[0024] FIG. 1 is a diagram showing an example of a network environment in an embodiment of the present invention. The network environment of FIG. 1 shows an example including a plurality of electronic devices 110, 120, 130, 140, a plurality of servers 150, 160, and a network 170. Such a FIG. 1 is merely an example for explaining the invention, and the number of electronic devices and the number of servers are not limited as in FIG. 1. Further, the network environment of FIG. 1 is merely an example of an environment applicable to the present embodiment, and the environment applicable to the present embodiment is not limited to the network environment of FIG. 1.

[0025] The plurality of electronic devices 110, 120, 130, 140 may be fixed terminals or mobile terminals realized by computer devices. Examples of the plurality of electronic devices 110, 120, 130, 140 include smartphones, mobile phones, navigations, PCs (personal computers), notebook PCs, digital broadcast terminals, PDAs (Personal Digital Assistants), PMPs (Portable Multimedia Players), tablets, and the like. As an example, in FIG. 1, a smartphone is shown as an example of the electronic device 110. However, in the embodiment of the present invention, the electronic device 110 may mean one of various physical computer devices that substantially use a wireless or wired communication method and can communicate with other electronic devices 120, 130, 140 and / or servers 150, 160 via the network 170.

[0026] The communication method is not limited, and it may include not only a communication method that utilizes a communication network that the network 170 can include (for example, a mobile communication network, a wired Internet, a wireless Internet, a broadcast network), but also short-range wireless communication between devices. For example, the network 170 may include any one or more of networks such as a PAN (personal area network), a LAN (local area network), a CAN (campus area network), a MAN (metropolitan area network), a WAN (wide area network), a BBN (broadband network), and the Internet. Further, the network 170 may include any one or more of network topologies including a bus network, a star network, a ring network, a mesh network, a star-bus network, a tree or hierarchical network, etc., but is not limited thereto.

[0027] Each of the servers 150 and 160 may be implemented by one or more computer devices that communicate with the plurality of electronic devices 110, 120, 130, and 140 via the network 170 to provide commands, codes, files, contents, services, etc. For example, the server 150 may be a system that provides services to the plurality of electronic devices 110, 120, 130, and 140 connected via the network 170.

[0028] FIG. 2 is a block diagram showing an example of a computer device in an embodiment of the present invention. Each of the above-described plurality of electronic devices 110, 120, 130, and 140 and each of the servers 150 and 160 may be implemented by the computer device 200 shown in FIG. 2.

[0029] Such a computer device 200 may include, as shown in FIG. 2, a memory 210, a processor 220, a communication interface 230, and an input / output interface 240. The memory 210 is a computer-readable recording medium and may include a RAM (random access memory), a ROM (read only memory), and a persistent mass storage device such as a disk drive. Here, a persistent mass storage device such as a ROM or a disk drive may be included in the computer device 200 as a separate persistent recording device distinct from the memory 210. Also, an operating system and at least one program code may be recorded in the memory 210. Such software components may be loaded into the memory 210 from another computer-readable recording medium different from the memory 210. Such another computer-readable recording medium may include computer-readable recording media such as a floppy (registered trademark) drive, a disk, a tape, a DVD / CD-ROM drive, a memory card, and the like. In other embodiments, the software components may be loaded into the memory 210 through the communication interface 230 that is not a computer-readable recording medium. For example, the software components may be loaded into the memory 210 of the computer device 200 based on a computer program installed by a file received via the network 170.

[0030] The processor 220 may be configured to process instructions of a computer program by performing basic arithmetic, logic, and input / output operations. The instructions may be provided to the processor 220 by the memory 210 or the communication interface 230. For example, the processor 220 may be configured to execute instructions received according to program code recorded in a recording device such as the memory 210.

[0031] The communication interface 230 may provide a function for the computer device 200 to communicate with other devices (for example, the recording device described above) via the network 170. As an example, requests, instructions, data, files, etc. generated by the processor 220 of the computer device 200 according to the program code recorded in a recording device such as the memory 210 may be transmitted to other devices via the network 170 under the control of the communication interface 230. Conversely, signals, instructions, data, files, etc. from other devices may be received by the computer device 200 through the communication interface 230 of the computer device 200 via the network 170. Signals, instructions, data, etc. received through the communication interface 230 may be transmitted to the processor 220 and the memory 210, and files, etc. may be recorded on a recording medium (the permanent recording device described above) that the computer device 200 may further include.

