It provides a marketplace for transactions. Facilities here conceptually include factories, smart cities, etc.

When general users become digital owners of equipment by purchasing NFTs, they can check the daily _CO2 collection amount of each equipment, acquire value according to the _CO2 collection amount, and utilize the accumulated value. It becomes like this. In this way, the amount of _CO2 recovered by the equipment of which they are the digital owner can be visualized and confirmed on a daily basis, allowing general users to become more familiar with " _CO2 reduction". .

Therefore, it will serve as a bridge between carbon-free hard tech, which was unfamiliar to general users, and will work to change the behavior of people all over the world by shortening the distance between _CO2 recovery equipment and consumers. This will contribute to accelerating the world's movement toward the major goal of realizing a decarbonized society in 2020.

The transaction system according to the embodiment of the present invention operates and manages an NFT marketplace in order to realize the above. The marketplace allows various transactions such as not only buying and selling NFTs, but also reselling NFTs and auctioning them. During the course of transactions on this marketplace, the value of the NFT will increase, and the accumulated value will indicate the status and asset value of the NFT.

FIG. 1 shows and describes the configuration of a trading system according to an embodiment of the present invention.

As shown in the figure, the transaction system according to the embodiment of the present invention realizes NFT transactions related to digital twins of equipment aimed at a decarbonized society. The transaction system includes a management server 1, a user terminal 2, a company server 3, a relay server 4, and a blockchain 5. The management server 1 is connected to a user terminal 2, a company server 3, and a 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, a desktop personal computer, etc. can be adopted.

Here, the term "user" refers to a general consumer who desires transactions such as purchasing NFTs. In FIG. 1, only one user terminal 2 is illustrated, but in reality, a plurality of user terminals 2 exist. On the other hand, "companies" are owners of equipment aimed at a decarbonized society, and entities that wish to trade NFTs related to their own equipment using this service. In FIG. 1, only one company server 3 is shown, but in reality, there are company servers 3 of a plurality of companies.

Blockchain 5 is a system that combines multiple computers that make up a distributed network with cryptographic technology and records NFTs synchronously. In this embodiment, the blockchain 5 may be, for example, a distributed application platform with a smart contract function. However, it is not limited to this, and can be linked with a wide variety of platforms.

In such a structure, if a company that owns equipment, etc. aimed at a decarbonized society wishes to conduct transactions using this service, it will apply for the service. At the time of this application, the company server 3 transmits data related to equipment etc. to the management server 1. When the management server 1 receives this application, it generates a digital twin based on data related to the equipment and the like. Here, a "digital twin" is not just a visual reproduction of equipment for a decarbonized society operated by a company, etc., but also a digital twin that combines the operating information of the equipment, etc. between the real world and the virtual world. This is data that can be synchronized with . In this embodiment, a digital twin is generated based on image data and specification data of equipment for a decarbonized society sent from companies, but this is synchronized with operational data of equipment in the real world. Become something to do.

Subsequently, the management server 1 issues an NFT on the blockchain 5 for the digital twin and performs distributed ledger management. From now on, people who wish to purchase NFTs will generally be recruited in the marketplace operated by the management server 1, and various transactions such as purchases will be executed in response to requests.

When there is a request to purchase an NFT from the user terminal 2, the management server 1 updates the registration information of the NFT, executes a predetermined payment process, and then sends a notification regarding 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 a purchaser to the NFT registration information managed within the management server 1, and is The owner remains the operator. When the management server 1 receives a request for transferring the ownership of the NFT from the purchaser, the management server 1 executes a transaction on the smart contract to transfer the ownership of the NFT.

In companies participating in this service, the company server 3 regularly sends to the relay server 4 operating information on equipment, etc. aimed at a decarbonized society, which has already been converted into an NFT. The relay server 4 compiles and accumulates the operating information individually transmitted from the plurality of company servers 3. The management server 1 reads the accumulated operation information from the relay server 4 at a predetermined timing, calculates the value to be returned to the user who is the NFT purchaser based on the operation information, and returns the user information. Update value information associated with. Users can check the accumulated value at any time on their My Page in the marketplace, and can further utilize the value in electronic payments and the like. Here, the value is any one of points, miles, virtual currency, financial asset token, and in-service currency. For example, points are something that is used on a daily basis, with each 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 merchant.

