The storage unit 12 stores identification information such as account information of the user of the system 10 and a wallet address of cryptocurrency, as well as various moving image data and related information described below, idea information, moving image creation request information, and the like. The communication unit 13 is a communication unit for performing wired or wireless communication with an external device according to a predetermined communication protocol. Since the client device 2 and the information processing device 3 forming the P2P network 30 have substantially the same configuration, the description thereof is omitted here.

  It should be noted that the configuration of the system 10 and the configuration of each device that constitutes the system 10 are not limited to those shown in the present embodiment. Therefore, for example, the network configuration may be changed to another configuration or the configuration of each device may be changed based on known knowledge. Further, the configurations and functions of a plurality of devices may be integrated together, the configurations and functions of a single device may be divided and distributed, or various functions may be expanded.

<1.2 System operation>
FIG. 3 is an operation flowchart of the server device 1 that provides a portal site for sharing an artificial intelligence-related video. As a premise of the flowchart, the client device 2 is accessing the server device 1 via the Internet or the like, and the initial screen of the portal site is provided to the user via the client device 2. As is clear from the figure, when the process is started, the server device 1 performs a process of accepting a mode selection signal from the client device 2 with respect to the client device 2 (S10). In the present embodiment, selectable modes are an “upload” mode for the user to upload a moving image and a “moving image playback” mode for playing back the moving image stored in the server device 1 to the user. , "A list of ideas" mode in which the moving image creator presents ideas regarding moving images and requests for requests from users, and presents an overview of the moving images that the user wants to create and accepts them. There is a "show movie creation request list" mode to recruit.

<1.2.1 “Upload” mode>
In FIG. 3, when the user selects the “upload” mode, the server device 1 shifts to a predetermined standby process of waiting for reception of a moving image and its related information (S11 NO).

  In the figure, the moving image reproduction area 82 is composed of a game operation screen and an algorithm display section 827 showing the operation state of the artificial intelligence algorithm for controlling the game operation. The game operation screen is related to a so-called block breaking game in which the slide bar 824 is operated to bounce the ball 825 to break the predetermined block group 826. On the other hand, the algorithm display unit 827 displays a schematic diagram of the relationship between the neurons and the weights of the neural network in the present embodiment, so that the degree of highlighting of each neuron changes depending on its activation state. Is shown in. At this time, the input of the neural network is associated with the position information of the slide bar, and the output is associated with the movement control command of the slide bar 824 for block breaking. Therefore, the correspondence between the activation state and input / output of each neuron of the neural network and the block breaking game at that time is confirmed on the same screen. A reproduction time display bar 821, a reproduction position display pointer 822, and a reproduction time display unit 823 are arranged at the bottom of the moving image, and the current reproduction time and the current reproduction position are displayed.

  In the figure, the detailed alert display section 83 displays the upload date and time, the moving image creator, and the total reproduction time. In the moving image explanation area 84, the explanation of the moving image entered when the moving image is uploaded is displayed.
