In recent years, the weakening of communication within groups such as families has become a problem in the real world. Using virtual reality, such as the games mentioned above, is being considered as a method for solving this problem.

The object of the present invention is to provide a development system and system that can prevent the weakening of communication in groups such as families.

In recent years, it has become an urgent issue to transform society into one where children can grow up healthy and where people can find joy in giving birth and raising children. To this end, there is a need to create new forms of mutual support and solidarity that transcend generations and involve all citizens, including government, businesses, and local communities, in supporting children and child-rearing families. Furthermore, there is a need to make it a top priority for the nation to promote the healthy development and independence of children, and to support the development of parents themselves, thereby creating a society that supports child-rearing and parenting.

In addressing these issues, it is important for young people to become independent. It is extremely important for young people to actively consider careers, marriage, childbirth, and child-rearing as their own choices in their lives, while striving for self-actualization and participation in society, in order to become independent members of society. There is a need to reverse the trend of youth unemployment by providing education to foster a sense of vocation from an early age and supporting career development that links education and employment.

Furthermore, mutual support and cooperation in child-rearing are important. The home is a place where children form loving bonds with their parents and family, and where they acquire basic trust in people, a sense of ethics, and a sense of independence. However, problems have been pointed out, such as parents who are unable to devote enough time or mentally to their children due to a culture that prioritizes work, and parents who have extreme parenting attitudes such as indifference and neglect. When parents share the joys of raising children at home, they are able to pass on the joys and fun of child-rearing to their children.

It has been pointed out that people's desire for freedom and ease is causing them to lose awareness of the importance of starting a family and passing on life. There is a need for people to experience the joys of raising children through various social interactions, such as school education and the local community, and to deepen their understanding of the importance of passing on and nurturing their own lives to the next generation and of starting a family.

However, in recent years, the environment surrounding child-rearing has changed dramatically, with the trend toward nuclear families and changes in local communities making it difficult for families alone to shoulder the burden of child-rearing, and child abuse has become a serious problem. It is desirable for mutual support networks to function effectively among grandparents and other relatives, as well as neighbors and other members of the local community. Therefore, the function of supporting the development of the next generation, which was previously carried out by families, communities, and villages, must be rebuilt in a form appropriate to modern society with the help of local and societal forces, and a system of "child-rearing support through new mutual support and solidarity" must be created in which child-rearing is supported by society as a whole.

As described above, mutual support and cooperation in child-rearing are important in addressing the declining birthrate. The inventors therefore considered that virtual spaces, such as games, could be used as a means to achieve this. In virtual spaces, many players can easily communicate. In particular, virtual spaces allow people who are physically far apart to communicate with each other. This dramatically increases the number of people who can communicate. Therefore, the inventors considered that using virtual spaces would make it easier to foster mutual support and cooperation in child-rearing. Furthermore, the inventors considered that clarifying the roles of people interacting in virtual spaces would raise awareness of roles and occupations in society among young people, including children.

The inventors of the present application therefore propose the following system, which utilizes a virtual space similar to a game.

(Embodiment)
A breeding system 1 according to an embodiment of the present disclosure will be described with reference to the drawings.

<Outline of Development System 1>
First, the overall configuration of the training system 1 will be described with reference to the drawings.

The training system 1 shown in FIG. 1 includes a first computer 10-1 through a fourth computer 10-4. The first computer 10-1 through the fourth computer 10-4 can communicate with each other via a communications network. The network may be the Internet, an intranet, or the like.

The first computer 10-1 to the fourth computer 10-4 are information processing terminals used by the first user US1 to the fourth user US4, respectively. The first computer 10-1 to the fourth computer 10-4 are, for example, smartphones, tablet devices, home game consoles, portable game consoles, or personal computers. The first user US1 to the fourth user US4 are, for example, family members. The first user US1 is the father. The second user US2 is the mother. The third user US3 is the eldest son. The fourth user US4 is the eldest daughter.

First user US1 to fourth user US4 each have a first account ACCT1 to a fourth account ACCT4. Group G1 also includes first account ACCT1 to a fourth account ACCT4. Furthermore, a DAO (Decentralized Autonomous Organization) has been established that includes group G1. Governance tokens GTKN are associated with each of first account ACCT1 to fourth account ACCT4 included in group G1. Governance tokens GTKN are voting rights for the operation of the DAO. Furthermore, smart contract 500 has been established for group G1. Agreements within the DAO are recorded in smart contract 500. Smart contract 500 is recorded on the blockchain.

Next, we will explain the outline of the operation of the breeding system 1. First, a breeding target 300 is set for group G1 in the smart contract 500 (step S1). The breeding target 300 is, for example, a virtual object displayed in a virtual space. The virtual object is, for example, a pet such as a dog.

Next, the first computer 10-1 of the first user US1 sets a role and task for the target 300 in the smart contract 500 for the third account ACCT3 corresponding to the third user US3 (step S2). The role is the role that the third user US3 plays when interacting with the target 300. In this embodiment, the role is walker. A task is a subordinate concept of the role. A task is an action that the third user US3 actually performs on the target 300. In this embodiment, the task is "US3 takes the target 300 for a walk every morning."

The third user US3 executes the task (step S3). That is, the third user US3 takes the subject 300 for a walk. The subject 300 is a virtual object. Therefore, the third user US3 uses the third computer 10-3 to take the subject 300 for a walk in a virtual space.

