Using game assets managed as ownership items by each game service provider, gamers engage in various transaction activities such as acquiring, strengthening, selling, and purchasing game items within the game. can be performed.

However, currently proposed online gaming systems do not allow gamers to have full ownership of game assets. Typically, game assets are monopolized by game service providers through regulation and monitoring, and when reasons such as termination of the service occur, all items or assets are unilaterally disposed of. In addition, because the reliability of the service provider's regulation and monitoring process is not high, problems such as proprietary assets and items such as games are easily hacked or deleted due to errors in the game, etc.

Meanwhile, Block Chain is a distributed data storage technology that stores data in blocks, connects them in the form of a chain, and copies and stores them on numerous computers simultaneously. Blockchain represents a digital ledger in which transaction details that occur between users are shared and stored among network members. Rather than storing transaction records on a centralized server, transaction details are shared with all users participating in the transaction. is sent, and for each transaction, all transaction participants share information and compare it to prevent data forgery or alteration.

Therefore, recently, research has been actively conducted to safely store transaction details using blockchain in industrial fields that deal with transactions between users, such as Internet commerce and financial services.

Korean Patent Publication No. 10-2022-0010701 describes technology regarding a computer system and method for more efficiently storing, issuing, and transacting tokenized blockchain game assets managed by such smart contracts.

1 is a diagram illustrating an example of a network environment according to an embodiment. The network environment in FIG. 1 shows an example including a plurality of electronic devices 110, 120, 130, and 140, a plurality of servers 150 and 160, and a network 170. Figure 1 is an example for explaining the invention, and the number of electronic devices or servers is not limited as in Figure 1.

The plurality of electronic devices 110, 120, 130, and 140 may be mobile or fixed terminals implemented as computer devices. Therefore, hereinafter, electronic device refers to a terminal. A plurality of electronic devices (110, 120, 130, 140) include, for example, a smart phone, a mobile phone, a tablet PC, a navigation system, a computer, a laptop, a digital broadcasting terminal, and a personal digital assistant (PDA). , PMP (Portable Multimedia Player), etc. For example, the first electronic device 110 may communicate with other electronic devices 120, 130, 140 and/or servers 150, 160 through the network 170 using a wireless or wired communication method.

The communication method is not limited, and may include not only a communication method utilizing a communication network that the network 170 may include (for example, a mobile communication network, wired Internet, wireless Internet, and a broadcast network), but also short-range wireless communication between devices. For example, the network 170 may be a Personal Area Network (PAN), a Local Area Network (LAN), a Campus Area Network (CAN), a Metropolitan Area Network (MAN), a Wide Area Network (WAN), or a Broadband Network (BBN). , may include one or more arbitrary networks such as the Internet. Additionally, the network 170 may include any one or more of network topologies including a bus network, star network, ring network, mesh network, star-bus network, tree or hierarchical network, etc. Not limited.

Each of the servers 150 and 160 is a computer device or a plurality of computers that communicate with a plurality of electronic devices 110, 120, 130, 140 and a network 170 to provide commands, codes, files, content, services, etc. It can be implemented with devices.

For example, the server 160 may provide a file for installing an application to the first electronic device 110 connected through the network 170. In this case, the first electronic device 110 can install the application using a file provided from the server 160. In addition, the first electronic device 110 connects to the server 150 under the control of an operating system (OS) or at least one program (for example, a browser or the installed application), and the server 150 provides You can receive services or content that are provided. For example, when the first electronic device 110 transmits a service request message to the server 150 through the network 170 under the control of an application, the server 150 sends a code corresponding to the service request message to the first It can be transmitted to the electronic device 110, and the first electronic device 110 can provide content to the user by configuring and displaying a screen according to the code under the control of the application.

Figure 2 is a block diagram for explaining the internal configuration of an electronic device and a server in one embodiment. In FIG. 2 , the internal configuration of the first electronic device 110 as an example of one electronic device and the server 150 as an example of one server will be described. Other electronic devices 120, 130, and 140 or the server 160 may also have the same or similar internal configuration.

