DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0017] The trading system, trading method, and management server according to the embodiment of the present invention 2 It provides a marketplace for trading non-fungible tokens (hereinafter abbreviated as NFT) of digital twins of facilities for a decarbonized society, such as collection facilities and mega solar facilities. Naturally, the facilities referred to here conceptually include factories, smart cities, etc.

[0018] By purchasing NFTs, ordinary users become the digital owners of equipment and receive daily CO2 for each piece of equipment. 2 You can check the amount of CO 2 You can acquire value according to the amount of collected CO2, and utilize the accumulated value. 2 The amount of collected carbon dioxide will be visualized and can be checked daily, so general users can easily check the amount of CO 2 This will allow people to feel closer to the idea of ​​"reduction."

[0019] Therefore, it will act as a bridge to decarbonization hard technologies that are not familiar to general users, and will also 2 This new method of shortening the distance between collection facilities and consumers will encourage behavioral change among people around the world and help accelerate global efforts toward the ambitious goal of achieving a carbon-free society by 2050.

[0020] To achieve the above-mentioned effects, the trading system, trading method, and management server according to the embodiment of the present invention operate and manage an NFT marketplace. This marketplace allows not only the buying and selling of NFTs, but also various other transactions such as resale and auction of NFTs. In the course of transactions in this marketplace, the value of the NFT will increase, and the accumulated value will indicate the status and asset value of the NFT.

[0021] In addition, according to the trading system and the like according to the embodiment of the present invention, a virtual world is constructed in which the earth is divided into predetermined units such as latitude and longitude, each divided square is defined as a cell, and the results of efforts to realize a decarbonized society (e.g., CO 2 By visualizing and sharing the results, it is possible to increase the motivation of companies with roots in the region and users who have an emotional attachment to the region, and to further accelerate the efforts.

[0022] In addition to the above, various platforms utilizing blockchain and the like are being realized every day today, and the power consumption associated with the operation of these platforms is enormous. In order to improve the environment, it is desirable to take measures and considerations regarding such power consumption. According to an embodiment of the present invention, by allocating a portion of the investment in NFTs to donations, it is possible to provide a technology that takes into consideration the impact on the environment due to the power consumption, etc., associated with the operation of the platform.

[0023] FIG. 1 shows the configuration of a trading system according to an embodiment of the present invention.

[0024] As shown in the figure, a trading system according to an embodiment of the present invention realizes trading of NFTs related to digital twins of facilities toward a carbon-free society. The trading system includes a management server 1, a user terminal 2, a corporate server 3, a relay server 4, and a blockchain 5. The management server 1 is connected to the user terminal 2, the corporate server 3, and the relay server 4 via a network 6 such as the Internet. As the user terminal 2, various devices such as a smartphone, a tablet terminal, a notebook personal computer, or a desktop personal computer can be used.

[0025] Here, "user" refers to general consumers who wish to make transactions such as purchasing NFTs. In FIG. 1, only one user terminal 2 is illustrated, but in reality, there are multiple user terminals 2. On the other hand, "companies" are owners of equipment aimed at a carbon-free society, and are entities that wish to trade NFTs related to their equipment through this service. In FIG. 1, only one corporate server 3 is illustrated, but in reality, there are multiple corporate servers 3. Of course, these corporate servers 3 include not only owners of the equipment, but also companies and local governments that conduct corporate PR and campaigns for cells, which will be described later.

[0026] Blockchain 5 is a technology that combines encryption technology with multiple computers that make up a distributed network, and then synchronizes and records NFTs. In this embodiment, for example, a distributed application platform equipped with a smart contract function can be used as the blockchain 5. However, it is not limited to this, and can be linked to a wide variety of platforms.

[0027] In this configuration, when a company that owns equipment for a decarbonized society desires to trade using this service, the company applies for the service. When applying, the company server 3 transmits data related to the equipment to the management server 1. When the management server 1 accepts the application, it generates a digital twin based on the data related to the equipment. Here, the "digital twin" is not, for example, a simple visual copy of equipment for a decarbonized society operated by a company, but data that allows the operation information of the equipment to be synchronized between the real world and the virtual world. In this embodiment, a digital twin is generated based on image data and specification data of equipment for a decarbonized society transmitted from a company, which realizes synchronization with the operation data of the equipment in the real world.

