[System configuration]
FIG. 1 is a diagram illustrating an example of the configuration of a content system 1 according to this embodiment. The content system 1 can communicate with a content execution system 10 that executes a program that realizes a content service based on one or a plurality of content data 80 related to predetermined content (in this embodiment, a game, as will be described later). Block chain system 20 composed of a plurality of nodes 7 is included.

The content execution system 10 includes a content data management device 30 that executes a program that performs various processes using content data 80, and a content data management device 30 that is used by a user of the content and is communicably connected to the content data management device 30. Alternatively, it includes a plurality of user terminals 40 (smartphones, personal computers, etc.).

The content data management device 30 and the user terminal 40 are communicably connected by a wired or wireless communication network 5 such as a LAN (Local Area Network), a WAN (Wide Area Network), or the Internet.

In this embodiment, the content execution system 10 is assumed to be a game execution system that uses content data 80 relating to games. That is, the content data management device 30 stores a predetermined game program. In order to execute the game program of the content data management device 30, the user (user terminal 40) must be registered in advance with the content data management device 30 or the like.

In response to a request from each user terminal 40, the content data management device 30 stores cards, items, etc. that can be used in the game as content data 80 that can be used by the user (to be lent to the user). , create and register various data such as characters, monsters, and avatars. Each user terminal 40 appropriately uses the registered content data 80 to execute the game program of the content data management device 30, thereby performing actions such as fighting with other user terminals 40 (users). In addition, each content data 80 has unique attribute information (for example, points, ability, value). is changed (for example, the value increases or decreases).

On the other hand, in the blockchain system 20 , each node 7 can share the token 70 . This token 70 is a token with each content data 80 as an asset, and is shared among nodes 7 as blockchain data. The node 7 that configures the blockchain system 20 includes the user terminal 40 , but may include a terminal different from the user terminal 40 .

The token 70 of the blockchain system 20 includes a history of asset ownership (asset owner) transfer and a smart contract, which is a function capable of executing processing such as asset transactions. I'm in. This token 70 is a Non-Fungible Token (NFT) whose value varies depending on the attribute of the asset or its owner. The content data management device 30 is communicably connected to the block chain system 20 with the same configuration as the communication network 5 , and the content data management device 30 issues this token 70 to the block chain system 20 .

Note that the blockchain system 20 is realized using, for example, Ethereum, but other platforms may be used as long as each function described below can be implemented.

Next, FIG. 2 is a diagram for explaining an example of functions provided in the content data management device 30. As shown in FIG. The content data management device 30 includes a content data creation unit 31 , a token issuing unit 33 , a content execution unit 35 and a data acquisition unit 37 .

The content data creation unit 31 creates content data 80 that is used by the user in processing of a predetermined content service. In this embodiment, the content data creation unit 31 creates cards, items, characters, or the like used by the user in the game program in response to a request from each user terminal 40 . The content data creating section 31 stores the created content data 80 as the content data information 50 .

The content data information 50 includes a data ID 51 assigned to each content data 80, and a user 53 of the content data 80 associated with the data ID 51 (the user or user terminal 40 who received the content data 80 from the content data management device 30). , attributes 55 (for example, points, ability, value) of the content data 80 associated with the data ID 51, and issuance information 57 indicating whether or not the content data 80 associated with the data ID 51 has been issued as a token 70, are stored in the data record. (Note that the issuance information 57 may be unnecessary as described later). In this embodiment, "Yes" is set in the issue information 57 when the token 70 is issued, and "No" is set in the issue information 57 when the token 70 is not issued. .

The token issuing unit 33 creates a token 70 based on the content data 80 in the content execution system 10 and issues it to the blockchain system 20 (for example, by registering the token 70 in the user's account or wallet). ), to share the information of the token 70 with each node 7 .

Specifically, when the token issuing unit 33 determines that the content data 80 such as items and characters satisfies a predetermined condition in processing of the game program, the token issuing unit 33 A token 70 storing ownership rights of 80 users is created, and the created token 70 is issued in the blockchain system 20. This token 70 is shared by each node 7 of the blockchain system 20 .

The content executing unit 35 executes a game program, which is a content service, using content data 80 of each user (user terminal 40) as an input value. Specifically, the content execution unit 35 executes a content service (game program), which is a service for executing processing according to the content data 80 when the content data 80 is input. Also, the content execution unit 35 executes the game program (each module) and changes the attribute value of each content data 80 according to the execution result (output value, etc.).