[0032] The input / output interface 240 may be means for interfacing with the input / output device 250. For example, the input device may include devices such as a microphone, a keyboard, or a mouse, and the output device may include devices such as a display and a speaker. As another example, the input / output interface 240 may also be means for interfacing with a device in which functions for input and output are integrated into one, such as a touch screen. The input / output device 250 may be composed of one device with the computer device 200. For example, in the form of a smartphone, a touch screen, a microphone, a speaker, etc. may be included in the computer device 200.

[0033] Also, in other embodiments, the computer device 200 may include fewer or more components than the components in FIG. 2. However, it is not necessary to clearly show most of the conventional components in the figure. For example, the computer device 200 may be realized to include at least a part of the above-described input / output device 250, or may further include other components such as a transceiver and a database.

[0034] Figure 3 is a diagram schematically showing an example of a personal transaction system using a blockchain according to an embodiment of the present invention. The personal transaction system 300 according to this embodiment may include a transaction server 310, a blockchain network 320, a plurality of service providers 330, and a plurality of users 340. Here, each of the plurality of users 340 may be an electronic device (as an example, one of the plurality of electronic devices 110, 120, 130, and 140 described with reference to FIG. 1) substantially realized by using the computer device 200 described with reference to FIG. 2.

[0035] Each of the plurality of service servers 330 may provide a service produced and sold by a service provider. At this time, each of the plurality of users 340 may use an electronic device to access a desired service server via a network (as an example, the network 170) to receive the provision of a service.

[0036] In the service provided by each of the plurality of service servers 330, there are in-service items, and a user (as an example, one of the plurality of users 340) may obtain the items defined in the service by using the service provided to the user. The items may be provided to the user according to the user's service usage, or may be provided to the user in a form in which the user uses a purchase function in the service to purchase a specific item.

[0037] The transaction server 310 may provide a service for item transactions between users in conjunction with a plurality of service servers 330. As an example, the transaction server 310 may provide a function for item tokenization to the plurality of service servers 330. As an example, a specific service server may provide the item tokenization function provided by the transaction server 310 to a user by means of an API (Application Programming Interface) call. At this time, an API call for the item tokenization function may be made through a user interface developed based on an SDK (Software Development Kit). In this case, the user may request the transaction server 310 to tokenize a specific item of the user through the item tokenization function. As an example, the transaction server 310 may use the blockchain network 320 to mint an item and generate a token for the item (as an example, an NFT (Non-Fungible Token)).

[0038] In addition, the transaction server 310 may provide a transaction function for transactions between a plurality of users 340 of tokenized items. As an example, the transaction server 310 may provide a page on which tokenized items are registered to a plurality of users 340, and may provide a function on the page that allows the plurality of users 340 to select or purchase the tokenized items.

[0039] When a user requests the tokenization of an item, the trading server 310 may request the corresponding service server to seal the item so that the item is not used or traded on the service. Conversely, when the user's tokenized item is sold to another user and the other user requests the use of the tokenized item, the trading server 310 may request the corresponding service server to change the ownership of the sealed item and unseal it. The request for the use of the tokenized item by another user may also be made by an API call of the service server to the function provided by the trading server 310.

[0040] The trading server 310 must interact with each of the plurality of service servers 330 in order to provide the functions for the above-described user-to-user transactions. The interaction between such a plurality of service servers 330 and the trading server 310 will be described in more detail below.

[0041] Also, in FIG. 7, an example of a centralized trading server 310 is shown, but the trading server 310 may be realized by at least a part of a plurality of nodes that realize a distributed blockchain network 320.

[0042] FIG. 4 is a diagram showing an example of a personal transaction process in an embodiment of the present invention.

[0043] For the service 420 sold by the service provider 410, in-service items 430 may be defined. At this time, the creator 440 may be the same as the service provider 410 or a third party that creates items using the item creation interface provided within the service. In other words, the in-service items 430 may be created by the service provider 410 or a third party (creator 440) and defined within the service 420. When defining an item, sealable attributes of the item may be added to the item. Also, the service and the blockchain network 320 may be linked to supply pre-tokenized items. In other words, items may be provided within the service in the form of tokens, and in this case, the process of generating tokens corresponding to the items may be omitted.