The first electronic device 110 and the server 150 may include memories 211 and 221, processors 212 and 222, communication modules 213 and 223, and input/output interfaces 214 and 224. The memories 211 and 221 are computer-readable recording media and may include non-permanent mass storage devices such as random access memory (RAM), read only memory (ROM), and disk drives. Additionally, the memories 211 and 221 may store an operating system or at least one program code (for example, code for an application installed and running on the first electronic device 110). These software components may be loaded from a computer-readable recording medium separate from the memories 211 and 221. Such separate computer-readable recording media may include computer-readable recording media such as floppy drives, disks, tapes, DVD/CD-ROM drives, and memory cards. In another embodiment, software components may be loaded into the memories 211 and 221 through the communication modules 213 and 223 rather than a computer-readable recording medium. For example, at least one program is installed by files provided through the network 170 by developers or a file distribution system that distributes installation files for applications (e.g., the server 160 described above) It can be loaded into the memories 211 and 221 based on the application described above.

The processors 212 and 222 may be configured to process instructions of a computer program by performing basic arithmetic, logic, and input/output operations. Commands may be provided to the processors 212 and 222 by the memories 211 and 221 or the communication modules 213 and 223. For example, the processors 212 and 222 may be configured to execute received instructions according to program codes stored in a recording device such as the memory 211 and 221.

The communication modules 213 and 223 may provide a function for the first electronic device 110 and the server 150 to communicate with each other through the network 170, and can be used to communicate with other electronic devices (for example, the second electronic device 120 )) or may provide a function for communicating with another server (for example, the server 160). For example, a request (for example, a search request) generated by the processor 212 of the first electronic device 110 according to a program code stored in a recording device such as the memory 211 is transmitted to the network under the control of the communication module 213. It can be delivered to the server 150 through 170. Conversely, control signals, commands, content, files, etc. provided under the control of the processor 222 of the server 150 pass through the communication module 223 and the network 170 to the communication module of the first electronic device 110. It can be received by the first electronic device 110 through 213. For example, control signals or commands of the server 150 received through the communication module 213 may be transmitted to the processor 212 or memory 211, and content or files may be transmitted to the first electronic device 110. It may be stored in a storage medium that may further include.

The input/output interface 214 may be a means for interfacing with the input/output device 215. For example, an input device may include a device such as a keyboard or mouse, and an output device may include a device such as a display for displaying an application's communication session. As another example, the input/output interface 214 may be a means for interfacing with a device that integrates input and output functions, such as a touch screen. As a more specific example, the processor 212 of the first electronic device 110 uses data provided by the server 150 or the second electronic device 120 when processing commands of a computer program loaded in the memory 211. The service screen or content thus constructed may be displayed on the display through the input/output interface 214. Likewise, the input/output interface 224 can output information composed using data provided by the server 150 when the processor 222 of the server 150 processes commands of a computer program loaded in the memory 221. there is.

Additionally, in other embodiments, the first electronic device 110 and the server 150 may include more components than those shown in FIG. 2 . However, there is no need to clearly show most prior art components. For example, the first electronic device 110 is implemented to include at least some of the above-described input/output devices 215 or other devices such as a transceiver, a Global Positioning System (GPS) module, a camera, various sensors, a database, etc. Additional components may be included. As a more specific example, when the first electronic device 110 is a smartphone, the smartphone generally includes an acceleration sensor, a gyro sensor, a camera, various physical buttons, a button using a touch panel, an input/output port, and a device for vibration. It can be seen that various components such as a vibrator can be implemented to be further included in the first electronic device 110.

Below, we will describe a specific embodiment of a method and system that is compatible with other NFT users in an NFT-based online game that allows NFT characters from other projects to be converted into NFT characters that can be used within an NFT-based online game. .