FIGS. 2(a) and 2(b) show and explain the configuration of the management server of the trading system.

As shown in the figure, the management server includes a control section 11, a communication section 12, and a storage section 13. The control unit 11, the communication unit 12, and the storage unit 13 are communicably connected via a bus line. In addition, it may include an input section such as a keyboard and a mouse, and a display section such as a liquid crystal display that displays various types of information. The communication unit 12 is realized by, for example, a network interface card (NIC), and is connected to a network 6 such as the Internet by wire or wirelessly, and is connected to the user terminal 2, the company server 3, and the relay server 4.

The storage unit 13 is realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory (Flash Memory), a hard disk drive (HDD), a solid state drive (SSD), etc. The controller 11 stores programs to be executed by the controller 11. Here, the storage unit 13 includes, 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, an operating information storage unit 18, and a transaction information storage unit 19. .

That is, in more detail, the user information storage unit 14 is a database that stores the user's name, email address, payment information, transaction history information, value history information, etc. in association with the user ID. The company information storage unit 15 is a database that stores company names, administrator email addresses, payment information, transaction history information (including product IDs), and the like. The digital twin storage unit 16 is a database that stores digital twin information and the like related to the product in association with the product ID. The NFT storage unit 17 stores the product ID, provider (company ID), purchaser (user ID), owner, transaction conditions, and NFT for specifying the digital twin information targeted for the NFT by linking it with the NFT ID. This is a database that stores information such as The operation information storage unit 18 is a database that stores operation information of equipment and the like targeted for NFT in association with NFT IDs. The transaction information storage unit 19 is a database that stores NFT IDs that specify transaction targets, transaction history information, etc. in association with transaction IDs. These are just examples, and it goes without saying that the present invention is not limited thereto.

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

In such a configuration, the transmission/reception control section 11a controls the transmission and reception of data with the user terminal 2, the corporate server 3, etc. via the communication section 12. For example, the transmission/reception control unit 11a may receive a request to purchase an NFT from the user terminal 2 via the communication unit 12, accept a request for a service application from the corporate server 3, or send various requests to the user terminal 2 or the corporate server 3. Control various types of sending and receiving, such as sending notifications.

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

More specifically, as shown in FIG. 2(b), the NFT management unit 11c includes 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 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 registers and manages the issued NFT in the NFT storage unit 17 in association with the NFT ID. 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 state where it cannot be tampered with. For example, when a user who is a purchaser requests a transfer of ownership of an NFT, the transaction execution unit 12c-3 operates on the smart contract of the blockchain 5 to execute a transaction such as transfer of ownership. .

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

The transaction processing unit 11e processes the transactions based on requests from the company server 3 to apply for this service and requests to purchase NFTs from the user terminal 2, updates the registered information in the storage unit 13, and Send notifications regarding transaction completion, etc. to each party. For example, when the transaction processing unit 11e receives a request to apply for this service from the company server 3, the transaction processing unit 11e stores the registered information (transaction history information, etc.) in the company information storage unit 15 and the registration information in the transaction information storage unit 19. Update. On the other hand, when receiving a request to purchase NFT from the user terminal 2, the transaction processing unit 11e updates the registered information (transaction history information, etc.) in the user information storage unit 14 and the registered information in the transaction information storage unit 19 as appropriate. do. The transaction processing unit 11e manages various transactions such as purchase, sale, resale, and auction of NFTs in the marketplace.

When the operation management section 11f receives operation information from the relay server 4 via the notification section 12 under the control of the transmission/reception control section 11a, the operation management section 11f updates the registered information in the operation information storage section 18 based on the operation information. . The value calculation unit 11g reads the registered information in the operation information storage unit 18 at a predetermined timing, and based on the additional operation amount, etc., a new value is added to each NFT under a predetermined calculation formula. The value is calculated, the user information storage section 14 is referred to, and the registered information (value history information) of the user who is the purchaser of the NFT is updated. Since such processing is performed regularly, users can check the current status of the operation of their NFT-compatible equipment and the value returned as a result, thereby contributing to efforts toward a decarbonized society. It is possible to increase the awareness that oneself is participating in the project. 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 the value according to the asset value of the NFT, various campaigns, etc. in addition to the above operation information. More specifically, when calculating the value, it is possible to change the rate depending on the region, or if there is an upper limit on the number of issues, it is possible to change the rate according to market demand and supply.

