The blending target products are, for example, items that are mixed (blended) when producing the blended product, and may be finished products or intermediate products. Note that in the present disclosure, the blended product may be, for example, a blending target product for producing a new blended product. As a specific example, when the blended product is an alcoholic beverage (blended alcoholic beverage), the alcoholic beverage (blended product) that serves as the raw material for the blended alcoholic beverage is not particularly limited as long as it is, for example, a beverage containing alcohol. The alcoholic beverage may be, for example, a brewed alcoholic beverage, a distilled alcoholic beverage, or a mixed alcoholic beverage. Specific examples of the alcoholic beverages include sake, beer, happoshu (low-malt beer), plum wine, shochu, chuhai, wine, whiskey, spirits, liqueur, doburoku (unrefined sake), makgeolli (rice wine), cocktails, etc. Examples of the blended alcoholic beverages include cocktails, liqueurs (mixed alcohol), blended wines made by assemblage, blended sakes, blended beers, blended whiskeys, blended champagnes, etc.

[0013] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. The present disclosure is not limited to the following embodiments. In the following drawings, the same parts are denoted by the same reference numerals. Furthermore, the descriptions of the embodiments can be mutually incorporated unless otherwise specified, and the configurations of the embodiments can be combined unless otherwise specified.

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

[0015] The device 10 may be, for example, a single device including the above-described units, or a device in which the units can be connected via a communication network. The device 10 can also be connected to an external device (described later) via the communication network. The communication network is not particularly limited and any known network can be used, for example, a wired or wireless network. Examples of the communication network include the Internet, the 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 Network (LPWA), and a Local 5G (L5G). Examples of wireless communication include Wi-Fi (registered trademark), Bluetooth (registered trademark), Local 5G, and LPWA. Examples of the wireless communication include direct communication between devices (Ad Hoc communication), infrastructure communication, and indirect communication via an access point. The device 10 may be incorporated into a server as a system. Furthermore, the present device 10 may be, for example, a personal computer (PC, for example, desktop or notebook type) on 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 located on a server and the other units are located on a terminal.

[0016] 2 shows a block diagram of the hardware configuration of the device 10. The 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, and a communication device 107. The components of the device 10 are connected to each other via the bus 103 and their respective interfaces (I / F).

[0017] The central processing unit 101 operates in cooperation with other components via 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 of the present disclosure and other programs, and also reads and writes various types of 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 other computing devices such as a CPU, a GPU (Graphics Processing Unit), an APU (Accelerated Processing Unit), or a combination of these as a computing device.

[0018] The bus 103 can also be connected to, for example, external devices. Examples of the external devices include an external storage device (such as an external database), a printer, an external input device, an external display device, and an external imaging device. The device 10 can be connected to an external network (the 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] The memory 102 may be, for example, a main memory (primary storage device). When the central processing unit 101 performs processing, the memory 102 reads various operating programs, such as the program of the present disclosure, stored in the storage device 104 (described later), and the central processing unit 101 receives data from the memory 102 and executes the programs. The main memory may be, 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 referred to as 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 for reading and writing data from and to the recording medium. The recording medium is not particularly limited and may be, for example, an internal or external type, such as a hard disk (HD), CD-ROM, CD-R, CD-RW, MO, DVD, flash memory, or memory card. The storage device 104 may be, for example, a hard disk drive (HDD) or a solid state drive (SSD) in which the recording medium and drive are integrated. When the 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 on 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, affiliated organization, address, contact information, hobbies, preferences, etc.), biometric information, etc.), token issuance request information, blended product identification information, blended token, blended target identification information, blended target token, 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 stored in a distributed manner across multiple terminals using blockchain technology or the like.

[0022] The device 10 further includes, for example, an input device 105 and an output device 106. Examples of the input device 105 include pointing devices such as a touch panel, track pad, and mouse; a keyboard; imaging means such as a camera and scanner; card readers such as an IC card reader and a magnetic card reader; and audio input means such as a microphone. Examples of the output device 106 include display devices such as an LED display and a liquid crystal display; audio output devices such as a speaker; a printer; and 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 Figure 3. The blended token trading support method of the present disclosure is implemented as follows, for example, using the device 10 of Figure 1 or Figure 2. Note that the blended token trading support method of the present disclosure is not limited to use of the device 10 of Figure 1 or Figure 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 target material (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 that enables it to be distinguished from other NFTs, and therefore can have unique value that is distinguishable 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 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, for example, store the blended token in the memory 102 or the storage device 104. In this case, the token issuing unit 11 may, for example, store blended product identification information of the blended product corresponding to the blended token, linked to the blended token. Note that in FIG. 1 , each node 31 of the blockchain network 30 is depicted as a different terminal from the blended product administrator terminal 40 and the trader terminal 50, but some or all of the blended product administrator terminal 40 and the trader terminal 50 may function as nodes 31 of the blockchain network 30.