[0044] At this time, user A (450) may obtain an item using the service 420. In the embodiment of FIG. 4, assume that user A (450) obtains item 1 among the in-service items 430 by using or purchasing within the service 420. At this time, the service server that provides the service 420 (for example, one of the plurality of service servers 330 in FIG. 3) may provide user A (450) with a user interface developed based on the SDK (Software Development Kit) provided by the associated transaction server 310, and user A (450) may request tokenization for item 1 through the provided user interface. In this case, the corresponding service server may seal item 1 in a sealed item storage 460. On the other hand, the API call generated by the tokenization request using the user interface may cause the transaction server 310 to mint item 1 via the blockchain network 320 and generate a token for item 1. At this time, ownership of the token may be granted to user A (450). As an example, the generated token may move to the e-wallet of user A (450).

[0045] On the one hand, user A (450) may list a token owned by himself / herself by setting trading conditions. When the trading server 310 is implemented in a centralized manner, the trading server 310 may operate a centralized exchange for selling directly listed tokens. In this case, user B (470) can purchase the tokens listed by user A (450) by using the interface of the centralized exchange operated by the trading server 310. When the trading server 310 is implemented in a decentralized manner, the trading server 310 may generate a smart contract including trading conditions and distribute it to the nodes of the blockchain network 320. In this case, user B (470) can purchase the tokens after going through the process of signing the smart contract. The purchased tokens may be transferred to the e-wallet of user B (470).

[0046] User B (470) who has purchased the tokens may request the use of the item corresponding to the tokens he / she has purchased through the user interface provided by the service server. In this case, the seal of item 1 sealed in the sealed item storage 460 may be removed, and the ownership of item 1 may be changed from user A (450) to user B (470). After that, user B (470) can use item 1 owned by himself / herself within the service.

[0047] Items subject to transactions between users may include, in addition to the form initially defined within service 420, items obtained by combining or synthesizing two or more items according to the rules allowed by service 420, items obtained by a process of further enhancing the value within the service in terms of item attributes (e.g., item enhancement in a game service), etc.

[0048] FIG. 5 is a diagram showing an example of a process of sealing an item in an embodiment of the present invention, and FIG. 6 is a diagram showing an example of a process of unsealing an item in an embodiment of the present invention. In the embodiments of FIGS. 5 and 6, it is assumed that the transaction server 310 is distributed and is realized by at least a part of the nodes of the blockchain network 320.

[0049] In the embodiment of FIG. 5, the service server 510 may receive a tokenization request from a user for the user's item using a user interface provided through the service (521). In this case, the service server 510 may reclaim the usage right of the in-service item for the item for which the user requested tokenization (522). After that, the service server 510 may request the blockchain network 320 to issue a token for the item (523). At this time, the service server 510 may transmit the item identifier (ItemID) of the item to the blockchain network 320. The blockchain network 320 may generate a token by minting for the item corresponding to the item identifier according to the request (524), and may generate a token identifier (TokenID) of the token (525). At this time, the blockchain network 320 may record the item identifier in the metadata of the token so that the owner of the item identified by the item identifier is identified by the token. Since there are a number of services, the token may be generated to further include a service identifier (ServiceID).

[0050] In the embodiment of FIG. 6, the service server 510 may receive a request from a user to use an item corresponding to a token owned by the user, using a user interface provided through the service (611). In this case, the service server 510 may confirm the information of the user's token (612) and confirm the owner of the token. When it is confirmed that the token is owned by the user, the service server 510 may transmit a request to prevent the token from being traded any further, along with the token identifier, to the blockchain network 320. After processing according to the request so that transactions for the token become impossible (613), the blockchain network 320 may extract the item identifier included in the metadata of the token and transmit it to the service server 510 (614). In this case, the service server 510 may release the seal of the item corresponding to the transmitted item identifier and grant the user the item usage right for the item (615).