[0028] Next, the management server 1 issues an NFT for the digital twin on the blockchain 5 and performs distributed ledger management. After this, the NFT will be available to the general public on the marketplace operated by the management server 1, and various transactions, such as purchases, will be carried out in response to requests.

[0029] When a request to purchase an NFT is made by the user terminal 2, the management server 1 updates the registration information of the NFT, executes a prescribed payment process, and then sends a notification of the completion of the transaction to the user terminal 2. Here, updating the registration information is an internal process that links the user information of the user as the purchaser to the NFT registration information managed within the management server 1, and the owner of the NFT managed in the blockchain 5 remains the operator. When the management server 1 receives a request from the purchaser to transfer ownership of the NFT, it executes a transaction on the smart contract to transfer ownership of the NFT.

[0030] At companies participating in this service, the company servers 3 periodically transmit operation information of facilities and other equipment aimed at a decarbonized society that have already been converted into NFTs to the relay server 4. The relay server 4 compiles and stores the operation information sent individually from multiple company servers 3. The management server 1 reads out the operation information stored by the relay server 4 at a predetermined timing, calculates the value to be returned to users who are NFT purchasers based on the operation information, and updates the value information associated with the user information.

[0031] Users can check the accumulated value at any time on their My Page on the marketplace, and can utilize the value in electronic payments, etc. Here, the value refers to at least one of points, miles, virtual currency, financial asset tokens, and in-service currency. For example, points are something that are usually used with 1 point being worth 1 yen, and miles have asset value such as 100 miles being exchanged for a cup of coffee, or 100 miles being exchanged for 200 points from a certain business.

[0032] In addition to the above, the trading system according to this embodiment creates a mesh-like virtual world in which the Earth is divided into specific latitude and longitude units, and defines each square as a cell. The amount of CO2 reduction in the real world by facilities linked to NFTs is calculated. 2 Of the reduction amount, the CO on the day when the digital owner of the NFT sent a support notification (hereinafter referred to as an “appeal”) 2 Only the reduction amount in the virtual world 2 Therefore, digital owners of NFTs can earn CO2 reductions in the virtual world. 2By allocating the reduction amount to the desired cell and achieving carbon neutrality for each cell, users can feel that they are ultimately contributing to achieving carbon neutrality worldwide. In addition, when carbon neutrality is achieved in each cell, data such as the cell's geographical information and the date and time of achievement is input to generate AI art (reward image) that indicates the cell (area) and give it to the digital owner. Note that while the reward image will be based on AI art, it may also be collaborative art with artists or characters associated with the cell, or corporate tie-up art.

[0033] The trading system is 2 Reduction status, index image (including reward image), number of cheers by digital owners of NFTs, donation amount, actual equipment operation volume, CO 2 Since the reduction power is managed, users can check the CO 2 It will be possible to confirm the results of efforts to reduce emissions. It will also be possible for local businesses and local governments with roots in the region to conduct PR and campaigns for each cell.

[0034] Furthermore, the trading system issues and grants a digital certificate (index image) indicating the environmental contribution level to the digital owner who sent the cheer. Therefore, by checking the index image of each cell, users can check the environmental contribution level of the cell they are supporting, i.e. the local CO2 emissions. 2 The degree of reduction achieved can be checked as needed using a visualized indicator image, which increases the motivation of users to support local communities, promoting support activities and ultimately reducing CO emissions in each region. 2 This will enable us to accelerate our efforts to reduce emissions.

[0035] In addition to the above, the trading system awards cheer points to users who have invested in NFTs, etc., and when these cheer points are used to cheer on a cell (including NFTs related to the facilities where the cell is located), this leads to an improvement in the cell's reputation, and a portion of the cheer points spent on the cheer is allocated to a donation. Users can select the desired donation destination from multiple destinations. The donation rate can be preset, such as a certain percentage of the cheer points cheered on, and can also be increased or decreased in accordance with campaigns, etc.

