of the blended product, or an amount that relatively reduces the amount of waste of the blended product. The blending designation information may include, for example, user identification information that identifies the user. The blending designation information acquisition unit 11 may acquire the blending designation information from at least one of the trader and the owner of the blended token, for example. The blending designation information acquisition unit 11 may acquire the blending designation information input by a user during a transaction process of the blended token in the marketplace, or may acquire blending designation information input (purchased) separately by a user who trades the blended token and has ownership of the blended token. In this way, the blending designation information acquisition unit 11 can acquire, for example, the blending designation information. The blending designation information may be, for example, selection instruction information that a trader can select (purchase) during a transaction of the blended token.In this case, the market unit 12 may display, for example, a button that allows the user to select whether or not to make the blended token to be published a blend target when publishing the blended token on the market. The blending designation information acquisition unit 11 may, for example, link the acquired blending designation information to the blended token linked to the designated blending target product and store it in the memory 102 or the storage device 104. The token management unit 14 may, for example, link the acquired blending designation information to the blended token and store it on the blockchain.

[0041] The blending instruction unit 16 outputs blending instruction information for producing a blended product by blending the blending objects based on the blending designation information (S12, blending instruction step). The blending instruction information is information for producing a blended product by blending a plurality of blending objects linked to the blending object tokens included in the blending designation information according to the blending conditions, and is also called blending recipe information. The output destination of the blending instruction information may be, for example, a manager of the blending objects, a manager of the present device 10A, a custodian of the blending objects, or a manufacturer of the blended object.

[0042] Specifically, the blend instruction unit 16, for example, refers to the blending target token designated by the blending designation information, and identifies the current manager of the blending target product linked to the designated blending target token. Then, the blend instruction unit 16, for example, outputs the blending instruction information to the manager of the blending target product. The managers of the blending target product to which the blending instruction information is output (the provider, the manager, the custodian) blend the blending target products according to the blending conditions included in the blending instruction information to manufacture the blended product. For example, when there are multiple current managers of the blending target products identified based on the blending designation information, the blend instruction unit 16 outputs the blending instruction information to each manager. In this case, the blending instruction information may be, for example, information instructing a manufacturer of the blended product to transport the amount of the blending target products designated in the blending designation information. Then, the blend instruction unit 16, for example, further outputs the blending instruction information to the manufacturer of the blended product. Then, the manufacturer of the blended product who receives the blending instruction information and the blending target product blends the blending target products according to the blending instruction information to manufacture the blended product.

[0043] The token issuing unit 11, for example, acquires blended product identification information linked to the blended product blended based on the blending instruction information, and issues a blended token on the blockchain for each of the blending identification information (S13, token issuing step). The token issuing step of S13 is similar to S1 of the first embodiment, except that the blended product identification information is the blending identification information of the blended product blended based on the blending instruction information output in S12. Specifically, first, the token issuing unit 11 acquires blended product identification information of the blended product blended based on the blending instruction information, for example. The blended product identification information may be identification information issued by the manager of the blended product or the manufacturer of the blended product, or may be identification information issued by the token issuing unit 11 based on information such as the quantity of the blended blended product. Then, the token issuing unit 11 can generate a blended token by linking it to the blending identification information for each of the blended products, for example. The market unit 12, for example, publishes the blended token in a market. The market may be the same as the market in the S2 step of the first embodiment, or may be different.

[0044] In addition, the token issuing unit 11 may, for example, link the blended token with at least one of the blending designation information and the blending instruction information, and record the blending record information of the blended product in the blockchain. This allows, for example, the blending history of the blended token to be recorded in the blockchain, and the authenticity of the blended product can be guaranteed.