Figure 3 is a block diagram showing a system compatible with other NFT users in an NFT-based online game according to an embodiment. Additionally, Figure 4 is a flowchart showing a method of compatibility with other NFT users in an NFT-based online game according to an embodiment.

Referring to FIG. 3, a system compatible with other NFT users in an NFT-based online game according to one embodiment can convert NFT characters from other projects into NFT characters usable within the NFT-based online game. Here, in an NFT-based online game according to one embodiment, a system compatible with other NFT users may be the server 150 or the processor 222 of the server 150 described in FIGS. 1 and 2. Additionally, in an NFT-based online game according to one embodiment, a system compatible with other NFT users may be included in or include a blockchain platform.

The server 150 described in FIGS. 1 and 2 provides a service compatible with other NFT users in an NFT-based online game for a plurality of electronic devices 110, 120, 130, and 140 that are clients. In response to service requests through dedicated applications installed on electronic devices (110, 120, 130, 140) or through access to web/mobile sites related to the server (150), it is compatible with other NFT users in NFT-based online games. We can provide services that:

The server 150 may provide a system compatible with other NFT users in the NFT-based online game so that the server 150 can perform the method of being compatible with other NFT users in the NFT-based online game according to FIG. 4. More specifically, the processor 222 of the server 150 is a component, as shown in FIG. 3, an NFT character usage fee storage unit 310, an NFT character grade providing unit 320, and an NFT character conversion unit 330. It may include, and depending on the embodiment, it may further include at least one of an online game providing unit, a token management unit, and an interest payment unit. Depending on the embodiment, components of the processor 222 may be selectively included in or excluded from the processor 222. Additionally, depending on the embodiment, components of the processor 222 may be separated or merged to express the functions of the processor 222. For example, at least some of the components of the processor 222 may be implemented in a processor included in the user's terminal.

This processor 222 and the components of the processor 222 control the server 150 to perform the steps (S110 to S130) included in the method of being compatible with other NFT users in the NFT-based online game of FIG. You can. For example, the processor 222 and its components may be implemented to execute instructions according to the code of an operating system included in the memory 221 and the code of at least one program.

Here, the components of the processor 222 may be expressions of different functions of the processor 222 that are performed by the processor 222 according to instructions provided by the program code stored in the server 150. . For example, as a functional expression of the processor 222 that controls the server 150 according to the above-described command so that the server 150 receives a usage fee for using another NFT character in an NFT-based online game, the NFT character usage fee The storage unit 310 may be used.

Before step S110, the processor 222 can read the necessary commands from the memory 221 loaded with commands related to control of the server 150 (not shown as a separate step in the drawing). In this case, the read command may include an command for controlling the processor 222 to execute steps S110 to S130 that will be described later.

A method of being compatible with other NFT users in an NFT-based online game performed by a computer device according to an embodiment includes receiving a fee for using another NFT character in an NFT-based online game (S110), other NFT It may include a step of giving the character a grade or value that can be used in the online game (S120), and a step of converting another NFT character into an NFT character that can be used in the online game (S130).

Additionally, the step of playing an online game using the converted NFT character may be further included.

In addition, it may further include the step of the user connecting a personal electronic wallet to withdraw cash through an exchange or using the token through the user's NFT purchase.

In addition, a step of paying interest as tokens are deposited for a certain period of time may be further included.

Embodiments allow NFT projects around the world to convert their NFT shapes/designs into basic characters (e.g., egg shapes) that can be used in online games, so that online game services can be used in the same way.

For example, if you partner with the Starbucks NFT project, users with Starbucks NFTs around the world can access NFT-based online games and convert their NFTs into NFT characters that can be used in the online game, creating in-game goods. You can participate in games where you can earn tokens. For example, users who have a Starbucks NFT enter the provided portal service and obtain a Starbucks character converted into an egg shape, which is an NFT character that can be used in an online game that suits them, and use it to acquire in-game goods. You can participate in all online games where you can win games and tokens.

