“Content C” is digital data generated by the game server device 20 and whose ownership information is managed on the blockchain. As the content C is generated, an NFT describing the content of the content C and its owner information is generated and registered in the blockchain. Also, when ownership of this content C is traded, this transaction data (transaction) is stored in the block. The owner information includes a guild ID, a player ID, an ownership period, other information when the content C was owned, and the like. In this embodiment, the content C is game data such as items, characters, and monsters that can be used in the game. , general scenery and photo data other than games may be used. Further, when these data (copyrighted works) are produced and provided by the user, the data may be stored not only in the game server device 20 but also in the transaction server device 40 . The data of content C generated by game device 20 may be transmitted to transaction server device 40 and stored. Ownership of content C can be transferred (sales transaction) between game players and traders. In this embodiment, a first content C1, a second content C2, and a third content C3 are exemplified as examples of content C available to players and traders.

"First content C1" is content C that is given as a login bonus (reward) to the player who has started the game. In principle, the first content C1 has attributes, and each first content C1 is unique (managed by NFT), but general-purpose first content C1 without attributes is the same. may be included in the department.

"Second content C2" is content C whose owner is given a profit after a predetermined time has passed since it was generated. The profit is, for example, the third content C3.

"Third content C3" is content C that is given as a profit when the player satisfies a predetermined condition.

A “tower defense game” is an example of a battle game executed between a player who owns the second content C2 and another player who does not play the second content C2, and is an example of a battle game in which players do not invade their own territory (area). It is a defense game that defeats incoming enemies. In a tower defense game, each player is assigned a territory, and in the territory there are walls to prevent invasion from enemy players, buildings (turrets, etc.) to counter enemy players, attack characters, etc. there is Each player uses in-game currency, game items, and the like to develop his own territory and prepares for a battle with an enemy player. A player who wants to acquire the second content C2 can acquire the second content C2 by invading the territory of the player who owns the second content C2 and destroying the castle. On the other hand, the player owning the second content C2 defends the second content C2 by blocking attacks from the enemy player. In this embodiment, it is assumed that a tower defense game for scramble for the second content C2 is played for a predetermined period of time after the second content C2 is generated.

A “fighting game” is an example of a fighting game executed between players, and is a fighting action game in which player characters operated by each player fight against each other in a game virtual space. The fighting means 219 matches the players possessing the first content C1 with each other, and executes the fighting game. The characters of the matched players engage in a fighting match in a predetermined game space.

A “turn-based battle game” is an example of a battle game executed between players, and is a turn-based battle system in which player characters operated by each player alternately act to repeat attacks.

A "friend" indicates a player who is an acquaintance and a friend in the game. When progressing the game with multiple players, cooperative play can be carried out, friends can easily communicate with each other, and items and content C can be exchanged under special conditions.

"Guild" indicates an in-game group to which a player belongs. While interacting with each other in the guild, the guild unit can take on quests to advance the game, and can exchange items and contents C under special conditions like friends.

4. Overview of Information Processing FIG. 5 is an activity diagram showing the flow of information processing in the information processing system 1 according to this embodiment. The flow of information processing will be outlined below along this activity diagram. The information processing method according to this embodiment includes the following steps in the information processing system 1 .

First, the game processing means 115 of the BC node device 10-1 (hereinafter referred to as game terminal 10-1) starts and advances the game based on the operation of the first player (A101). For example, game terminal 10-1 receives data necessary for the game from game server device 20 by transmitting a request to log in to the game to game server device 20. FIG. The game progresses by transmitting and receiving data necessary for the progress of the game between game terminal 10-1 and game server device 20. FIG. The giving means 218 of the game server device 20 gives the first content C1 to the first player at a predetermined timing (A102), and the first player acquires it (A103). Giving means that the first player can use the first content C1 in the game. Along with the provision of the first content C1, a non-substitutable token describing ownership information indicating the owner is issued and registered in the blockchain via the management means 214. FIG. Thereby, the ownership information of the first content C1 is managed on the blockchain with the first player as the owner. That is, the ownership information of the first content C1 is stored on the blockchain.

In addition, the generating means 215 can generate a unique second content C2 by associating the necessary number or more of the first contents C1 owned by the same owner with the necessary number of the first contents C1. If the first player has obtained the predetermined number or more of the first contents C1, the process proceeds to A104. Specifically, the number of first contents C1 required to generate the second contents C2 is, for example, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70. , 75, 80, 85, 90, 95, 100, and may be in the range between any two of the values exemplified herein.

