Description

Metaverse service apparatus with blockchain technology and driving method thereof {Metaverse Service Apparatus with Blockchain Technology and Driving Method Thereof}

The present invention relates to a metaverse service device to which blockchain technology is applied and a method for operating the device, and more specifically, to a metaverse service device to which blockchain technology is applied, and a method for operating the device, which implements the NFT (Non-Fungible Token) concept in a metaverse transaction system, which stores, in a metaverse transaction system that integrates blockchain technology, not the data of a virtual product for transaction itself but the target data (e.g., copy data, etc.) and the ownership as independent data implemented by blockchain so that forgery and alteration are impossible and can be permanently preserved.

A transparent economic system can be created in a blockchain-based metaverse. This is because ownership of virtual world assets can be proven through blockchain technology. When virtual world assets are sold to other users, the history is recorded and can be verified by everyone. Users around the world can trade directly with each other in a virtual world marketplace without intermediaries, so there are no intermediary fees and an economic system is created based on trust. Existing products and assets or newly created virtual world assets are valued according to their scarcity. The space where this scarcity shines the most is the metaverse.

Non-fungible tokens (NFTs) that have recently been gaining attention are proving their value due to their scarcity. Blockchain and NFTs are the core of supporting the economic activities of the metaverse. Blockchain, which makes it impossible to falsify data, brings trust in the virtual world where avatars and 3D characters operate anonymously, and items and various assets created as NFTs can be valued in real terms.

However, asset management in the metaverse, especially rights claims and ownership verification, are difficult to resolve with the concepts of conventional commercial transactions and personal transactions. This comes from the limitations of objects in virtual reality (hereinafter referred to as “virtual goods”), which cannot be independently and uniquely identified as data themselves, as the replicated digital data and the original data are completely identical data.

NFTs are not perfect. For example, not all data and works that have appeared on NFT exchanges so far have been traded through fair procedures. For example, it is possible for a third party to issue an NFT for a work that someone has created without notifying the original creator and then register and trade it on an exchange. In other words, there is a possibility that the ownership of all data for which an NFT is created may conflict with the original creator's copyright, which could lead to legal issues.

The primary goal of the metaverse to be implemented is to establish a platform service for fair transactions between sellers and original creators (hereinafter referred to as "corporate customers") and consumer customers. In order to minimize the above problems, corporate customers must notify that blockchain registration is a prerequisite for all virtual products they wish to register in the metaverse, and manage it so that consumer customers' rights to the products are not violated, so that the above problems do not occur.

In addition, NFTs do not contain the original data for virtual goods, and only the address for accessing the data and information about the file are recorded. The original data is uploaded to a specific server connected to the network, so it can be easily deleted or modified at any time. In other words, it is impossible to protect the data itself to claim ownership.

Of course, decentralization allows for the use of grid computing technology, and the introduction of blockchain technology, which enhances security as the consumer customer base is secured, is attractive. Therefore, the need to introduce and develop a hybrid service structure that mixes blockchain technology with the existing traditional online commerce service structure is being raised.

Korean Patent Publication No. 10-2013-0131179 (2013.12.03) Korean Patent Publication No. 10-2018-0114198 (October 17, 2018) Korean Patent Publication No. 10-2021-0086035 (2021.07.08) Korean Patent Publication No. 10-2021-0063284 (2021.06.01) Korean Patent Publication No. 10-2322511 (2021.11.01)

The purpose of the embodiment of the present invention is to provide a metaverse service device and an operating method thereof that implements the NFT concept in a metaverse transaction system, which stores the target data and ownership, not the data of a virtual product for transaction, in an independent data form implemented in a blockchain, so that forgery and tampering are impossible and can be permanently preserved in a state where they cannot be altered, in a transaction system on a metaverse that integrates blockchain technology.