When the third user US3 executes a task, information about the target 300 is updated in the smart contract 500 (step S4). The information about the target 300 is track record. Track record is the task execution history by the third user US3. When the third user US3 executes a walk of the target 300, the third computer 10-3 of the third user US3 sets the date of the walk to the track record in the smart contract 500. In response, a token TKN is granted to the third account ACCT3 corresponding to the third user US3 (step S5). The token TKN is a reward for executing the task. The token TKN may be the governance token GTKN, or a token other than the governance token GTKN.

<Structure of First Computer 10-1>
Next, the structure of the first computer 10-1 will be described with reference to the drawing. Figure 2 is a block diagram of the first computer 10-1.

As shown in FIG. 2, the first computer 10-1 includes a control unit 12, a memory unit 14, a network interface 16, a graphics processing unit 18, a display 20, an audio processing unit 22, a speaker 24, an operation unit 26, and a touchpad 28.

The memory unit 14 stores programs and data. The memory unit 14 is, for example, a combination of ROM (Read Only Memory), RAM (Random Access Memory), and storage (e.g., flash memory or a hard disk).

The programs include, for example, the following programs:
- OS (Operating System) programs - Programs for applications that execute information processing (for example, web browsers or target applications described later)

The data includes, for example, the following data:
- Databases referenced in information processing - Data obtained by executing information processing (i.e., the results of executing information processing)

The control unit 12 realizes the functions of the first computer 10-1 by executing the programs stored in the storage unit 14. The control unit 12 is, for example, at least one of the following:
・CPU (Central Processing Unit)
・GPU (Graphic Processing Unit)
・ASIC (Application Specific Integrated Circuit)
・FPGA (Field Programmable Array)

The control unit 12 includes, as functional blocks, a development target setting means 30, a role setting means 32, a development target update means 34, a token association means 36, a virtual object control means 38, a vote holding means 40, a voting means 42, a completion notification means 44, a use setting means 46, and a task setting means 48.

The network interface 16 controls communication between the first computer 10-1 and external devices. The external devices are the second computer 10-2 through the fourth computer 10-4 and the distributed ledger system 50 described below.

The graphics processing unit 18 displays an image on the display 20 based on the image data generated by the control unit 12. The display 20 is a liquid crystal display or an organic EL (electroluminescence) display.

The audio processing unit 22 outputs sound from the speaker 24 based on the audio data generated by the control unit 12.

The operation unit 26 generates an operation signal based on user operation on the touchpad 28 and outputs the operation signal to the control unit 12.

Note that the structures of the second computer 10-2 through the fourth computer 10-4 are the same as those of the first computer 10-1, so explanations will be omitted.

<Structure of Distributed Ledger System 50>
Next, the structure of the distributed ledger system 50 will be described with reference to the drawings. FIG. 3 is a block diagram of the distributed ledger system 50.

The development system 1 further includes a distributed ledger system 50. As shown in FIG. 3, the distributed ledger system 50 includes multiple node computers 50a to 50d.

The node computers 50a-50d can communicate with each other via a network. The network may be the Internet, an intranet, or the like. The node computers 50a-50d are connected to the network, for example, via wired or wireless connections. The node computers 50a-50d communicate with each other using a peer-to-peer (P2P) method.

The node computers 50a-50d manage the distributed ledger using blockchain technology. For example, the node computer 50a acquires data related to token transactions to be recorded. The node computer 50a creates a block containing the acquired data and adds it to the blockchain. The node computer 50a sends information about the added block to the node computers 50b-50d. The node computers 50b-50d verify the accuracy of the received block. If the verification is successful, the node computers 50b-50d add the block to the blockchain. The node computers 50a-50d finalize the blockchain, for example, based on the number of linked blocks (number of approvals). As a result, the same distributed ledger is stored across the multiple node computers 50a-50d that make up the distributed ledger system 50. The stored data is encrypted as appropriate.

The hardware configuration of the node computers 50a to 50d may be the same as or similar to the hardware configuration of the first computer 10-1 to the fourth computer 10-4, so a detailed description will be omitted.

<Operation of the development system 1>
Next, a description will be given of the operation of the training system 1. The training system 1 performs the following operations.
(1) First operation: The first user US1 sets the development target 300 for the group G1 using the first computer 10-1.
(2) Second operation: The first user US1 sets a role and a task using the first computer 10-1.
(3) Third action: A third user US3 executes a task, and a token TKN is associated with a third account ACCT3 corresponding to the third user US3.
(4) Fourth action: The third user US3 exchanges the token TKN for points PT and uses the points PT to acquire an item.
(5) Fifth Action: A voting event is held in group G1.
(6) Sixth action: The third user US3 executes the task, and the token TKN is associated with the third account ACCT3 corresponding to the third user US3.
(7) Seventh operation: The first user US1 sets the use of the token TKN of the third user US3 through the first computer 10-1.
(8) Eighth operation: The raising objects 300, 304, and 306 of groups G1 to G3 are controlled in the same virtual space.

When the control unit 12 of the first computer 10-1 through the fourth computer 10-4 reads the programs stored in the memory unit 14, these programs cause the first computer 10-1 through the fourth computer 10-4 to execute the first through eighth operations.

(1) First Operation First, the first operation will be described with reference to the drawings. Fig. 4 is an explanatory diagram of the first operation.

