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

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

In recent years, it has become an urgent task to transform society into one where children can grow up healthy and where people can feel joy in giving birth and raising children. For this reason, 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, to support children and child-rearing families. There is also a need to make it the nation's top priority to encourage the healthy development and independence of children, and to support the development of parents themselves, creating a society that supports child-rearing and parenting.

In order to address 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 in youth unemployment by providing education to foster a sense of vocation from an early age and supporting career development that is linked to 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 other family members and acquire basic trust in people, a sense of ethics, and a sense of independence. However, problems have been pointed out with parents who are unable to devote enough time and mental energy to their children due to a culture that prioritizes the workplace, and parents who have extreme parenting attitudes such as indifference and neglect. When parents share the joys of raising children at home, they are also 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 has led to a loss of awareness of the importance of building a family and passing on life. People need to experience the joys of raising children through school education, local communities, and other aspects of society, and to deepen their understanding of the importance of passing on their own lives to the next generation and building 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 to shoulder the burden of child-rearing alone, and child abuse has become a serious problem. It is desirable to have effective networks of mutual support among grandparents and other relatives, as well as neighbors and other members of the local community. For this reason, there is a need to reconstruct the role of supporting the upbringing of the next generation, a role previously played by families, communities, and villages, in a way that is appropriate for modern society with the help of the community and society, and to create a system of "new child-rearing support through mutual support and solidarity" in which the entire society supports child-rearing.

As described above, in combating the declining birthrate, mutual support and cooperation in raising children is important. The inventor of the present application therefore thought that a virtual space such as a game could be used as a means to achieve mutual support and cooperation in raising children. In a virtual space, many players can easily communicate. In particular, in a virtual space, people who are physically far away can communicate with each other. This dramatically increases the number of people who can communicate. Thus, the inventor of the present application thought that by using a virtual space, it would be easier to create mutual support and cooperation in raising children. Furthermore, the inventor of the present application thought that by clarifying the roles of people who interact in a virtual space, young people, including children, would be made aware of their roles and occupations in society.

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

<Overview 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 to a fourth computer 10-4. The first computer 10-1 to the fourth computer 10-4 can communicate with each other via a communication 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 terminals, 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.

The first user US1 to the fourth user US4 each have a first account ACCT1 to a fourth account ACCT4. The group G1 includes the first account ACCT1 to the fourth account ACCT4. Furthermore, a DAO (Decentralized Autonomous Organization) including the group G1 is constructed. A governance token GTKN is associated with each of the first account ACCT1 to the fourth account ACCT4 included in the group G1. The governance token GTKN is a voting right regarding the operation of the DAO. Furthermore, a smart contract 500 is set in the group G1. The smart contract 500 records the agreements in the DAO. The smart contract 500 is recorded on the blockchain.

Next, an overview of the operation of the breeding system 1 will be described. First, the breeding target 300 is set for the 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 a 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 walking the target. 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 the virtual space.

When the third user US3 executes the task, the information of the target 300 is updated in the smart contract 500 (step S4). The information of the target 300 is the track record. The track record is the history of the execution of the task 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 of the smart contract 500. In response, the 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 storage unit 14 stores programs and data and is, for example, a combination of a read only memory (ROM), a random access memory (RAM), and a storage (for example, a flash memory or a hard disk).
The programs include, for example, the following programs:
・OS (Operating System) programs
- Program data of an application that executes information processing (e.g., a web browser or a target application described later) 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 purpose 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 to 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 (Electro Luminescence) display.

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

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

The structures of the second computer 10-2 to the fourth computer 10-4 are the same as that of the first computer 10-1, so a description thereof 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.

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 to 50d can communicate with each other via a network. The network may be the Internet or an intranet. The node computers 50a to 50d are connected to the network, for example, by wire or wirelessly. The node computers 50a to 50d communicate with each other in a peer-to-peer (P2P) manner.

The node computers 50a to 50d use blockchain technology to manage the distributed ledger. For example, the node computer 50a acquires data related to token transactions to be recorded. The node computer 50a creates a block including the acquired data and adds it to the blockchain. The node computer 50a transmits information about the added block to the node computers 50b to 50d. The node computers 50b to 50d verify the correctness of the received block. If the verification is successful, the node computers 50b to 50d add the block to the blockchain. The node computers 50a to 50d finalize the blockchain, for example, according to the number of linked blocks (number of approvals). As a result, the same distributed ledger is stored across the multiple node computers 50a to 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 Development System 1>
Next, a description will be given of the operation of the training system 1. In the training system 1, the following operations are performed.
(1) First action: The first user US1 sets the development target 300 for the group G1 using the first computer 10-1.
(2) Second action: The first user US1 sets a role and a task through 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: A third user US3 executes a task, and a token TKN is associated with a 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 out 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 Fig. 4. 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 column 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 through 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. With the above operations, the first operation is completed.