[0025] The token issuing unit 11 may issue the blended token based on, for example, token issuance request information. The token issuance request information is, for example, information from a person desiring issuance of a blended token (also referred to as an issue requester) requesting the issuance of a blended token from the device 10, and includes blended product identification information of alcoholic beverage products. The issue requester may be, for example, a blended product manager (e.g., a manufacturer, seller, distributor, etc. of the blended product) or the owner of a blended token, which will 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 can identify (specify) the blended product, and examples of the information include a serial number (lot number), the name of the blended product, etc. In this case, the token issuing unit 11 may obtain the token issuance request information from, for example, the terminal 40 of the blended product manager (issue requester) in FIG. 1, or may obtain the token issuance request information by input from the manager of the 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] Furthermore, 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 section 12, which will be described later. 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 fluctuate, a trading period, information on the blended product identified by the blended product identification information linked to the blended token, etc. If the blended product is a blended alcoholic beverage obtained by blending (mixing) alcoholic beverage products, specific examples of the information on the blended product include, 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 blending target product is, for example, information on the alcoholic beverage products used in the blending, and includes information such as the product name, alcohol content, information on the production location (e.g., place of origin, manufacturer (brewery), etc.), information on the manufacturing method (e.g., ingredients, rice polishing ratio, variety, etc.), information on taste (e.g., sweetness, sourness, sake meter value, etc.), volume, production date, product appearance (e.g., container photo), product description, etc. The provider identification information is, for example, information for identifying the provider of the blending product, and may include information such as the store name, product information (product type, price), delivery method, name, nickname, address, telephone number, email address, ID, identification number, and identification information of the device 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 token is issued for the blended product instead of the blended product.

[0028] Furthermore, 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 examples thereof include a program for realizing a mechanism in which a portion of the distribution price of the blended token is added as a fee to the administrator of the device 10 or the administrator 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 on the market (S2, market step). Furthermore, for example, if the blended token has been issued, the market unit 12 may publish the blended token on the market. Specifically, for example, the market unit 12 can publish the blended token and the blended token on the market by transmitting the blended token and the blended token to a general blockchain marketplace via a communication network. Furthermore, for example, the market unit 12 may further transmit trading information to the blockchain marketplace. The trading information is, for example, information necessary for trading NFTs on 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 device 10. As a specific example, for example, an administrator of the blended product who uses the device 10 may register an account to be used when using the device 10, and some or all of the trading information may be associated with the account and stored. The market unit 12 may itself have the function of the blockchain marketplace. In this case, the market unit 12 of the device 10 may be, for example, a market (store) server, a device independent of the other units of the device 10. In this case, the market (store) server may be capable of communicating with devices having the other units of the device 10. Note that when the market unit 12 has the marketplace function, payment may be made by the device 10, or may be made separately outside the device 10. In the former case, the device 10 may include a payment unit, for example. In this case, the payment unit acquires trading price information for the blended token and the blended token based on the transaction information described below, transmits the trading price information to a payment server outside the device, and acquires the settlement result from the payment server, thereby executing payment processing. Note that the payment processing is not particularly limited, and various methods used in known payment devices may be used, for example.

[0030] The market unit 12 may have a market function for reselling the blended token and the blended token. In this case, the market unit 12 can, for example, obtain listing information for the blended token and the blended token from their owners 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, phone number, email address, ID, identification number, identification information of the terminal owned by the administrator of the blended product or the administrator of this device 10 (e.g., serial number, IMEI (International Mobile Equipment Identity), IP address, MAC address, etc.)), price information, and selection instruction information (described later).