In the first operation, the first user US1 sets the development target 300 for the group G1 using the first computer 10-1. The first user US1 operates the touchpad 28 of the first computer 10-1 to set the development target 300 for the group G1. In response, the control unit 12 of the first computer 10-1 sends a development target setting request to the distributed ledger system 50 via the network interface 16 (step S11). The development target setting request includes information for setting the development target 300 for the group G1.

Next, the distributed ledger system 50 sets the development target 300 for group G1 in the smart contract 500 (step S12). Specifically, the distributed ledger system 50 sets the development target 300 in the development target field of the smart contract 500 based on the information contained in the development target setting request. Through steps S11 and S12, the control unit 12 (development target setting means 30) of the first computer 10-1 sets the development target 300 for group G1 using the distributed ledger system 50.

Next, the distributed ledger system 50 notifies the first computer 10-1 that the development target 300 has been set for group G1 (step S13). The control unit 12 of the first computer 10-1 receives the notification of step S13 via the network interface 16. This completes the first operation.

(2) Second Operation First, the second operation will be described with reference to the drawings. Fig. 5 is an explanatory diagram of the second operation.

In the second operation, the first user US1 sets roles and tasks using the first computer 10-1. A master role and a task setting role are set in the smart contract 500. The master role is a role for setting roles for accounts included in group G1. The task setting role is a role for setting tasks for accounts included in group G1. In this embodiment, the master role and task setting role are set for the first account ACCT1.

The first user US1 operates the touchpad 28 of the first computer 10-1 to set a role, task, and reward for the smart contract 500. In this embodiment, the role is for the third user US3 to be the person walking the subject 300. The task is for the third user US3 to take the subject 300 for a walk every morning (at least once a day between 6:00 AM and 10:00 AM for at least 10 minutes). The reward is for the third user US3 to be granted one token TKN point each time the third user US3 continues the task for one month. In response, the control unit 12 of the first computer 10-1 sends a role/task setting request to the distributed ledger system 50 via the network interface 16 (step S21). The role/task setting request includes information about the role, information about the task, and information about the reward.

Next, the distributed ledger system 50 sets the role, task, and reward in the smart contract 500 (step S22). Specifically, the distributed ledger system 50 sets the information included in the role/task setting request in the role, task, and reward fields of the smart contract 500. Through steps S21 and S22, the control unit 12 (role setting means 32) of the first computer 10-1 sets the role for the development target 300 to the third account ACCT3 included in group G1 using the distributed ledger system 50 in response to an operation by the first user US1 corresponding to the first account ACCT1 to which the master role has been set. Furthermore, the control unit 12 (task setting means 48) of the first computer 10-1 sets the task for the development target 300 to the third account ACCT3 included in group G1 using the distributed ledger system 50 in response to an operation by the first user US1 corresponding to the first account ACCT1 to which the task setting role has been set.

Next, the distributed ledger system 50 notifies the first computer 10-1 that the role, task, and reward have been set (step S23). The control unit 12 of the first computer 10-1 receives the notification of step S23 via the network interface 16. Note that in steps S22 and S23, notifications may also be sent to the third computer 10-3. The above operations complete the second operation.

(3) Third Operation First, the third operation will be described with reference to the drawings. Fig. 6 is an explanatory diagram of the third operation.

In the third operation, the third user US3 performs a task, and the token TKN is associated with the third account ACCT3 corresponding to the third user US3. First, the third user US3 performs a task (step S31) by operating the touchpad 28 of the third computer 10-3 to take the target 300 for a walk. More specifically, the control unit 12 (virtual object control means 38) of the third computer 10-3 controls the target 300 for a walk (virtual object) in the virtual space. Specifically, the control unit 12 of the third computer 10-3 causes the avatar of the third account ACCT3 and the target 300 for a walk in the virtual space. At this time, the display 20 displays an image of the avatar of the third account ACCT3 and the target 300 for a walk in the virtual space.

Next, the control unit 12 of the third computer 10-3 sends a development target information update request to the distributed ledger system 50 via the network interface 16. The development target information update request includes information that the third user US3 has completed the task. The information that the third user US3 has completed the task includes, for example, the date the task was completed.

Next, the distributed ledger system 50 updates the development target information in the smart contract 500 (step S33). In this embodiment, the development target information is actual results. The actual results are the task execution history of the third user US3. Based on the information contained in the development target information update request, the distributed ledger system 50 sets the date on which the third user US3 completed the task in the actual results field of the smart contract 500. In steps S32 and S33, the control unit 12 (development target update means 34) of the third computer 10-3 updates the development target 300 information in the distributed ledger system 50 when the third user US3 corresponding to the third account ACCT3 executes a role-based task.

If the third account ACCT3 corresponding to the third user US3 meets the conditions in the reward column of the smart contract 500, the distributed ledger system 50 grants the token TKN to the third user US3 (step S34). Specifically, the distributed ledger system 50 (token association means 36) associates the token TKN with the third account ACCT3 corresponding to the third user US3 who performed the task. As a result, the third user US3 obtains the token TKN. The above operations complete the third operation.

(4) Fourth Operation First, the fourth operation will be described with reference to the drawings. Fig. 7 is an explanatory diagram of the fourth operation.

In the fourth operation, the third user US3 exchanges the token TKN for points PT and uses the points PT to acquire goods. Here, the token TKN is a crypto asset that can be exchanged for virtual media used in the development system 1. The crypto asset is, for example, virtual currency. Furthermore, the virtual media is a medium that can be consumed at a shop that is registered as allowing the use of virtual media. In other words, the virtual media is points PT that can be used at the shop.