First, users can enjoy the game by installing the provided mobile game or accessing the web-based game. NFT characters are used in games, and NFT characters can be purchased by users using external marketplaces. Meanwhile, even if users do not purchase NFT characters, they can enjoy the game by providing basic NFT characters such as egg shapes. However, depending on the grade or value of the NFT character held by the user, there may be differences in the amount/size of in-game goods and/or tokens obtained within the game.

In step S110, the NFT character usage fee storage unit 310 may receive a fee for using another NFT character in an NFT-based online game. For example, the NFT character usage fee storage unit 310 can receive usage fees according to the level desired by the user. In addition, the NFT character usage fee storage unit 310 can receive different usage fees depending on the type, form, value, etc. of the NFT character held by the user.

In step S120, the NFT character grade provider 320 may grant a grade or value usable in an online game to another NFT character. At this time, the NFT character grade providing unit 320 may grant a grade or value that can be used within the online game to other NFT characters according to the paid usage fee, and may grant a grade or value that can be used within the online game according to the grade or value of the other NFT character granted. The proportion of in-game goods obtained may vary.

Since the design of the NFT character can be flat, 3D, and has various shapes, the design of the NFT character can be converted to fit the basic frame provided, such as an egg shape, so that it can be used in an online game to participate in the game. I can do it for you. At this time, the design of tokenomics, which determines how much and at what rate the relevant users can obtain in-game goods in online games, is important. In other words, the ratio of in-game goods acquired within the online game can be determined to match the fairness of existing NFT character users provided within the online game.

In Tokenomics, depending on how much service usage fees other NFT projects pay, the level/tier of rights granted in the game to NFT holders may vary.

For example, if an NFT project called A pays 1000 CRT as an affiliate fee, A NFT holders will be given a status similar to the NFT Rare (Tier 4) level when they enter the online game, and an NFT project called B will receive 5000 CRT. If you pay as an affiliate fee, B NFT holders can be given similar abilities to NFT Epic (Tier 2) when they play. In step S130, the NFT character conversion unit 330 can convert another NFT character into an NFT character usable within an online game.

The NFT character conversion unit 330 can convert other NFT characters to have at least one of the same shape, size, and three-dimensional unity as the NFT characters in the online game. Additionally, the NFT character conversion unit 330 can convert other 2D or 3D NFT characters to have the same 3D form as the NFT characters in the online game. Additionally, the NFT character conversion unit 330 may convert other NFT characters of various shapes to have the same 4D shape as the NFT characters in the online game.

For example, the NFT character conversion unit 330 can convert other NFT characters to have the same basic frame, such as an egg shape, as the NFT characters in the online game. In other words, the NFT character conversion unit 330 can put the user's NFT character inside a 3D egg-shaped character and convert it into an NFT character that can be used in an online game.

Depending on the embodiment, it may further include at least one of an online game providing unit, a token management unit, and an interest payment unit. Here, the online game providing unit may include an in-game goods providing unit 310, a contest participation fee payment unit 320, and a token payment unit 330.

The online game provider can play online games using converted NFT characters. This will be explained in more detail below.

The token management department can allow users to connect their personal electronic wallets and withdraw cash through the exchange. Additionally, the token management department can allow users to use tokens to purchase items, NFTs, etc. At this time, partial payment for items, etc. is also possible. For example, for a $10 item, $5 can be partially paid for as an in-app purchase and the remaining $5 can be partially paid for with a token.

Additionally, the interest payment department can pay interest by depositing tokens for a certain period of time. For example, users can use tokens to purchase NFTs such as user characters, items, and parts. They can also earn additional interest through staking for a certain period of time, and can also withdraw it as cash by selling it on an exchange. .

Below, the system and method of playing online games using converted NFT characters will be described in more detail.

Figure 5 is a block diagram showing a system for playing an online game using a converted NFT character according to an embodiment. Additionally, Figure 6 is a flowchart showing a method of playing an online game using a converted NFT character according to an embodiment.