(2) Second Operation
First, the second operation will be described with reference to Fig. 5. 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 the 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, a task, and a reward for the smart contract 500. In this embodiment, the role is that the third user US3 is the person in charge of walking the subject 300. The task is that the third user US3 takes the subject 300 for a walk every morning (at least once a day between 6:00 and 10:00 a.m. for at least 10 minutes). The reward is that one point of token TKN is granted to the third user US3 when 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 columns of the smart contract 500. In 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 the group G1 by the distributed ledger system 50 in response to the operation by the first user US1 corresponding to the first account ACCT1 to which the master role is 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 the group G1 by the distributed ledger system 50 in response to the operation by the first user US1 corresponding to the first account ACCT1 to which the task setting role is 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. With the above operations, the second operation is completed.

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

In the third operation, the third user US3 executes a task, and the token TKN is associated with the third account ACCT3 corresponding to the third user US3. First, the third user US3 executes a walk (task) of the target 300 to be raised by operating the touchpad 28 of the third computer 10-3 (step S31). More specifically, the control unit 12 (virtual object control means 38) of the third computer 10-3 controls the target 300 to be raised (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 to 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 to be raised walking 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 a task. The information that the third user US3 has completed a task includes, for example, the date that the task was completed.

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

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 Fig. 7. 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 an item. Here, the token TKN is a crypto asset that can be exchanged for a virtual medium used in the development system 1. The crypto asset is, for example, a virtual currency. Furthermore, the virtual medium is a medium that can be consumed in a shop that is registered as being available for use. In other words, the virtual medium is points PT that can be used in 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. Then, the distributed ledger system 50 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. The third user US3 then performs a procedure to purchase an item on the website of the shop terminal 110 by operating the touchpad 28 of the third computer 10-3. The item is, for example, a game software or a snack. 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 information necessary for granting the item to the third user US3, associates the third user US3 who has completed the purchase procedure with the item, 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 Action
First, the fifth operation will be described with reference to Fig. 8. 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 of 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 held. In other words, the more governance token GTKN held, the more votes can be cast, or the weighting of each vote becomes higher.

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 options for the clothing color of the target 300.

The distributed ledger system 50 holds a voting event (step S52). Specifically, the distributed ledger system 50 describes the contents of the voting event in the smart contract 502 based on the information included in the voting event holding request. In this way, by steps S51 and S52, the control unit 12 (voting holding means 40) of the first computer 10-1 holds a voting event for the development target 300 in the group G1 by the distributed ledger system 50 in response to the operation of the first user US1 (a user corresponding to any of the accounts included in the group). Then, the distributed ledger system 50 transmits a voting holding notification to the first computer 10-1 to the fourth computer 10-4 (step S53). In response, each of the control units 12 of the first computer 10-1 to the fourth computer 10-4 receives the notification of step S53 via the network interface 16.

Next, the control unit 12 (voting means 42) of each of the first computer 10-1 to the fourth computer 10-4 votes based on the voting rights in response to the operation by the first user US1 to the fourth user US4 (users corresponding to the multiple accounts included in the group) (step S54). More specifically, each of the first user US1 to the fourth user US4 selects options A to C by operating the touch pad 28 of the first computer 10-1 to the fourth computer 10-4. Each of the control units 12 of the first computer 10-1 to the fourth computer 10-4 transmits voting content information including the options selected by the first user US1 to 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 tally up 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 result (step S56). Specifically, the distributed ledger system 50 changes the color of the clothing of the development target 300 to a color determined by the voting result. As described above, each of the control units 12 (development target update means 34) of the first computer 10-1 to the fourth computer 10-4 changes the information of the development target 300 of the group G1 in which the voting event was held, using the distributed ledger system 50, based on the voting result by the control unit 12 (voting means 42). With the above operations, the fifth operation is completed.

(6) Sixth Action
First, the sixth operation will be described with reference to Fig. 9. 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 300 to be raised is not a virtual object (intangible object), but an animal or plant (tangible object) in the real world. 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 the group G1 with love and responsibility. This can prevent the weakening of communication in a family or other group. When the weakening of communication in a family or other group is prevented, mutual support and cooperation are promoted. In addition, when the weakening of communication in a family or other group is prevented, the responsibility and love of raising animals and plants are nurtured at home, and joy and fun are realized. In addition, it is possible to learn how to communicate and the importance of communication not only within the family but also within groups such as friends and neighbors who raise animals and plants. As a result, the raising system 1 can contribute to measures against 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 completed, the second user US2 operates the touchpad 28 of the second computer 10-2 on behalf of the third user US3 to input that the third user US3 has completed the task. As a result, the control unit 12 of the second computer 10-2 sends a task completion notification indicating that the third account ACCT3 has completed the task to the distributed ledger system 50 via the network interface 16 (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 the 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. The information about the third user US3's task completion includes, for example, the date the task was completed.