[0036] In this way, the trading system according to the embodiment of the present invention allows a portion of the investment in NFTs to be donated, which takes into consideration the impact on the environment caused by the massive electricity consumption associated with platform operation. This provides an environment in which both users and platform operators can further contribute to achieving carbon neutrality through CO2 reduction, and promotes such activities worldwide.

[0037] 2(a), 2(b) and 2(c) show the configuration of the management server of the trading system and will be described.

[0038] As shown in the figure, the management server has a control unit 11, a communication unit 12, and a storage unit 13. The control unit 11, the communication unit 12, and the storage unit 13 are communicatively connected via a bus line. In addition, the management server may have an input unit such as a keyboard or a mouse, and a display unit such as a liquid crystal display for performing various displays. The communication unit 12 is realized by, for example, a network interface card (NIC) or the like, and is a communication interface that is connected to a network 6 such as the Internet by wire or wirelessly and communicates with the user terminal 2, the enterprise server 3, the relay server 4, etc.

[0039] The storage unit 13 is realized by, for example, a semiconductor memory element such as a random access memory (RAM) or a flash memory, a hard disk drive (HDD), a solid state drive (SSD), or the like, and stores a program executed by the control unit 11. Here, the storage unit 13 has, for example, a user information storage unit 14, a company information storage unit 15, a digital twin storage unit 16, an NFT storage unit 17, a management information storage unit 18, and a transaction information storage unit 19.

[0040] That is, in more detail, the user information storage unit 14 is a database that stores a user's name, email address, payment information, transaction history information, value history information, cheer information (including remaining cheer points, annually earned cheer points, and lifetime earned cheer points), etc., linked to a user ID. The company information storage unit 15 is a database that stores the company's name, facility location (latitude and longitude of location, etc.), manager's email address, payment information, transaction history information (including product ID), PR information, campaign information, etc. Furthermore, the digital twin storage unit 16 is a database that stores digital twin information, etc. related to the product, linked to a product ID.

[0041] The NFT memory unit 17 is a database that stores the product ID, provider (company ID), purchaser (user ID), owner, transaction terms, etc., which are linked to the NFT ID to identify the digital twin information that is the subject of the NFT.

[0042] The management information storage unit 18 is a database that stores CO2 reduction status, index images, cheer information (e.g., cheer number, remaining cheer points, cheer points earned annually, cheer points earned lifetimely, etc.), donation information (e.g., donation amount, donation destination, donation date, etc.), actual equipment operation volume, CO2 reduction power, company PR information (including company ID), campaign information, etc. The transaction information storage unit 19 is a database that stores NFT IDs that identify transaction targets by linking them to transaction IDs, transaction history information, etc. Note that these are merely examples, and the present invention is not limited to these, of course.

[0043] The control unit 11 is realized by a CPU (Central Processing Unit), MPU (Micro Processing Unit), etc., and functions as, for example, a transmission / reception control unit 11a, a digital twin management unit 11b, an NFT management unit 11c, a marketplace management unit 11d, a transaction processing unit 11e, an operation management unit 11f, a value calculation unit 11g, and a settlement unit 11h by executing a program stored in the storage unit 13. The control unit 11 is composed of integrated circuits such as an ASIC (Application Specific Integrated Circuit) and an FPGA (Field Programmable Array).

[0044] In such a configuration, the transmission / reception control unit 11a controls the transmission and reception of data with the user terminal 2, the corporate server 3, etc. via the communication unit 12. For example, the transmission / reception control unit 11a functions as a receiving unit that accepts requests to purchase NFTs from the user terminal 2 and a service application request from the corporate server 3 via the communication unit 12, and as a transmitting unit that transmits various notifications to the user terminal 2 and the corporate server 3, and controls various transmissions and receptions.

[0045] The digital twin management unit 11b generates a digital twin based on image data and specification data related to equipment for a decarbonized society transmitted from the corporate server 3, and registers and manages the digital twin in the digital twin memory unit 16.