[0051] FIG. 7 is a diagram showing an example of a sealing process in an embodiment of the present invention, and FIG. 8 is a diagram showing an example of an unsealing process in an embodiment of the present invention. In the embodiments of FIGS. 7 and 8, the SDK server 710 may correspond to the trading server 310 or may correspond to a part of the trading server 310. As an example, when providing a centralized exchange, the SDK server 710 may correspond to the trading server 310. On the other hand, when providing a decentralized exchange, the trading server 310 may be realized in a form including both at least a part of the nodes constituting the blockchain network 320 and the SDK server 710. At this time, a decentralized exchange may be realized by at least some of the nodes.

[0052] In the embodiment of FIG. 7, user A (450) may request sealing from the SDK server 710. Here, the sealing request may correspond to the tokenization request. As described above, user A (450) may request sealing from the SDK server 710 by making an API call using the user interface provided by the service server 510. In this case, the SDK server 710 may confirm the ownership of the item through the service server 510 according to the request and recover the item usage right. When the item usage right is recovered, the SDK server 710 may request minting for the corresponding item from the blockchain network 320. In this case, the blockchain network 320 may generate a token corresponding to the corresponding item and grant the ownership of the token to user A (450).

[0053] In the embodiment of FIG. 8, user B (470) may request unsealing from the SDK server 710. Here, the unsealing request may correspond to the item usage request. Also in this case, user B (470) may request unsealing from the SDK server 710 by making an API call using the user interface provided by the service server 510. In this case, the SDK server 710 may confirm the ownership of the token via the blockchain network 320 according to the request. When it is confirmed that the token belongs to user B (470), user B (470) may, by means of a token return signature, cause the blockchain network 320 to move the token to the recovery electronic wallet 810 for non-tradable processing of the corresponding token. After that, the SDK server 710 may request the service server 510 to restore the item usage permission. The service server 510 may restore the item usage permission (set or change the ownership of the corresponding item to user B (470)), whereby user B (470) can use the corresponding item within the service provided by the service server 510.

[0054] According to the embodiment, the token transferred to the recovery e-wallet 810 may be reused when the same item is sealed later.

[0055] FIG. 9 is a diagram showing an example of token information for trading items of a number of services in one embodiment of the present invention. The token according to this embodiment may include a service identifier (ServiceID) 910, a token identifier (TokenID) 920, ownership information (Owner) 930, and metadata (Metadata) 940.

[0056] The service identifier 910 may be used to identify which service among the plurality of services 950 provided by the plurality of service servers 330 the corresponding token is associated with the item of.

[0057] The token identifier 920 may be used to identify which token among the plurality of tokens 960 the corresponding token is.

[0058] The ownership information 930 may be used to identify who owns the corresponding token. The corresponding token may move to the e-wallet 970 of the user having the ownership, or move to the exchange for token sales.

[0059] Also, as described above, when minting an item, the item identifier transmitted from the service server 510 may be recorded in the token metadata 940.

[0060] In this way, the token can include information on which item of which service the token corresponds to and information on the owner of the token.

[0061] FIG. 10 is a diagram showing an example of a process of receiving the issuance of a service identifier from each service and using an SDK for sealing and / or unsealing in one embodiment of the present invention.

[0062] In the first process (1010), the SDK server 710 may receive input of partner information for SDK use from the administrator of the service server 510. For example, the SDK server 710 may provide a user interface to the administrator of the service server 510, and the administrator may input partner information for SDK use through the user interface.

[0063] In the second process (1020), the SDK server 710 may set an R / S (Revenue Share) ratio including the fee at the time of item transaction. As an example, the SDK server 710 may receive input of information regarding the R / S (Revenue Share) ratio including the fee at the time of item transaction through the user interface provided to the administrator of the service server 510, and set the R / S (Revenue Share) ratio.

[0064] In the third process (1030), the SDK server 710 may issue a service identifier (ServiceID) for the service server 510.

[0065] In the fourth process (1040), the SDK server 710 may issue SDK usage permission for the service server 510. In this case, the service server 510 may implement a user interface for a user to request item sealing, unsealing of tokenized items, listing of tokenized items, etc. through the SDK.

[0066] In the fifth process (1050), the SDK server 710 may receive registration of sealable items from the administrator of the service server 510.

