<Overview of the system>
FIG. 1 is a diagram showing an example of the overall configuration of a transaction support system according to one embodiment of the present invention. The transaction support system of this embodiment includes a management server 2 . The management server 2 is communicably connected to the user terminal 1 via a communication network. The communication network is, for example, the Internet, and is constructed by a public telephone line network, a mobile telephone line network, a wireless communication path, Ethernet (registered trademark), and the like. Management server 2 is also communicatively connected to blockchain network 3 .

The blockchain network 3 is composed of a plurality of nodes (computers) and can manage ledger data in a distributed manner. Distributed ledgers are managed by a so-called blockchain mechanism that makes falsification difficult. Note that the detailed explanation of the distributed ledger management mechanism by blockchain is omitted here as it adopts a general one. Blockchain network 3 can be constructed by, for example, Ethereum.

Tokens (Ethereum tokens) that can be issued by the blockchain network 3 such as Ethereum include fungible tokens and non-fungible tokens (Non-Fungible Tokens: NFT). NFTs are non-fungible tokens, unlike fungible tokens. NFTs can have unique values that distinguish them from other NFTs. For this reason, an NFT has a unique identifier (NFT-ID) to allow distinguishing it from other NFTs. NFT is, for example, a token issued according to the ERC (Ethereum Request for Comments) 721 standard. An NFT conforming to the ERC721 standard is also called an NFT-721 token. In this embodiment, as an example, assume that the NFT is an NFT-721 token. NFTs, like fungible tokens, can be traded on the blockchain network 3. The NFT transaction history is recorded in the blockchain network 3. The distributed ledger of the blockchain network 3 also records the owner of the NFT and its ownership history.

In the transaction support system of the present embodiment, based on digital content (hereinafter simply referred to as content) such as images (including still images and moving images), characters and items used in games, and music (audio data). It is assumed that digital assets will be issued through In this embodiment, digital assets are assumed to be NFTs.

In addition, the transaction support system of the present embodiment provides periodic rewards to NFT owners. Further, in the transaction support system of the present embodiment, a periodical system usage fee is collected from the owner of the NFT.

The user terminal 1 is a computer operated by a user who can be the owner of the NFT. The user terminal 1 is, for example, a smart phone, a tablet computer, a personal computer, or the like. A user can purchase an NFT using the user terminal 1 and sell the NFT on the market.

The management server 2 is a computer that issues, sells, and trades NFTs. The management server 2 may be a general-purpose computer such as a workstation or personal computer, or may be logically realized by cloud computing.

<Management server>

FIG. 3 is a diagram showing a software configuration example of the management server 2. As shown in FIG. Note that the illustrated configuration is an example, and other configurations may be employed. The management server 2 includes an NFT issuing unit 211 , reward granting unit 212 , NFT usage processing unit 213 , price acquisition unit 214 , usage fee collection unit 215 , NFT transfer processing unit 216 , and reward storage unit 231 .

The reward storage unit 231 stores information on rewards given to users (hereinafter referred to as reward information). The reward information includes information for identifying content (content identification information), conditions for events to occur (event conditions), and rewards given to users when the event conditions are met for the content. can be included. Content identification information is information for identifying one or more pieces of content. For example, a condition for content may be content specifying information. The event may be an event within the system or an event outside the system. An event within the system may be, for example, the passage of time. For example, the event condition can be that a predetermined period of time has elapsed since the previous reward was given. For events outside the system, an event registration unit may be provided for registering events that have occurred. The event outside the system may be, for example, the sale of a predetermined number or amount of content, or the holding of a live performance or distribution related to the content. Multiple event conditions can be set.

The NFT issuing unit 211 issues an NFT. The NFT issuing unit 211 can issue an NFT in response to a request. The request may include a user ID that identifies the user and a content ID that identifies the content. The NFT issuing unit 211 issues an NFT (for example, the content ID can be set in the metadata of the NFT) that is linked to the content ID specified in the request in the blockchain network 3, and the user's wallet can be stored in

In addition, the NFT issuing unit 211 can issue an NFT by setting the contents of the reward and the conditions for granting the reward to the NFT. The NFT issuing unit 211 can read the reward information corresponding to the designated content from the reward storage unit 231 and set the event condition and reward content of the read reward information in the meta data of the NFT.