A metaverse service device to which blockchain technology is applied according to an embodiment of the present invention includes a communication interface unit that provides a metaverse service screen for selling virtual goods in response to a service request from a user terminal device, and a control unit that creates copy data for original data of a virtual good when a user of the user terminal device purchases any virtual good on the provided metaverse service screen, and creates address information and contract information on ownership linked to the copy data in the form of an NFT (Non-Funible Token) and stores and manages the same in a node forming a blockchain.

The above control unit may not perform the proof of ownership for the physical product to which delivery has been made if there is a request for physical delivery of the virtual product from the user.

The above control unit can generate address information, file system information, and transaction information that can access the original data of the image related to the virtual product as the link information in the form of the NFT.

The above control unit generates copy data and a unique key related to the virtual product when it is created in the form of the NFT and manages them by matching them with the original data, and can access the copy data through the address information when proving the user's ownership.

The above control unit can recover the damaged copy data using the original data when it is determined that the copy data has been damaged.

In addition, a method for operating a metaverse service device to which blockchain technology is applied according to an embodiment of the present invention includes a step of providing, by a communication interface unit, a metaverse service screen for selling virtual goods in response to a service request from a user terminal device, and a step of creating, by a control unit, a copy data of original data of a virtual good when a user of the user terminal device purchases any virtual good on the provided metaverse service screen, and creating address information and contract information on ownership linked to the copy data in the form of an NFT and storing and managing the same in a node forming a blockchain.

The above storage and management step may not perform the proof of ownership for the physical product to which delivery has been made if there is a request for physical delivery of the virtual product from the user.

The above storage and management step can generate address information, file system information, and transaction information that can access the original data of the image related to the virtual product as the link information in the form of the NFT.

The above storage and management step generates copy data and a unique key related to the virtual product when created in the form of the NFT and manages them by matching them to the original data, and when the user proves ownership, the copy data can be accessed through the address information.

The above storage and management step can recover the damaged copy data using the original data when it is determined that the copy data has been damaged.

According to an embodiment of the present invention, even if the original data of the virtual product being traded is copied and distributed, the contract information on ownership is stored in the form of an NFT, so that the purchaser (hereinafter referred to as a “consumer customer”) who purchased the virtual product can protect and prove the ownership.

Figures 2 to 5 are drawings for explaining the blockchain technology convergence service system of the metaverse service device of Figure 1.
Figure 6 is a block diagram illustrating the detailed structure of the metaverse service device of Figure 1, and
Figure 7 is a flow chart showing the operation process of the metaverse service device of Figure 1.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Figure 1 is a drawing showing a metaverse service system applying blockchain technology according to an embodiment of the present invention.

As illustrated in FIG. 1, a metaverse service system (hereinafter, “metaverse service system”) (90) applying blockchain technology according to an embodiment of the present invention includes part or all of a user terminal device (100), a communication network (110), a metaverse service device (120), and a third-party device (130).

Here, “including some or all” means that some components, such as a third-party device (130), may be omitted to configure the metaverse service system (90), or some or all of the components configuring the metaverse service device (120) may be integrated into a network device (e.g., a wireless switching device, etc.) configuring the communication network (110), and is explained as including all in order to help sufficient understanding of the invention.

The user terminal device (100) includes various types of devices that access the metaverse service device (120) of Fig. 1 and use the metaverse service integrated with blockchain technology. For example, the user terminal device (100) includes a desktop computer, a laptop computer, a tablet PC, a smartphone, a wearable device worn on the wrist, and even a smart TV.

The user terminal device (100) connects to the metaverse service device (120) and performs operations such as purchasing products on the metaverse screen or purchasing content for use online. Accordingly, the user terminal device (100) according to the embodiment of the present invention includes a seller terminal device that sells products, etc., and a buyer terminal device that connects to the service of the metaverse service device (120) and purchases the products.

For example, a seller terminal of a furniture company selling furniture, etc., can connect to the metaverse service device (120) and register a product. During this product registration process, an image of the product, a 3D modeling image, etc., can be provided. Of course, such product purchases can be provided as a service linked to offline delivery of actual products, but may be limited to purchasing furniture content in a virtual space, and thus the present invention will not be specifically limited to any one form. On the other hand, a buyer terminal can connect to the metaverse service device (120) to purchase virtual content, but can use the service in various ways, such as requesting delivery in connection with an actual product.