[0046] More specifically, as shown in FIG. 2(b), the NFT management unit 11c has an NFT issuing unit 11c-1, an NFT registration unit 11c-2, and a transaction execution unit 11c-3. The NFT issuing unit 11c-1 reads a digital twin from the digital twin storage unit 16 and issues an NFT based on the digital twin on the blockchain 5. The NFT registration unit 11c-2 links the issued NFT with an NFT ID, registers it in the NFT storage unit 17, and manages it. As a result, the NFT is shared by the management server 1 and multiple nodes of the blockchain 5, and is managed in a distributed ledger in an unalterable state. For example, when a request for the transfer of ownership of an NFT is made by a user who is a purchaser, the transaction execution unit 12c-3 works on a smart contract of the blockchain 5 to execute a transaction such as the transfer of ownership.

[0047] The marketplace management unit 11d provides a marketplace related to the buying and selling of NFTs and manages its operation. Specifically, the marketplace presents purchasable NFTs to users along with transaction information such as their value, and manages the transactions. The user terminal 2 utilizes the marketplace as a web service through a web browser function, or by installing an application program for conducting transactions, as will be described in detail later.

[0048] The transaction processing unit 11e processes transactions based on requests from the company server 3 to apply for the service and requests from the user terminal 2 to purchase NFTs, updates the registration information in the storage unit 13, and transmits notifications regarding transaction completion and the like to each party. For example, when the transaction processing unit 11e receives a request from the company server 3 to apply for the service, it updates the registration information (transaction history information, etc.) in the company information storage unit 15 and the registration information in the transaction information storage unit 19. On the other hand, when the transaction processing unit 11e receives a request from the user terminal 2 to purchase NFTs, it appropriately updates the registration information (transaction history information, etc.) in the user information storage unit 14 and the registration information in the transaction information storage unit 19. The transaction processing unit 11e is responsible for processing various transactions, such as purchase, sale, resale, and auction of NFTs on the marketplace.

[0049] As shown in FIG. 2(c), the management unit 11f includes a cell management unit 11f-1, an equipment NFT management unit 11f-2, and an equipment management unit 11f-3. The cell management unit 11f-1 further includes a status management unit 11f-1a and an index image management unit 11f-1b. The equipment NFT management unit 11f-2 further includes a cheer information management unit 11f-2a and a donation information management unit 11f-2b. The equipment management unit 11f-3 further includes an operation amount management unit 11f-3a and a CO2 reduction power management unit 11f-3b.

[0050] In the cell management unit 11f-1, the status management unit 11f-2 calculates the CO 2 Based on the amount of CO reduction 2 The status related to the reduction activity is identified, and the registered information in the management information storage unit 18 is updated and managed. In this example, the status is “initial state (CO 2 """CO 2 The indicator image management unit 11f-1b updates and manages the registration information in the management information storage unit 18 for indicator images such as a digital certificate generated by the generation unit 11i each time the cell status is updated and a reward image generated when carbon neutrality is achieved.

[0051] In the facility NFT management unit 11f-2, the cheer number management unit 11f-4 manages cheer information such as the number of cheers, which are cheer notifications sent from NFT owners, for each cell, and at a predetermined timing updates the registered information in the management information storage unit 18. The donation amount management unit 11f-5 updates the registered information in the management information storage unit 18 based on donation information such as the donation amount associated with the cheers from the NFT owner calculated by the calculation unit 11g.

[0052] In the equipment management unit 11f-3, the operation amount management unit 11f-1, under the control of the transmission / reception control unit 11a, receives operation information from the relay server 4 via the communication unit 12, and updates and manages the registered information in the management information storage unit 18 based on the operation information. 2 The reduced power management unit 11f-3 updates and manages the registered information in the management information storage unit 18 based on the reduced CO2 power (kg / day) of the cell calculated by the calculation unit 11g from the operation information.

[0053] The calculation unit 11g calculates the CO 2 Reduction, CO 2 The calculation unit 11g calculates the reduction power and calculates the donation amount according to the cheers from the NFT owner. Furthermore, the calculation unit 11g calculates an incentive (cheer points) for the user who sent the cheers, and updates the registration contents of the user information storage unit 14. The calculation rule for the cheer points can be set, for example, as 10% of the sales price of the NFT / 30 days as the base points, and in this example, from the 31st day after purchase, only the base points will be received. However, the calculation rule is an example and is not limited to this. Users can use the cheer points as appropriate, not just by receiving them, but by applying them to the purchase of another NFT or exchanging them for various external points.