When the first player owns more than the required number of first contents C1, the first player can request the generation of the second contents C2 using the first contents C1 (A104). The accepting means 216 accepts a request for generating the second content C2 from the first player. In addition, when receiving the generation request, the generation means 215 generates unique second content C2 using the required number of first contents C1 (A105). Then, a non-substitutable token corresponding to the second content C2 is issued via the management means 214 and registered in the blockchain. Thereby, the ownership information of the second content C2 is managed on the blockchain with the first player as the owner. That is, the ownership information of the second content C2 is stored on the blockchain.

If the player who requested the generation of the second content C2 possesses the second content C2 at the timing when a predetermined time has passed since the generation of the second content C2 (if he/she is the owner of the second content C2), he/she acquires the privilege. be able to.

Here, another player who desires the second content C2 can make a transfer request to the player who owns the second content C2 until a predetermined time has passed since the generation of the second content C2. When the second player makes a transfer request for the second content C2 (A107), the receiving means 216 receives this (A108). Transfer (ownership of) to another player. More specifically, when receiving a transfer request for the second content C2 from another player, the competition means 219 executes a competition game between the other player and the owner of the second content C2 (A109 ). The battle game executed at this time is, for example, a tower defense game.

As a result of the competition, when another player (second player) wins the competition game, the transfer means 217 transfers the ownership of the second content C2 to the other player (second player) (A110), The player obtains the second content C2 as a reward for winning (A111). At this time, the NFT indicating the owner information of the second content C2 is transferred via the management means 214, and this transfer transaction is registered in the blockchain. When the first player wins the competition game, the ownership (NFT) of the second content C2 is maintained by the first player and is successfully defended.

Thereafter, when a predetermined period of time has passed since the generation of the second content C2, the providing means 218 gives a benefit to the owner of the second content C2 at the time when the predetermined period of time has passed since the generation of the second content C2 (A112). For example, if the first player succeeds in defending the second content C2 until the predetermined time elapses (maintains ownership of the second content C2), the third content C3 is acquired as a privilege ( A113). When the third content C3 (ownership of the third content C3 (NFT)) is acquired, the ownership information is managed on the blockchain in the same way as when the first content C1 and the second content C2 are acquired. Become.

5. Details of Information Processing Next, details of the information processing described above will be further described with reference to FIGS. 6 to 10. FIG. FIG. 6 is an example of a screen displayed on the game terminal 10 and shows the first content C1 given to the first player. FIG. 7 and FIG. 8 are examples of screens displayed on the game terminal 10, and show aspects in which the second content C2 is generated using the first content C1a. FIG. 9 is an example of a screen displayed on the game terminal 10 until a predetermined period of time has passed since the generation of the second content C2. FIG. 10 is an example of a screen displayed on the game terminal 10, showing a mode in which the third content C3 is provided.

First, as the game is started by the game processing means 115 based on the operation of the first player (A101), the generating means 215 gives the first content C1 to the first player (A102). The player who started the game can acquire the first content C1 as a login bonus (A103).

In FIG. 6, the first player has six first contents C1 (a first content C1aa, a first content C1ab, a first content C1b, a first content C1c, a first content C1d, and a first content C1e). ) is given. However, since the first content C1aa and the first content C1ab have the same attribute, there are five kinds of attributes of the first content C1 acquired by the first player.

In particular, when each first content C1 has the same attribute, the player can identify that each first content C1 has the same attribute. In FIG. 6, the first content C1aa and the first content C1ab having the same attribute are shown in the same shape, while the other first content C1 having different attributes have different display modes.

Here, the type of the second content C2 synthesized with the first content C1 as a material, the influence of each of the first content C1 used for synthesis on the in-game potential value of the second content C2, etc. are determined in advance. Although it is defined, it is kept secret from the player. However, since the design (including color and shape) of the first content C1 implies this, and suggestive information 6 such as icons and marks is displayed, the player may use these information as hints. be able to. For example, when the type of the second content C2 generated by the first content C1 is different from the usual one, the suggestive information 6 is displayed together with the first content C1, so that the player can understand that the first content C1 is special. It can be inferred that it is

The generating means 215 can generate a unique second content C2 by synthesizing the required number of the first contents C1 when the same owner owns the required number or more of the first contents C1. Specifically, when the first player owns more than the required number of first contents C1, he/she can request synthesis of the second contents C2 (A104). When the receiving means 216 receives the generation request, the generating means 215 generates the unique second content C2 using the first content C1 (A105). That is, the first player can synthesize the second content C2 by using the first content C1 as a synthesis material by collecting the required number of the first content C1.