[0067] In the sixth process (1060), the SDK server 710 may receive a sealing request from the user. The sealing request may occur through the user interface implemented by the service server 510 using the SDK and be transmitted to the SDK server 710.

[0068] Figure 11 is a flowchart showing an example of a person-to-person transaction method according to an embodiment of the present invention. The person-to-person transaction method according to this embodiment may be executed by the computer device 200 that realizes the above-described transaction server 310. At this time, the processor 220 of the computer device 200 may be realized to execute control instructions according to the code of the operating system included in the memory 210 and the code of at least one computer program. Here, the processor 220 may control the computer device 200 so that the computer device 200 executes steps 1110 to 1180 included in the method of FIG. 11 according to the control instructions provided by the code recorded in the computer device 200.

[0069] In step 1110, the computer device 200 may issue a service identifier for the first service among a plurality of services provided through different service providers. According to the embodiment, the computer device 200 may receive input of information regarding partner information and an R / S (Revenue Share) ratio including a fee at the time of item transaction from the administrator of the first service. After that, the computer device 200 may register the first service based on the input partner information and information regarding the R / S ratio, and may generate and provide a service identifier for the registered first service. Such a service identifier may be utilized to identify which service each item and token is used in a situation where a plurality of services exist. In addition, the computer device 200 may further issue the right to use an SDK (Software Development Kit) for realizing a sealing request function, a listing request function, and / or an unsealing request function to the first service.

[0070] In step 1120, the computer device 200 may provide a sealing request function for items available within the first service, an offering request function for tokens, and an unsealing request function for tokens to the first service for which a service identifier has been issued. The sealing request function may include a function for transmitting a request for sealing items available within the first service to the computer device 200. The offering request function may include a function for transmitting a request for registering a token at an exchange for trading the generated token to the computer device 200. Also, the unsealing request function may include a function for transmitting a request for unsealing a sealed item to the computer device 200.

[0071] In step 1130, the computer device 200 may receive a sealing request from the first user for an item through the sealing request function from the first service. At this time, the computer device 200 may further receive an item identifier of the item together with the sealing request. The sealing request function may include a function for transmitting a request for sealing items available within the first service to the computer device 200, whereby the first user can transmit a sealing request to the computer device 200 within the first service.

[0072] In step 1140, the computer device 200 may request sealing of the item from the first service according to the sealing request, and may generate a token including a service identifier and the ownership of the first user for the item via a blockchain network. At this time, the computer device 200 may generate a token further including the item identifier received in step 1130.

[0073] In step 1150, the computer device 200 may receive a listing request for the token of the first user from the first service through the listing request function. As described above, the listing request function may include a function for transmitting a request to register the token with an exchange for the transaction of the generated token to the computer device 200, whereby the first user can transmit a listing request to the computer device 200 within the first service.

[0074] In step 1160, the computer device 200 may process a transaction for the token according to the listing request. As described above, the computer device 200 may register the token through a centralized exchange and process the token transaction, or register the token through a decentralized exchange realized by at least some of the nodes constituting the blockchain network and process the token transaction. At this time, the decentralized exchange may process the token transaction based on the signature for the smart contract distributed to at least some of the nodes.

[0075] In step 1170, the computer device 200 may receive an unsealing request from the second user having the ownership of the token from the first service through the unsealing request function. Here, the second user may be the same user as the first user or another user who purchased the token from the first user. In other words, if a transaction for the token is concluded in step 1160 and another user purchases the token of the first user, the second user becomes another user who purchased the token. On the contrary, if the transaction for the token is not concluded in step 1160 and the ownership of the token belongs to the first user, the second user becomes the same user as the first user. The unsealing request function may include a function for transmitting a request to unseal a sealed item to the computer device 200, whereby the second user can transmit an unsealing request to the computer device 200 within the first service.

[0076] In stage 1180, the computer device 200 may collect a token from the second user's electronic wallet according to the un-escrow request, and request the first service to un-escrow the item corresponding to the token. As an example, the computer device 200 may move the token from the second user's electronic wallet to a preset collection electronic wallet, and change the token to an unusable state. Further, by un-escrowing the item corresponding to the token according to the request, the first service enables the second user to use the item within the first service.