In addition to the above, the payment unit 11h executes electronic payment when an NFT transaction (for example, purchase) is performed. For example, when an NFT is purchased by the user terminal 2, the registered information (payment information) in the user information storage unit 14 is referred to, and the purchase price is debited or the company that owns the equipment related to the NFT is and perform payment processing for sales consideration. However, it is not limited to this. Generally, in the case of transactions on the blockchain, payments are made via wallets, but in this system, when the owner of the NFT is the operator, the user is managed internally. Payment can be made using general electronic payment, which is convenient for the user.

Note that the management server 1 can be composed of one or more servers. That is, for example, functions related to NFT management and functions related to marketplace management can be distributed to multiple servers to distribute processing.

FIG. 3 shows and describes the configuration of the user terminal of the transaction system.

As shown in the figure, the user terminal 2 includes a control section 21, a communication section 22, an operation section 23, a display section 24, and a storage section 25. Each section 21 to 25 is communicably connected via a bus line. The communication unit 22 is realized by, for example, a NIC, 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 and the like. The operation unit 23 is realized by a mouse, a keyboard, etc., and receives various operation inputs from the user. The display unit 24 is realized by a liquid crystal display or the like, and performs various displays. The operation section 23 and the display section 24 may be integrally configured as a touch panel. The storage unit 25 is realized by, for example, a semiconductor memory device such as a RAM or a flash memory, an HDD, or an SSD, and stores application programs and the like executed by the control unit 21 including a CPU, an MPU, and the like.

The control unit 21 has a web browser function and can utilize the marketplace provided by the management server 1 to execute transactions such as purchasing NFTs. Alternatively, by installing and executing an application program related to transactions in the storage unit 25, the transaction function is realized, and various transactions such as purchasing NFT can be performed using the marketplace provided by the management server 1. become able to.

Hereinafter, the flow of processing related to issuance of NFT by the transaction system will be explained with reference to the flowchart of FIG. 4.

When a request to apply for this service is made from the corporate server 3 (S1), the transmission/reception control unit 11a of 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, specification data, etc. related to equipment for a decarbonized society sent from the corporate server 3 at the time of application, and The twin is registered in the digital twin storage unit 16 (S3).

Subsequently, 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 registers and manages the issued NFT in the NFT storage unit 17 in association with the NFT ID (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 state where it cannot be tampered with (S6).

Next, with reference to the flowchart of FIG. 5, the flow of processing related to NFT transactions etc. by the transaction system will be explained. Here, we will explain the purchase of NFT as an example.

On the user terminal 2, users can check digital twins, purchase conditions, etc. of equipment aimed at a decarbonized society that can be purchased through screens such as those shown in FIGS. 8 and 9. More specifically, the screen in FIG. 8 shows a list of equipment aimed at a decarbonized society that can be purchased with NFTs, and by swiping the top area of the screen, users can switch and check items one by one. Once the object to be considered for purchase is determined, purchase conditions such as price, operating performance of the equipment, etc. can be confirmed on a screen as shown in FIG.

On this screen, when the desired equipment, etc. to be purchased is determined, the purchase button is tapped on the screen of FIG. 9, and a purchase application request is made from the user terminal 2 (S11), in the management server 1, accepts this application (S12). Then, in the management server 1, the transaction processing unit 11e executes processing related to purchase and updates the registered information in the storage unit 13 (S13). More specifically, transaction history information and the like in the user information storage section 14 are updated, and registration information in the transaction information storage section 19 is updated.

In the management server 1, the payment unit 11h executes the payment process associated with the NFT purchase (S14), and the transaction processing unit 11e sends a notification regarding the completion of the transaction to the user terminal 2 (S15). The user terminal 2 can confirm that the purchase has been completed by receiving the notification via the communication unit 22 and displaying the notification content on the display unit 24 under the control of the control unit 21 (S16). .

The flow of processing related to the purchase of NFTs has been described above, and the transaction processing unit 11e executes the processing for reselling and auctioning NFTs using substantially the same procedure. For example, in the case of an auction, the user who bids the highest price during a predetermined bidding period will be permitted to purchase, and the above-mentioned procedure will be executed.

Next, with reference to the flowchart of FIG. 6, the flow of processing related to value return, etc. accompanying the operation of NFT-related equipment by the transaction system will be explained.