As shown in FIG. 7, six pieces of first content C1 having the same attribute are required to generate the second content C2, and the second content C2 can be synthesized using these as materials. As shown in FIGS. 7 and 8, even if the attributes of the first contents C1 used to generate the second contents C2 are the same, the first contents C1 used as materials are different. Content C2 is different and a unique second content C2 is generated.

For example, it is assumed that a plurality of parameters and skills are assigned to the second content C2 to indicate the values and types of abilities to be effective in the game. Each of the first contents C1 serving as materials for synthesizing the second contents C2 is associated with a parameter that affects the second contents C2 and its numerical value. affect each other, and the parameters and skills of the second content C2 change. At this time, the first content C1 as a material may influence the design of the second content C2. In this way, the generating means 215 generates unique second contents C2 by associating the necessary number of first contents C1 with each other by having more than the necessary number of first contents C1 with the same attribute possessed by the same owner. can be generated.

Here, the player can obtain the first content C1 by receiving the transfer of the first content C1 from another player, in addition to obtaining the first content C1 as a login bonus. Specifically, the player wins a match against another player and steals the first content C1, trades with another player, or exchanges the first content C1 to obtain the desired first content C1. can be obtained. At this time, the NFT indicating the owner information of the first content C1 is transferred via the management means 214, and the transfer transaction is registered in the blockchain. As a result, acquisition, transaction, etc. of the first content C1 are established.

For example, when a player wants to steal the first content C1 from another player, the player can challenge the other player to a battle. The battle means 219 matches the players to be battled and causes the battle game to be executed. Depending on the outcome of the match, the transfer means 217 transfers at least one of the first contents C1 possessed by the player who lost the match to the player who won the match. According to this aspect, the winner of the match can deprive the loser of the first content C1. Details of the transfer processing of the first content C1 based on the result of the match will be described later.

Further, when a sales transaction is conducted between players, the transfer means 217 can transfer the first content C1 to be sold and traded to the player who purchased the first content C1. At this time, the player who sells the first content C1 can freely determine the selling price of the first content C1 to be exhibited. Details of the trading process for the first content C1 will be described later.

When players want to exchange the first content C1 with each other, the player discloses to other players the first content C1 that he/she owns and the type of the first content C1 that he or she desires to exchange. and request a transfer. When the transaction is established, the transfer means 217 transfers the first content C1 to be exchanged.

In this manner, the player collects the required number of first contents C1 by various methods and synthesizes the collected first contents C1 to change the plurality of first contents C1 to the second contents C2. On the other hand, the enjoyment of collecting the first content C1 and the enjoyment of synthesizing the collected first content C1 with the second content C2 are provided.

The player who generated the second content C2 can acquire the privilege if he/she possesses the second content C2 when a predetermined time has passed since the generation of the second content C2. The predetermined time is specifically, for example, 1, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24 hours. Also, for example, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60 seconds, and may be within a range between any two of the numerical values exemplified here.

Suggestion information 6 indicating what benefits can be obtained from the second content C2 is displayed, as shown in FIG. 9, until a predetermined time has elapsed since the generation of the second content C2. As a result, the player who owns the second content C2 can guess what kind of privilege will be obtained.

Here, until a predetermined time elapses after the generation of the second content C2, other players who have owned the first content C1 used to generate the second content C2 cannot obtain the second content C2. , the player who owns the second content C2 can apply for a competitive game. When the accepting means 216 accepts the transfer request (A108), if the competing means 219 accepts the transfer request of the second content C2 from another player, the other player and the owner of the second content C2 A battle game is executed (A109).

As a result of the competition, when the other player wins the competition game, the transfer means 217 transfers the second content C2 to the other player (second player) (A110), and the second player obtains it (A111 ). That is, when the player who applied for the competitive game wins, the ownership of the second content C2 is transferred to the winning player, who becomes the owner of the second content C2. As a result, the first player loses the second content C2 to the second player. At this time, the NFT indicating the owner information of the second content C2 is transferred via the management means 214, and this transfer transaction is registered in the blockchain. Thereby, the ownership history (transaction) of the second content C2 is managed on the blockchain. On the other hand, if the possessor of the first content C1 wins the battle game, the property right (NFT) of the second content C2 is maintained by the first player and is successfully defended.

When the second content C2 is stolen by the competitive game, the former owner of the second content C2 can apply for the competitive game to the new owner of the second content C2 in order to regain the second content C2. .