[0054] Furthermore, at a predetermined timing, the calculation unit 11g reads out the registration information from the operation information storage unit 18, calculates the new value to be assigned to each NFT under a predetermined calculation formula based on the additional operation amount, etc., and updates the registration information (value history information) of the user who is the purchaser of the NFT by referring to the user information storage unit 14.

[0055] Since such processing is performed periodically, the user can check the current operating volume of the equipment corresponding to his / her NFT and the value returned from it at any time, thereby heightening the awareness that he / she is participating in efforts toward a decarbonized society. Note that "value" refers to any of points, miles, virtual currency, financial asset tokens, and in-service currency. Of course, the value calculation unit 11g may calculate value according to the asset value of the NFT, various campaigns, etc. in addition to the above operating information. More specifically, when calculating the value, it is also possible to change the rate depending on the region, or to change the rate according to the market demand and supply when there is an upper limit on the number of issuances.

[0056] The settlement unit 11h executes electronic settlement when an NFT transaction (e.g., purchase, etc.) is made. For example, when an NFT is purchased by the user terminal 2, the settlement unit 11h refers to the registration information (payment information) in the user information storage unit 14 to execute a withdrawal process for the purchase price, and executes a deposit process for the sales price to the company of the equipment related to the NFT. However, this is not limited to this. Generally, in the case of transactions on a blockchain, settlement is made via a wallet, but in this system, when the owner of the NFT is the operator, it is managed internally with respect to the user, so settlement can be made by general electronic settlement, which is convenient for the user.

[0057] When the cell achieves carbon neutrality, the generation unit 11i uses the geographical information of the cell and the achievement date and time as input to generate AI art (reward image; conceptually included in the index image) depicting the area (land) related to the cell, and generates a digital certificate (conceptually included in the index image) indicating the environmental contribution level according to the achievement level of the CO2 reduction goal. This generated index image is stored in the management information storage unit 18 as a part of the registration information.

[0058] The management server 1 can be composed of one or more servers. That is, for example, it is possible to distribute the processing by allocating the functions related to NFT management and the functions related to marketplace management to multiple servers.

[0059] FIG. 3 shows the configuration of a user terminal of the trading system, and will be described.

[0060] As shown in the figure, the user terminal 2 has a control unit 21, a communication unit 22, an operation unit 23, a display unit 24, and a storage unit 25. The units 21 to 25 are connected to each other via a bus line so as to be able to communicate with each other. The communication unit 22 is realized by, for example, a NIC or the like, and is a communication interface that is connected to a network 6 such as the Internet by wire or wirelessly and communicates with the management server 1 or the like. The operation unit 23 is realized by a mouse, a keyboard, or the like, and receives various operation inputs by a user. The display unit 24 is realized by a liquid crystal display or the like, and performs various displays. The operation unit 23 and the display unit 24 may be integrated into a touch panel. The storage unit 25 is realized by, for example, a semiconductor memory element such as a RAM or a flash memory, a HDD, an SSD, or the like, and stores application programs and the like executed by the control unit 21 consisting of a CPU, an MPU, or the like.

[0061] The control unit 21 has a web browser function and can execute transactions, such as purchasing NFTs, by utilizing the marketplace provided by the management server 1. Alternatively, by installing and executing an application program related to transactions, etc. in the storage unit 25, a transaction function is realized, and it becomes possible to execute various transactions, such as purchasing NFTs, by utilizing the marketplace provided by the management server 1.

[0062] Below, we will explain the processing flow related to the issuance of NFTs by the trading system, with reference to the flowchart of Figure 4.

[0063] When a request to apply for this service is made by the corporate server 3 (S1), the transmission / reception control unit 11a in the management server 1 accepts this application (S2). Then, in the management server 1, the digital twin management unit 11b generates a digital twin based on the image data and specification data related to the equipment for a decarbonized society transmitted from the corporate server 3 at the time of application, and registers the digital twin in the digital twin storage unit 16 (S3).

