FIG. 1 is a diagram showing an example of the overall configuration of a transaction support system according to an embodiment of the present invention. The provision system of this embodiment is configured to include a server device 1. The server device 1 is communicably connected to the user terminal 2 via the communication network NW. The communication network NW is, for example, the Internet, and is constructed from a public telephone line network, a mobile phone line network, a wireless communication path, Ethernet (registered trademark), and the like.

The digital products of this embodiment include images, videos, audio, etc., and also include art works, characters, digital items, etc., but are not limited to these. Furthermore, ownership of the digital product can be shared among multiple users. Ownership can be exhibited as multiple editions (for example, the number of exhibits is 100), and each edition is associated with an NFT-ID. Digital products purchased by a user can be resold to other users through methods such as auctions, and each time a user acquires ownership of a digital product, the digital signage attached to the digital product or the website related to the digital product can be resold to other users. You can also display the user's name on the page.

In this embodiment, the digital product is sold with a right (or benefit) that includes a target product (a product that actually exists) or the right to purchase the target digital product that is linked to the digital product. When trading the target product, the user can purchase the digital product. The digital product is managed in association with an NFT as unique data, and the information on the exercise of the purchasing right and the remaining purchasing right can be recorded in advance as an NFT on the blockchain network, or can be recorded when the user exercises the purchasing right.

Furthermore, the digital product of this embodiment is sold with the right and benefit to purchase the target product (which may be an actual product or a digital product) linked to the digital product. Good too. The user can purchase the digital product when trading the target product.

The server device 1 is also communicably connected to a blockchain network (Blockchain NW in FIG. 1). A blockchain network is composed of multiple nodes (computers) and can manage ledger data in a distributed manner. Distributed ledgers are managed using a so-called blockchain mechanism to make them difficult to tamper with. Note that a detailed explanation of the blockchain-based distributed ledger management mechanism will be omitted here as a general one will be adopted. A blockchain network can be constructed using Ethereum, for example.

Tokens (Ethereum tokens) that can be issued by blockchain networks such as Ethereum include fungible tokens and non-fungible tokens (NFTs). NFT is, for example, a token issued by Etherium, a blockchain network platform, in accordance with the "ERC721" or "EIP-4907" standards, and is a unit of data recorded on the blockchain network, with a unique It can be associated with the edition (ownership) of a digital product based on its identifier (NFT-ID), and has a non-fungible character. NFTs can have unique value that distinguishes them from other NFTs. In this embodiment, as an example, it is assumed that the NFT is an NFT-721 token or an EIP-4907 token, but is not limited thereto. NFTs, like fungible tokens, can be traded on blockchain networks. NFT transaction history is recorded on a blockchain network. The distributed ledger of the blockchain network also records the owner and ownership history of the NFT.

FIG. 2 is a diagram showing an example of the hardware configuration of the server device 1. Note that the illustrated configuration is an example, and other configurations may be used. The server device 1 includes a CPU 101, a memory 102, a storage device 103, a communication interface 104, an input device 105, and an output device 106.

FIG. 7 is a diagram explaining the operation of the transaction support system of this embodiment.

The server device 1 sells products (1001). The product is a digital product that comes with the right to purchase the target product. The server device 1 issues an NFT corresponding to the digital product when acquiring product purchase application information (or information on completion of purchase payment) (1002). The server device 1 receives an application for rental of a product and processes the rental (1003). The server device 1 sells the target product to users who have legitimate rights (1004). Eligible products are those that are subject to purchase rights attached to the product. The server device 1 acquires information such as the number of times the purchase right has been exercised (1005). The server device 1 acquires the online behavior information of the lender user (1006). The server device 1 provides a reward to the lender user based on the purchase right exercise status and the online behavior information of the lender user (1007).

As described above, the transaction support system of this embodiment provides a new user experience for selling target products through product rental.

