Description

A METHOD AND A DEVICE FOR PROVING THE RIGHTS OF INVESTMENT ASSETS THROUGH NFT DIVISION AND MERGING

[0001] Embodiments of the present invention relate to a method and device for proving rights to investment assets through NFT division and merger.

[0002] With the recent advancement of blockchain technology, Non-fungible Token (NFT) technology, which authenticates original data, is also advancing. NFTs can be implemented by recording transactions for each distinct token on the blockchain and linking the tokens to external data. Because the associated tokens are recorded on the blockchain in a decentralized manner, NFTs for specific data are tamper-proof. Furthermore, verifying the NFT authenticates the authenticity of the specific data.

[0003] Accordingly, services that utilize the characteristics of these NFTs to link them with artwork or real estate and provide multiple income securities or STOs (Security Token Offerings) have been proposed and are currently widely used.

[0004] However, in cases where the value of each asset is not that great, such as artwork by an unknown artist, small-scale real estate, or patents, it is difficult to value them or the investment scale is small, so they are not being utilized as income securities or STOs using NFTs.

[0005] The present invention has been devised based on the problems and background technology described above, and provides a method and device for a service for proving rights to investment assets, which allows even assets of small value to be combined and utilized as the subject of a profit security or STO using NFT by configuring a basic asset NFT by combining a plurality of small-scale rights assets as a single asset combination portfolio, and providing a service for issuing NFTs and linking them with income securities.

[0006] According to an embodiment of the present invention for solving the above-described problem, a method for operating a computing device connected to a blockchain network comprises the steps of: receiving application information for issuing a non-fungible token (NFT) certificate of right of asset combination portfolio information from the blockchain network; verifying asset-specific value authentication information corresponding to the asset combination portfolio information through an institution database; issuing, through the blockchain network, an underlying asset NFT including the asset combination portfolio information and the verified asset-specific value authentication information; and performing one or more NFT asset portfolio processing according to transaction application information corresponding to the underlying asset NFT, wherein the one or more NFT asset portfolio processing comprises: new issuance processing of the underlying asset NFT; and split NFT issuance processing for splitting the asset combination portfolio information and the asset-specific value authentication information of the underlying asset NFT into one or more preset asset units and issuing each as a split NFT; Or, it includes a merge NFT issuance process that merges a plurality of split NFTs that have been issued separately and issues a merged NFT, and further includes a revenue security transaction processing step that issues a revenue security linked to at least one of the underlying asset NFT, the split NFT, and the merged NFT, and records the issuance information of the revenue security on one or more blockchain networks.

[0007] In addition, the method according to an embodiment of the present invention for solving the above-described problem can be implemented as a computer program stored in a computer-readable medium to execute the method in combination with hardware.

[0008] In addition, a device according to an embodiment of the present invention for solving the above-described problem comprises: a computing device connected to a blockchain network, a transaction application information processing unit for receiving application information for issuing a non-fungible token (NFT) right certificate of asset combination portfolio information from the blockchain network; a rights verification processing unit for verifying asset-specific value authentication information corresponding to the asset combination portfolio information using an institutional database; And, through the blockchain network, an asset portfolio processing unit that issues an underlying asset NFT including the asset combination portfolio information and the verified asset-specific value authentication information, and performs one or more NFT asset portfolio processing according to transaction application information corresponding to the underlying asset NFT, wherein the one or more NFT asset portfolio processing includes new issuance processing of the underlying asset NFT, split NFT issuance processing that divides the asset combination portfolio information and the asset-specific value authentication information of the underlying asset NFT into one or more preset asset units and issues each as a split NFT, and merge NFT issuance processing that merges a plurality of split NFTs that have been split and issues a merge NFT, and further includes a revenue securities transaction processing that issues a revenue securities linked to at least one of the underlying asset NFT, the split NFT, and the merge NFT, and records the issuance information of the revenue securities on one or more blockchain networks.