[0031] Next, the transaction information acquisition unit 13 acquires transaction information on the market for the blended token and the blended tokens (S3, transaction information acquisition step). The transaction information is, for example, information on transactions between the blended token and the blended token in the blockchain marketplace, and includes, for example, the transactors (e.g., seller, buyer), transaction date and time, transaction location, the blended token and the blended token that were the subject of the transaction, and the transaction price. The transaction information may also include, for example, selection instruction information, which will be described later in embodiment 3. The transaction information acquisition unit 13 can acquire the transaction information from, for example, a server device that builds the blockchain marketplace. Furthermore, if the market unit 12 of the device 10 has a function as a blockchain marketplace, the transaction information may be acquired from the market unit 12. If the market unit 12 has a market function for resale, the transaction information acquisition unit 13 may acquire, for example, transaction information on the market for the blended token and the blended token 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 purchaser of the blended token and the blended token as the owner of the blended token and the blended token in the blockchain network 30 as the owner information. Furthermore, if a blended token and the blended token that already have an owner are put up for sale on the market unit 12 and purchased by another trader, the token management unit 14 registers the purchaser as the new owner of the traded blended token and the blended token in the blockchain network 30. Registration of information in the blockchain network 30 can be similar to, for example, step S1. This allows the owners of the blended token and the blended token to be registered in the blockchain network 30, making it possible to clarify the owner of a product identified by product identification information linked to the blended token and the blended token.

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

[0034] The blended token trading support device of the present disclosure can issue a blended token that is linked 1:1 to a blended product identified by blended product identification information, and can record transactions of the blended token on a blockchain network. Furthermore, the blended token issued by the blended token trading support device of the present disclosure is, for example, linked 1:1 to the blended product identified by the blended product identification information. Therefore, the blended token trading support device of the present disclosure enables indirect trading of the blended product by trading the blended token. Furthermore, the blended token has a 1:1 relationship with the blended product identification information, and the trading history and information regarding the blended product linked to the blended token can also be recorded on the blockchain network. This makes it possible to guarantee the authenticity and value of the blended product being traded.

[0035] Furthermore, the blended token transaction support device of the present disclosure can also record blend record information linked to the blended token on the blockchain, thereby ensuring the authenticity of the blended product.

[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 first embodiment, 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 the first embodiment, and the description thereof can be cited. 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, wherein the blending designation information acquisition unit acquires blending designation information, the blending designation information being information for specifying at least two types of blended tokens to produce a blended product, the blending instruction unit outputs blending instruction information for producing a blended product by blending the blended materials 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 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.

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

[0039] Next, an example of the blended token trading support method of the present disclosure will be described based on the flowchart in Figure 5. The blended token trading support method of the present disclosure is implemented as follows, for example, using device 10A of Figure 4. Note that the blended token trading support method of the present disclosure is not limited to use of device 10A of Figure 4. Furthermore, 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 producing 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) specified by the user, the mixing ratio of the specified blending target products, mixing conditions, mixing amount, and unit filling amount of the blended blended product. The mixing conditions include, for example, temperature, mixing method, equipment (container) used for mixing, mixing time, and information about the mixer. The unit filling amount is, for example, the amount per container when the blended blended product is filled into a container. The unit filling amount may be, for example, an amount selected from at least one specified amount specified by the device 10A, or an amount arbitrarily set by the user. The device 10A may, for example, propose an appropriate unit filling amount based on 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, for example, at least one of the trader and owner of the blended token. The blending designation information acquisition unit 11 may acquire, for example, the blending designation information input by a user during the transaction processing of the blended token in the marketplace, or may acquire blending designation information separately input (purchased) 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) when trading the blended token.In this case, the market unit 12 may, for example, display a button that allows the user to select whether or not to make the blended token a blend target when publishing the blended token on the market. The blending designation information acquisition unit 11 may, for example, associate the acquired blending designation information with the blended token linked to the designated blended product and store it in the memory 102 or the storage device 104. Furthermore, the token management unit 14 may, for example, associate the acquired blending designation information with 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 specification information (S12, blending instruction step). The blending instruction information is information for producing a blended product by blending multiple blending objects linked to blending object tokens included in the blending specification information in accordance with the blending conditions, and is also referred to as 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 device 10A, a keeper of the blending objects, or a manufacturer of the blended object.

[0042] Specifically, the blending instruction unit 16, for example, references the blending token specified by the blending specification information and identifies the current manager of the blending product linked to the specified blending token. Then, the blending instruction unit 16, for example, outputs the blending instruction information to the manager of the blending product. The manager of the blending product (the provider, the manager, the custodian) to whom the blending instruction information is output blends the blending products in accordance with the blending conditions included in the blending instruction information to produce a blended product. For example, if there are multiple current managers of the blending product identified based on the blending specification information, the blending instruction unit 16 outputs the blending instruction information to each manager. In this case, the blending instruction information may, for example, be information instructing a manufacturer of the blended product to transport the quantity of the blending product specified in the blending specification information. Then, the blending instruction unit 16 also 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 product blends the blending products in accordance with the blending instruction information to produce a blended product.

