Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[Embodiment 1]
FIG. 1 is a diagram showing an example of the network structure of the blockchain of the first embodiment.
The blockchain network structure 200 will be described with reference to FIG.
The blockchain network structure 200 includes a mining device 1, a trading device 6, and a network 300. Then, the mining device 1 and the trading device 6 are connected to each other so as to be able to communicate with each other via the network 300.
The mining device 1 and the trading device 6 are, for example, computer devices described later.
The mining device 1 and the trading device 6 can be connected to a plurality of networks, respectively.
In the example of FIG. 1, mining devices 1a, 1b, 1c, and 1d are connected as a plurality of mining devices 1. Further, as the plurality of trading devices 6, the trading devices 6a, 6b, 6c, and 6d are connected.
The network 300 is a decentralized network such as a P2P (Peer to Peer) network, and records transaction information on a blockchain.
As described above, the blockchain is a database that records transaction information in a distributed network by generating blocks containing transaction information and concatenating the generated blocks.
Since the block contains the transaction information and the correct nonce, as well as a hash value indicating the contents of the block generated immediately before, the blockchain connects the generated blocks in chronological order. , Has a data structure that is difficult to tamper with.
The correct nonce is a value obtained when a hash function is applied to the hash value of the previous block and the input value including the correct nonce and transaction information, and a hash value in which 0s equal to or more than a predetermined number are arranged is obtained.
The correct nonce is sought by mining. In proof of work, mining is the work of searching for the correct nonce by performing a hash calculation that applies a hash function to the data contained in the block while changing the nonce contained in the block.
In proof of work, the number of times the mining device or the mining pool described later executes the above hash calculation per second is called a hash rate.

FIG. 2 is a functional block diagram showing an embodiment of the mining device of the first embodiment.
The function of the mining device 1 will be described with reference to FIG.
The mining device 1 includes a control unit 10 and a storage unit 20, and is connected to a display device 8 and a sound emitting device 9.
The storage unit 20 stores the effect information 21, the threshold value information 22, the blockchain 23, and the pre-verification information 24.
The effect information 21 is information used for the effect executed by the mining device 1 during the execution of mining described below. Further, in the storage unit 20, an effect determination table (FIG. 4) for selecting the effect information is stored as, for example, a part of the effect information 21.
The threshold value information 22 is, for example, information indicating a threshold value of the success probability of mining.
The threshold information is used when the judgment effect information output by the mining device 1 is switched according to the success probability in a consensus algorithm such as Proof of Stake or Proof of Importance in which the success probability of mining changes. Information used for.
The blockchain 23 is a database that records transaction information in a decentralized network.
The pre-verification information 24 is a so-called transaction pool that stores unverified transaction information.

FIG. 3 is a diagram showing effect information included in the mining device.
The effect information 21 includes, for example, the determination effect information shown in FIG. 3, the acquired effect information, and the non-acquired effect information.
The judgment effect information includes high-expectation judgment effect information D1 having contents that make mining successful, and low-expectation judgment effect information D2 having contents that do not expect mining to succeed. Is done.
It should be noted that there may be no difference in the degree of expectation between the determination effect information D1 and the determination effect information D2. In addition, the determination effect information may include a plurality of determination effect information whose contents are partially or completely different so as not to make the user bored. In the following description, a case where the determination effect information includes two of the determination effect information D1 and the determination effect information D2 will be described as an example.
Then, instead of selecting the determination effect information D1 or the determination effect information D2 based on the success probability of mining as described later, the determination effect information D1 and the determination effect information D2 may be randomly selected.
Even if the effect performed during mining does not indicate the success probability of mining, the user can be enjoyed simply by performing the effect during mining.
The acquired effect information includes the acquired effect information A1 and the acquired effect information A2 having different contents for notifying the user that the mining has been successful. It should be noted that the acquired effect information may include a plurality of acquired effect information whose contents are partially or completely different so as not to make the user bored. In the following description, a case where the acquired effect information includes the acquired effect information A1 and the acquired effect information A2 will be described as an example.
The non-acquired effect information includes the non-acquired effect information N1 and the non-acquired effect information N2 having different contents for notifying the user that the mining has failed. It should be noted that the non-acquisition effect information may include a plurality of non-acquisition effect information whose contents are partially or completely different so as not to make the user bored. In the following description, a case where the non-acquired effect information includes two, the non-acquired effect information N1 and the non-acquired effect information N2, will be described as an example.