[0009] According to an embodiment of the present invention, when configuring an underlying asset NFT, one or more NFT asset portfolio processing can be performed, wherein the one or more NFT asset portfolio processing includes new issuance processing of the underlying asset NFT, split NFT issuance processing for dividing the asset combination portfolio information and asset-specific value authentication information of the underlying asset NFT into one or more preset asset units and issuing each as a split NFT, and merge NFT issuance processing for merging a plurality of split NFTs that have been split and issued, and issuing a merge NFT, and a linked income security corresponding to at least one of the underlying asset NFT, the split NFT, and the merge NFT can be issued.

[0010] Accordingly, the present invention provides a method and device for a service for proving rights to investment assets, which allows even assets of small value to be combined and utilized as the subject of NFT-based securities or STOs by configuring an underlying asset NFT by combining a plurality of small-scale rights assets into a single asset combination portfolio and providing an NFT issuance and revenue security linkage service accordingly.

[0029] Hereinafter, embodiments of the present specification will be described in detail with reference to the drawings.

[0030] FIG. 1 is a diagram illustrating an example of the operating environment of a system according to one embodiment of the present specification. Referring to FIG. 1, one or more user devices (110-1, 110-2) and one or more servers (120, 130, 140) are connected via a network (1). FIG. 1 is merely an example for explaining the invention, and the number of user devices or servers is not limited to that shown in FIG. 1.

[0031] One or more user devices (110-1, 110-2) may be fixed or mobile terminals implemented as a computer system. The one or more user devices (110-1, 110-2) may be, for example, a smart phone, a mobile phone, a navigation device, a computer, a laptop, a digital broadcasting terminal, a PDA (Personal Digital Assistants), a PMP (Portable Multimedia Player), a tablet PC, a game console, a wearable device, an IoT (Internet of Things) device, a VR (Virtual Reality) device, an AR (Augmented Reality) device, etc. For example, in the embodiments, the user device (110) may mean one of various physical computer systems that can communicate with other servers (120 to 140) through a network (1) using a wireless or wired communication method.

[0032] Each server may be implemented as a computer device or multiple computer devices that communicate with one or more user devices (110-1, 110-2) via a network (1) to provide commands, codes, files, contents, services, etc. For example, the server may be a system that provides each service to one or more user devices (110-1, 110-2) connected via the network (1). As a more specific example, the server may provide a service (e.g., provision of information, etc.) intended by an application to one or more user devices (110-1, 110-2) through an application as a computer program that is installed and run on one or more user devices (110-1, 110-2). As another example, the server may distribute a file for installing and running the above-described application to one or more user devices (110-1, 110-2) and receive user input information to provide a corresponding service.

[0033] FIG. 2 is a block diagram illustrating the internal configuration of a computing device (200) according to one embodiment of the present specification. This computing device (200) may be applied to one or more user devices (110-1, 110-2) or servers (120-140) described above with reference to FIG. 1, and each device and server may have the same or similar internal configuration by adding or excluding some components.

[0034] Referring to FIG. 2, a computing device (200) may include a memory (210), a processor (220), a communication module (230), and a transceiver (240). The memory (210) is a non-transitory computer-readable recording medium and may include a non-permanent mass storage device such as a random access memory (RAM), a read only memory (ROM), a disk drive, a solid state drive (SSD), a flash memory, etc. Here, the non-permanent mass storage device such as a ROM, an SSD, a flash memory, a disk drive, etc. may be included in the above-described device or server as a separate permanent storage device distinct from the memory (210). In addition, the memory (210) may store an operating system and at least one program code (for example, a browser installed and operated on a user device (110), or a code for an application installed on a user device (110) to provide a specific service). These software components may be loaded from a computer-readable recording medium separate from the memory (210). This separate computer-readable recording medium may include a computer-readable recording medium such as a floppy drive, a disk, a tape, a DVD / CD-ROM drive, a memory card, etc.