In addition, the user terminal device (100) performs an operation for proof of ownership in relation to the virtual product and/or the actual product purchased from the metaverse service device (120). For example, in the case of physical delivery, since the owner is confirmed on site, separate proof of ownership can be omitted. However, in the case of purchasing a virtual product in a metaverse virtual space, since there is a possibility of forgery and alteration, proof of ownership is required, and in this case, an operation for proof can be performed at the request of the metaverse service device (120).

The communication network (110) includes both wired and wireless communication networks. For example, a wired or wireless Internet network may be used or linked as the communication network (110). Here, the wired network includes an Internet network such as a cable network or a public switched telephone network (PSTN), and the wireless communication network includes CDMA, WCDMA, GSM, EPC (Evolved Packet Core), LTE (Long Term Evolution), Wibro, etc. Of course, the communication network (110) according to the embodiment of the present invention is not limited thereto, and may be used, for example, in a cloud computing network under a cloud computing environment, a 5G network, etc. For example, if the communication network (110) is a wired communication network, an access point within the communication network (110) can connect to a telephone exchange, etc., but if it is a wireless communication network, data can be processed by connecting to an SGSN or GGSN (Gateway GPRS Support Node) operated by a communication company, or data can be processed by connecting to various relays such as a BTS (Base Transsive Station), NodeB, or e-NodeB.

The communication network (110) may include an access point. The access point here includes a small base station such as a femto or pico base station that is installed in many buildings. The femto or pico base station is classified according to the maximum number of user terminal devices (100) that can be connected to the small base station. Of course, the access point may include a short-distance communication module for performing short-distance communication such as Zigbee and Wi-Fi with the user terminal devices (100). The access point may use TCP/IP or RTSP (Real-Time Streaming Protocol) for wireless communication. Here, the short-distance communication may be performed in various standards such as Bluetooth, Zigbee, infrared, RF (Radio Frequency) such as UHF (Ultra High Frequency) and VHF (Very High Frequency) in addition to Wi-Fi, and ultra-wideband communication (UWB). Accordingly, the access point can extract the location of the data packet, designate the best communication path for the extracted location, and transmit the data packet along the designated communication path to the next device, such as the metaverse service device (120). The access point can share multiple lines in a general network environment, and includes, for example, a router, a repeater, and a repeater.

The metaverse service device (120) provides a metaverse service that combines blockchain technology to a user terminal device (100), and implements the NFT concept in the metaverse transaction system so that the data of the virtual product to be traded in the metaverse service, rather than the target data or copy data and ownership, can be stored as an independent data form implemented in blockchain so that forgery and tampering cannot be prevented and permanently preserved. Through this utilization, even if the original data of the virtual product traded is copied and distributed, the contract information on ownership is stored in the form of an NFT, so that the purchaser who purchased the virtual product can protect and prove the ownership.

Through this, the metaverse service device (120) can improve the problem of asset management on the metaverse, especially rights claim and ownership proof, which are difficult to solve with the concept of conventional commercial transactions and personal transactions. In other words, the limitation of virtual goods, i.e. objects in virtual reality, is that independent unique identification of the data itself is impossible because the replicated digital data and the original data are completely identical data, but the embodiment of the present invention can be seen as solving this problem.

More specifically, the metaverse service device (120) according to an embodiment of the present invention performs an operation of registering a virtual product in response to a service request from a seller terminal device for trading virtual products. In this process, the metaverse service device (120) may perform various additional operations to verify the original author of the virtual product registered by the seller terminal device, and representative examples thereof may include a resident registration number, a phone number, or a password set by the buyer. In addition, the metaverse service device (120) provides a service in response to a service request from a buyer terminal device of a buyer who purchases a virtual product using the metaverse service. For example, when a virtual product is purchased from a buyer terminal device, data related thereto is stored and managed based on a blockchain, and further stored and managed in nodes forming a blockchain in the form of an NFT. Here, the nodes forming the blockchain may be, for example, the user terminal device (100) of FIG. 1, a network device forming a communication network (110), a third-party device (130), etc.