FIG. 4 is a diagram illustrating a process performed by the mining device using the effect information.
FIG. 4A is a diagram showing an effect determination table for determining the effect information to be output.
In a consensus algorithm such as Proof of Stake, in which the success probability of mining changes, the determination effect information output during mining execution is determined based on the table (a-1).
As an example, when the probability of successful mining is less than a predetermined threshold value, the low expectation determination effect information D1 is selected with a probability of 100%.
When the probability of successful mining is equal to or higher than a predetermined threshold value, the high-expectation determination effect information D2 is selected with a 100% probability.
By doing so, it is possible to clearly indicate to the user whether the mining currently being performed is likely to succeed or difficult to succeed during the execution of mining.
Therefore, an element of fun is added to the mining work that can be said to be monotonous, and the user's motivation to participate in mining can be increased.
When the consensus algorithm is proof of work, the determination effect information D1 and the determination effect information D2 are randomly selected and output.
The determination effect information is not limited to this, and may be three or more, and the probability of being selected may be different for each determination effect information.

Based on the table of (a-2), the acquired effect information to be output when the mining is successful is determined.
The acquired effect information includes, for example, acquired effect information A1 and acquired effect information A2, both of which are selected and output with the same probability of 50% each.
The acquired effect information is not limited to this, and may be three or more, and the probability of being selected may be different for each acquired effect information.
Based on the table of (a-3), the non-acquisition effect information output when the mining fails is determined.
The non-acquired effect information includes, for example, non-acquired effect information N1 and non-acquired effect information N2, both of which are selected and output with the same probability of 50% each.
The non-acquired effect information is not limited to two, and may be three or more, and the probability of being selected may differ for each non-acquired effect information.

The determination effect information may be selected based on the table (a-1').
Based on the table of (a-1'), when the authority acquisition probability is equal to or higher than a predetermined threshold value, the determination effect information D2 with a higher degree of expectation is higher than when the authority acquisition probability is less than the predetermined threshold value. Is easy to select.
Further, when the authority acquisition probability is less than a predetermined threshold value, the determination effect information D1 having a low expectation degree is more likely to be selected than when the authority acquisition probability is equal to or more than a predetermined threshold value.
In this case, depending on the judgment effect to be executed, it is suggested that mining is likely to succeed or difficult to succeed, but it is not clearly presented.
As a result, the user's interest in the success or failure of mining is further increased, and the enjoyment of mining work can be increased.

FIG. 4B is a diagram showing a flow of effect information output when mining is successful.
With the start of mining, either the determination effect information D1 or the determination effect information D2 is selected and output based on the authority acquisition probability, the acquisition threshold value, and the table (a-1).
When the mining is successful, either the acquired effect information A1 or the acquired effect information A2 is selected and output based on the table (a-2).
FIG. 4C is a diagram showing a flow of effect information output when mining fails.
With the start of mining, either the determination effect information D1 or the determination effect information D2 is selected and output based on the authority acquisition probability, the acquisition threshold value, and the table (a-1).
If the mining fails, either the non-acquisition effect information N1 or the non-acquisition effect information N1 is selected and output based on the table (a-3).

FIG. 5 is a diagram showing an embodiment of determination effect information.
The judgment effect information shown in FIG. 5 is information indicating that the judgment process of whether or not the authority to connect the block including the transaction information to the blockchain has been acquired is executed by using at least one of the image and the sound. is there. The image shall include moving images and videos.
The image related to the determination effect information is displayed on the display device 8 during the execution of mining.
The sound related to the determination effect information is output from the sound emitting device 9 during the execution of mining.
As shown in FIG. 5, the determination effect information is displayed by images of different modes.
The determination effect information D1 shown in FIG. 5A animates that mining is in progress by sequentially and repeatedly displaying the determination effect image D1a to the determination effect image D1d showing how the character CH is mining. indicate.
Similarly, the determination effect information D2 shown in FIG. 5B animates that mining is in progress by repeatedly displaying the determination effect image D2a to the determination effect image D2d indicating how the character CH is mining. indicate.