[0035] In another embodiment, the software components may be loaded into the memory (210) via a communication module (230) rather than a computer-readable recording medium. For example, at least one program may be loaded into the memory (210) based on a computer program (e.g., the application described above) that is installed by files provided by developers or a file distribution system (e.g., the server described above) that distributes the installation files of the application via a network (1).

[0036] The processor (220) may be configured to process instructions of a computer program by performing basic arithmetic, logic, and input / output operations. Instructions may be provided to the processor (220) by the memory (210) or the communication module (230). For example, the processor (220) may be configured to execute instructions received according to program code stored in a storage device such as the memory (210).

[0037] The communication module (230) can provide a function for the user device (110) and the server (120 - 140) to communicate with each other via the network (1), and can provide a function for each of the device (110) and / or the server (120 - 140) to communicate with other electronic devices.

[0038] The transceiver (240) may be a means for interfacing with an external input / output device (not shown). For example, external input devices may include devices such as a keyboard, mouse, microphone, camera, etc., and external output devices may include devices such as a display, speaker, haptic feedback device, etc.

[0039] As another example, the transmitter / receiver (240) may be a means for interfacing with a device that integrates input and output functions, such as a touch screen.

[0040] In addition, in other embodiments, the computing device (200) may include more components than the components of FIG. 2 depending on the nature of the device to which it is applied. For example, when the computing device (200) is applied to a user device (110), it may be implemented to include at least some of the above-described input / output devices, or may further include other components such as a transceiver, a Global Positioning System (GPS) module, a camera, various sensors, a database, etc. As a more specific example, when the user device is a smartphone, it may be implemented to further include various components that are generally included in a smartphone, such as an acceleration sensor or a gyro sensor, a camera module, various physical buttons, buttons using a touch panel, input / output ports, and a vibrator for vibration.

[0041] Below, a computing device (200) operating based on FIGS. 1 and 2 is described. Here, the computing device (200) may be a device that communicates with an NFT and revenue certificate linkage service platform via a network. Furthermore, the server (110) described above may be configured to build a service platform and provide services through the service platform. As another example, the server may be configured to build the trading platform described below and provide services through the trading platform, but is not limited to a specific form. That is, the server may manage and control the platform provided to the device, but may not be limited thereto.

[0042] As another example, the computing device (200) and server (120-140) described above may be a type of node operating based on a blockchain (or blockchain network). For example, blockchain may be a ledger management technology based on distributed computing technology that creates a distributed data storage environment based on chain-like links generated based on a P2P method, preventing arbitrary modification and recording the results of data changes. Here, the distributed data storage environment may be built based on each node associated with the blockchain, and the computing device (200) and server described above may be any one of the nodes. As a specific example, transactions occurring based on NFTs may be recorded on each and every node within the blockchain, thereby preventing arbitrary manipulation. For example, the computing device (200) and server may include and record a ledger for data processing, such as data creation and modification, based on the blockchain, but the present invention may not be limited thereto. Furthermore, as an example, the blockchain and its based operations may be configured based on a user account. For example, an airdrop based on an NFT or NFT / TOKEN linked to a blockchain can be performed based on a user account. The user account can be linked to each computing device (200), and the above-described information can be verified based on this. For example, if the user account is newly linked to another computing device (200), the above-described information can be verified through the newly linked other computing device (200). In other words, the user account can be linked to and operated with the computing device (200), but may not be limited to a specific computing device (200) and may not be limited to the type of computing device (200). For convenience of explanation, the computing device (200) that provides or receives services through the NFT service platform or the income securities linkage platform is referred to as a device below, but may not be limited thereto.That is, the device may be a device used by each user, such as a user, owner, buyer, and seller, and each user may receive services provided through the service platform or trading platform through his or her own device.

[0043] Additionally, the service platform or trading platform may be a platform operating based on the aforementioned server. For example, the platform may be controlled by a single server. Alternatively, the platform may be controlled by a server comprised of multiple nodes based on blockchain and edge computing, and is not limited to a specific form. For convenience, the following description will focus on the service platform and trading platform, but the scope of the description may not be limited thereto.