Blockchain is a distributed data storage technology that stores data in blocks, links them in a chain form, and replicates and stores them on numerous computers simultaneously. It is also called a public transaction ledger or distributed transaction ledger. Instead of storing transaction records on a centralized server, it sends transaction details to all users participating in the transaction, and all transaction participants share information and compare it for each transaction, preventing data falsification or modification. When there is a transaction, the blockchain responds to falsification or modification through agreements among nodes connected to the blockchain, and when there is an agreement, data can be modified. The origin of blockchain is not a centralized method that processes data in one place, but a distributed method that processes data in multiple nodes, and in the process, data modifications, etc. are carried out through agreements with multiple nodes, so even if there is an attempt at falsification or modification through hacking or other means in a single node, it can be prevented.

In addition, NFT is a blockchain-based token that cannot be exchanged or duplicated, and thus has uniqueness and scarcity. Of course, token technology has been widely used in the past, so it is not much different. With digital tokens that apply blockchain technology, each token is given a unique recognition value, so it has value and characteristics that cannot be replaced with each other, and thus cannot be exchanged or duplicated. It can be seen that the metaverse service device (120) according to the embodiment of the present invention processes information about a purchaser purchasing a virtual product on the metaverse screen in the form of an NFT, and stores and manages the data in the form of the corresponding NFT in the blockchain.

Above all, according to the embodiment of the present invention, the NFT structure does not contain actual original data (e.g., images, modeling, etc.) in the blockchain, but rather contains address information pointing to the original data, file system information (e.g., file name, creation date, size, creator name, etc.), and transaction information. In addition, in order to protect the original data, the metaverse service device (120) creates a copy of the original data when selling a specific product, adds a unique key to the copy, and manages and points to the copy data with the unique key, not the original data, in the blockchain information. Through this, both the original data and the copy data with the unique key can be sufficiently managed as long as no problems occur. Through this, for example, when trading 3D furniture, the metaverse service device (120) maintains the rights of the consumer customer, such as ownership, through a recovery process as long as the original exists, even if a problem occurs in the copy 3D modeling data with the unique key.

As previously pointed out, in NFT, if someone else registers an NFT before the original author, the original author cannot claim copyright and ownership, and if there is a problem with the file when the original data is registered on the server, there is no problem with proving ownership itself, but the subject of proof may not exist or the original value may be damaged. In the embodiment of the present invention, in order to prevent such problems, the problematic part of the existing NFT was modified to implement its own NFT. The original data of the virtual product is left as is, copy data is created, and this is utilized for the NFT, and blockchain technology is applied. In other words, when a corporate customer sells a virtual product and a consumer customer purchases the virtual product, blockchain technology is applied so that the consumer customer can prove the ownership of the virtual product. The concept of NFT among blockchain technologies is applied.

Above all, the metaverse service system (90) according to the embodiment of the present invention can simultaneously deliver a product purchased in the metaverse in addition to acquiring a virtual product. However, since the proof of ownership is not very effective for a real product, the embodiment of the present invention is limited to virtual products. In addition, the real delivery can be handled by the third party device (130) of Fig. 1.

The third-party device (130) includes various devices that operate in conjunction with the metaverse service device (120) of FIG. 1 to provide a metaverse service according to an embodiment of the present invention. For example, it may include a server or computer of a delivery company related to physical delivery. In addition, the third-party device (130) may include a server or computer of a developer that develops a platform for a metaverse service, that is, a program, and provides it to the metaverse service device (120). In addition, it may include a computer owned by an administrator of a service company that operates the metaverse service device (120).

Figures 2 to 5 are drawings for explaining the blockchain technology convergence service system of the metaverse service device of Figure 1.