For example, when the ownership of the second content C2 is transferred from the first player to the second player due to the competitive game, the first player can apply for the competitive game to the new owner, the second player. . In this way, the accepting unit 216 receives second content from not only other players who have owned the first content C1 used to generate the second content C2, but also other players who have owned the second content C2. After receiving the transfer request for the second content C2, competition for the second content C2 continues until a predetermined time elapses.

After that, when a predetermined period of time has elapsed, the providing means 218 provides the unique third content C3 to the owner of the second content C2 when the predetermined period of time has passed since the generation of the second content C2 (A112). When the third content C3 is granted, an NFT indicating ownership information of the third content C3 is registered in the blockchain via the management means 214 . In addition, when providing the third content C3, the providing unit 218 deletes the association of the second content C2 from the owner of the second content C2. That is, the player who has acquired the third content C3 loses the ownership of the second content C2, which was the medium for acquiring the third content C3.

Giving means 218 gives a profit to the owner of second content C2 when a predetermined time has passed since the generation of second content C2 (A112). That is, when the first player successfully defends the second content C2 (maintains the ownership of the second content C2) until the predetermined time elapses, the first player acquires the third content C3 as a privilege. When the third content C3 is acquired, its ownership information is managed on the blockchain in the same way as when the first content C1 and the second content C2 are acquired. That is, (the ownership of) the first content C1, which is a material, is transferred from another user, synthesized to change the plurality of first content C1 to the second content C2, and at a predetermined timing, the second content C2 is changed to the second content C2. is changed to the third content C3, and the third content C3 can be used in the game. Thus, the player can be given the pleasure of collecting the first content C1, the pleasure of depriving/preventing the second content C2 from being stolen, and the pleasure of owning the third content C3. Furthermore, since these are managed on the blockchain, fraudulent acts such as falsification will not occur, and users will be able to play games with peace of mind. In the example of FIG. 10, the third content C3 is a character that can be used in the game, but is not limited to this, and may be an item, or image data or video data that the player can view and enjoy. good.

<Modification>
Modifications of the above-described embodiment will be further described below.

In the above example, the first content C1 is given as a login bonus when the player starts the game. . For example, the granting means 218 may grant a reward when the player wins a match against another player or an enemy monster or clears a quest. In addition to the acquisition method described above, the player can obtain the game by various methods such as in-game store (purchase in exchange for payment), trading with other players or external users. However, by allowing the first content C1 to be given to at least one player, by distributing the first content C1 within the game (on the block chain), the player will naturally be able to continue playing the game. preferably obtainable.

Although the example in FIG. 6 shows an example in which the attribute can be identified by the shape of the first content C1, the attribute is not limited to this, and may be identified by an icon or mark displayed together with the first content C1. , character information such as the name and ID of the first content C1. Also, the attribute may include rarity.

In the examples of FIGS. 7 and 8, the first contents C1 used as materials all have the same attribute. General-purpose first content C1 (for example, first content C1e) that does not have the same attributes as first content C1 may be included as part of the composite material.

An example has been shown in which the ownership of the first content C1 used as a material is lost when the first content C1 is synthesized to generate the second content C2. may remain. Also, the first content C1 itself may be a character that can be used in the game.

The second content C2 may be generated according to the attributes of the first content C1 used for synthesis. Further, it may be possible to synthesize the first content C1 using the second content C2 or the third content C3 as a material.

When synthesizing the second content C2, if the material includes the first content C1 that has a history of transactions between players, the game communication means 114 asks the owner who has a history of owning the first content C1 in the past. game terminal 10 may be notified. Here, the “past” may be any person who has owned the corresponding first content C1 at least once. These histories are managed by transactions on the blockchain.

The fighting means 219 executes a fighting game when receiving a transfer request for the second content C2 from another player who owned the first content C1 synthesized when the second content C2 was generated. However, embodiments are not limited to this. For example, regardless of the ownership history, the transfer request is displayed as a list among all players, limited to friends, or limited to guilds according to the attribute (rarity) of the generated second content C2, and can be selected by each target person. may be

Also, when requesting a transfer, the second content C2 having corresponding attributes may be selectable according to the player's residence area (GPS interlocking, registration information), player level, guild level, and the like. Alternatively, the second content C2 desired by the other player may be registered in advance, and at the timing when the second content C2 that matches the registered information is generated, the battle request may be automatically sent to both players.