When the content execution unit 35 executes the game program based on the content data 80, the data acquisition unit 37 obtains the information of the content data 80 or the corresponding token 70 from the content execution system 10 or the blockchain system 20, respectively. get.

That is, the data acquisition unit 37 determines whether or not the token 70 corresponding to the content data 80 has been issued when executing the processing of the content service regarding the content data 80, and determines whether the token 70 has already been issued. If determined, the information of the token 70 including the information of the asset corresponding to the content data 80 is acquired, the processing of the content service 80 is executed based on the acquired information, and it is determined that the token 70 has not yet been issued. In this case, the content data 80 is acquired, and the processing of the content service is executed based on the acquired content data 80 .

Next, FIG. 3 is a diagram showing an example of the configuration of the token 70 in the blockchain system 20. As shown in FIG. The token 70 stores a transaction execution part 71 and asset information 73 .

The transaction execution unit 71 executes ownership transfer of the token 70 between accounts of the nodes 7 of the blockchain system 20 . The specific form of this transfer transaction is not particularly limited. For example, it may be a transaction in which a predetermined cryptocurrency (such as Ether) is used as consideration, or it may be a transfer without consideration.

The asset information 73 is information of an asset corresponding to the content data 80. Specifically, the asset ID 75 (corresponding to the data ID 51 of the content data information 50) and the attribute 77 of the asset related to the asset ID 75 (the content data information 50 (history of information corresponding to the attribute 55 of the content data information 50 is set in chronological order), and the ownership transfer history 79 of the asset related to the asset ID 75 (history of information corresponding to the user 53 of the content data information 50 is set in chronological order). is set). Note that the token 70 is implemented as, for example, a smart contract.

Here, FIG. 4 is a diagram showing an example of hardware included in each information processing device (the content data management device 30, the user terminal 40, the node 7) in the content system 1. As shown in FIG. Each information processing device includes a processing device 91 such as a CPU (Central Processing Unit), a main storage device 92 such as a RAM (Random Access Memory) and a ROM (Read Only Memory), a HDD (Hard Disk Drive), an SSD (Solid state drive), an input device 94 comprising a keyboard, mouse, touch panel, etc., an output device 95 comprising a monitor (display), etc., and a communication device 96 for communicating with other information processing devices. Prepare. The functions of each information processing device described above are implemented by the hardware of each information processing device, or by a program (smart contract, etc.) stored in the main storage device 92 or auxiliary storage device 93 by the processing device 91 of each information processing device. is realized by executing In addition, these programs are, for example, storage devices such as secondary storage devices, nonvolatile semiconductor memories, hard disk drives, and SSDs, or IC cards, SD cards, DVDs, and other non-temporary programs that can be read by each information processing device. stored on a physical data storage medium.
Next, processing executed by the content system 1 will be described.

--process--
FIG. 5 is a flowchart for explaining the outline of the processing executed by the content system 1. As shown in FIG. The content system 1 is repeatedly executed, for example, when the content data management device 30 starts executing the game program.

First, the content data management device 30 specifies a process to be currently executed (hereinafter referred to as a target process; for example, a program component such as a function or module) based on a scenario defined by the game program (s1). Then, the content data management device 30 executes a data acquisition process of acquiring the content data 80 necessary for executing the target process or the data of the token 70 corresponding to the content data 80 from the content data management device 30 or the blockchain system 20. (s3). Details of the data acquisition process will be described later.

The content data management device 30 executes the target process based on the data acquired in s3 (s5).

Further, the content data management device 30 executes a token issuing process to convert the content data 80 that satisfies a predetermined condition among the content data 80 stored therein into a token 70 and deploy it in the blockchain system 20 (s7). Details of the token issuing process will be described later.

The above processing of s1 to s7 is repeated as needed. Note that the order of the processes described here is merely an example, and the order of the processes is arbitrary. For example, the token issuing process may be executed at predetermined timings (eg, predetermined time intervals, predetermined times) independently of the processes s1 to s5.
Details of the data acquisition process and the token issue process will be described below.

--Data Acquisition Process--
FIG. 6 is a flowchart illustrating an example of data acquisition processing. First, the data acquisition unit 37 identifies the content data 80 (hereinafter referred to as target data) used when executing the target process (s31). For example, the data acquisition unit 37 acquires, from the content data information 50, a record in which the data ID 51 of the content data 80 to be input to the target process is registered.