First, the third user US3 operates the touchpad 28 of the third computer 10-3 to exchange the token TKN for points PT. In response, the control unit 12 of the third computer 10-3 sends a token exchange request to the distributed ledger system 50 via the network interface 16 (step S41). The token exchange request is a request to exchange the token TKN owned by the third user US3 for points PT.

Next, the distributed ledger system 50 changes the owner of the token TKN (step S42). Specifically, the distributed ledger system 50 changes the owner of the token TKN from the third account ACCT3 corresponding to the third user US3 to the first account ACCT1 corresponding to the first user US1. The distributed ledger system 50 then adds (grants) points PT to the third account ACCT3 corresponding to the third user US3 (step S43). As a result, the third user US3 acquires points PT. The points PT may be managed, for example, by a smart contract (not shown) or by a server (not shown) for managing points PT.

Next, the third user US3 accesses the website of the shop terminal 110 by operating the touchpad 28 of the third computer 10-3. Then, the third user US3 operates the touchpad 28 of the third computer 10-3 to complete the purchase procedure for an item on the website of the shop terminal 110. The item is, for example, game software or sweets. As a result, the distributed ledger system 50 subtracts points PT from the third account ACCT3 corresponding to the third user US3. That is, the third user US3 uses points PT by operating the touchpad 28 of the third computer 10-3 (step S44). At this time, the owner of the points PT is changed from the third user US3 to the owner of the shop terminal 110.

Next, the shop terminal 110 executes a process to grant the item to the third user US3. For example, the shop terminal 110 displays to the operator 112 the information necessary to grant the item to the third user US3, associates the item with the third user US3 who has completed the purchase procedure, and executes a shipping process to grant the item to the third user US3. This allows the third user US3 to obtain the item. The above operations complete the fourth operation.

(5) Fifth Operation First, the fifth operation will be described with reference to the drawings. Fig. 8 is an explanatory diagram of the fifth operation.

In the fifth operation, a voting event is held in group G1. In the voting event for group G1, the governance token GTKN is a voting right. Furthermore, the number of votes held by the first user US1 to the fourth user US4 is determined according to the amount of governance token GTKN they hold. In other words, the more governance token GTKN they hold, the more votes they can cast, or the greater the weight of each vote.

First, the first user US1 operates the touchpad 28 of the first computer 10-1 to hold a voting event. In this embodiment, a voting event is held to determine the color of the clothing of the target 300. The following colors are prepared as options for the clothing of the target 300: A: red, B: blue, and C: yellow. Then, the control unit 12 of the first computer 10-1 sends a request to hold a voting event to the distributed ledger system 50 via the network interface 16 (step S51). The request to hold a voting event includes information for determining the color of the clothing of the target 300 and information on the color options for the clothing of the target 300.

The distributed ledger system 50 hosts a voting event (step S52). Specifically, the distributed ledger system 50 describes the content of the voting event in the smart contract 502 based on the information included in the voting event hosting request. Through steps S51 and S52, the control unit 12 (vote hosting means 40) of the first computer 10-1 hosts a voting event for the development target 300 in group G1 using the distributed ledger system 50 in response to the operation of the first user US1 (a user corresponding to one of the accounts included in the group). The distributed ledger system 50 then sends a voting hosting notification to the first computer 10-1 through the fourth computer 10-4 (step S53). In response, the control units 12 of the first computer 10-1 through the fourth computer 10-4 each receive the notification of step S53 via the network interface 16.

Next, the control units 12 (voting means 42) of the first computer 10-1 through the fourth computer 10-4 each cast a vote based on their voting rights in response to operations by the first user US1 through the fourth user US4 (users corresponding to the multiple accounts included in the group) (step S54). More specifically, the first user US1 through the fourth user US4 each select options A through C by operating the touchpads 28 of the first computer 10-1 through the fourth computer 10-4. The control units 12 of the first computer 10-1 through the fourth computer 10-4 each transmit voting content information, including the options selected by the first user US1 through the fourth user US4, to the distributed ledger system 50 via the network interface 16. In response, the distributed ledger system 50 acquires the voting content information.

Next, the distributed ledger system 50 tallyes the voting event based on the voting content information (step S55). Then, the distributed ledger system 50 changes the development target 300 based on the voting results (step S56). Specifically, the distributed ledger system 50 changes the color of the development target 300's clothing to a color determined by the voting results. As described above, the control units 12 (development target update means 34) of the first computer 10-1 through the fourth computer 10-4 each change the information of the development target 300 in group G1 where the voting event was held, using the distributed ledger system 50, based on the voting results of the control units 12 (voting means 42). This completes the fifth operation.

(6) Sixth Operation First, the sixth operation will be described with reference to the drawings. Fig. 9 is an explanatory diagram of the sixth operation.

In the sixth operation, the third user US3 executes the task, and the token TKN is associated with the third account ACCT3 corresponding to the third user US3. However, in the sixth operation, the target of care 300 is not a virtual object (intangible object) but a real-world animal or plant (tangible object). In this embodiment, the animal or plant is a dog. The first user US1 to the fourth user US4 raise the animals and plants in group G1 with love and responsibility. This prevents communication from becoming weaker within a group such as a family. Preventing communication from becoming weaker within a group such as a family promotes mutual support and cooperation. Preventing communication from becoming weaker within a group such as a family fosters the responsibility and love of raising animals and plants at home, and people experience joy and fun. Users can also learn about the importance of communication, not only within their own family, but also within groups such as friends and neighbors who also raise animals and plants. As a result, the raising system 1 can contribute to measures to combat the declining birthrate.