[0044] FIG. 3 is a block diagram illustrating a service processing unit and its configuration according to an embodiment of the present invention.

[0045] First, referring to FIG. 3, a computing device (200) according to an embodiment of the present invention may further include a service processing unit (250). The service processing unit (250) may be configured as a processor module that performs various service processes for processing service data according to an embodiment of the present invention among the logic and input / output operations processed by the processor (220). The computing device (200) may configure the service processing unit (250) within the processor (220) or perform service processing using data processed from a device equipped with the service processing unit (250) as an external processor, thereby providing the generated service data to a user device (110) or one or more servers (120, 130, 140).

[0046] According to this processing, a user device (110) or one or more servers (120, 130, 140) may receive service data configured by the operation of a service processing unit (250) according to an embodiment of the present invention and output it through a display device or use it to transmit and receive data for service provision through an external network.

[0047] In such processing, the service processing unit (250) according to an embodiment of the present invention can access a blockchain network, issue a basic asset NFT based on asset combination portfolio information, perform a corresponding split NFT issuance and / or merged NFT issuance process, and perform issuance and distribution processing of profit securities linked thereto.

[0048] To this end, referring to FIG. 3, the service processing unit (250) may include a network connection unit (251), a transaction application information processing unit (252), a rights confirmation verification unit (253), an asset portfolio processing unit (254), a profit securities information processing unit (255), and a platform service unit (256).

[0049] First, the network connection unit (251) is configured to enable the computing device (200) to access one or more blockchain networks, and the one or more blockchains may be configured as blockchain networks capable of recording NFT-based transactions using an asset portfolio. For example, the blockchain network may configure the basic asset NFT, the split asset NFT, and / or the merged asset NFT as NFT tokens with unique identification information (ID) that can distinguish each type, and record the corresponding asset transaction on the blockchain, thereby making it impossible to manipulate and proving that it is an actual original. Here, the blockchain node (or blockchain network) connected and configured through the network connection unit (251) is not limited to a specific form and may be independent of the type of blockchain network. In addition, a smart contract may be used for the above-described original verification and transaction.

[0050] In this way, when the preparation configuration for providing a blockchain network connection and platform service is completed by the network connection unit (251), the transaction application information processing unit (252) can obtain transaction application information from the blockchain network and transmit the asset portfolio processing request information accordingly to the rights confirmation verification unit (253) or the asset portfolio processing unit (254).

[0051] Here, the transaction request information may correspond to an underlying asset NFT corresponding to the asset combination portfolio information according to an embodiment of the present invention, and may include at least one of an application for issuing an underlying asset NFT, an application for issuing a split NFT, and an application for issuing a merged NFT. For each of these issuance processes, the asset portfolio processing unit (254) may include a basic NFT issuance processing unit (2541), a split NFT issuance processing unit (2542), and a merged NFT issuance processing unit (2543).

[0052] First, the underlying asset NFT is an NFT that composes various sized assets such as artwork, real estate, and patents as a single asset combination portfolio, and may be a certificate of rights to the asset combination portfolio issued based on value authentication information issued according to verification by a corresponding authentication agency server (300), and the authenticity of the original and transaction history information may be verified through a blockchain network.

[0053] In order to issue such underlying asset NFTs, the transaction application information processing unit (252) receives application information for issuing NFT (non-fungible token) certificate of rights of asset combination portfolio information through the network connection unit (251), and the received application information can be transmitted to the rights confirmation verification unit (253) and the asset portfolio processing unit (254).

[0054] And the rights confirmation verification unit (253) identifies asset combination portfolio information from the basic asset NFT issuance application information transmitted from the transaction application information processing unit (252), transmits the asset information included in the asset combination portfolio information to the certification authority server (300), and, using the institution database of the certification authority server (300), verifies asset-specific value authentication information corresponding to the asset combination portfolio information, and then transmits the verified asset-specific value authentication information to the asset portfolio processing unit (254).