In the above example, the player can select the type of first content C1 to be transferred according to the result of the match. At least one of the first contents C1 possessed by the player may be randomly transferred. Further, the transfer means 217 may vary the type and number of the first contents C1 to be transferred according to the content of the battle. For example, when players of different levels compete against each other, if a player whose level is lower than that of the opponent wins the competition, the transfer means 217 increases the number of first contents C1 to be transferred, or increases the number of first contents C1 to be transferred. 1 content C1 may be transferred.

In the above example, the case where the providing unit 218 provides the third content C3 to the owner of the second content C2 when the predetermined time has passed since the generation of the second content C2 has been described as an example. Without limitation, the game effect of the second content C2 that has not been used until a predetermined time has passed may be used. For example, the granting unit 218 releases a new ability to the second content C2 after the lapse of a predetermined time.

The granting unit 218 may change the player information related to the win or loss of the competitive game according to the number of owned contents C in the competitive game. "Player information" includes the level, ability value, skill, and game effect given to the player during the battle game of the player or the character possessed by the player. That is, the granting unit 218 grants a game effect according to the number of possessions of the content C. FIG. For example, in the defense game described above, the more the first content C1 or the third content C3 possessed by the player, the more advantageous the player is. C1 or third content C3 itself can be used for a defense game.

The imparting means 218 may impart advantageous game effects to the owner of the second content C2 at the time of synthesizing the second content C2 during execution of the competitive game. That is, the imparting means 218 imparts an advantageous game effect in the competitive game to the player who has generated the second content C2. For example, the granting means 218 increases the number of objects such as weapons and items that can be placed in the defense game, or increases the number of objects such as weapons and items that can be placed in the defense game so that the player can easily successfully defend the second content C2 in the defense game. Raise the character's parameters to prevent Further, the imparting means 218 may impart an advantageous game effect according to the number of synthesized second contents C2. Alternatively, the ability (level) of the attacking side may be adjusted according to the ability (level) of the defending side.

The giving means 218 may give the owner of the second content C2 when a predetermined time has passed since the generation of the second content C2, according to the number of transfers of the second content C2. For example, the providing unit 218 provides the third content C3 with higher parameters as the number of transfers or the transfer rate of the second content C2 decreases. As a result, the player can acquire the third content C3 with a higher ability value as the number of defenses of the second content C2 in the battle game increases. It should be noted that the “number of defenses” referred to here is preferably the number of times the player who acquired the third content C3 himself won the defense game and successfully defended. The "transfer rate" here is preferably the ratio of the number of transfers to the number of defense game executions. That is, when the player who created the second content C2 protects the second content C2 without being stolen by another player, the third content C3 with a high ability value can be acquired. On the other hand, if the second content C2 has been transferred many times, it is desirable that the possibility of acquiring the third content C3 with a high ability value is low.

The giving means 218 may give the owner of the second content C2 after a predetermined period of time has passed since the synthesis of the second content C2, according to the number of wins in the competitive game. For example, the granting unit 218 increases the in-game ability value of the third content C3 as the number of defense game wins increases.

The providing means 218 may provide the owner of the second content C2 with a profit according to the current location of the owner during at least part of the time from the generation of the second content C2 until the elapse of a predetermined period of time. For example, the granting means 218 grants an advantageous game effect during the period when the owner of the second content C2 is located at a place arbitrarily set as his/her home while the match game is in progress. The accepting means 216 acquires the current location of the owner of the second content C2, and the granting means 218 grants benefits according to the current location based on the acquired current location information. Also, the granting means 218 may change the ability value of the player character according to the distance from the home of the owner of the second content C2 to the current location. Note that advantageous game effects are not limited to game effects during the progress of the competitive game, such as making it easier for the owner of the second content C2 to win. Benefits that are effective when a competitive game is not in progress, such as being able to refuse a competitive game (other players cannot request a competitive game), may be given. According to this aspect, for example, the closer the current location of the owner of the second content C2 is to his home, the more advantageous the game progresses.

5.1 Attachment Processing of First Content C1 FIG. 11 is an activity diagram showing an example of attachment processing of the first content C1.

First, at A101, the BC node device 10-1 (hereinafter referred to as game terminal 10-1) receives a game start operation by the first player. The game terminal 10-1 transmits a request to acquire the first content C1 (eg, login request or game result) to the game server device 20 (A202). The generating means 215 of the game server device 20 gives the first content C1 to the player (A203). Management means 214 transmits ownership information indicating the owner of first content C1 to transaction server device 40 (A204).