As described above, the determination effect information D1 can be used as the determination effect information with a low expectation, and the determination effect information D2 can be used as the determination effect information with a high expectation.
The content of the determination effect information D2 is basically the same as that of the determination effect information D1.
However, as shown in FIG. 5, the display of the determination effect information D2 is decorated to attract the user's attention as compared with the determination effect information D1, and is a display that makes the user expect that the mining is likely to succeed. It has become.
The voice of the determination effect information D2 can also be a voice that makes the user expect that the mining is more likely to succeed than the voice of the determination effect information D1.
For example, for the judgment effect information D2, the voice of the dialogue emitted by the character CH is set to "good!", And for the determination effect information D1, the voice of the dialogue emitted by the character CH is set to "difficult!".
Expectations for each judgment effect information may differ depending on not the difference in the lines of the character CH, or in addition to the difference in the BGM during mining.
For example, with respect to the determination effect information D2, bright and flashy music that arouses the user's expectations may be played during the mining execution rather than the determination effect information D1.

FIG. 6 is a diagram showing an embodiment of acquired production information.
The acquired effect information is information indicating that the authority to connect the blocks has been acquired by using at least one of an image and an sound. The image shall include moving images and videos.
As shown in FIG. 6A, in the acquisition effect information A1, the acquisition effect image A1a to the acquisition effect image A1d showing how the character CH succeeded in excavation are sequentially and repeatedly displayed to animate the success of mining. indicate.
Further, as shown in FIG. 6B, in the acquisition effect information A2, the acquisition effect image A2a to the acquisition effect image A2d showing how the character CH succeeded in excavation are sequentially and repeatedly displayed to indicate that the mining was successful. Display animation.

As for the acquired effect information, it is possible to output a voice that notifies the user of the success of mining. Further, the sound may be different between the acquired effect information A1 and the acquired effect information A2.
For example, in the acquisition effect information A1, as the dialogue of the character CH, it is possible to inform the user that the mining has been successful in an easy-to-understand manner, and it is possible to output a voice such as "I did it!" To congratulate the user.
In addition, in the acquired production information A2, as a line of the character CH, it is possible to notify the user of the success of mining in an easy-to-understand manner and output a voice such as "I will do my best next time!" To raise expectations for the next mining. it can.
Regarding the acquired production information, in addition to or in place of the character CH lines, it is possible to inform the user of the success of mining in an easy-to-understand manner, and at the same time, a bright and flashy BGM that congratulates the user and raises expectations. You may let it flow.

FIG. 7 is a diagram showing an embodiment of non-acquired production information.
The non-acquisition effect information is information indicating that the authority to connect the blocks has not been acquired by using at least one of the image and the sound. The image shall include moving images and videos.
As shown in FIG. 7A, in the non-acquisition effect information N1, mining failed by sequentially and repeatedly displaying the non-acquisition effect image N1a to the non-acquisition effect image N1c showing how the character CH failed to be excavated. Animate that.
Further, as shown in FIG. 7B, in the acquisition effect information N2, mining failed by sequentially and repeatedly displaying the non-acquisition output image N2a to the non-acquisition output image N2c indicating how the character CH failed to excavate. Animate that.

As for the non-acquisition effect information, it is possible to output a voice for notifying the user of the failure of mining. Further, the non-acquired effect information N1 and the non-acquired effect information N2 may have different sounds.
For example, in the non-acquisition effect information N1, it is possible to output a voice such as "Sorry ..." that can inform the user of the failure of mining in an easy-to-understand manner as a line of the character CH. In addition to or in place of the character CH lines, a BGM that can inform the mining failure in an easy-to-understand manner and makes you feel disappointed may be played.
On the contrary, in the non-acquisition production information N2, it is possible to output a voice such as "I will do my best next time!" As a line of the character CH to encourage expectations for the next mining.
In addition to or in place of the dialogue of the character CH, a BGM similar to the voice of the acquired production information may be played so as to be able to inform the failure of mining in an easy-to-understand manner and to promote expectations for the next mining.

The progress of the production in the first embodiment will be described in more detail below.
FIG. 8 is a diagram illustrating an example of progress of the effect when mining fails.
During the execution of mining, for example, an animation display showing how the character CH based on the low expectation determination effect information D1 is mining is performed.
The determination effect information D1 is selected based on the authority acquisition probability, the probability threshold value, and the tables (a-1) and (a-1') of FIG.
The determination effect information D1 may be randomly selected.
After that, when the mining ends in failure, the effect is switched from the effect based on the determination effect information D1 to the effect indicating that the character CH based on the non-acquired effect information N1 has failed to be excavated.
The non-acquired effect information N1 is selected based on the table of FIG. 4 (a-3).