[0055] Accordingly, the asset portfolio processing unit (254) can issue an underlying asset NFT including the asset combination portfolio information and the verified asset-specific value authentication information via the blockchain network. To issue an underlying asset NFT, a predefined smart contract can be executed by the blockchain network, and asset contract information and asset portfolio combination information specified by the smart contract are generated. Permanent proof of authenticity is enabled by issuing an NFT based on the asset contract information and asset portfolio combination information.

[0056] Here, the asset contract information of the underlying asset NFT may include asset type information, owner information, certification authority information, disposal method information, etc., and the portfolio combination information may include at least one of asset identification information, asset weight information, asset value information, and value authentication information verified by the certification authority server (300).

[0057] Meanwhile, if the transaction application information includes sales information of the first asset unit corresponding to the target asset NFT, the transaction application information processing unit (252) transmits a request for issuing a split NFT of the target asset NFT according to the sales information to the asset portfolio processing unit (254), thereby initiating the split NFT issuance processing of the split NFT issuance processing unit (2542).

[0058] Here, the sales information may include target NFT identification information, the first asset unit information, and sales amount information. Furthermore, the target NFT identification information may include target asset NFT identification information indicating an underlying asset NFT or an asset NFT derived from the underlying asset NFT.

[0059] Additionally, the first asset unit information may include asset identification information and quantity information indicating assets to be excluded from sale among the asset combination portfolio included in the target asset NFT.

[0060] In addition, the sales amount information indicates the sales amount corresponding to the first asset unit information, and is transmitted to the revenue securities information processing unit (255) to be used for calculating dividends for revenue securities corresponding to the target asset NFT.

[0061] Meanwhile, when a request for processing of a split NFT issuance is made, the split NFT issuance processing unit (2542) obtains target asset NFT identification information indicating a base asset NFT or an asset NFT derived from the base asset NFT from the sales information, obtains context information of the target asset NFT from the target asset NFT identification information, and can identify asset combination portfolio information and asset-specific value authentication information from the context information of the target asset NFT.

[0062] Accordingly, the split NFT issuance processing unit (2542) can first create a first split NFT corresponding to the asset combination portfolio data that splits the asset combination portfolio information of the identified split target asset NFT into the first asset unit, and share it on the first blockchain network.

[0063] In addition, the split NFT issuance processing unit (2542) can generate a second split NFT corresponding to the asset combination portfolio data from which the first asset unit is excluded from the asset combination portfolio information of the target asset NFT, and share and process it on the second blockchain network.

[0064] Here, the first blockchain network and the second blockchain network may be the same network, but they may also be configured as different networks. This can be implemented in various ways depending on the operating method of the platform service.

[0065] Accordingly, the asset combination portfolio of the target asset NFT can be divided into a first-partition NFT and a second-partition NFT, and each can include information on the divided asset combination portfolio. For example, if the asset combination portfolio of the target asset NFT includes artwork A and real estate B, and the sales information includes asset unit information corresponding to artwork A, the asset combination portfolio information of the first-partition NFT can be configured to include only artwork A, and the asset combination portfolio information of the second-partition NFT can be configured to include only real estate B, excluding artwork A.

[0066] Through the split processing of the split NFT issuance processing unit (2542) of this type, even if various assets are mixed in different ratios in one asset NFT certificate, split selling or split buying processing according to the sale of partial asset units is possible, and such transaction history can be shared and tracked through the blockchain network.

[0067] Meanwhile, if the transaction application information includes combined information of a second asset unit for the target asset NFT, the transaction application information processing unit (252) transmits a merged NFT issuance request according to the combined information to the asset portfolio processing unit (254), thereby initiating the merged NFT issuance processing of the merged NFT issuance processing unit (2543).

[0068] When a merge NFT issuance request is identified, the merge NFT issuance processing unit (2543) first uses the agency database of the certification agency server (300) to receive second value authentication information corresponding to the second asset unit and generates a second asset portfolio NFT.