The corporate server 3 periodically transmits operation information of equipment aimed at a decarbonized society, which is converted into NFT and traded on the marketplace, to the relay server 4 (S21). Upon receiving this operating information, relay server 4 updates the registration information (S22). The relay server 4 accepts and processes (sends) the reading of the operating information by the management server 1 (S23).

In the management server 1, the transmission/reception control section 11a acquires this operation information (S24), and the operation management section 11f updates the registered information in the operation information storage section 18 (S25). The value calculation unit 11g reads the registered information in the operation information storage unit 18 at a predetermined timing, and based on the additional operation amount, etc., a new value is added to each NFT under a predetermined calculation formula. The value is calculated (S26), and the registered information (value history information) of the user who is the purchaser of the NFT is updated with reference to the user information storage unit 14 (S27). Here, "value" is any one of points, miles, virtual currency, financial asset token, and in-service currency. Of course, the value calculation unit 11g may calculate the value according to the asset value of the NFT, various campaigns, etc. in addition to the above operation information. More specifically, when calculating the value, it is possible to change the rate depending on the region, or if there is an upper limit on the number of issues, it is possible to change the rate according to market demand and supply.

This updated content can be confirmed as appropriate on the My Page of the marketplace operated by the management server 1, for example, in the screen formats shown in FIGS. 10 and 11. In the example of FIG. 10, the CO ₂ recovery history and the value given accordingly are shown. Furthermore, in the example shown in FIG. 11, it is possible to check chronological changes in operating performance, changes in value assigned accordingly, history of value acquisition, etc.

Next, with reference to the flowchart of FIG. 7, the flow of processing related to NFT ownership transfer etc. by the transaction system will be explained.

When a request for NFT ownership transfer is made from the user terminal 2 (S31), the transmission/reception control unit 11a of the management server 1 accepts this request (S32), and the transaction execution unit 11c-4 of the NFT management unit 11c , executes an ownership transfer transaction for the smart contract of blockchain 5 (S33). As a result, in the blockchain 5, the contents (owner) of the smart contract are rewritten (S34).

Next, in the management server 1, the NFT registration unit 11c-2 updates the registration information in the NFT storage unit 17 (S35), and the NFT registration unit 11c-2 notifies that the rewriting of the ownership of the NFT has been completed. is transmitted to the user terminal 2 (S36). This notification includes the public address of the NFT on the blockchain 5, etc.

The user terminal 2 receives this notification via the communication unit 22, and displays the content of the notification on the display unit 24 under the control of the control unit 21 (S37). With this notification, the user obtains the public address on the blockchain 5 of the NFT of which he or she is the owner, so that he or she can directly check the contents of the NFT from now on.

As explained above, according to the embodiment of the present invention, the following effects are achieved.

First, it is a transaction system equipped with a management server and a blockchain, where the management server communicates with user terminals and a company server, and about digital twins generated based on equipment information sent from the company server. Non-fungible tokens are issued on the blockchain, transactions related to the non-fungible tokens are executed with user terminals, and the value is calculated based on the operation information of the equipment related to the non-fungible tokens sent from the company server. A transaction system is provided that includes a control unit that calculates the value of non-fungible tokens and assigns value to purchasers of non-fungible tokens.

Therefore, we will realize transactions of NFTs issued for digital twins of equipment, etc. aimed at a decarbonized society, and value will be given to the purchaser depending on the operating status of the equipment after the transaction. As a member of efforts toward a decarbonized society, it will be possible to raise awareness and provide society with a system that benefits companies, users, and operators. Note that the digital twin can also include the content of anime and game characters, so depending on the selection, it becomes possible to reach out to a wide range of users.

Here, when the control unit receives a request related to the transfer of ownership of a non-fungible token from a purchaser, it sends a transaction related to the ownership transfer to the smart contract associated with the non-fungible token on the blockchain. Execute.

Therefore, at the time of purchase, the relationship between the NFT and the purchaser is managed by the internal management of the management server, but if a request is received from the user to transfer the ownership of the NFT, the blockchain By executing a transaction against the property, ownership can be quickly transferred.

Although the embodiments of the present invention have been described above, the present invention is not limited thereto, and it goes without saying that various improvements and changes can be made without departing from the spirit thereof.

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