Referring to FIGS. 2 to 5, it is necessary to first define what data is needed for transactions on the metaverse and where this information is used. Basically, the information of consumer customers using the metaverse platform is key unique information that should not be arbitrarily added or changed for the purpose of authority or identification of the purchased virtual goods. This unique information is not a concept of ownership rights for virtual goods, but a concept of self-verification, and is a basic premise for defining ownership rights. In other words, since this information is used to define ownership and transaction information for conducting transactions on the metaverse, the data must be managed on the server, i.e., the metaverse service device (120) of FIG. 1, in order to protect legal rights. This information that must be managed includes corporate customer information, corporate customer data copyright information, product information, consumer customer information, etc.

Based on the above information, if the transaction history of virtual goods, transaction history between corporate customers and consumer customers, etc. are linked to the blockchain, a safe metaverse transaction environment can be created that simultaneously protects the rights of consumer customers, the data information to be provided, and the rights and interests of the original creator (or company).

The data that constitutes the transaction specification blockchain can be largely divided into two types: virtual product introduction information and virtual product transaction information. Virtual product introduction information is the first block of the blockchain for each virtual product transaction, and only corporate customers who have the copyright and first sale rights for the virtual product can register it. The purchase history of consumers who purchased virtual products from corporate customers and the history of consumer customers trading purchased virtual products with other consumer customers are connected to the lower blockchain.

The structure of the virtual product introduction information is a block that exists at the top of all virtual product transaction information blocks, and is a block for protecting original copyrights (e.g. product information) rather than transactions. The block includes information on the data being sold (e.g. original author (company or seller) information, original data identifier, etc.).

The structure of virtual goods trading information inherits the existing blockchain data structure, and includes data for metaverse trading (e.g. seller, buyer, trading target identifier, price, transaction date and time) and anti-forgery data, and applies it to the transaction history blockchain after encryption and compression.

In order to smoothly maintain the transaction specification blockchain during service provision, resource consumption between user nodes using the service is essential, but it is difficult to maintain a large amount of blockchain data on the nodes of general users. In addition, since the nodes of general purchase users are not always active, it violates the principle of a single identical blockchain DB. Therefore, the concept of a super node is necessary to record and maintain the blockchain at all times.

Service providers who create platforms and provide services, and sellers (e.g., corporate and individual sellers) who enter the platform to sell and promote products, are obligated to act as super nodes, and synchronization is performed regularly between super nodes to maintain a single, identical blockchain DB. In addition, blockchain data must be maintained to enable tracking of ownership transfers of created items (e.g., transactions between general users).

On the other hand, for general consumer nodes, there is no need to possess all blockchain data, and there is no need to provide additional authority other than access to the history of one's own product purchases. In addition, unlike blockchains that must maintain all data to track the history of product ownership transfers, users have no reason to constantly retain information about a product in a situation where their ownership has been canceled. Therefore, general consumers do not possess all blockchain data, and only need to possess indexing information and public keys that can track their own information within the blockchain.

Instead of having to pay for maintaining physical service resources, merchant users who maintain super nodes can collect market trend information by utilizing all blockchain data registered within the service.

Blockchain data contains information about 'who' sells 'what product', 'when', and 'to whom', but in order to effectively utilize this data, super nodes (e.g. corporate users) that directly connect with the service cloud server that holds the service data, take over authority, and maintain the blockchain can utilize the data to secure and maintain consumer loyalty and go one step ahead in providing customized, high-quality services.

Figure 6 is a block diagram illustrating the detailed structure of the metaverse service device of Figure 1.

As illustrated in FIG. 6, the metaverse service device (120) according to an embodiment of the present invention includes part or all of a communication interface unit (600), a control unit (610), a metaverse service unit (620), and a storage unit (630).

Here, “including some or all” means that some components, such as the storage unit (630), may be omitted to configure the metaverse service device (120), or some components, such as the metaverse service unit (620), may be integrated into other components, such as the control unit (610), and in order to help sufficient understanding of the invention, it is described as including all.