Referring to FIG. 5, a system for playing an online game using a converted NFT character according to an embodiment acquires in-game goods through a casual game, and then uses the in-game goods as an participation fee for competitions held periodically or aperiodically. You can pay and obtain tokens that are convertible into cash depending on the results of the competition. Here, in an NFT-based online game according to one embodiment, a system compatible with other NFT users may be the server 150 or the processor 222 of the server 150 described in FIGS. 1 and 2.

The server 150 may provide a system for playing an online game using a converted NFT character so that the method of playing an online game using the converted NFT character according to FIG. 6 can be performed. More specifically, the processor 222 of the server 150 includes an in-game goods provision unit 510, a contest participation fee payment unit 520, and a token payment unit 530, as shown in FIG. 5 as a component. It can be done.

Depending on the embodiment, components of the processor 222 may be selectively included in or excluded from the processor 222. Additionally, depending on the embodiment, components of the processor 222 may be separated or merged to express the functions of the processor 222. For example, at least some of the components of the processor 222 may be implemented in a processor included in the user's terminal.

This processor 222 and the components of the processor 222 control the server 150 to perform the steps (S210 to S230) included in the method of playing an online game using the converted NFT character of FIG. 6. You can. For example, the processor 222 and its components may be implemented to execute instructions according to the code of an operating system included in the memory 221 and the code of at least one program.

A method of playing an online game using a converted NFT character according to an embodiment includes providing in-game goods to a user playing the provided online game (S210), and the in-game goods held by the user are more than a preset amount. In this case, a step (S220) of allowing participation in the competition using in-game goods as an participation fee for a specific competition hosted periodically or aperiodically in the game, and a token (Token) convertible to cash depending on the results of the game of the user participating in the competition. ) may include a step of paying (S230).

In step S210, the in-game goods providing unit 510 may provide in-game goods to users who play the provided online game. The in-game goods providing unit 510 may provide at least one or more games, for example, a plurality of games, as the user downloads a mobile game or accesses a web-based game, and may provide in-game goods to the user according to the results of the game or a specific event. there is.

For example, the in-game goods provision unit 510 may provide at least one casual game as the user downloads the mobile game and accesses the game, and may provide results in each game and/or completion of a preset quest. Depending on availability, in-game goods such as gold may be paid. Casual games are games that are provided by default in downloaded mobile games or web-based games, and may include, but are not limited to, dice games, rock-paper-scissors games, war games, fighter games, racing games, etc.

Here, the in-game goods providing unit 510 may provide in-game goods provided through online games at different rates depending on the grade or value of the NFT character held by the user. For example, the in-game goods provision unit 510 may allow a user with a high-grade (e.g., level 10) NFT character to play a game, and a user with a low-grade (e.g., level 1) NFT character to play the same game. You can acquire in-game goods at twice the rate. At this time, the in-game goods provider 510 may provide in-game goods at a preset rate through online games depending on the grade or value of the NFT character, and the in-game goods provider 510 may provide the in-game goods at a preset rate of the NFT character. In-game goods can be provided at a preset rate through online games depending on the level of range or value section.

Additionally, the in-game goods provision unit 510 may provide in-game goods provided through online games at different rates as the user mounts parts or items that match the planet of origin of the NFT character. Each NFT character can select or be given a home planet, and users can purchase parts or items matching their home planet acquired through games or events or purchased directly and install them on the NFT character. For example, users can purchase parts or items that match their planet of origin through in-game goods, tokens, cash, etc. and install them on their NFT characters. Additionally, parts or items can be acquired through gifts between users.

Additionally, the in-game goods providing unit 510 may provide in-game goods provided through online games at different rates depending on the number of NFT characters the user has. For example, a user may have multiple basic NFT characters, such as an egg-shaped character, and a user with multiple NFT characters may have fewer NFT characters even if he/she plays the game through one of the NFT characters. You can acquire in-game goods at a higher rate than other users.