[0045] The token management unit 14 updates the information on the blockchain of the blended token linked to the blended product specified in the blending designation information based on at least one of the blending designation information and the blending instruction information (S15, token management step). When the owner of the blended token designates the blended product and instructs the production of the blended product, the quantity of the blended product linked to the blended token is reduced or eliminated. For this reason, the token management unit 14 refers to the quantity of the blended product used in the production of the blended product in at least one of the blending designation information and the blending instruction information, and writes the quantity of the blended product linked to the blended token to the information on the blockchain. In addition, when the entire amount of the blended product linked to the blended token is consumed in the production of the blended product, the token management unit 14 may delete the blended token from the blockchain.

[0046] The blended token trading support device of the present disclosure includes, for example, a blending designation information acquisition unit and a blending instruction unit, the blending designation information acquisition unit acquires blending designation information, the blending designation information being information for producing a blended product by specifying at least two types of blended target tokens, the blending instruction unit outputs blending instruction information for producing a blended product by blending the blending objects based on the blending designation information, the token issuing unit acquires blended product identification information linked to the blended blended product based on the blending instruction information and issues a blended token on the blockchain for each of the blending identification information, and the token management unit can update information on the blockchain of the blended target token linked to the blended product specified by the blending designation information based on at least one of the blending designation information and the blending instruction information.

[0047] The owner or trader of the blended token can produce a blended product even if he does not own the actual product to be blended, by outputting a manufacturing instruction for the blended product to the manufacturer of the blended product via the blended token trading support device of the present disclosure. Furthermore, according to the blended token trading support device of the present disclosure, at least one of the blending designation information and the blending instruction information can be recorded in the blockchain linked to the blended token as blending record information of the blended product produced by the instruction of the user. Furthermore, as a blending record of the blended product, information of the user who inputted the blending designation information can be recorded in the blockchain linked to the blended token after blending. Therefore, according to the blended token trading support device of the present disclosure, the creator of the blending recipe of the blended product can be recorded on the blockchain. As a result, the blended token trading support device of the present disclosure can be expected to have the effect of, for example, guaranteeing that the creator of the blended recipe is truly the creator of the blended recipe.

[0048] The value of a blended product may be greatly increased by blending it to become a blended product. For example, whiskey or aged sake (for example, so-called aged sake) may have a higher value than the original whiskey or aged sake (blended product) by adjusting the taste and aroma of the blended whiskey or blended sake (blended product). However, it is difficult to compare the value of the blended product with the value of the blended product, and it is difficult to evaluate the value of the blended product compared to the blended product. According to the blended token trading support device of the present disclosure, blended tokens for each blended product and blended tokens for each blended product obtained by blending the blended products are traded in the market. Therefore, according to the blended token trading support device of the present disclosure, the market value of the blended product and the market value of the blended product from which it is blended can be visualized. In addition, according to the blended token trading support device of the present disclosure, the difference between the market value of the blended product and the market value of the blended product from which it is blended can be calculated, thereby visualizing the new value created by blending the blended products.

[0049] In addition, conventionally, it is difficult for a manufacturer (blender) of a blended product to objectively show the value created by manufacturing the blended product, and there is a problem that the value is only evaluated by an ambiguous evaluation such as whether the blender is famous or unknown, not by the value that the blender himself can create. The blended token transaction support device of the present disclosure can, for example, record blending record information by linking it to the blended token. Since the blending record information includes blending designation information, by referring to the blending record information, it is possible to track the blended objects constituting the blended product linked to the blended token, the market value of the blended objects (the trading price in the market of the blended object token), the user who issued the blending instruction for the blended product, and the like. Therefore, according to the blended token transaction support device of the present disclosure, for example, a user can record and prove the blended value of the blended product that he created (the difference between the market value of the blended product and the market value of the blended object that was the source of the blending). Therefore, according to the blended token transaction support device of the present disclosure, for example, a manufacturer (blender) of a blended product that is a user can show the blended value of the blended product that he created to others with objective grounds.

[0050] [Embodiment 3] The third embodiment is another example of the blended token transaction support device of the present disclosure.