[0069] In addition, the merged NFT issuance processing unit (2543) can generate merged asset portfolio information by merging the asset combination portfolio information of the target asset NFT and the asset portfolio information of the second asset portfolio NFT, calculate merged value information based on a comparison between the asset-specific value authentication information of the target asset NFT and the second value authentication information, and issue the merged NFT based on the merged asset portfolio information and the merged value information.

[0070] More specifically, for example, the merge NFT issuance request may include target asset NFT information that is the subject of the merge and combined information of the second asset unit to be merged. The combined information may include unique asset information and quantity information for the second asset unit to be newly merged, and the merge NFT issuance processing unit (2543) may transmit the unique asset information to the certification authority server (300) to obtain the authentication information of the verified second asset unit.

[0071] In addition, the merged NFT issuance processing unit (2543) can use the verified authentication information of the second asset unit to issue a second asset portfolio NFT including the unique asset information and quantity information of the second asset unit and the authentication information, and share it through a blockchain network.

[0072] Accordingly, the merged NFT issuance processing unit (2543) can generate merged asset portfolio information by merging the asset combination portfolio information of the target asset NFT that is the target of merging and the asset portfolio information of the second asset portfolio NFT, calculate merged value information based on a comparison between the asset-specific value authentication information of the target asset NFT and the second value authentication information, and issue the merged NFT based on the merged asset portfolio information and the merged value information.

[0073] The merged NFT issued in this manner may include, as merged asset portfolio information, asset-specific information and quantity information of the entire asset combination portfolio, and, as merged value information, value authentication information and weight information corresponding to each merged asset-specific information may be included.

[0074] For example, if the asset combination portfolio of the target asset NFT to be merged includes artwork A, and the second asset unit information to be merged includes asset unit information corresponding to real estate B, the merged NFT may include asset combination portfolio information in which artwork A and real estate B are merged, and may include value authentication information corresponding to the asset-specific information of each artwork A and real estate B, and value proportion information based on a comparison of their respective values. This value proportion information may be calculated as information on the proportion of each unique asset among the total asset value.

[0075] Through the merge processing of the merged NFT issuance processing unit (2543) of this type, even if the assets are small, various assets can be configured as a single asset combination portfolio NFT, and issuance of income securities, dividend sharing, and transactions can be made accordingly, and the transaction history can be shared and tracked through the blockchain network.

[0076] The income securities information processing unit (255) performs income securities linkage processing in response to the NFTs issued according to the basic NFT issuance processing, split NFT issuance processing, and merged NFT issuance processing described above, and transmits linkage information according to the income securities linkage to the platform service unit (256) so that the income securities platform service through the platform service unit (256) is provided to one or more user devices (110). Here, the income securities platform service may include a sales and distribution service of income securities linked to NFTs, a dividend distribution or reservation service, and a re-linkage service according to the split or merge of NFT securities.

[0077] In particular, the re-linking service may include a service that, when a first split NFT and a second split NFT are issued in a split manner in the split NFT issuance processing unit (2542) and a first pre-issued revenue security corresponding to the target asset NFT that is the subject of the split exists, re-links the pre-issued first revenue security to the second split NFT and shares revenue security issuance information including the re-linking issuance information on the second blockchain network. Accordingly, the first revenue security can be re-linked to correspond to the second split NFT and sold and distributed.

[0078] In addition, the revenue securities information processing unit (255) calculates the first dividend amount of the first revenue securities linked to the target asset NFT based on the sales information corresponding to the issuance of the split NFT, and performs dividend processing for one or more owner nodes for the target asset NFT as the sales amount according to the asset combination portfolio exclusion processing of the first asset unit, so that dividend information can be provided to each user device (110) through the platform service unit (256).

