A video data transmission method for transmitting video data including a view of a virtual space in which a plurality of avatars are allowed to participate, the plurality of avatars each associated with one of a plurality of users including a first user, by executing computer readable instructions by one or more processors, wherein the one or more processors are either provided with or in communication with one or more servers that store user identification information for a plurality of users of the virtual space, a first server of the one or more servers storing one or more server-hosted wallets, the method comprising the steps of:
- preparing data for generating a view of a virtual space in which at least a first avatar participates, the first avatar associated with a first user;
- transmitting the data for generating the view of the virtual space to a display of a user device of the first user;
- in response to an asset acquisition request from the user device of the first user in the virtual space,
- determining if the user identification information for the first user is associated with any one of the server-hosted wallets;
- based on a determination that the user identification information for the first user is not associated with any one of the server-hosted wallets,
- generating a first wallet in association with first user identification information for the first user;
- and
- storing the first wallet as a server-hosted wallet on the first server in association with the user identification information for the first user;
- transferring, in response to storage of the first wallet on the first server, a first non-fungible asset among one or more non-fungible assets that are digital assets for use in the virtual space and tokenized as non-fungible tokens, the first non-fungible asset corresponding to the asset acquisition request, to an address of the first wallet;
- and
- causing the display of the user device of the first user to depict a representation of the first non-fungible asset for selection by the first user.