[0051] The blended token trading support device of the present disclosure is similar to the blended token trading support device 10A of the above-mentioned embodiment 2, except that it includes a selection instruction information acquisition unit and an instruction information output unit in addition to the configuration of the blended token trading support device 10A of embodiment 2, and the description thereof can be used. The blended token trading support device 10B of the present disclosure includes, for example, a selection instruction information acquisition unit and an instruction information output unit, and the selection instruction information acquisition unit acquires selection instruction information regarding at least one of the blended product and the blended products from the trading information, and the instruction information output unit generates instruction information based on the selection instruction information and outputs the instruction information to an administrator of at least one of the blended product and the blended products.

[0052] Fig. 6 is a block diagram showing an example of a configuration of a blended token trading support apparatus 10B of the present disclosure. As shown in Fig. 6, the blended token trading support apparatus 10B includes a selection instruction information acquisition unit 17 and an instruction information output unit 18 in addition to the configuration of the blended token trading support apparatus 10A of embodiment 2. The hardware configuration of the blended token trading support apparatus 10B is similar to that of the blended token trading support apparatus 10 of Fig. 2, except that the central processing unit 101 has the configuration of the blended token trading support apparatus 10B of Fig. 6 instead of the configuration of the blended token trading support apparatus 10 of Fig. 1.

[0053] Next, an example of the processing of the selection instruction information acquisition unit 17 and the instruction information output unit 18 of the blended token trade support apparatus 10B of the present disclosure will be described with reference to the flowchart in Fig. 7. S21 to S22 in the following description may be executed simultaneously with, sequentially, or in parallel with, for example, S1 to S4 in the first embodiment and S11 to S13 in the second embodiment.

[0054] The selection instruction information acquisition unit 16 acquires selection instruction information related to at least one of the blended product and the blended product from the transaction information (S21, selection instruction information acquisition step). The selection instruction information acquisition unit 16 may acquire the selection instruction information input by a user during the transaction processing of the blended token and the blended target token in the marketplace, for example, or may acquire selection instruction information separately input (purchased) by a user who has traded the blended token and the blended target token. In this way, the selection instruction information acquisition unit 16 can acquire, for example, the selection instruction information included in the transaction information. For example, the selection instruction information acquisition unit 16 may associate the acquired selection instruction information with the corresponding blended token and blended target token and store it in the memory 102 or the storage device 104. In addition, the token management unit 14 may associate the acquired selection instruction information with the corresponding blended token and blended target token and store it on the blockchain.

[0055] The selection instruction information is information that a user (trader) can additionally select when trading blended tokens and blended tokens in the marketplace. Specifically, the selection instruction information may be, for example, information regarding the handling (management, storage conditions, delivery) of the blended product and blended product.

[0056] The selection instruction information includes, for example, information specifying the storage conditions of the blended product and the products to be blended (storage temperature, storage location, storage period). The information on the storage state may be, for example, information specifying in detail the storage conditions (management conditions) such as temperature, humidity, brightness of the storage location, storage containers, and the like, storage period, or information specifying a category of the storage state (management state) such as freezing, quick freezing (also called flash freezing), refrigeration, room temperature, aging, and the like. In the latter case, it is preferable that the device 10B stores in its storage unit, for example, a combination of the category of the storage state and the corresponding detailed information on the storage conditions for each type of the blended product and the products to be blended.

[0057] The selection instruction information may include, for example, information regarding the delivery of the blended product and the blended product (delivery company, delivery time, delivery conditions (temperature conditions such as refrigerated, frozen, room temperature, etc.), delivery location, etc.). The information regarding the delivery of the blended product and the blended product may be acquired simultaneously with information specifying the storage conditions of the blended product and the blended product, or may be acquired separately. In the latter case, the selection instruction information including information regarding delivery is also referred to as delivery request information, for example. The owner of the blended token and the blended token may be able to request delivery at any time for the blended product and the blended product linked to the blended token and the blended token that he / she owns, or may be able to request delivery only within the expiration date of the blended token (blended token) that is set in advance.

[0058] Next, the instruction information output unit 17 generates instruction information based on the selected instruction information, and outputs the instruction information to a manager of at least one of the blended product and the blending target products (S22, instruction information output step).