In step S220, if the in-game goods held by the user are more than a preset amount, the competition participation fee payment unit 520 allows the user to participate in the competition by using the in-game goods as the participation fee for a specific competition held periodically or aperiodically in the game. It can be done. For example, if a user has accumulated 500 in-game goods, he or she can participate in the contest by paying a contest participation fee of 100. Here, a contest refers to a form of game provided online, and refers to a different type of game from the game for acquiring in-game goods described above, or the same or similar game held in a different place. At this time, the types of games provided in the competition are not limited.

The contest participation fee payment unit 520 may allow the user to participate multiple times when a contest is hosted, depending on the amount of in-game goods the user has. For example, if a user has 500 in-game goods, he or she can pay the contest participation fee of 100 five times and participate in the contest five times. Meanwhile, the maximum number of participation in each competition can be set, and the maximum number of participation in the competition can be set depending on the grade or value of the NFT character held by the user as well as in-game goods.

Additionally, the competition participation fee payment unit 520 can set the participation fee differently depending on the competition hosted in the game, allowing the user to participate in the competition according to the amount of in-game goods he or she has. For example, the contest participation fee payment unit 520 may allow participants to participate in a contest by paying an entry fee of 100 for a contest held every day, and may allow them to participate in a contest by paying an entry fee of 500 for a contest held once a week. At this time, the amount/size of tokens obtained depending on the competition participation fee may also be set differently. For example, in the case of a competition where the participation fee is 500, it can be set so that more tokens can be acquired according to the results of the game and/or the completion of the quest than in the case of the competition where the participation fee is 100.

In step S230, the token payment unit 530 may pay tokens convertible into cash according to the game results of users participating in the competition. At this time, users can connect their personal electronic wallet to receive tokens. Here, the electronic wallet is stored in association with a user-controlled cryptocurrency wallet. Wallets can have public and private keys, where the public key is the wallet's unique ID or address that the user can reveal for the purpose of participating in transactions so that tokens can be transferred to the wallet, and the private key is the wallet's unique ID or address that the player can transmit to the network. It is used by the wallet to allow the player to verify that the transaction was sent from his wallet by signing each transaction.

Meanwhile, depending on the embodiment, the token may be paid even if the user does not have a personal electronic wallet, but in order to use it, the token can be used after connecting a personal electronic wallet. For example, the token payment unit 530 temporarily gives another in-game good (e.g., diamond) instead of a token to a user who does not have an electronic wallet or according to the user's selection, and converts it to a token when connecting the electronic wallet in the future. You can.

Below, an embodiment will be described using the example of a basic casual game provided by an online game being called a playground, and a competition held periodically or aperiodically being called an arena. At this time, gold can be paid as in-game goods, and tokens can be paid as cash goods.

Figure 7 is a diagram showing an example of an NFT-based online game according to an embodiment.

Referring to Figure 7, the user collects gold while playing games in the Playground (720), and uses the gold as an entry fee for a tournament called Arena (730) held at a set time once a day. The winning person or team can obtain tokens that are convertible to cash. Here, the Arena 730 is described as being opened once a day as an example, but this is only an example and is not limited thereto. At this time, the user can participate in the game in the Playground (720) and Arena (730) using the NFT character (710) provided by default or the NFT character (710) purchased from a marketplace, etc. .

Here, Playground (720) is expressed as Playground (720) for convenience of explanation and to divide it from Arena (730), but in reality, in general, game users download existing mobile games or ,　It is a casual user experience (UX) that is the same as casual games played by accessing a web-based game. At this time, the game in Playground 720, that is, the casual game, can be played without any problem even without the user connecting an electronic wallet.

There are 7 to 10 types of casual games in Playground (720), and for each event such as playing these games and beating other users or completing a specific preset quest, an in-game called Gold is awarded. Goods can be paid.