[0043] The token issuing unit 11, for example, acquires blended product identification information linked to blended products blended based on the blending instruction information, and issues a blended token on the blockchain for each blend 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 blend identification information of a 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 a blended product blended based on the blending instruction information. The blended product identification information may be identification information issued by a blended product manager or a blended product manufacturer, or may be identification information issued by the token issuing unit 11 based on information such as the quantity of blended products. Then, the token issuing unit 11 can generate a blended token linked to the blend identification information for each blended product. The market unit 12, for example, publishes the blended tokens on a market. The market may be the same as or different from the market in step S2 of the first embodiment.

[0044] Furthermore, the token issuing unit 11 may, for example, link the blend token and / or the blend designation information and / or the blend instruction information to the blockchain as blend record information for the blended product. This allows, for example, the blending history of the blend token to be recorded in the blockchain, thereby ensuring the authenticity of the blended product.

[0045] The token management unit 14 updates the information on the blockchain of the blended tokens linked to the blended products 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 a blended product, the quantity of the blended product linked to the blended token decreases or disappears. Therefore, the token management unit 14 references 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. Furthermore, when the entire amount of the blended product linked to the blended token has been 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, wherein the blending designation information acquisition unit acquires blending designation information, which is information for specifying at least two types of blended tokens to produce a blended product, the blending instruction unit outputs blending instruction information for producing a blended product by blending the blended materials based on the blending designation information, the token issuance 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 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.

[0047] By outputting blended product manufacturing instructions to a blended product manufacturer via the blended token trading support device of the present disclosure, an owner or trader of a blended token can manufacture a blended product without possessing the actual blended product. Furthermore, the blended token trading support device of the present disclosure can record at least one of the blending designation information and the blending instruction information in a blockchain linked to the blended token as blending record information for a blended product manufactured at the user's instruction. Furthermore, information about the user who input the blending designation information can be recorded in a blockchain linked to the blended blend token as a blending record for the blended product. Therefore, the blended token trading support device of the present disclosure can record the creator of a blended product's blend recipe in a blockchain. This can be expected to have the effect of, for example, ensuring that the creator of a blended recipe is truly the creator of the blended recipe.

[0048] The value of blended products may increase significantly when blended. For example, when whiskey or aged sake (e.g., so-called aged sake) is blended to form a blended whiskey or blended sake (a blended product), the taste and aroma are adjusted, and the value may be higher than that of the original whiskey or aged sake (the blended product). However, it is difficult to compare the value of the blended product with that of the blended product, making it difficult to evaluate the value of the blended product compared to the original blended products. 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 on the market. Therefore, the blended token trading support device of the present disclosure can visualize the market value of the blended product and the market value of the blended products from which it is blended. Furthermore, the blended token trading support device of the present disclosure can visualize the new value created by blending the blended products by calculating the difference between the market value of the blended product and the market value of the blended products from which it is blended.

[0049] Furthermore, conventionally, blended product manufacturers (blenders) have had difficulty objectively demonstrating the value they have created by producing blended products. Instead of the value they themselves can create, they are evaluated only by vague criteria such as whether they are famous or unknown. The blended token trading support device disclosed herein can, for example, record blending record information linked to a blended token. Because the blending record information includes blending designation information, by referencing the blending record information, it is possible to track the blended objects that make up the blended product linked to the blended token, the market value of the blended objects (the trading price of the blended object tokens in the market), and the user who issued the blending instruction for the blended product. Therefore, the blended token trading support device disclosed herein allows, for example, a user to record and prove the blend value of the blended product they created (the difference between the market value of the blended product and the market value of the blended object products from which it was blended). Therefore, the blended token trading support device disclosed herein allows, for example, a user, i.e., a blended product manufacturer (blender), to objectively demonstrate to others the blended value of the blended product they created.

[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 second embodiment, 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 the second embodiment, and the description thereof can be cited. 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, wherein 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] Figure 6 is a block diagram showing an example configuration of a blended token trade support apparatus 10B of the present disclosure. As shown in Figure 6, the blended token trade 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 trade support apparatus 10A of embodiment 2. The hardware configuration of the blended token trade support apparatus 10B is the same as that of the blended token trade support apparatus 10 of Figure 2, except that the central processing unit 101 has the configuration of the blended token trade support apparatus 10B of Figure 6 instead of the configuration of the blended token trade support apparatus 10 of Figure 1.