[0064] Next, in the management server 1, the NFT management unit 11c issues an NFT. More specifically, the NFT issuing unit 11c-1 reads the digital twin from the digital twin storage unit 16 and issues an NFT based on the digital twin on the blockchain 5. The NFT registration unit 11c-2 links the issued NFT with an NFT ID, registers it in the NFT storage unit 17, and manages it (S4, S5). As a result, the NFT is shared by the management server 1 and multiple nodes of the blockchain 5, and is managed in a distributed ledger in a non-tamperable state (S6).

[0065] Next, the flow of processing related to NFT transactions and the like by the trading system will be described with reference to the flowchart in Fig. 5. Here, the purchase of NFTs will be described as an example.

[0066] On the display screen of the user terminal 2, the user can check the digital twins and purchase conditions of facilities for a decarbonized society that can be purchased. That is, a list of facilities for a decarbonized society for which NFTs can be purchased is displayed on the screen, and the user can switch between the facilities and check them in order by swiping the upper area of ​​the screen. Then, once the facility that the user is considering purchasing has been decided, the user can check the purchase conditions such as the price and the operating history of the facility on the screen.

[0067] Once the desired equipment, etc. is determined and a purchase instruction is given, a purchase application request is made from the user terminal 2 (S11). Then, in the management server 1, the transmission / reception control unit 11a accepts this application (S12). Next, in the management server 1, the transaction processing unit 11e executes processing related to the purchase and updates the registered information in the storage unit 13 (S13). More specifically, the transaction history information, etc. in the user information storage unit 14 is updated, and the registered information in the transaction information storage unit 19 is updated.

[0068] In the management server 1, the settlement unit 11h executes settlement processing associated with the NFT purchase (S14), and the transaction processing unit 11e sends a notification of transaction completion to the user terminal 2 (S15). The user terminal 2 receives the notification via the communication unit 22, and under the control of the control unit 21, displays the notification content on the display unit 24, allowing the user to confirm that the purchase has been completed (S16).

[0069] The above describes the process flow for purchasing NFTs, but the transaction processing unit 11e also executes the process for reselling and auctioning NFTs in a similar manner. For example, in the case of an auction, the user who bids the highest price during a specified bidding period is permitted to purchase the item, and the process is executed in the above-described manner.

[0070] Next, the flow of processing related to browsing of management information related to a cell by the trading system will be described with reference to the flowchart of FIG.

[0071] When a cell for which confirmation of results is desired is selected on the initial screen of the user terminal 2, the control unit 21 transmits a request to view management information to the management server 1 (S21). In the management server 1, the transmission / reception control unit 11a receives this request (S22), and the management unit 11f extracts management information related to the cell from the management information storage unit 18 (S23).

[0072] More specifically, the operation amount management unit 11f-3a extracts the operation capacity of the equipment linked to the NFT, and 2 Reduction power management unit 11f-3b CO 2 The status management unit 11f-1a extracts the reduction power and calculates the CO 2 The status relating to the reduction is extracted, the cheer information management unit 11f-2a extracts cheer information relating to the cell (number of cheers, etc.), and the donation information management unit 11f-2b extracts donation information (amount of donation, etc.).

[0073] Next, the generation unit 11i generates display data related to the management information extracted by the management unit 11f (S24), and the transmission / reception control unit 11a transmits the display data to the user terminal 2 via the communication unit 12 (S25). In the user terminal 2, under the control of the control unit 21, the management information related to the identified cell on the map is displayed on the display unit 24 so that it can be confirmed (S27). In this way, the process related to viewing the management information is completed.

[0074] Here, the management information viewing screen displayed on the user terminal 2 is, for example, as shown in Fig. 8. As shown in the figure, the specified cell is highlighted on the map, and the latitude, longitude, address, status, CO of the facility in the cell are displayed below. 2 Reduction power, number of cheers, donation amount, etc. are shown.

[0075] Furthermore, by transitioning to the screen in Fig. 9, it is possible to check more detailed management information than the screen in Fig. 8. The screen in Fig. 9 further displays the number of cheers and donation amounts related to the cell, the number of NFTs (facilities) linked to the cell, etc. If corporate PR is set for the identified cell, the logo of the company supporting the cell may be displayed and a link may be provided, and if a specific campaign is set, the details of the campaign may be displayed.