Arena (730) is a competition that is held periodically. For example, a competition may be held once a day at a set time for one hour. Users pay the participation fee for this competition with the gold they usually earn while playing games at Playground (720).

Gold, which is used as a participation fee for Arena (730), can be obtained through game results such as playing casual games and completing daily quests, or can be purchased through payment. For example, you can purchase Gold with tokens or through in-app purchases.

Here, Gold, which is obtained through the results of casual games, is basically the higher the grade/level of the NFT character (710) (i.e., user character) held by the user, the more the game can be played on the Playground (720). You get more when you do it.

The amount of gold acquired can be increased not only by the grade of the NFT character (710), but also by equipping parts or items that match the planet from which the NFT character (710) is born, and depending on the combination. For example, the planet where the NFT character 710 is from may be divided into five planets. For example, parts can be a hat, a hand-held weapon, a cape, etc. For example, an NFT character (710) is from Earth, and if you equip a weapon with Earth attributes as a part, you will receive an additional 30% boost to the amount of gold you can acquire. If you equip a weapon as a part, there may be no boosting. Here, boosting refers to a method of increasing MMR (Matchmaking Rating) by easily winning the game with the help of an expert or cheater in a ranked match of a competitive game.

Additionally, the more a user plays with multiple NFT characters (egg-shaped characters, etc.), the more gold they can acquire. Of course, the game is played with one of the NFT characters (710), but the user gets a boost in the amount of gold earned just by holding multiple NFT characters (710) together.

The more Gold you have, the more games you can participate in in the Arena (730). For example, if a low-level user plays the game hard and collects 100 Gold, and a high-level user collects 800, then in the Arena (730) competition, a low-level user can only participate in a game with a participation fee of 100 once. If you cannot participate, high-level users can participate 8 times. Therefore, the more users with high levels participate in competitions, the more likely they are to get more tokens as prize money.

Tokens obtained as prize money from Arena (730) can be used to purchase NFTs such as user characters, items, and parts, and additional interest can be earned through staking for a certain period of time, and can be sold on exchanges for cash. Withdrawals are also possible.

However, even at this point, you can enjoy the game without connecting a crypto wallet, and such users will be temporarily given another in-game currency (e.g., diamonds), which can be converted to tokens when they connect their electronic wallet in the future.

Since the market price of this token is formed on the exchange, the size/amount of NFTs (characters, items, parts, etc.) and in-game goods, Gold, that can be purchased with it may fluctuate.

　In this way, according to embodiments, in-game goods that can be obtained in online games are used as participation fees for online game competitions held periodically or aperiodically, and by participating in the competitions to obtain tokens, which are cryptocurrency, the online game Through this, in-game assets can be realized as real assets.

Figure 8 is a diagram showing an example of a method for compatibility with other NFT users in an NFT-based online game according to an embodiment.

Referring to Figure 8, a user with an NFT character 810 provided by another NFT project accesses the NFT-based online game (or portal service provided by the online game) 820 and places the NFT character 810 online. It can be converted into an NFT character (830) that can be used in the game.

For example, the NFT character 810 can be converted to have the same basic frame, such as an egg shape, as the NFT characters in the online game. In other words, the user's NFT character 810 can be inserted inside a 3D egg-shaped character and converted into an NFT character 830 that can be used in an online game.

Accordingly, users can participate in online games using NFT characters (830) available within the online game. Users can use NFT characters (830) available within online games to acquire in-game goods as compensation through a first-round game (e.g., a game held at Playground) (840), and the user's online The ratio/amount of in-game goods acquired may be determined depending on the grade or value of the NFT character 830 available in the game. After collecting in-game goods, the user can acquire tokens convertible into cash as rewards through a 2-round game (e.g., a game held in an Arena) 850 that is hosted periodically or aperiodically.

Accordingly, users who purchase various NFTs can use their NFTs to participate in NFT-based online games and obtain tokens convertible to cash as compensation.