The data acquisition unit 37 determines whether or not the target data acquired in s31 has been issued as the token 70 (s33). For example, the data acquisition unit 37 checks whether the issue information 57 of the record acquired in s31 is "Yes".

If it is determined that the target data has been issued as the token 70 (s33: YES), the data acquisition unit 37 executes the processes of s35 and s37, and if it is determined that the target data has not been issued as the token 70 (s33: NO), the data acquisition unit 37 executes the process of s39.

In s35 to s37, the data acquisition unit 37 acquires data of the token 70 shared by the blockchain system 20. FIG.

That is, the data acquisition unit 37 acquires information on the owner user of the asset related to the target data from the token 70 of the blockchain system 20 (s35). Specifically, the data acquisition unit 37 refers to the ownership transfer history 79 of the token 70 whose asset ID 75 is the same as the data ID 51 of the target data, and obtains the information of the user who currently owns the asset. to get

Also, the data acquisition unit 37 acquires information about the attribute of the asset corresponding to the target data from the token 70 of the blockchain system 20 (s37). Specifically, the data acquisition unit 37 acquires current attribute information of the asset by referring to the asset attribute 77 of the token 70 whose asset ID 75 is the same as the data ID 51 of the target data.

On the other hand, in s39, the data acquisition unit 37 acquires the user and attribute information of the target data in the content data information 50. FIG. Specifically, the data acquisition unit 37 acquires the user 53 and the attribute 55 of the record acquired in s31 from the content data information 50 . The data acquisition process ends here.

--Token issuance process--
FIG. 7 is a flowchart illustrating an example of token issuing processing. First, the token issuing unit 33 selects content data 80 (hereinafter referred to as subject content data) to be subjected to token issuing processing. For example, the token issuing unit 33 acquires the attribute of the subject content data by referring to the attribute 55 of the record of the content data information 50 in which the data ID 51 of the subject content data is registered (s71).

The token issuing unit 33 determines whether or not the attribute of the subject content data satisfies the conditions for issuing the token 70 (s73).

In this embodiment, this condition is information related to the game program. or have completed a given scenario of the game. Also, this condition may be a combination of multiple conditions.

If it is determined that the attributes of the subject content data do not satisfy the conditions for issuing the token 70 (s73: NO), the token issuing process ends. If there is content data 80 for which it has not been determined whether or not the conditions for issuing the token 70 are satisfied, the token issuing unit 33 treats the content data 80 as subject content data, and performs the processing from step s71 onward. You can repeat.

If it is determined that the attribute of the content data satisfies the conditions for issuing the token 70 (s73: YES), the token issuing unit 33 issues the token 70 with the content data 80 that satisfies this condition as an asset. It is created and issued to the blockchain system 20 (s75).

Specifically, for example, the token issuing unit 33 sets the data ID 51 of the subject content data to the asset ID 75, sets the user 53 to the ownership transfer history 79, and sets the attribute 55 to the attribute 77 of the asset information 73. , and the transaction execution part 71, and transmits the created token 70 to the blockchain system 20, and registers it in the account or wallet of the user who is the owner of the content data. Each node 7 of the blockchain system 20 shares and stores this token 70 . Further, the token issuing unit 33 sets the content data issue information 57 in the content data information 50 to "Yes".

Before issuing the token 70, the token issuing unit 33 displays a screen for prompting the user to confirm whether or not to actually issue the token 70, thereby confirming the issuance of the token 70 in advance. good too.

Further, when issuing the token 70 , the token issuing unit 33 may add privilege information to the attribute 77 of the token 70 .

With this, the token issuing process ends. If there is content data 80 for which it has not been determined whether or not the conditions for issuing the token 70 are satisfied, the token issuing unit 33 treats the content data 80 as subject content data, and performs the processing from step s71 onward. You can repeat.

After that, each user (user terminal 40) of the blockchain system 20 executes a transaction of the token 70 among the users (nodes 7) participating in the blockchain system 20 by executing the transaction execution unit 71 of the token 70. can do.

For example, the first user (game user) registered with the token 70 through the token issuing process can transfer ownership of the token 70 to other game users participating in the blockchain system 20 . Then, the content data management device 30 recognizes the other game user as the current user of the content data 80 based on the data acquisition process described above, and executes the game program on the premise of this.
In addition, the first user can also transfer the ownership of the content data to a user outside the game, a business operator, or the like participating in the blockchain system 20 . As a result, even a person who is not a game user can acquire the value of this token 70 and make it an object of further transactions.