[0079] Meanwhile, the revenue securities information processing unit (255) may further perform processing for sharing on a separate first blockchain network by issuing a separate second revenue securities corresponding to the first split NFT excluded by the sale, based on the above-described split NFT issuance processing. Accordingly, another revenue securities linkage platform service processing can also be performed for the first asset unit of the first split NFT separated by the sale processing.

[0081] FIG. 4 is a flowchart for explaining an operation method of a computing device according to an embodiment of the present invention.

[0082] Referring to FIG. 4, first, the computing device (200) receives application information for issuing a non-fungible token (NFT) certificate of rights for asset combination portfolio information from a blockchain network (S101).

[0083] Then, the computing device (200) verifies the asset-specific value authentication information corresponding to the asset combination portfolio information using the database of the authentication authority server (300) (S103).

[0084] And, the computing device (200) issues an underlying asset NFT including the asset combination portfolio information and the verified asset-specific value authentication information (S105).

[0085] Thereafter, the computing device (200) processes one or more NFT asset portfolios according to transaction application information corresponding to the target asset NFT, and issues at least one of a split NFT and a merged NFT (S107).

[0086] And, the computing device (200) issues a revenue security linked to at least one of the basic asset NFT, the split NFT, and the merged NFT, and records the issuance information of the revenue security on one or more blockchain networks (S109).

[0087] Thereafter, the computing device (200) performs dividend information distribution processing corresponding to the linked income security for at least one of the underlying asset NFT, the split NFT, and the merged NFT, according to the occurrence of a transaction based on the NFT sales information (S111).

[0088]

[0089] FIG. 5 illustrates issuance information of an NFT according to an embodiment of the present invention, FIG. 6 is a diagram for explaining the basic asset issuance, split issuance, and merged issuance processes of an NFT according to an embodiment of the present invention, and FIG. 7 is a diagram for explaining the NFT reference structure and rights tracking process according to an embodiment of the present invention.

[0090] First, as illustrated in FIG. 5(A), FIG. 5(B), and FIG. 5(C), asset NFTs according to embodiments of the present invention can be divided into basic asset NFTs, split NFTs, and merged NFTs, and each of the authentication information, issuance information, and ownership information can be recorded on a blockchain network.

[0091] Additionally, as previously explained, the underlying asset NFT may be a base NFT generated by the initial input of asset combination portfolio information, from which split NFTs and merged NFTs may be issued. These may be sequentially derived in various tree orders and forms, as illustrated in Figure 6. This derivation process, as automated contract information in the form of a smart contract, can be pre-established and shared on the blockchain network, making subsequent forgery impossible.

[0092] For example, as illustrated in FIG. 6, the underlying asset NFT can be derived from various asset NFTs by being split and merged and issued into various NFTs. Referring to FIG. 6, the target asset NFT a can be split into NFT c and NFT d, which are split asset NFTs, through the processing of the split NFT issuance processing unit (2542), and a new NFT n, in which NFT m is merged into NFT I, can be issued by the merge NFT issuance processing unit (2543). In addition, the income securities information processing unit (255) can perform issuance information processing and dividend management for income securities corresponding to each of these asset NFTs, and provide an asset management service using the same through the platform service unit (256).

[0093] Additionally, as illustrated in FIG. 7, each NFT can be assigned identification information corresponding to the previous block, so that the blockchain network can be configured so that each derivative NFT can be sequentially traced back to the initially generated underlying asset NFT, enabling proof of the overall original authenticity of the underlying and derivative NFT assets.

[0094] That is, various embodiments of this specification may include cases where both NFT splitting and merging are performed, cases where only splitting is performed (which may include NFT issuance), and cases where only merging is performed (which may include NFT issuance).

[0095] Meanwhile, FIG. 8 is a drawing for explaining the setting of a limit on the number of divisions and merges according to an embodiment of the present invention.

[0096] Referring to FIG. 8, as shown in FIG. 8(A) and FIG. 8(B), it is preferable that the number of asset NFT divisions and the number of merge targets be limited to only two. This is because, if multiple asset divisions or multiple asset merges are allowed as shown in FIG. 8(C) and FIG. 8(D), the complexity of history tracking and derivative NFT configuration significantly increases, which may cause delays in information processing by the platform service unit (256).