First, the third user US3 walks the target 300 (task) (step S61). More specifically, the third user US3 walks the dog, which is the target 300. When the dog walk is complete, the second user US2, on behalf of the third user US3, operates the touchpad 28 of the second computer 10-2 to input that the third user US3 has completed the task. This causes the control unit 12 of the second computer 10-2 to send a task completion notification to the distributed ledger system 50 via the network interface 16, indicating that the third account ACCT3 has completed the task (step S62). In this way, the control unit 12 (completion notification means 44) of the second computer 10-2 notifies the distributed ledger system 50 that the third account ACCT3 has completed the task in response to an operation by the second user US2 (the user corresponding to the account). The task completion notification includes information that the third user US3 has completed the task. Information about the task completed by the third user US3 includes, for example, the date the task was completed.

Next, the distributed ledger system 50 updates the development target information in the smart contract 500 (step S63). In this embodiment, the development target information is actual results. The actual results are the task execution history of the third user US3. Based on the information contained in the development target information update request, the distributed ledger system 50 sets the date on which the third user US3 completed the task in the actual results field of the smart contract 500. In steps S62 and S63, when the control unit 12 (development target update means 34) of the second computer 10-2 notifies that the third account ACCT3 has completed the task, the control unit 12 (development target update means 34) of the second computer 10-2 updates the information of the development target 300 in the distributed ledger system 50. The notification that the third account ACCT3 has completed the task is made by the control unit 12 (completion notification means 44) of the second computer 10-2.

If the third account ACCT3 corresponding to the third user US3 meets the conditions in the reward column of the smart contract 500, the distributed ledger system 50 grants the token TKN to the third user US3 (step S64). Specifically, the distributed ledger system 50 (token association means 36) associates the token TKN with the third account ACCT3 corresponding to the third user US3 who performed the task. As a result, the third user US3 obtains the token TKN. The above operations complete the sixth operation.

(7) Seventh Operation First, the seventh operation will be described with reference to the drawings. Fig. 10 is an explanatory diagram of the seventh operation.

In the seventh operation, the first user US1 sets the use of the points PT of the third user US3 using the first computer 10-1. A first role is set in the smart contract 504. The first role is a role for setting the use of the points PT (virtual medium) associated with the third account ACCT3. Hereinafter, the use of the points PT associated with the third account ACCT3 will be simply referred to as the point use. In this embodiment, the first role is set for the first account ACCT1 corresponding to the first user US1.

The first user US1 operates the touchpad 28 of the first computer 10-1 to set the point usage in the smart contract 500. In this embodiment, the point usage is that the third user US3 corresponding to the third account ACCT3 will use the points PT to purchase sweets. In response, the control unit 12 of the first computer 10-1 sends a usage setting request to the distributed ledger system 50 via the network interface 16 (step S71). The usage setting request includes information regarding the point usage.

Next, the distributed ledger system 50 sets the point usage in the smart contract 500 (step S72). Specifically, the distributed ledger system 50 sets the information regarding the point usage contained in the usage setting information in the usage field of the smart contract 504. Through steps S71 and S72, the control unit 12 (usage setting means 46) of the first computer 10-1 sets the usage of the points PT (virtual medium) of the third account ACCT3 (another account included in group G1) through the distributed ledger system 50 in response to the operation of the first user US1 corresponding to the first account ACCT1 to which the first role is set.

Next, the distributed ledger system 50 notifies the first computer 10-1 that the point use has been set (step S73). The control unit 12 of the first computer 10-1 receives the notification of step S73 via the network interface 16. This completes the seventh operation.

(8) Eighth Operation First, the eighth operation will be described with reference to the drawings. FIG. 11 is an explanatory diagram of the eighth operation. As shown in FIG. 11, the DAO includes groups G1 to G3. That is, this DAO is a community in which each of the groups G1 to G3 raises a target to be raised. Furthermore, each of the groups G1 to G3 is a community made up of DAOs made up of families, etc.

In the eighth operation, virtual objects corresponding to the target 300, 304, and 306 of groups G1 to G3 are controlled in the same virtual space. In this DAO, first users US1, US11, and US21 can play a game in which the target 300 raised in group G1, the target 304 raised in group G2, and the target 306 raised in group G3 are used as virtual objects. This allows each of first users US1, US11, and US21 to communicate with users in other groups.

First, the control unit 12 (raising target setting means 30) of the first computer 10-1 in group G1 sets a raising target 300 (virtual object) in group G1 using the distributed ledger system 50. The control unit 12 (raising target setting means 30) of the first computer 10-11 in group G2 sets a raising target 304 (virtual object) in group G2 using the distributed ledger system 50. The control unit 12 (raising target setting means 30) of the first computer 10-21 in group G3 sets a raising target 306 (virtual object) in group G3 using the distributed ledger system 50. Note that the operations performed by the raising target setting means 30 in the eighth operation are the same as the operations performed by the raising target setting means 30 in the first operation, and therefore will not be described here.