[0076] Therefore, on a cell-by-cell basis, CO 2 It is expected that collaboration will accelerate the realization of a carbon-free society, as participants will be able to confirm the results of their reduction efforts and act as a bridge between companies and NFT owners that are rooted in the cell (region), and participation in the platform itself will help them realize that they are making a significant contribution to environmental improvement, which will increase their motivation and invigorate their activities.

[0077] Next, with reference to the flowchart of FIG. 7, the process flow relating to the updating of cheer information, donation information, etc., by utilizing cheers in the transaction system will be described.

[0078] In the user terminal 2, a cell on the map is selected (S31), and when a cheer is instructed for the cell (or an NFT (equipment) linked to the cell), the cheer instruction is transmitted to the management server 1 via the communication unit 22 under the control of the control unit 21 (S32). Then, in the management server 1, the transmission / reception control unit 11a receives the cheer instruction (S33), the cheer information management unit 11f-4 updates the cheer information included in the management information of the management information storage unit 18 (S34), the calculation unit 11g calculates the donation amount based on the cheer points consumed in accordance with a predetermined rule (for example, a predetermined percentage of the cheer points), and the donation information management unit 11f-5 updates the donation information included in the management information of the management information storage unit 18 (S35).

[0079] In this way, the display unit 11i generates display data based on the updated management information, and under the control of the transmission / reception control unit 11a, a notification of the update is sent to the user terminal 2 via the communication unit 12 (S36). In the user terminal 2, under the control of the control unit 21, display is performed on the display unit 24 based on this display data (S36). This completes the series of processes.

[0080] A series of confirmation screens for the updated registered information on the user terminal 2 are shown in Fig. 10. It becomes possible to confirm the updated contents such as CO2 reduction power, number of cheers, number of cells that have achieved CN, donation amount, number of facilities, etc. When giving the cheers, the user can select the desired donation destination on the screen shown in Fig. 11.

[0081] As described above, according to the embodiment of the present invention, the following effects are achieved.

[0082] That is, according to an embodiment of the present invention, there is provided a trading system comprising a management server 1 and a blockchain 5, in which the management server 1 communicates with a user terminal 2 and a corporate server 3, issues a non-fungible token on the blockchain 5 for a digital twin generated based on at least equipment information transmitted from the corporate server 3, executes a transaction relating to the non-fungible token with the user terminal 2, grants cheer points to the user terminal in association with the transaction, manages the non-fungible token in association with cells obtained by subdividing a region into predetermined units, and, when an cheer is made for a cell by the user terminal 2, a trading system is provided comprising a control unit that controls the allocation of a portion of the cheer points of the cheer to a donation.

[0083] Therefore, by making it possible to trade NFTs issued for digital twins of facilities and other things toward a carbon-free society, users' participation in the service will itself become an activity for improving the environment, making ordinary consumers part of the effort toward a carbon-free society, raising awareness, and providing society with a system that benefits companies, users, and operators.

[0084] Furthermore, it will be possible to divide the region into specified units using cells on the map and visualize the results of efforts toward a carbon-free society for each cell, which will increase the motivation of companies with roots in the region and users who have an emotional attachment to the region, and further promote their efforts.

[0085] In addition to the above, various platforms utilizing blockchain and other technologies are being realized every day, and the power consumption associated with operating these platforms is enormous. In order to improve the environment, it is desirable to take measures and considerations regarding this power consumption. According to an embodiment of the present invention, by allocating a portion of the investment in NFTs to donations, it is possible to provide technology that takes into consideration the impact on the environment due to the power consumption associated with platform operation.

[0086] Furthermore, digital twins can also include content from anime and game characters, making it possible to reach a wide range of users depending on the selection.

[0087] Although the embodiment of the present invention has been described above, it goes without saying that the present invention is not limited to this embodiment and various improvements and modifications can be made without departing from the spirit and scope of the present invention.

[0088] For example, we can expect the expansion of services by combining it with regional revitalization (hometown tax donations), the possibility of linking digital twins with Japanese anime and game characters, and the ability to target facilities around the world. [Explanation of symbols]