FIG. 9 is a diagram illustrating an example of progress of the production when mining is successful.
During the execution of mining, for example, an effect showing how the character CH based on the high-expectation determination effect information D2 is mining is performed.
The determination effect information D2 is selected based on the authority acquisition probability, the probability threshold value, and the tables (a-1) and (a-1') of FIG.
The determination effect information D2 may be randomly selected.
After that, when the mining is successful, the effect is switched from the effect based on the judgment effect information D2 to the effect indicating that the character CH based on the acquired effect information A1 has been successfully excavated.

As illustrated in FIGS. 8 and 9, the effect during mining is related to the movement and dialogue of the character CH.
Therefore, the user can clearly understand that the ongoing mining has failed or succeeded only by following the contents of the production.
The user can enjoy the story itself of the production regarding whether the character CH succeeds in mining or fails in mining, which is directly related to the success or failure of mining, and as a result, the mining can be enjoyed more.
Moreover, if the judgment effect information during mining is based on the actual authority acquisition probability, the content of the effect is even more interesting.

Returning to FIG. 2, the control unit 10 of the mining device 1 will be described.
The control unit 10 includes an input unit 11, a verification unit 12, a search unit 13, a generation unit 14, a determination unit 15, a selection unit 16, an output unit 17, and an imparting unit 18.
The input unit 11 receives the input of the transaction information broadcast from the transaction device 6 via the network 300, and stores it in the storage unit 20 as the pre-verification information 24.
The verification unit 12 extracts unverified transaction information to be included in the block from the pre-verification information 24, performs signature verification, and then includes the transaction information in the block.
The search unit 13 searches for the correct nonce as a mining process.
The generation unit 14 generates a block including transaction information, a correct nonce, and a hash value of the previous block.
The determination unit 15 determines whether or not the authority to connect the blocks has been acquired, that is, whether or not the mining has been successful.
Further, the determination unit 15 determines the probability that the authority to connect the blocks is acquired when a consensus algorithm such as proof of stake that changes the success probability of mining is used for the mining process.
The determination unit 15 may determine the amount of reward when the authority to connect the blocks is acquired.

When the determination unit 15 determines whether or not the authority to connect the blocks has been acquired, the selection unit 16 selects the determination effect information based on the table of FIG.
When it is determined that the authority to connect the blocks has been acquired, the selection unit 16 selects the acquisition effect information based on the table of FIG.
Further, when it is determined that the authority to connect the blocks has not been acquired, the selection unit 16 selects the non-acquisition effect information based on the table of FIG.
The selection unit 16 may randomly select the determination effect information D1 and the determination effect information D2 when the determination unit 15 determines whether or not the authority to connect the blocks has been acquired.
Further, the selection unit 16 may randomly switch between the acquisition effect information A1 and the acquisition effect information A2 when it is determined that the authority to connect the blocks has been acquired.
When it is determined that the authority to connect the blocks has not been acquired, the selection unit 16 may randomly switch between the non-acquisition effect information N1 and the non-acquisition effect information N2 to select.
When a consensus algorithm such as proof of stake that changes the success probability of mining is used for the mining process, the selection unit 16 selects the determination effect information D1 or the determination effect information D2 based on the table of FIG.
If the success probability of mining is less than the threshold value stored in the threshold value information 22, the selection unit 16 selects the determination effect information D1. Further, the selection unit 16 selects the determination effect information D2 if the success probability of mining is equal to or greater than the threshold value stored in the threshold value information 22.
In this case, as compared with the determination effect information D1, the determination effect information D2 may be the effect information expected to acquire the authority to connect the blocks.

The granting unit 18 adds reward information indicating the reward amount determined by the determination unit 15 to the effect information selected by the selection unit 16.
The output unit 17 outputs the effect information selected by the selection unit 16 to the display device 8 and the sound emitting device 9.
The output unit 17 broadcasts the block for which the authority to connect has been acquired to another mining device 1 connected via the network 300.
When the output unit 17 is outputting the effect information selected by the selection unit 16, if other effect information is selected by the selection unit 16, the output of the output effect information is completed, and then the other. The production information of may be output. By doing so, it is possible to prevent the production from being interrupted in the middle.
The display device 8 and the sound emitting device 9 output images and sounds according to the input effect information. The display device 8 may display the reward amount when the reward information is given to the input effect information and the authority to connect the blocks is acquired according to the reward information. Further, the sound emitting device 9 notifies the user by sounding the amount of reward when the reward information is given to the input production information and the authority to connect the blocks is acquired according to the reward information. May be good.