Next, the first user US1 of group G1 plays the game using the first computer 10-1. The first user US11 of group G2 plays the game using the first computer 10-11. The first user US21 of group G3 plays the game using the first computer 10-21. At this time, the first user US1, the first user US11, and the first user US21 play the game simultaneously in the same virtual space. Therefore, the control unit 12 (virtual object control means 38) of the first computer 10-1 of group G1, the control unit 12 (virtual object control means 38) of the first computer 10-11 of group G2, and the control unit 12 (virtual object control means 38) of the first computer 10-21 of group G3 each control the development targets 300, 304, and 306 (virtual objects) of groups G1 to G3 in the same virtual space (step S81). As a result, the displays 20 of the first computers 10-1, 10-11, and 10-21 each display an image including the objects to be raised 300, 304, and 306. This completes the eighth operation.

[effect]
The development system 1 can prevent communication from becoming diluted in groups (communities) such as families. More specifically, the role setting means 32 sets a role for the development target 300 to a third account ACCT3 included in group G1 using the distributed ledger system 50. That is, the first user US1 sets a role for the third user US3. The token association means 36 then associates the token TKN with the third account ACCT3 corresponding to the third user US3 who performed a task based on the role using the distributed ledger system 50. That is, the third user US3 receives a reward by performing the task. Therefore, communication is facilitated between the first user US1 and the third user US3 for setting roles, task execution, and rewards. As a result, the development system 1 can prevent communication from becoming diluted in groups such as families. Reducing communication from becoming diluted in groups such as families promotes mutual support and cooperation in child-rearing. Furthermore, by preventing the weakening of communication within groups such as families, parents can experience the joy of raising children at home and pass on the joy and fun of raising children to their children. Parents can also learn how to communicate within groups, such as daycare centers, kindergartens, schools, and neighborhoods, and the importance of communication, not just within families. As a result, the child-rearing system 1 can contribute to combating the declining birthrate.

Furthermore, the first user US1 assigns a role to the third user US3. The third user US3 receives a reward for completing a task. This allows the third user US3 to become aware of his or her role, occupation, and purpose in society.

The virtual object control means 38 controls the development targets 300, 304, and 306 of groups G1 to G3 in the same virtual space. This allows communication between groups G1 to G3. For example, it is possible to become aware of and experience how family members communicate, how the development target 300 developed by the group (family) behaves in the virtual space, and the achievements (achievements) and evaluations of others in the virtual space.

Tokens TKN are crypto assets that can be exchanged for points PT used in the training system 1. This allows third users US3 to obtain crypto assets by completing tasks. In other words, third users US3 can recognize the economic significance of completing tasks (reward for contributions). As a result, third users US3 become more aware of their role, occupation, and purpose in society.

Points PT are a consumable medium at shops registered as accepting points PT. This allows the third user US3 to earn points PT by completing tasks. In other words, the third user US3 can clearly recognize the economic significance of completing tasks (reward for contributions). As a result, the third user US3 becomes more aware of his or her role, occupation, and purpose in society.

The development system 1 can also prevent communication in groups such as families from becoming weaker for the following reasons. More specifically, the voting means 42 votes based on voting rights in response to operations by the first user US1 through the fourth user US4 included in the group G1. The development target update means 34 then updates the information on the development target 300 in the group G1 where the voting event was held, using the distributed ledger system 50, based on the voting results of the voting means 42. Holding such a voting event encourages the first user US1 through the fourth user US4 included in the group G1 to communicate with each other about the development target 300 and whether or not to hold the voting event. As a result, the development system 1 can prevent communication in groups such as families from becoming weaker. Furthermore, the first user US1 through the fourth user US4 included in the group G1 can hear the opinions of users in the group G1 regardless of parent-child relationships, age, gender, etc., and can be aware that their influence is increasing based on their degree of contribution to their own actions (number of voting rights). This further encourages the first user US1 to the fourth user US4 included in group G1 to perform tasks within group G1 with enthusiasm.

The use setting means 46 sets the use of the points PT of the third account ACCT3 using the distributed ledger system 50 in response to the operation of the first user US1 corresponding to the first account ACCT1 to which the first role is set. This restricts the use of the points PT associated with the third account ACCT3. As a result, the third user US3 is prevented from using the points PT for inappropriate purposes. This makes it possible to prevent, for example, minors and the elderly from getting into trouble when using the points PT (so-called parental control).

The role setting means 32 sets the role for the development target 300 for the third account ACCT3 using the distributed ledger system 50 in response to an operation by the first user US1 corresponding to the first account ACCT1 for which a master role has been set. This prevents users other than the first user US1 corresponding to the first account ACCT1 from setting or changing the role for the development target 300. As a result, the third user US3 is prevented from changing the role without the permission of the first user US1.

The task setting means 48 sets a task for the development target 300 to the third account ACCT3 using the distributed ledger system 50 in response to an operation by the first user US1 corresponding to the first account ACCT1 to which the task setting role has been set. This prevents users other than the first user US1 corresponding to the first account ACCT1 from setting or changing tasks for the development target 300. As a result, the third user US3 is prevented from changing tasks without the permission of the first user US1.

(Other embodiments)
The various control means and processing procedures described in the above embodiments are merely examples and are not intended to limit the scope of the present invention, its applications, or its uses. The various control means and processing procedures can be appropriately modified in design within the scope that does not change the gist of the present invention.