Next, the distributed ledger system 50 updates the nurturing target information in the smart contract 500 (step S63). In this embodiment, the nurturing target information is actual results. An actual result is a task execution history by the third user US3. The distributed ledger system 50 sets the date on which the third user US3 completed the task in the actual results column of the smart contract 500 based on the information contained in the nurturing target information update request. In steps S62 and S63, when the control unit 12 (nurturing target update means 34) of the second computer 10-2 notifies that the third account ACCT3 has completed the task, it updates the information of the nurturing target 300 through 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. With the above operations, the sixth operation is completed.

(7) Seventh Action
First, the seventh operation will be described with reference to Fig. 10. 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 via 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 on the point usage contained in the usage setting information in the usage column 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. With the above operations, the seventh operation is completed.

(8) Eighth Action
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, the DAO is a community in which each of the groups G1 to G3 raises a target to be raised. Each of the groups G1 to G3 is also a community made up of DAOs made up of families, etc.

In the eighth operation, virtual objects corresponding to the targets 300, 304, and 306 of groups G1 to G3 are controlled in the same virtual space. In this DAO, the 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 the first users US1, US11, and US21 to communicate with users in the 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 operation performed by the raising target setting means 30 in the eighth operation is the same as the operation performed by the raising target setting means 30 in the first operation, so a description thereof will be omitted.

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, 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 subjects 300, 304, and 306. This completes the eighth operation.

[effect]
According to the development system 1, it is possible to suppress the weakening of communication in a group (community) such as a family. More specifically, the role setting means 32 sets the role for the development target 300 to the third account ACCT3 included in the group G1 by the distributed ledger system 50. That is, the first user US1 sets a role for the third user US3. Then, the token association means 36 associates the token TKN with the third account ACCT3 corresponding to the third user US3 who performed the task based on the role by the distributed ledger system 50. That is, the third user US3 obtains a reward by performing the task. Therefore, communication for setting the role, the task, and the reward is achieved between the first user US1 and the third user US3. As a result, according to the development system 1, it is possible to suppress the weakening of communication in a group such as a family. When the weakening of communication in a group such as a family is suppressed, support and cooperation in child-rearing are promoted. Furthermore, by preventing the weakening of communication within groups such as families, parents at home can experience the joy of raising children and can convey the joy and fun of raising children to their children. In addition, children can learn how to communicate and the importance of communication not only within families but also within groups such as daycare centers, kindergartens, schools, and neighborhood residents. As a result, the child-rearing system 1 can contribute to measures to combat the declining birthrate.

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

The virtual object control means 38 controls the development targets 300, 304, 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 be aware of and realize how a family communicates, how the development target 300 developed as a group (family) acts in the virtual space, and the achievements (achievements) in the virtual space and the evaluations from others.

The token TKN is a cryptocurrency that can be exchanged for points PT used in the training system 1. This allows the third user US3 to obtain cryptocurrency by completing a task. In other words, the third user US3 can recognize the economic significance of completing a task (reward for contribution). As a result, the third user US3 becomes more aware of his or her role, occupation, and purpose in society.

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

According to the development system 1, the weakening of communication in a group such as a family can be suppressed for the following reasons. More specifically, the voting means 42 votes based on the voting rights in response to the operation by the first user US1 to the fourth user US4 included in the group G1. Then, the development target update means 34 updates the information of the development target 300 of the group G1 in which the voting event was held, using the distributed ledger system 50, based on the voting result by the voting means 42. By holding such a voting event, the first user US1 to the fourth user US4 included in the group G1 communicate with each other about the development target 300 and about the necessity of holding the voting event. As a result, according to the development system 1, the weakening of communication in a group such as a family can be suppressed. In addition, the first user US1 to 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 voice will increase based on the degree of contribution to their own actions (number of voting rights). This further encourages the first user US1 to the fourth user US4 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 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. This limits 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 for 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 in which the 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 embodiment 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 without departing from the spirit of the present invention.

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

In the seventh operation, the purpose setting means 46 sets the purpose 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 in which the first role is set. However, the first role may be a role for setting the purpose of the token TKN associated with the third account ACCT3. In this case, the purpose setting means 46 may set the purpose 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 in which the first role is set.