10 and 11 are flowcharts showing an example of the processing executed by the mining apparatus of the first embodiment.
The process described below is a process executed by the control unit 10 of the mining device 1 by each of the processing units described in FIG.
FIG. 10 is a flowchart illustrating a process at the start of mining.
The process described below is a process executed by the control unit 10 of the mining device 1 by each of the processing units described in FIG. In the following description, for the sake of simplicity, the process executed by the control unit 10 of the mining device 1 will be described as the process executed by the mining device 1.
In step S101, the mining device 1 determines whether or not the determination process for determining that the right to connect the blocks has been started has been started. The mining device 1 may automatically start the determination process when mining is started. Further, the mining device 1 may start the determination process when it receives the request to start the determination process.
If it is determined that the determination process has not started (No in step S101), the mining device 1 ends the process as it is.
When it is determined that the determination process has started (Yes in step S101), the mining device 1 determines in step S102 whether or not the authority acquisition probability is equal to or greater than a predetermined acquisition threshold value.
When it is determined that the acquisition probability of the authority is equal to or higher than the predetermined acquisition threshold value (Yes in step S102), the mining device 1 selects the determination effect information D2 having a high degree of expectation in step S103. Then, in step S104, the mining device 1 starts outputting the determination effect information D2.
When it is determined in step S102 that the acquisition probability of authority is less than a predetermined acquisition threshold value (No in step S102), the mining device 1 selects the determination effect information D1 having a low expectation in step S105. Then, the mining device 1 starts outputting the determination effect information D1 in step S106.
It should be noted that what is shown in FIG. 10 is, for example, a process when a consensus algorithm such as Proof of Stake, which changes the success probability of mining, is used.
In the case of proof of work, the mining device 1 randomly selects the acquired effect information D1 and the acquired effect information D2 at the start of mining instead of the processing of steps S102 to S106, and starts output.

FIG. 11 is a flowchart illustrating processing after the result determination.
The processing described below is a processing executed by each processing unit of the control unit 10 described in FIG. 2 by the mining device 1.
In step S201, the mining device 1 determines whether or not it has acquired the authority to connect the blocks.
When it is determined that the authority has been acquired (Yes in step S201), the mining device 1 determines in step S202 whether or not the determination effect information is being output.
When it is determined that the determination effect information is being output (Yes in step S202), the mining device 1 ends the output of the determination effect information in step S203, and selects the acquired effect information in step S204.
Then, in step S205, the mining device 1 starts outputting the acquired effect information selected in step S204.
The mining device 1 may end the effect in the middle of the mining process, instead of outputting the determination effect information during the entire period. Therefore, when it is determined in step S202 that the determination effect information is not being output (No in step S202), the mining device 1 selects the acquisition effect information in step S204 and outputs the acquisition effect information in step S205. Start.

If it is determined in step S201 that the authority to connect the blocks has not been acquired (No in step S201), the mining device 1 determines in step S206 whether or not the acquisition failure of the authority to connect the blocks has been determined. ..
The mining device 1 determines, for example, that when it receives a block to be connected to the blockchain next time from another mining device, the authority to connect the blocks has not been acquired. The mining device 1 may determine, for example, that the authority to connect the blocks has not been acquired when the correct nonce cannot be found for a predetermined time.
Therefore, if it is determined that the block has not yet been received from another mining device and the failure to acquire the authority has not yet been determined (No in step S206), the mining device 1 ends the process as it is.
When a block is received from another mining device 1 and it is determined that the acquisition of the authority to connect the block has failed (Yes in step S206), is the mining device 1 currently outputting the determination effect information in step S207? Judge whether or not.
When it is determined that the determination effect information is being output (Yes in step S207), the mining device 1 ends the output of the determination effect information in step S208, and selects the non-acquired effect information in step S209.
Then, in step S210, the mining device 1 starts outputting the non-acquisition effect information selected in step S209.
When it is determined in step S207 that the determination effect information is not being output (No in step S207), the mining device 1 selects the non-acquisition effect information in step S209 and outputs the non-acquisition effect information in step S210. Start.
After Yes in step S202, the processes of step S203 and step S204 may be executed in no particular order. Further, after Yes in step S207, the processes of step S208 and step S209 may be executed in no particular order.
As described above, the mining device 1 outputs an effect using at least one of the image and the sound when the mining process is being executed, so that the user can feel the fun.