In the fourth operation, points PT were exchanged for goods (tangible objects). However, points PT may also be exchanged for intangible objects such as virtual objects or services used in virtual space. In other words, points PT (virtual medium) may be a medium that can be exchanged for the right to use content by third user US3 of third account ACCT3 using first computer 10-1 through fourth computer 10-4. Content may be, for example, game software, music, or the ability to watch videos. In other words, the right to use content may be, for example, the right to play a game for one hour or the right to watch one episode of a video such as an anime.

In the seventh operation, the use setting means 46 sets the use of the points PT of the third account ACCT3 through the distributed ledger system 50 in response to the operation of the first user US1 corresponding to the first account ACCT1 to which the first role is set. However, the first role may also be a role for setting the use of the token TKN associated with the third account ACCT3. In this case, the use setting means 46 may set the use of the token TKN of the third account ACCT3 through the distributed ledger system 50 in response to the operation of the first user US1 corresponding to the first account ACCT1 to which the first role is set.

Games include action games, shooting games, role-playing games, simulation games, card games, sports games, board games, puzzle games, etc.

The object to be raised 300 may be a virtual object (intangible object) such as an animal or plant, or an animal or plant (tangible object) in real space. The object to be raised 300 may also be a manufactured object such as a plastic model. Furthermore, the virtual object is not limited to a single completed object, but may also be a structure (as in crafting games, city-building games, or farm games) or a robot made by combining part objects.

Note that when the target 300 to be raised is a virtual object, the target 300 to be raised may be a game character. The game character may be a player character controlled based on user operation, or a non-player character controlled by a computer.

Note that roles are not limited to walking the animal. If the object 300 to be raised is an animal, roles may include feeding, cleaning, etc. If the object 300 to be raised is a plant, roles may include watering, etc. If the object 300 to be raised is a plastic model, roles may include assembling parts, assembling, painting, etc. Furthermore, roles may correspond one-to-one to tasks.

Note that if the target 300 is a virtual object, the target 300 may change when the third user US3 performs a task. A change in the target 300 may mean, for example, a change in the appearance of the target 300 or a change in the parameters of the target 300. The appearance of the target 300 includes changing from an egg to the appearance of an animal, changing from a child to an adult, changing in size or color, or changing accessories or clothing. The parameters of the target 300 include the offensive power, defensive power, etc. of the target 300.

If the target 300 is a virtual object, and the third user US3 does not perform the task, the target 300 may become ill or injured, or its condition may deteriorate, or it may even die. This allows the user to learn about raising living things and the importance of life.

The target of training 300 may be any one of the first user US1 to the fourth user US4. The target of training 300 may be the first user US1. The first user US1 is the father. In this case, the tasks include exercise, vaccinations, and health checkups. This promotes the health of the first user US1. The target of training 300 may be the third user US3. The third user US3 is the eldest son. In this case, the task is studying. This improves the grades of the third user US3. The task may also be for the first user US1 or the second user US2 to take the third user US3 to and from extracurricular activities or cram school, or for the first user US1 or the second user US2 to help the third user US3 with their studies. Helping with studies may include schedule management and marking (grading, checking) tests. Furthermore, if the third user US3 achieves the target result, points PT or tokens TKN may be awarded to the third user US3, or points PT or tokens TKN may be awarded to the first user US1 or the second user US2.

Note that each of the first user US1 to the fourth user US4 may be able to set their own goals and tasks for achieving those goals. In this case, the first user US1 to the fourth user US4 can earn points PT if they achieve their goal by completing the task. For example, the goal may be for the first user US1 to lose 1 kg within one month, and the task may be to walk 10,000 steps or more every day. Whether the task has been completed is determined, for example, by a wearable device such as a smartwatch or a smartphone. Alternatively, the goal may be to get 100 points on a test, and the task may be to study for at least one hour every day. Whether the task has been completed is determined, for example, by a tablet device measuring study time.

The target 300 to be developed may be, for example, a virtual parameter. The virtual parameter may be, for example, the amount of carbon dioxide emissions. The third user US3 may execute a task to reduce the amount of carbon dioxide emissions in group G1. The task may be, for example, reducing electricity usage. Specifically, the task may be the operating time of the air conditioner, the set temperature of the air conditioner, the usage time of the lights, etc.

If the target 300 is a virtual parameter such as power consumption or carbon dioxide emission reduction, groups G1 to G3 may compete to reduce power consumption or carbon dioxide emissions. IoT technology may be used to manage the power consumption and carbon dioxide emissions of home appliances. This can contribute to achieving carbon neutrality and thus to combating global warming. Competition between groups G1 to G3 also leads to behavior that takes ESG and SDGs into consideration. As a result, families can address and learn about environmental issues. By competing with each other and sharing results among groups G1 to G3, members of groups G1 to G3 can work together to address environmental issues.

In the fifth operation, the items decided by the voting event are not limited to the color of the clothing of the target for raising 300. For example, the voting event of the fifth operation may also decide the development policy of the target for raising 300 and whether or not to combine the target for raising 300 with another target for raising. The development policy of the target for raising 300 is the direction in which the target for raising 300 evolves, depending on the tasks performed by the third user US3. The evolution of the target for raising 300 involves changes to the name, appearance, parameters, etc. of the target for raising 300.

Note that in the third operation, the information on the development target 300 is not limited to the achievements of the development target 300. For example, in the third operation, changes to the name, appearance, parameters, etc. of the development target 300 are included in the updating of the information on the development target 300.

In addition, the fact that the third user US3 has completed the task may be announced via SNS (Social Networking Service). Furthermore, the fact that the third user US3 has acquired tokens TKN or points PT by completing the task may also be announced via SNS.