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

[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, for example, the selection instruction information input by a user during the transaction processing of the blended token and the blended target token in the marketplace, or may acquire selection instruction information separately input (purchased) by a user who 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. Furthermore, the token management unit 14 may, for example, 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 can be additionally selected by a user (trader) when trading blended tokens and blended tokens in the marketplace. Specifically, the selection instruction information may include, 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 regarding the storage state may be, for example, information specifying in detail storage conditions (management conditions) such as temperature, humidity, brightness of the storage location, storage containers, and storage period, or information specifying a category of storage state (management state) such as frozen, quick-frozen (also called flash-frozen), refrigerated, room temperature, and aging. In the latter case, it is preferable that the device 10B stores in its memory, for example, a combination of the storage state category and corresponding detailed storage condition information for each type of the blended product and the products to be blended.

[0057] Furthermore, the selection instruction information may include, for example, information regarding the delivery of the blended product and blending target products (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 blending target products may be acquired simultaneously with information specifying the storage conditions of the blended product and blending target products, or may be acquired separately. In the latter case, the selection instruction information including information regarding delivery is also referred to as, for example, delivery request information. The owner of the blending token and blending target token may be able to request delivery of the blended product and blending target products linked to the blending token and blending target token that he or she owns at any time, or may be able to request delivery only within the preset expiration date of the blending token (blending target token).

[0058] Next, the instruction information output unit 17 generates instruction information based on the selection 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 storage conditions for the blended product and the blending target product, the instruction information output unit 17 can, for example, generate product management instruction information based on the selection instruction information as the instruction information. Specifically, when the selection instruction information includes detailed information regarding 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. Furthermore, 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 memory unit, reference the storage conditions associated with the storage condition category corresponding to the blended product and the blending target product purchased by the purchaser, and generate and output the information on the storage conditions as the instruction information. The output destination of the instruction information may be, for example, the provider of the alcoholic beverage product, the administrator of the device 10B, a delivery company, or a storehouse of the alcoholic beverage product. The delivery company and storehouse are preferably, for example, persons designated by the administrator.

[0060] The manager of the blended product and blending target products (e.g., the provider, the custodian, etc.) who has received the instruction information can change the storage status of the blended product and blending target products based on the instruction information. The change in storage status may be performed, for example, by the manager himself or herself, or by another party (e.g., a delivery company, distributor, or storage company) who receives instructions from the manager. The manager can then transmit information regarding the storage status of the blended product and blending target products as management information to the device 10 using, for example, his or her 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, for example, be output directly to the terminal of the provider, trader, purchaser, etc., or may be output so that it can be viewed on the blockchain marketplace. This allows purchasers of the blended token or blending target token to check the management information of the blended product and blending target products via the device 10B. However, this is not limited to this, and for example, the device 10B may acquire storage information of the corresponding blended products and blended products as the management information 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 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 delivery of the blended product and the blending target products based on 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.). The instruction information output unit 17 can then output the delivery instructions to terminals of the provider, manager, delivery company, warehouse management company, distributor, etc.

[0062] The manager of the blended product and the blended products who received the instruction information may, for example, arrange for the delivery of the blended product and the blended products based on the delivery instruction. The delivery arrangements may be made by the manager himself or by another party (e.g., a delivery company, distributor, or storage company) who receives instructions from the manager. The manager may then transmit information regarding the delivery status of the blended product and the blended products as management information to the device 10 using, for example, his or her own terminal (terminal 40). The instruction information output unit 17 of the device 10 may, for example, acquire the transmitted management information and output the management information by linking it to the corresponding blended token. The output may, for example, be output directly to the terminal of the provider, trader, purchaser, or the like, or may be output so that it can be viewed on the blockchain marketplace. This allows purchasers of the blended token or the blended token to check the delivery status of the blended product and the blended products via the device 10B.