In this embodiment, an example of a digital product with the right to purchase the target product has been described as a product, but other rights may be attached to the digital product. The other rights include, but are not limited to, rights held by the user who owns the target product, such as the right to use, use right, disposal right, and naming right for the target product.

In this embodiment, an example has been described in which a user rents products (a digital product and the right to purchase the target product), but it is also possible to rent only rights such as the right to purchase the target product.

Rights may take various forms. For example, the content of the rights may be different between the user who purchased the product (lender user) and the renter user who rented the product. For example, a lessor user may be able to purchase an unlimited number of target products, and a lessee user may be limited in the number of target products he or she can purchase. Further, for example, the number of products that can be purchased within a predetermined period may be different between the lender user and the borrower user. Further, for example, the purchase price of the target product may be different between the lender user and the borrower user.

The rental management department 113 may divide and rent the product to be rented. The rental management unit 113 may divide the product into a digital product and the granted rights such as purchase rights, and may rent each separately, or may rent only the rights such as purchase rights. Furthermore, the rental management unit 113 may divide and rent rights such as purchase rights, and divide the rights, for example, at a ratio of 8:2, and the renter who rented 8 rights and 2 rights. When the parties exercise their rights, the subject product sales department 114 may sell the subject products at different purchase prices.

The rental management unit 113 may accept settings for rental conditions from the user. For example, the rental management unit 113 may receive information such as a rental period, rental cost, rental target, and target division ratio from the user, and may present the information to the renter user as rental conditions.

In this embodiment, an example of acquiring behavioral information of the lender user in an online game has been described, but other online behaviors may be used.

The behavior information acquisition unit 116 may, for example, acquire SNS information of the lender user. The behavior information acquisition unit 116 detects when a lender user is transmitting predetermined information (posting a certain URL, etc.) or spreading predetermined information (including transmitting, retweeting, etc.) on SNS. Behavior information may be acquired and used by the reward providing unit 117 to determine whether to provide a reward.

The behavior information acquisition unit 116 may, for example, acquire information on whether the user has participated in a predetermined event. The behavior information acquisition unit 116 allows users to acquire information such as reception processing from a venue terminal used at an event venue or a server device that is connected to the venue terminal via a network and processes and stores information. Alternatively, participation in a specific event may be determined based on information from a position information acquisition sensor such as a GPS included in the user terminal 2. Further, the server device 1 may obtain information such as information that the user has applied to participate in the event and paid the participation fee/ticket fee. Furthermore, the behavior information acquired in this way may be used by the reward providing unit 117 to determine whether to provide a reward.

The behavior information acquisition unit 116 may acquire information on donations made by the user to a specific organization or initiative. The server device 1 may have a function that allows the user to apply for a donation to a specific organization or initiative, and the behavior information acquisition unit 116 may acquire information about the donation made by the user through the function. Additionally, the server device 1 may obtain information on donations made by a specific user from other websites that accept donations, or may obtain codes or the like that are issued only to users who have accepted donations on other websites. It may also be possible to specify that the user has made a donation by accepting an input. The behavior information acquired in this way may be used by the reward providing unit 117 to determine whether to provide a reward.

For example, the behavior information acquisition unit 116 may acquire information on whether the user has purchased a predetermined product. The predetermined products include, but are not limited to, products for which a portion of the paid price is used to protect nature and wildlife, products with reduced CO2 emissions during manufacturing, and the like. The server device 1 may have a function that allows a user to purchase a predetermined product, and the behavior information acquisition unit 116 may obtain information that the user has purchased a predetermined product through the function. Further, the server device 1 may obtain information that a specific user has purchased a predetermined product from another website where the predetermined product can be purchased, or may acquire information that a specific user has purchased a predetermined product from another website. It may also be possible to specify that the user has purchased a predetermined product by accepting an input such as a code issued only to the user who has purchased the product. The behavior information acquired in this way may be used by the reward providing unit 117 to determine whether to provide a reward.