As described above, the content data management device 30 of the present embodiment creates the content data 80 used in the game content, and when it determines that the content data 80 satisfies the predetermined conditions in the game content, , creates a token 70 that stores the information of the asset corresponding to the content data 80 and the user's ownership of the asset, and transmits the created token 70 to the blockchain system 20 .

In this way, the content data management device 30 can deploy the content data 80 of the game content as the token 70 in the blockchain system 20, so that the content data management device 30 has been closed to the user (loaned to the user) within the game content. The content data 80 can be converted into tokens 70 owned by the user and widely distributed in the blockchain system 20 . As a result, the value of the asset (originally the content data 80) increases, and the attractiveness of the game content to game users and non-game users can be increased.

The description of the embodiments described above is for facilitating understanding of the present invention, and does not limit the present invention. The present invention may be modified and improved without departing from its spirit, and the present invention includes equivalents thereof.

For example, part of the functions of each information processing apparatus described in this embodiment may be provided in another information processing apparatus. For example, the content data management device 30 may be divided into an information processing device having the token issuing section 33 and an information processing device having other functions.

Also, in the present embodiment, the content data management device 30 provides a game as a content service. good. For example, the content data management device 30 provides a user tipping system for a specific event, and when the tipping value exceeds a predetermined amount, information representing the event is generated as a token 70. may be

Further, in this embodiment, the issuance information 57 of the content data information 50 is used to determine whether or not the content data 80 is the token 70, but other methods may be employed. For example, the content data information 50 is not provided with the issuing information 57, and the content data management device 30 deletes the record of the content data information 50 related to the content data 80 when creating the token 70 from the content data 80. may As a result, the information amount of the content data information 50 can be reduced.

At least the following will be clarified by the above description of the present specification. That is, the token management device 30 of the present embodiment determines whether or not a token corresponding to the content data has been issued when executing the processing of the content service regarding the content data, and determines whether the token has already been issued. If it is determined that the token has not yet been issued, the information of the token including the information of the asset corresponding to the content data is acquired, the processing of the content service is executed based on the acquired information, and the token has not yet been issued. If it is determined that the content data is obtained, the method may further include a data acquisition unit that acquires the content data and executes the processing of the content service based on the acquired content data.

In this way, when the token 70 is issued to the blockchain system 20, the ownership and assets are acquired from the token 70 and the content is processed. By executing the processing of the content with the content data management device 30, the content service provided by the content data management device 30 can be seamlessly executed regardless of whether the content data 80 is off-chain (the content execution system 10) or in the blockchain system 20. can be done.

In addition, the content data management device 30 of the present embodiment further includes a content execution unit that executes a game program as the content service, which executes processing according to the content data when the content data is input, The token issuing unit may issue the created token in the blockchain system when determining that the attribute of the content data satisfies a predetermined condition in the game program.

This makes it possible to provide new value related to items and the like to the community outside the game.

Further, the token issuing unit of the token management device 30 of the present embodiment includes a smart transaction execution unit that executes ownership transfer of the token between accounts of the information processing devices that make up the blockchain system as the token. Create a contract.

Thus, by creating the token 70 as a smart contract that transfers the ownership of the token 70 between the accounts of the nodes 7 of the blockchain system 20, the token 70 can be widely distributed.

Further, when the token issuing unit of the token management device 30 of the present embodiment determines that the content data satisfies a predetermined condition in processing of the content service, the token issuance of the created token is It may be issued in a blockchain system that includes an information processing device related to the user.

In this way, since the blockchain system 20 is configured to include the node 7 associated with the user of the content data 80, the user of the content service can access the content not only in the content execution system 10 but also in relation to the blockchain system 20. Data 80 (token 70) can be accessed and used.

Further, as the token management method of the present embodiment, the information processing device (token management device 30) issues a token corresponding to the content data when executing the processing of the content service related to the content data. If it is determined that the token has already been issued, the information of the token including the information of the asset corresponding to the content data is acquired, and the processing of the content service is performed based on the acquired information. If it is determined that the token has not yet been issued, the content data is acquired, and a data acquisition process for executing the content service process based on the acquired content data may be further executed. .

Further, as the token management method of the present embodiment, the information processing device (token management device 30) executes a process corresponding to the content data when the content data is input, a game program as the content service. is further executed, and if it is determined in the token issuing process that the attribute of the content data satisfies a predetermined condition in the game program, the created token is transferred to the blockchain system It may be issued in