Note that the tokens TKN or points PT may be exchanged for the right of the third user US3 to play a game for a specified period of time, the right of the third user US3 to watch a video for a specified period of time, or the right to watch television for a specified period of time.

The group G1 may be a neighborhood association. In this case, the development target 300 may be, for example, a park, amusement park, or other facility in the real world. The task is to clean the park. The third user US3 can exchange tokens TKN or points PT for items such as sweets. Furthermore, matters related to the park may be decided through a voting event. An example of a matter related to the park is the purchase of play equipment. Furthermore, the development target 300 may be a virtual space and may be virtual objects such as a park or play equipment (such as a city-building game or crafting game). The task may be an action such as cleaning within the virtual space.

Note that group G1 may be a PTA. In this case, the development target 300 is, for example, a school. Tasks include guiding children or students on the way to school, security patrols, and cooperation in school events. The development target 300 may also be a virtual space and virtual objects such as a school, children, or students (such as a school-building game, a city-building game, or a crafting game). Tasks may be actions within the virtual space, such as guiding a character, security patrols, or school events.

The group G1 may be a real-world school, extracurricular class, team, etc. (group). In this case, the development target 300 is a class or team. The tasks are jobs related to class or team management, such as being on duty, librarian, or lunch attendant. The third user US3 can use tokens TKN or points PT at the school store. If the third user US3 is an excellent student, a badge may be awarded to the third user US3. The development target 300 may also be an animal or plant or a virtual object. If the extracurricular activity is a sport, tasks may be set for practice or a game, and when the third user US3 completes the task, tokens TKN, points PT, or a badge may be awarded to the third user US3. The development target 300 may also be a virtual space and a virtual object such as a school or sports team (such as a school-building game, a sports simulation game, a city-building game, or a crafting game). Tasks may be actions such as class management or team management within a virtual space, such as being on duty, librarian, or lunch attendant.

Note that group G1 may be a real-world company, organization, etc. In this case, group G1 includes the accounts of multiple employees belonging to the company. The development target 300 may be a plant or animal in real space, a virtual object of a plant or animal, or a virtual parameter such as carbon dioxide emissions. By announcing that a task has been completed via SNS, the company's culture, achievements in addressing environmental issues and contributing to society, etc. can be publicized to the outside world. Furthermore, the development target 300 may be a virtual space and a virtual object such as a company (such as a company-building game, a city-building game, or a crafting game).

The groups can be anything that forms a variety of communities, regardless of the aforementioned Group G1, such as nursing homes, apartment complexes, sports teams, stores, or designated NFT holders. By forming a DAO for each of these groups, healthy communities can be formed by managing roles, tasks, and rewards through smart contracts, and each individual can utilize their own skills to work on solving social issues and making social contributions within each community.

The smart contract 500 may also be configured to allow the first user US1 or the second user US2 to set whether they have taken maternity leave or childcare leave. When the first user US1 or the second user US2 takes maternity leave or childcare leave, the growth of the development target 300 may be promoted, or the amount of tokens TKN acquired may increase. In this way, virtual currency may be granted when the first user US1 or the second user US2 takes maternity leave or childcare leave. In this case, taking leave becomes the task of the first user US1 or the second user US2. Furthermore, data on working hours and leave taken may be managed on a blockchain to prevent tampering, and this data may be transmitted to government agencies, etc., to monitor the working environment at companies. Furthermore, making it easier to take maternity leave or childcare leave can help solve the problem of a declining birthrate.

In addition, if all of the first user US1 to the fourth user US4 in group G1 perform tasks, the first user US1 to the fourth user US4 may acquire more tokens TKN or points PT. Tasks performed by all of the first user US1 to the fourth user US4 may be, for example, volunteer activities or activities related to environmental contributions.

Note that although the third user US3 is performing the task, the first user US1, second user US2, or fourth user US4 may also perform the task.

Note that a task does not have to be a sub-concept of a role, but may be the same as a role.

Note that the master role and task setting role may be set to an account other than the first account ACCT1 corresponding to the first user US1.

In addition, before the development target 300 is set, an election event may be held to determine the development target 300.

In the sixth operation, the second user US2, on behalf of the third user US3, operates the touchpad 28 of the second computer 10-2 to input that the third user US3 has completed the task. However, the third computer 10-3 or the fourth computer 10-4 may obtain location information from a device attached to the dog or walking equipment being raised 300, and determine the behavior of the third user US3 based on the location information to determine whether the third user US3 has taken a walk.

The usage setting means 46 sets the usage of the points PT of the third account ACCT3 through the distributed ledger system 50 in response to the operation of the first user US1 corresponding to the first account ACCT1 to which the first role is set. However, the usage setting means 46 may also be able to set the upper limit of the amount of points PT that can be used for the third account ACCT3 through the distributed ledger system 50 in response to the operation of the first user US1 corresponding to the first account ACCT1 to which the first role is set.

DAO includes groups G1 to G3. However, the community including groups G1 to G3 may be a group of players participating in a game rather than a DAO. In this case, first users US1, US11, and US21 can use the characters 300, 304, and 306 that they have raised in groups G1 to G3, respectively, in the game.

Even when these other embodiments are adopted, the effects of this embodiment will be achieved. It is also possible to combine this embodiment with other embodiments, and other embodiments with each other, as appropriate.