The NFT usage processing unit 213 can allow the content linked to the NFT to be used. The NFT usage processing unit 213 can, for example, allow a user other than the owner to use the content linked to the NFT. The NFT usage processing unit 213 can, for example, lend content to the user. The NFT usage processing unit 213 can, for example, allow the user to view the content. The NFT usage processing unit 213 can, for example, display the content linked to the NFT to the public and display an advertisement.

The compensation acquisition unit 214 can acquire compensation for using NFT. The consideration acquisition unit 214 can acquire usage consideration by, for example, performing billing processing on the user. Further, when the content is publicly displayed and an advertisement is displayed, the consideration acquisition unit 214 can acquire advertising revenue related to the advertisement. In addition, the compensation acquisition unit 214 can also obtain profits such as tipping for public display of the content linked to the NFT, for example.

The reward giving unit 212 gives a reward to the owner of the NFT. The reward granting unit 212 can identify the owner of the NFT (the address of the wallet storing the NFT) from the blockchain network 3. The reward granting unit 212 can periodically grant a reward every hour, every day, every week, every month, or every year, for example. The reward granting unit 212 can, for example, grant the user a benefit that is periodically granted by the system operator. In addition, the reward giving unit 212 can give the user a privilege given by the content seller.

For example, the reward granting unit 212 can grant a reward corresponding to the value obtained by multiplying the value of the NFT by an interest rate (which may be specified in advance or may be set by the operator at any time or periodically). . The value of NFTs can be expressed, for example, in fiat currency or virtual currency amounts. The value of the NFT may be the selling price or the market price of the NFT. The market price may be calculated, for example, as a statistical value (average value, median value, etc.) of the transaction prices of NFTs in the same category, or may receive an input of a value expected from market participants. good. The reward granting unit 212 can pay the amount obtained by multiplying the value of NFT by the interest rate in legal currency or virtual currency. The reward granting unit 212 can grant other digital assets (for example, equipment, costumes, goods, etc. that can be worn by a character tied to the NFT) having a value obtained by multiplying the value corresponding to the value of the NFT by an interest rate. can.

The reward granting unit 212 can, for example, pay at least part of the fee for using the content tied to the NFT to the owner as a reward. The reward granting unit 212 can, for example, perform a process of inviting the user to an event in which only NFT owners can participate. The reward giving unit 212 can give rewards to users according to reward information registered in the reward storage unit 231 . That is, the reward giving unit 212 can give a reward according to fulfillment of a preset event condition.

The reward granting unit 212 may reward past owners of NFTs. The reward granting unit 212 can trace the history of NFT-related transactions from the blockchain managed by the blockchain network 3 and identify past owners. The reward granting unit 212 asks all past owner users who were owners during a predetermined period (from the current time to the current time point, or from the time point in the past). Rewards can be given to users or to users of past owners who meet predetermined conditions. Also, the reward giving unit 212 may give different rewards depending on, for example, when the NFT was owned. For example, the reward may be calculated so that the interest rate is higher for the most recent user. The reward granting unit 212 may give the past owner the same reward given to the current owner, or may give the past owner a reward different from the reward given to the current owner. You can give it. Also, the reward granting unit 212 may distribute the reward to be granted to the current owner and past owners.

The usage fee collection unit 215 charges the system usage fee to the user. The usage fee collection unit 215 can periodically charge the user a fixed usage fee, for example, every month. For billing processing, for example, known methods such as sending a request to a settlement server operated by a settlement company (funds transfer company, receiving agent, issuer of prepaid payment means, financial institution, credit card company, etc.) The details are omitted here.

The NFT transfer processing unit 216 performs processing for transferring the NFT. The NFT transfer processing unit 216 can perform processing for transferring the NFT in response to a request to transfer the NFT. The request includes an NFT-ID that identifies the NFT and information that identifies the destination user (eg, wallet address, etc.). The NFT transfer processing unit 216 identifies the owner of the NFT indicated by the NFT-ID from the blockchain network 3, and issues a transaction to transfer the NFT from the wallet of the identified owner to the wallet of the destination user. By doing so, the NFT can be transferred.