The communication interface unit (600) communicates with the user terminal device (100) and the third-party device (130) via the communication network (110) of Fig. 1, respectively. It provides a metaverse service screen according to a service request from the user terminal device (100), and in the case of a purchaser, if there is a purchase request for a virtual product through the user terminal device (100), it performs an operation for processing it. In the process of performing these operations, the communication interface unit (600) can perform operations such as modulation/demodulation, muxing/demuxing, encoding/decoding, and scaling to convert the resolution, which are obvious to those skilled in the art, and thus, further explanation is omitted.

The control unit (610) is responsible for the overall control operation of the communication interface unit (600), metaverse service unit (620), and storage unit (630) of Fig. 6. For example, when there is a service request from the user terminal device (100) of Fig. 1, the control unit (610) can control the metaverse service unit (620) to execute a program and provide a metaverse service screen accordingly. In addition, when a purchaser holding the user terminal device (100) purchases a virtual product on the virtual screen of the metaverse, the control unit (610) can operate in conjunction with the metaverse service unit (620) to process data thereof.

In other words, the control unit (610) executes the metaverse service unit (620) to generate an NFT according to an embodiment of the present invention and performs an operation for storing and managing it based on a blockchain. In this process, the control unit (610) may share data with a node forming a blockchain, such as a third-party device (130) of FIG. 1, to store and manage NFT data based on a blockchain at the request of the metaverse service unit (620), and control the communication interface unit (600) for this purpose.

The metaverse service department (620) provides a metaverse service for selling virtual products or real products in connection with virtual products. Typically, the metaverse provides a service by allowing users who access the service in a virtual space to participate in the same way as in reality through icons representing the users. Accordingly, it is possible to check where customers who access the service are located in a virtual store. For example, when a furniture company wants to sell furniture and registers the product in the service, it is possible to check which customers are viewing the product through icons, etc. The metaverse service department (620) provides a metaverse service similar to the existing one.

In addition, the metaverse service department (620) can provide a service to enable physical delivery of products sold on the metaverse screen in conjunction with offline, or simply provide a service to sell only virtual products in a virtual space. In the former case, there is no need to worry about forgery because proof of ownership can be achieved through physical delivery, but in the latter case, when selling virtual products and processing their data, the forgery issue needs to be considered. In this regard, when selling virtual products, it is necessary to prove ownership.

The metaverse service unit (620) according to an embodiment of the present invention creates, stores and manages data in the form of an NFT when a virtual product is sold, and at this time, applies blockchain technology to store and manage the data in the form of an NFT based on a blockchain. Above all, in order to solve problems that may arise in existing NFTs, the metaverse service unit (620) maintains original data such as images or modeling data of virtual products as they are in the DB (120a) of FIG. 1, and when there is a sale, creates copy data using the original data of the relevant product, and creates a unique key matching it to store and manage it based on a blockchain. Accordingly, when the copy data is damaged, it is restored using the original data, and when the original data is damaged, it is restored using the copy data. Through this, the problem of damage to images or modeling data of virtual products can be solved.

NFTs can include address information that can access copy data for virtual products being sold, file system information, and transaction information. Therefore, when proof of ownership is required, that is, when a transaction occurs, the copy data of each node can be accessed through the NFT, and the proof of ownership operation can be performed through this process. In this process, when it is determined that a problem has occurred in the copy data with the unique key, for example, the original data can be accessed through the unique key and the copy data can be restored through the original data.

The storage unit (630) stores various types of information or data processed under the control of the control unit (610). Here, since the terms information and data are used interchangeably in practice, the concepts of the terms will not be specifically limited. For example, in image processing, compressed data may include pixel data and encoding information that can determine the form in which the pixel data is compressed. In such cases, the terms need to be distinguished, but they are usually used interchangeably. Therefore, in the embodiment of the present invention, there is no need to distinguish between the two terms, so the terms will not be specifically limited.

For example, when a virtual product is purchased from a user terminal device (100), the storage unit (630) can store purchase information related to the purchase in the storage unit (630) under the control of the control unit (610). Thereafter, at the request of the metaverse service unit (620), the storage unit (630) can output the purchase information and use the information to create an NFT.