Transaction server device 40 generates NFT information indicating ownership of first content C1 based on the received ownership information. Transaction server device 40 also stores the generated NFT information (A205). The BC processing means 412 transmits to the BC system 100 request data requesting registration of the NFT describing the content indicated by the NFT information in the blockchain. Based on the NFT information indicated by the received request data, the BC system 100 converts the NFT indicating the ownership information of the first content C1 into transaction data (the game server device has logged in the first content C1 to the game terminal 10-1). A request is made to store in a block (ledger) as transaction information transferred to the player. The ledger is distributed and recorded by the BC storage means 111 of the plurality of BC node devices 10 (A206).

Transaction server device 40 causes game terminal 10-1 to display first content C1 related to the registered ownership information as given first content C1. Then, the game terminal 10-1 displays the first content C1 on the screen, thereby notifying that the first player has acquired the ownership of the first content C1 (A207).

As described above, the management means 214 of the game server device 20 manages the non-substitutable token in which the ownership information indicating the owner of the content C is described on the blockchain. Transaction server device 40 may display first content C1 on game terminal 10-1 at the same timing as the transmission of the request data to BC system 100, or complete registration of the NFT in the blockchain. You can go after

5.2 Transfer Processing of First Content C1 Based on Battle Result The first content C1 can be traded according to the battle result of the battle game between the players. In this section, transfer processing of the first content C1 based on the match results will be described. FIG. 12 is an activity diagram showing an example of transfer processing of the first content C1 based on the match result.

Each player who wants to acquire the first content C1 from another player can make a competition request (A301a and A301b) betting the owned first content C1. The game terminal 10 transmits a battle request to the game server device 20 via the game communication means 114 . When the competition request is received from each player, the competition means 219 matches the players betting on the first content C1 having the same attribute to execute a competition game.

In particular, the battle means 219 matches players who have the same number of the first contents C1 as compensation for the battle. For example, when a first player bets four pieces of first content C1 with the same attribute, the competition means 219 matches a player who bets four pieces of first content C1 with the same attribute as the first player. In this way, the competition means 219 matches players possessing the first content C1 with the same attribute, thereby scramble for the first content C1. The type and number of contents C to bet on can be arbitrarily selected at the time of requesting a match.

At this time, if the number of the first content C1 provided by the opponent of the first player is insufficient, the first content C1 provided as a substitute even if the attribute is not the same as the first content C1 provided by the first player. has the same attribute as the first content C1 possessed by the first player, it is possible to make up for the shortage by using this as a substitute. As described above, when the opponent does not possess the first content C1 having the attribute provided by the opponent, by providing a consideration equivalent to the difference, it is possible to compete with the opponent who possesses the desired first content C1. .

When the matching is completed, the battle means 219 executes the battle game. The fighting games executed here are, for example, defense games, fighting games, and turn-based battle systems. The transfer means 217 executes a process of transferring the ownership (NFT) of the first content C1 bet by the losing player to the player who won the match. For example, when a first player and a second player play against each other and the second player wins, the transfer means 217 transfers the first content C1 bet by the first player to the second player. Specifically, the transfer means 217 transmits to the exchange 4 the first content C1 to be traded and the request data indicating the transferor player (from the first player to the first player corresponding to the second player). send a request to transfer content C1).

Based on the received request data, the exchange 4 transfers the first content C1 using a smart contract or the like (A303). The exchange 4 includes the ID of the first content C1, the transferor ID of the first content C1 (representing the first player in the example of FIG. 12) and the transferee ID (representing the second player in the example of FIG. 12). Generate transaction information (transaction) associated with transaction-related information. This transaction information represents the change of the owner of the first content C1. The trade-related information includes information identifying the exchange 4 on which the trade was made.

In addition, the exchange 4 transmits to the BC system 100 request data requesting registration of this transaction information (transaction) in a block when the transaction is completed.

In the BC system 100, the miner who generated the block approves the transaction information (transaction) established on the exchange 4 (on the BC) and describes it in the block. In this block, a transaction group of each information such as the transfer of the content of the present invention is described, and this block (transaction group) is distributed and shared by each node, and is managed by the BC system 100 as a ledger. (A304). The BC system 100 thus registers in the blockchain a transaction indicating the transfer of ownership (NFT) of the first content C1. Exchange 4 transmits transaction information to game terminal 10-1 and game terminal 10-2. In this way, the content ownership (NFT) transfer is established at the exchange 4 or the BC system 100, and the transaction information (transaction) is stored in blocks. In other words, these transaction information (transactions) are not stored in the game server device 20 . Based on the ownership information stored in the BC system 100, the game server device 20 or the game terminal 10 displays and processes the ownership of the content C (which player has acquired which content/lost). I do. Note that the game server device 20 may be connected to the BC system 100 without going through the exchange 4 (or the game server device 20 may play the role of the exchange 4) to establish a transfer-related transaction. This transaction may then be approved by the miner and stored in a block (ledger) on the BC system 100 .