[0059] When the selection instruction information includes information specifying the storage conditions of the blended product and the blending target product, the instruction information output unit 17 can generate, for example, product management instruction information based on the selection instruction information as the instruction information. Specifically, when the selection instruction information includes detailed information on the storage conditions of the blended product and the blending target product, the instruction information output unit 17 can generate the storage conditions as the instruction information. When the selection instruction information is information specifying a category of the storage conditions, the instruction information output unit 17 can, for example, refer to the storage unit, refer to the storage conditions linked to the category of the storage conditions corresponding to the blended product and the blending target product purchased by the purchaser, and generate and output information on the storage conditions as the instruction information. The output destination of the instruction information may be, for example, a provider of the alcoholic beverage product, an administrator of the device 10B, a delivery company, or a custodian of the alcoholic beverage product. It is preferable that the delivery company and the custodian are, for example, persons designated by the administrator.

[0060] The manager of the blended product and the blended product to which the instruction information is output (e.g., the provider, the custodian, etc.) can change the storage state of the blended product and the blended product based on the instruction information. The change of the storage state may be performed, for example, by the manager himself, or by another person (e.g., a delivery company, a distributor, a storage company) who receives an instruction from the manager. The manager can transmit information on the storage state of the blended product and the blended product to the device 10 as management information, for example, by his own terminal (terminal 40). The instruction information output unit 17 of the device 10 can, for example, acquire the transmitted management information and output the management information by linking it to the corresponding blended token. The output may be directly output to the terminal of the provider, trader, purchaser, etc., or may be output so as to be viewable on the blockchain marketplace. This allows the purchaser of the blended token or the blended token to check the management information of the blended product and the blended product via the device 10B. However, without being limited to this, for example, the present device 10B may acquire storage information of the corresponding blended products and blended products as the management information by using cameras and various sensors installed in the storage facilities for the blended products and blended products.

[0061] When the selection instruction information includes information regarding the delivery of the blended product and the blending target products, the instruction information output unit 17 generates, for example, delivery instructions based on the selection instruction information and outputs the delivery instruction information. Specifically, the instruction information output unit 17 generates delivery instructions for arranging the delivery of the blended product and the blending target products based on, for example, information regarding the delivery of the blended product and the blending target products (delivery company, delivery time, delivery conditions (temperature conditions such as refrigerated, frozen, room temperature, etc.)), delivery location, etc.). Then, the instruction information output unit 17 can output the delivery instructions to terminals of the provider, the manager, the delivery company, the warehouse management company, the distributor, etc.

[0062] The manager of the blended product and the blended product that received the instruction information, for example, arranges for the delivery of the blended product and the blended product based on the delivery instruction. The delivery arrangement may be made by the manager himself, or by another person (for example, a delivery company, a distributor, a storage company) that receives an instruction from the manager. The manager can transmit information on the delivery status of the blended product and the blended product to the device 10 as management information, for example, from his own terminal (terminal 40). The instruction information output unit 17 of the device 10 can, for example, acquire the transmitted management information and output the management information by linking it to the corresponding blended token. The output may be directly output to the terminal of the provider, trader, purchaser, etc., for example, or may be output so as to be viewable on the blockchain marketplace. This allows the purchaser of the blended token or the blended token to check the delivery status of the blended product and the blended product via the device 10B.

[0063] As a specific example, the following will explain a case where the blended product and the blended product are sake, and a sake brewery, which is an alcohol provider, uses device 10B to generate an NFT for a sake product (sake NFT) and support trading of alcohol products through the sake NFT; however, the present disclosure is in no way limited to the following explanation.