The games may be action games, shooting games, role-playing games, simulation games, card games, sports games, board games, or puzzle games, etc.

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

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 a user's 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, examples of roles include feeding the animal or cleaning the animal. If the object 300 to be raised is a plant, examples of roles include watering the animal. If the object 300 to be raised is a plastic model, examples of roles include parts to be assembled, assembly, painting, etc. Roles and tasks may also correspond one-to-one.

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

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

The target 300 to be raised may be any one of the first user US1 to the fourth user US4. The target 300 to be raised may be the first user US1. The first user US1 is a father. In this case, the tasks are exercise, vaccination, medical checkups, etc. This promotes the health of the first user US1. The target 300 to be raised 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 be that the first user US1 or the second user US2 takes the third user US3 to and from lessons or cram school, or that the first user US1 or the second user US2 helps the third user US3 with studying. Helping with studying includes schedule management and marking (grading, checking) tests, etc. 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.

Each of the first user US1 to the fourth user US4 may be able to set their own goals and tasks for achieving the goals. In this case, the first user US1 to the fourth user US4 can obtain points PT when they achieve their goals by performing the tasks. For example, the goal is for the first user US1 to lose 1 kg of weight within one month, and the task is to walk 10,000 steps or more every day. The determination of whether or not the task has been performed is performed, for example, by a wearable device such as a smart watch or a smartphone. Also, the goal is to get 100 points on a test, and the task is to study for one hour or more every day. The determination of whether or not the task has been performed is performed, for example, by a tablet terminal measuring the 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 the group G1. The task may be, for example, reducing the amount of electricity used. Specifically, the task may be the operating time of an air conditioner or the set temperature of the air conditioner, the usage time of lights, etc.

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

In the fifth operation, the matters determined by the voting event are not limited to the color of the clothing of the target 300. For example, the voting event of the fifth operation may determine the development policy of the target 300 and whether or not to combine the target 300 with another target. The development policy of the target 300 is the direction in which the target 300 evolves according to the task performed by the third user US3. The evolution of the target 300 involves changes to the name, appearance, parameters, etc. of the target 300.

In the third operation, the information of the target 300 is not limited to the track record of the target 300. For example, in the third operation, changing the name, appearance, parameters, etc. of the target 300 is included in the information of the target 300 being updated.

The fact that the third user US3 has completed the task may be announced via SNS (Social Networking Service). Also, the fact that the third user US3 has acquired the token TKN or points PT by completing the task may be announced via SNS.

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

The group G1 may be a neighborhood association. In this case, the target 300 to be developed is, for example, a park, an amusement park, or the like (facility) in the real world. The task is cleaning the park. The third user US3 can exchange tokens TKN or points PT for items such as sweets. Matters related to the park may also be decided by a voting event. Matters related to the park include, for example, purchasing play equipment. The target 300 to be developed may also be a virtual space and virtual objects such as a park and play equipment (such as a city-building game or crafting game). The task may also be an action such as cleaning within the virtual space.

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

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

Note that group G1 may be a company or group (organization) in the real world. In this case, group G1 includes the accounts of multiple employees belonging to the company. The target 300 to be developed may be an animal or plant in real space, a virtual object of an animal or plant, 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. are publicized to the outside world. Furthermore, the target 300 to be developed may be a virtual space and a virtual object such as a company (a company-building game, a city-building game, a crafting game, etc.).

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

It may be possible to set in the smart contract 500 that the first user US1 or the second user US2 has 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 training target 300 may be promoted, or the amount of tokens TKN acquired may increase. In this way, the first user US1 or the second user US2 may be granted virtual currency by taking maternity leave or childcare leave, in which case, taking leave becomes the task of the first user US1 or the second user US2. Furthermore, data may be managed on the blockchain to prevent tampering with working hours and leave acquisition, and the working environment of the company may be monitored by transmitting this data to government agencies, etc. Also, by making it easier to take maternity leave or childcare leave, the problem of a declining birthrate can be solved.

In addition, the first user US1 to the fourth user US4 of group G1 may acquire more tokens TKN or points PT by performing a task with all of them. The 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 the third user US3 is executing the task, but the first user US1, the second user US2, or the fourth user US4 may also execute the task.

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

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 operates the touchpad 28 of the second computer 10-2 on behalf of the third user US3 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 that is the subject of care 300, and determine whether the third user US3 has taken a walk by determining the behavior of the third user US3 based on the location information.

The purpose setting means 46 sets the purpose 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 purpose 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.

The 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, the 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 are achieved. In addition, this embodiment can be combined with other embodiments, and other embodiments can be combined with each other as appropriate.