The game terminal 10-1 notifies that the first player has lost the first content C1 (A305). Also, the game terminal 10-2 notifies that the second player has acquired the first content C1 (A306). These transaction information may be transmitted at the same time as the transmission to the transaction server device 40, or after the registration of the transfer of the NFT to the blockchain is completed. Further, the transmission of the transaction information to the game terminal 10 may be performed by the transaction server device 40 .

In this way, every time the owner of the first content C1 changes according to the result of the match, the transaction information (transaction) is registered in the blockchain, and the transaction including the past owner's ownership information (transaction group) is registered in the blockchain. Accumulated as history (ledger).

5.3 Trading Process of Content C In this section, the trading process will be described as an example of transfer of the first content C1. FIG. 13 is an activity diagram showing an example of trading processing for the first content C1. FIG. 14 is a diagram showing an example of an ownership management screen. FIG. 15 is a diagram showing ownership states of the first content C1. Hereinafter, the explanation will be continued assuming that the first player sells the first content C1 to the second player.

First, the game terminal 10-1 displays an ownership management screen (see FIG. 14) for accepting an operation for managing ownership of the first content C1. On the ownership management screen, a list of the first contents C1 owned by the first player is displayed, and an operation requesting sale of the first contents C1 is accepted. The first player performs a sale request operation by pressing one of the exhibition buttons 7 of the first contents C1 owned by the first player.

At this time, the first player can set the price of the first content C1 to be put up for sale. As shown in FIG. 15, the player can check ownership status of the first content C1 by other players. In this example, the number owned by each player is displayed for each attribute of the first content C1. As a result, the first player can confirm the demand for the first content C1 to be put up for sale based on the status of ownership of the first content C1 by other players, and adjust the price.

When the game terminal 10-1 receives an operation requesting the sale of the first content C1 on the ownership management screen, the BC communication means 113 and the rights processing means 116 execute a process of requesting the sale of the first content C1. (A401).

Specifically, the game terminal 10-1 sends request data indicating ownership information of the first content C1 (NFT), a request to sell, and a price (for example, a predetermined amount of virtual currency) at the time of selling to the exchange 4. Send. The exchange 4 provides an intermediary site for conducting NFT transactions, and publishes to the intermediary site a request to sell the first content C1 indicated by the received request data and its price (A402). On the other hand, it is assumed that the game server device 20 provides a public site for participating in and progressing the game.

Another player (hereinafter referred to as the second player) or trader can access the brokerage site of the exchange 4 and send a purchase request to the NFT that is sold, or to the NFT that is not sold. can also publish a buy request. The request to sell in A301 may be made when the first player who has seen the request to buy decides to sell his or her first content C1.

Assume here that game terminal 10-2 accesses the intermediary site and accepts the second player's operation to display a list of first contents C1. At A303, the game terminal 10-2 displays a list of trading objects provided by the exchange 4 using the BC communication means 113 and the rights processing means 116. FIG. When game terminal 10-1 receives an operation to request purchase of first content C1 specified from the list by the second player, in A304, right processing unit 313 and BC communication unit 314 cause purchase of first content C1. Execute the process that requests the Specifically, the game terminal 10-1 transmits to the exchange 4 request data indicating the specified first content C1 and a request to buy.

Based on the received request data, the exchange 4 transfers the first content C1 using a smart contract or the like (A405). For example, the exchange 4 first obtains the ID of the first content C1, the transferor ID of the first content C1 (representing the first player in the example of FIG. 13), and the transferee ID (the second player in the example of FIG. 13). to generate transaction information in association with transaction-related information including The transaction-related information includes, for example, the method of transaction (transaction using virtual currency in the example of FIG. 13) and the transaction amount of the transferred first content C1. This transaction information represents the change of the owner of the first content C1.

The exchange 4 processes the payment of fees from the connected transferee's wallet to the transferor's wallet. The exchange 4 and both wallets record the history of payments. The payment method may be any method such as virtual currency, NFT, or cash as long as it is determined by the exchange 4, and may be free of charge. Also, not limited to the monetary value described above, for example, if both the transferor and the transferee agree, the physical value such as real estate or the informational value such as the right to use some NFT, etc. is the first content It may be used as the charge for C1.