[0063] As a specific example, the following will explain a case where the blended product and the product to be blended are sake, and a sake brewery, which is an alcoholic beverage provider, uses this device 10B to generate an NFT for a sake product (sake NFT) and support trading of alcoholic beverage 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 the 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, using their 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 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 on the blockchain that are associated one-to-one with the product identification information. The device 10 then publishes the registered sake NFTs on a blockchain marketplace via the market unit 12. FIG. 9 shows an example screen of an NFT market published by the device 10; however, 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, published sake NFTs can be searched using the marketplace's functions, and are displayed in a list in response to a user's search operation. The search method is not particularly limited, and examples include keyword search, price search, and tag search. The marketplace may also have a tag search function, a sorting function, a filtering function, and the like. The marketplace's functions may also include, for example, a function for aggregating and displaying the number of views and likes for each sake NFT. The marketplace may also have a function for displaying rankings of sake NFTs based on the trading history of sake NFTs (volume, price, price fluctuation range, number of views, number of likes, etc.). In this case, the rankings 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 wishing to purchase sake via this device 10 can access the blockchain marketplace published by this device 10 using their own terminal 50 and view the published sake NFTs as shown in Figure 9. If the trader wishes to purchase the viewed sake NFT, they will carry out a sake NFT purchase process 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, if the trader selects, as selection instruction information, that the sake be flash-frozen for 10 years as the storage condition for the sake when purchasing the sake NFT, the device 10 acquires the selection instruction information. The 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 device 10 or the sake product producer (brewery). Based on the instruction information, the administrator or brewery then ships the sake product to a flash-freezing facility, flash-freezes the product at the flash-freezing facility, and stores it in a cold storage warehouse. The owner or manager of the flash-freezing facility may or may not be the same person as the administrator or brewery of the device 10, but it is preferable that the facility be managed by the administrator of the device 10. The device 10 can also acquire management information about the storage condition of the sake product from the cold storage warehouse and output it for viewing 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 a trader trades sake NFTs that he or she owns through 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 unit 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 through the device 10.

[0069] When the trader needs to have a sake product linked to a sake NFT he or she owns delivered, 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. Upon receiving the selection instruction information regarding the delivery, the device 10 generates a delivery instruction based on the selection instruction information and outputs the delivery instruction to a terminal of the warehouse manager who manages the cold storage warehouse. The warehouse manager then processes the shipment of the alcoholic beverage product corresponding to the sake NFT based on the delivery instruction. This allows the trader to have the sake product linked to the sake NFT he or she owns delivered.

[0070] When the blended product is an alcoholic beverage, it is generally known that the value of the alcoholic beverage varies greatly depending on its storage conditions. On the other hand, even for the same alcoholic beverage, how the value of the alcoholic beverage is assessed based on its storage conditions varies greatly depending on the preferences and values ​​of the alcoholic beverage consumer. Specifically, for example, even for the same alcoholic beverage produced at the same brewery, one consumer may value fresh alcohol immediately after production more highly, while another consumer may value alcohol that has been aged for many years more highly. However, the ability to select the storage and management conditions of alcoholic beverages (e.g., whether to flash-freeze fresh alcohol immediately after production or to store it for aging) is typically limited to the alcoholic beverage manufacturer, and alcoholic beverage traders have no control over the storage and management conditions of alcoholic beverages. The present disclosure enables blended token traders to specify the storage condition category as selection instruction information, even in such cases. Therefore, according to the present disclosure, traders who purchase blend tokens will be able to choose, for example, to flash-freeze some of the alcoholic beverages to ensure value for consumers who prefer fresh alcoholic beverages, and to age some of the alcoholic beverages to ensure value for consumers who prefer aged alcoholic beverages, thereby 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 tends to increase in trading price over time, increasing its trading price with secondary distribution and its value as an asset. In contrast, sake, beer, plum wine, shochu, and other alcoholic beverages have less stable asset value than wine, and since there is no secondary distribution market, their trading prices are less likely to rise and their profitability is low. Therefore, the blended token trading support device of the present disclosure issues blended tokens for these alcoholic beverage products, and after the blended product manager sells them, other traders resell them via the blended tokens, which is expected to increase the final selling price. In this case, if the blended token has an additional function, such as a function to add a portion of the distribution price as a fee to the manager of the device 10B or the provider of the alcoholic beverage when the blended token is recirculated, profitability can be further improved. Furthermore, since the market price of sake is often lower than that of wine and other alcoholic beverages relative to its product quality, the blended token trading support device of the present disclosure is suitable for supporting transactions of sake products via blended 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 linked to a blended product obtained by mixing at least one blending target material; 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 can be incorporated by reference to the descriptions of the blended token transaction support device and blended token transaction support method of the present disclosure. For example, the "procedure" in each of the steps can be read as "processing." The program of the present disclosure may be recorded on, for example, 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 (e.g., solid state drive (SSD), USB flash memory, SD / SDHC card, etc.), optical disk (e.g., CD-R / CD-RW, DVD-R / DVD-RW, BD-R / BD-RE, etc.), magneto-optical disk (MO), floppy disk (FD), etc. The program of the present disclosure (e.g., also referred to as a programming product or program product) may be distributed from an external computer, for example. The "distribution" may be, for example, distribution via a communication network or distribution via a device connected via 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.