[0064] First, a person wishing to issue a sake NFT (for example, an employee of a sake brewery that is the alcohol provider, or an administrator of this device 10 who has received a request from the alcohol provider) accesses this device 10, for example, with his / her own terminal 40, and inputs token issuance request information related to the produced sake to request the issuance of a sake NFT. FIG. 8 shows an example of a screen displayed on the terminal 40 that has accessed this device 10. Note that the example screen shown in FIG. 8 is an example, and does not limit the present disclosure in any way. A person wishing to issue a sake NFT can request the issuance of a sake NFT by, for example, inputting the necessary information for each item (product image, product name, product description, link to details page, detailed information, Collection, number of editions, Blockchain, etc.) as the token issuance request information on the screen shown in FIG.

[0065] The device 10 issues sake NFTs in a one-to-one correspondence with the product identification information on the blockchain. The device 10 then uses the market unit 12 to publish the registered sake NFTs on the blockchain marketplace. FIG. 9 shows an example of a screen of the NFT market published by the device 10, but the screen example shown in FIG. 9 is merely an example and does not limit the present disclosure in any way. As shown in FIG. 6, the published sake NFTs can be searched, for example, by the function of the marketplace, and are displayed in a list by a user's search operation. The search is not particularly limited, and examples include keyword search, price search, tag search, etc. The marketplace may also have, for example, a tag search function, a sorting function, a filter function, etc. The marketplace may also have, for example, a function of tallying and displaying the number of views and the number of likes for each sake NFT. The marketplace may also have, for example, a function of ranking and displaying sake NFTs based on the trading performance of sake NFTs (volume, price, price fluctuation range, number of views, number of likes, etc.). At this time, the tally for displaying the rankings can be calculated based on conditions such as the type of blockchain, place of production, and trading period.

[0066] A trader who wishes to purchase sake via this device 10 can access the blockchain marketplace published by this device 10 using his or her own terminal 50 and view the sake NFTs that have been published as shown in FIG. 9. If the trader then wishes to purchase the viewed sake NFT, the trader performs a purchase process for the sake NFT on the blockchain marketplace. When a published sake NFT is purchased on the blockchain marketplace, this device 10 obtains transaction information for the sake NFT from the blockchain marketplace, and based on the transaction information, updates the owner information of the alcohol NFT on the blockchain network from the alcohol provider to the trader.

[0067] Furthermore, when the trader selects the storage condition of the sake as flash freezing for 10 years as the selection instruction information when purchasing the sake NFT, the present device 10 acquires the selection instruction information. The present device 10 then generates and outputs instruction information instructing the sake product corresponding to the purchased sake NFT to be flash frozen and stored frozen for 10 years. As described above, the output may be from the administrator of the present device 10 or the producer of the sake product (brewery). The administrator or brewery then ships the sake product to a flash freezing facility based on the instruction information, flash freezes the sake product at the flash freezing facility, and stores it in a frozen warehouse. The owner or manager of the flash freezing facility may be the same as or different from the administrator or brewery of the present device 10, but it is preferable that the facility is managed by the administrator of the present device 10. The present device 10 can also acquire management information on the storage condition of the sake product from the frozen warehouse and output it so that it can be viewed on the blockchain marketplace. The management information includes, for example, the sake NFT's identification number (token ID), storage location, shipping deadline, date of receipt, and delivery status.

[0068] When the trader trades sake NFTs that he or she owns via the device 10, the trader accesses the device 10 using his or her terminal 50 and inputs listing information for the blockchain marketplace. The market section 12 of the device 10, for example, publishes the listing information on the blockchain marketplace. This allows the trader to trade sake NFTs that he or she owns via the device 10.

[0069] When the trader needs to deliver a sake product linked to a sake NFT he or she owns, the trader accesses the device 10 using his or her terminal 50 and inputs information regarding the delivery of the sake product as the selection instruction information. When the device 10 acquires the selection instruction information regarding the delivery, it generates delivery instructions based on the selection instruction information and outputs the delivery instructions to a terminal of a warehouse manager who manages the cold storage warehouse. The warehouse manager performs shipping processing of the alcoholic beverage product corresponding to the sake NFT based on the delivery instructions. This allows the trader to deliver the sake product linked to the sake NFT he or she owns.