In addition, the exchange 4 transmits to the BC system 100 request data requesting registration of this transaction information (transaction) in a block when the transaction is completed.

In the BC system 100, the miner who generated the block approves the transaction information (transaction) established on the exchange 4 (on the BC) and describes it in the block. By distributing and sharing this block (transaction group) in each node, it is managed by the BC system 100 as a ledger (A406). When the first content C1 is bought and sold, a transaction indicating the transfer of ownership (NFT) of the first content C1 is thus registered in the blockchain.

Exchange 4 also transmits transaction information to game terminal 10-1 and game terminal 10-2. Along with this, the game terminal 10-1 notifies the first player that the ownership of the first content C1 has been sold (A407). The game terminal 10-2 notifies that the second player has purchased ownership of the first content C1 (A408).

Thus, a player who wants to obtain the first content C1 can acquire the first content C1 without competing. Also, the first content C1 is consumed every time the second content C2 is synthesized, and if the first content C1 has an attribute, it is necessary to collect the first content C1 with the same attribute. A player who wants to sell can set a price by considering the relationship between supply and demand while checking the number of possessions of other players. The transaction information may be transmitted to game terminal 10-1 at the same time as the transmission to transaction server device 40, or after registration of the NFT transfer to the blockchain is completed. . Transaction server device 40 may also transmit transaction information to game terminal 10-2.

<Modification>
When a player buys and sells content C, the price of content C may be determined in an auction format. Specifically, the player who puts up the content C may determine the end time of the auction in advance, and the player who has made the highest bid by the end time may be the content C purchaser.

5.2 Loan Processing of Second Content C2 A player who wants to advance the competitive game advantageously lends the second content C2 to a desired player until a predetermined time has passed since the generation of the second content C2. You can have the game played on your behalf. FIG. 16 is an activity diagram showing an example of lending processing of the second content C2. The lending process of the second content C2 will be described below with reference to this activity diagram.

First, the first player, who is the owner of the second content C2 (NFT), designates a desired player to whom he wants to lend, and makes a lending request for the second content C2 (NFT). At this time, the first player may designate a period for lending the second content C2. Hereinafter, the explanation will be continued assuming that the first player designates the third player. The accepting means 216 accepts this lending request (A501).

The game communication means 114 notifies the third player to that effect (A502), and if the third player accepts it (A503), the lending means 220 responds to the lending request for a predetermined period of time from the generation of the second content C2. Until the time elapses, a process of lending the NFT of the second content C2 to a desired user is performed (A504). Accompanying this, when the NFT of the second content C2 is lent, the lent information is stored in a block (ledger) as a transaction and managed by the BC system 100 .

During the lending period, when another player makes a transfer request for the second content C2 and the acceptance means 216 accepts this (A505 and A506), the competition means 219 receives the transfer request from the other player (the second player ) and the third player to whom the second content C2 is lent (A507).

As a result of the match, if the second player wins, the second content C2 is transferred (A508), and the second player obtains it (A509). Thus, during the lending period, instead of the owner of the second content C2, the third player who received the lending of the second content C2 plays a competitive game with the challenger.

Then, the giving means 218 gives profit to the third player who has received the loan of the second content C2 according to the result of the competitive game. Also, for example, when the third player wins the battle game, the granting means 218 grants the first player's in-game currency or the first content C1 a profit to the third player. In addition, even if the second and third players lose the competitive game, the granting means 218 provides the first A profit may be given to the third player who has received the loan of the 2 contents C2. Further, the lending request may require a predetermined payment from the first player, or the first player may give the third player a profit according to the result of the competitive game.

<Modification>
The granting means 218 grants the owner of the second content C2 a profit according to the current location of the owner during at least a part of the period from the generation of the second content C2 until the elapse of a predetermined period of time. A profit may be given according to the current position of the third player who has received the loan of the content C2. For example, the imparting means 218 imparts an advantageous game effect according to the current position of the third player who has received the loan of the second content C2. note that,
The imparting means 218 is not limited to the game effect during the progress of the competitive game, such as making it easier for the third player who has received the loan of the second content C2 to win. Benefits such as refusal may be given. According to this aspect, for example, if the closer the current position of the player is to the home, the more advantageous the game effect is given, the second content C2 is presented to the third player waiting at home at the timing when the first player goes out. By lending it, it is possible to advance the battle game advantageously.

[others]
(1) The aspect of this embodiment may be a program. This program causes the computer to execute each step in the information processing system 1 .