[0097]

[0098] And, FIGS. 9 and 10 are drawings for exemplarily explaining the contents of the revenue securities linkage and platform service of the service processing unit according to an embodiment of the present invention.

[0099] First, referring to FIG. 9, a request may be made to issue an underlying asset NFT for an asset portfolio including artwork A, real estate B, and patent K. In this case, the rights verification unit (253) verifies and processes asset-specific information for artwork A, real estate B, and patent K, as well as corresponding value authentication information, from the authentication authority server (300).

[0100] In addition, the basic NFT issuance processing unit (2541) can generate and issue a basic asset NFT by generating portfolio combination information consisting of verified authentication information and asset-specific information for each of artwork A, real estate B, and patent K, and inputting contract information for an issuance request corresponding to the generated portfolio combination information. Here, the contract information may include asset type information, owner information, certification agency information, and disposal method information, and the portfolio combination information may include overall asset value information and value proportion information for each asset.

[0101] In addition, the split NFT issuance processing unit (2542) can process asset split NFTs based on sales information of some assets for the underlying asset NFT. For example, a 100% sale of artwork A can be exemplified. Accordingly, a first split NFT can be generated, and a second split NFT can be generated that represents combined information on the remaining asset portfolio excluding artwork A.

[0102] Meanwhile, the platform service unit (256) may allocate revenue securities information corresponding to each underlying asset NFT, first-partition NFT, or second-partition NFT through the revenue securities information processing unit (255) and perform corresponding transaction brokerage services. Here, the revenue securities information may include revenue securities information in which the asset NFT is divided into multiple pieces and a dividend rate and value are assigned, or may include separate STO (Security Token Offering) information. Here, the multiple pieces may be, for example, 100 pieces, and the platform service unit (256) may perform securities sales and distribution transaction brokerage for each piece accordingly.

[0103] Additionally, the platform service unit (256) may perform dividend distribution or reserve processing corresponding to the sales information when asset division based on sales information is processed. Furthermore, the income securities information processing unit (255) may maintain the sales and distribution system for income securities by relinking the first income securities assigned to the underlying asset NFT to the second divided NFT. Here, the relinked income securities may be referred to as second income securities, and their value and contract terms may be set differently from those of the first income securities.

[0104] Meanwhile, referring to FIG. 10, the second-partition NFT, which was divided according to the first sales information, may also be further divided into a third-partition NFT and a fourth-partition NFT according to the second sales information. In this case, the platform service unit (256) may perform a revenue security linkage replacement service through the revenue security information processing unit (255). Through this revenue security linkage replacement service, the existing second revenue security, which was re-linked to correspond to the second-partition NFT, may also be replaced and linked to the fourth revenue security corresponding to the fourth-partition NFT. Therefore, the replacement linkage process may be implemented as an example of the re-linkage process for the fourth-partition NFT to a revenue security.

[0105]

[0106] The embodiments described above may be implemented at least in part as computer programs and recorded on a computer-readable recording medium. A computer-readable recording medium on which a program for implementing the embodiments is recorded includes any type of recording device that stores data that can be read by a computer. Examples of computer-readable recording media include ROMs, RAMs, CD-ROMs, magnetic tapes, and optical data storage devices.

Furthermore, functional programs, codes, and code segments for implementing the embodiments will be readily understood by those skilled in the art to which the embodiments pertain.

[0107] Although the present specification has been described with reference to the embodiments illustrated in the drawings, these are merely exemplary, and those skilled in the art will understand that various modifications and variations of the embodiments are possible. However, such modifications should be considered within the technical protection scope of the present specification. Therefore, the true technical protection scope of the present specification should be determined to include other implementations, other embodiments, and equivalents to the claims, based on the technical spirit of the appended claims.