[0070] When the blended product is an alcoholic beverage product, it is generally known that the value of the alcoholic beverage product varies greatly depending on its storage conditions. On the other hand, even if the alcoholic beverage product is the same, how to evaluate the value of the alcoholic beverage product based on its storage conditions varies greatly depending on the preferences and values ​​of the consumer of the alcoholic beverage product. Specifically, for example, even if the same alcoholic beverage is produced at the same manufacturing plant, one consumer may highly value fresh alcohol immediately after production, while another consumer may highly value alcohol that has been aged over the years. However, the ability to select the storage and management conditions of the alcoholic beverage product (for example, whether to flash freeze fresh alcohol immediately after production or to store it for aging, etc.) is usually limited to the manufacturer of the alcoholic beverage product, and traders of the alcoholic beverage product have no room to intervene in the storage and management conditions of the alcoholic beverage product. The present disclosure also enables traders of blended tokens to specify the category of storage state as selection instruction information even in such cases. Therefore, according to the present disclosure, a trader who purchases a blended token will be able to choose, for example, to flash-freeze some of the alcoholic beverages to ensure value for consumers who prefer fresh alcohol, and age some of the alcoholic beverages to ensure value for consumers who prefer aged alcohol, making it possible to maintain and manage the asset value of the alcoholic beverages in a more stable state.

[0071] Furthermore, among alcoholic beverages, for example, wine increases in trading price over time, so that the trading price increases with secondary distribution, and the value as an asset increases. In contrast, compared to wine, the value as an asset of sake, beer, plum wine, shochu, etc. is not stable, and since there is no secondary distribution market, the trading price is unlikely to rise, and profitability is low. Therefore, the blend token trading support device of the present disclosure issues blend tokens for these alcoholic beverage products, and after the blended product manager sells them, resale is performed between other traders via the blend token, so that the final sales price can be expected to increase. In this case, if the blend token has, as the additional function, for example, a function of adding a part of the distribution price as a fee to the manager of the device 10B or the provider of the alcoholic beverage when the blend token is circulated, profitability can be further improved. Furthermore, compared to wine, sake often has a low market price for its product quality, so the blend token trading support device of the present disclosure is suitable for supporting transactions of sake products via blend tokens.

[0072] [Embodiment 4] The program of the present disclosure is a program for causing a computer to execute each step of the blended token trading support method described above. Specifically, the program of the present disclosure is a program for causing a computer to execute a token issuance procedure, a market procedure, a transaction information acquisition procedure, and a token management procedure.

[0073] The token issuing step includes issuing a blend token on a blockchain for each blended product identification information associated with a blended product obtained by mixing at least one blending object, The market procedure includes publishing the blended token to a market; The transaction information acquisition step acquires transaction information of the blended token in the market, The token management procedure updates the owner information of the blended token on the blockchain based on the transaction information.

[0074] The program of the present disclosure can also be said to be a program that causes a computer to function as a token issuing procedure, a market procedure, a transaction information acquisition procedure, and a token management procedure.

[0075] The program of the present disclosure may be incorporated with reference to the description of the blended token transaction support device and the blended token transaction support method of the present disclosure. In each of the steps, for example, the "step" may be replaced with "processing". In addition, the program of the present disclosure may be recorded, for example, in a computer-readable recording medium. The recording medium is, for example, a non-transitory computer-readable storage medium. The recording medium is not particularly limited, and examples thereof include random access memory (RAM), read-only memory (ROM), hard disk (HD), flash memory (for example, SSD (Solid State Drive), USB flash memory, SD / SDHC card, etc.), optical disk (for example, CD-R / CD-RW, DVD-R / DVD-RW, BD-R / BD-RE, etc.), magneto-optical disk (MO), floppy (registered trademark) disk (FD), etc. In addition, the program of the present disclosure (for example, also referred to as a programming product or program product) may be, for example, in a form distributed from an external computer. The "distribution" may be, for example, distribution via a communication network or distribution via a device connected by a wire. The program of the present disclosure may be installed and executed on the device to which it is distributed, or may be executed without being installed.