In addition to the above, the communication interface unit (600), control unit (610), metaverse service unit (620), and storage unit (630) of Fig. 6 can perform various operations, and other detailed information has been sufficiently explained above, so those contents will be used instead.

The communication interface unit (600), the control unit (610), the metaverse service unit (620), and the storage unit (630) of FIG. 6 according to the embodiment of the present invention are configured as hardware modules that are physically separated from each other, but each module may store software for performing the above operations therein and execute the same. However, the software is a collection of software modules, and each module may be formed of hardware, so there will be no particular limitation on the configuration, such as software or hardware. For example, the storage unit (630) may be hardware, such as storage or memory. However, since it is also possible to store information (repository) in a software manner, there will be no particular limitation on the above.

Meanwhile, as another embodiment of the present invention, the control unit (610) may include a CPU and a memory, and may be formed as a single chip. The CPU may include a control circuit, an operation unit (ALU), a command interpretation unit, and a registry, and the memory may include a RAM. The control circuit may perform a control operation, the operation unit may perform an operation of binary bit information, and the command interpretation unit may include an interpreter or a compiler to convert a high-level language into machine language and vice versa, and the registry may be involved in software data storage. According to the above configuration, for example, at the beginning of the operation of the metaverse service device (120), a program stored in the metaverse service unit (620) may be copied and loaded into the memory, that is, the RAM, and then executed, thereby rapidly increasing the data operation processing speed.

Figure 7 is a flowchart showing the operation process of the metaverse service device of Figure 1.

For convenience of explanation, referring to FIG. 7 together with FIG. 1, the metaverse service device (120) according to the embodiment of the present invention provides a metaverse service screen for selling virtual goods (e.g., furniture, etc.) in response to a service request from a user terminal device (100) (S700). Of course, before this, the seller of the user terminal device (100) can perform a procedure for registering a virtual good. Images or 3D modeling data related to the virtual good can be registered.

In addition, when a user of a user terminal device (100) purchases any virtual product on the service screen of the provided metaverse, the metaverse service device (120) generates address information and contract information on ownership linked to copy data for the original data (e.g., image, modeling data, etc.) of the virtual product in the form of an NFT and stores and manages it in a node forming a blockchain (S710).

In other words, when a virtual product is purchased, the metaverse service device (120) copies the original data of the virtual product to create copy data, stores the copy data in connection with the original data, and creates address information, etc. pointing to the copy data for the NFT created for use in blockchain technology, so that when there is proof of ownership, the copy data is accessed through the address information to perform the corresponding operation. In the process, if the original data or copy data is damaged, for example, when the copy data is damaged, it is restored through the original data, thereby enabling safe transactions in the transaction system through the metaverse.

In addition to the above, the metaverse service device (120) of Fig. 1 can perform various operations, and other detailed information has been sufficiently explained above, so those contents will be used instead.

Meanwhile, even if all the components constituting the embodiments of the present invention are described as being combined as one or operating in combination, the present invention is not necessarily limited to such embodiments. That is, within the scope of the purpose of the present invention, all of the components may be selectively combined and operated one or more times. In addition, although all of the components may be implemented as independent hardware, some or all of the components may be selectively combined and implemented as a computer program having a program module that performs some or all of the functions combined in one or more hardware. The codes and code segments constituting the computer program may be easily inferred by a person skilled in the art of the present invention. Such a computer program may be stored in a non-transitory computer readable medium and read and executed by a computer, thereby implementing the embodiments of the present invention.

Here, the non-transitory readable storage medium means a medium that semi-permanently stores data and can be read by a device, rather than a medium that stores data for a short period of time, such as a register, cache, or memory. Specifically, the above-described programs can be stored and provided on a non-transitory readable storage medium, such as a CD, DVD, hard disk, Blu-ray disk, USB, memory card, or ROM.

Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and various modifications may be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. Furthermore, such modifications should not be individually understood from the technical idea or prospect of the present invention.
