Description

Distribution history management system and method using NFT token {THE SYSTEM AND THE METHOD FOR MANAGING DISTRIBUTION HISTORY USING NON-FUNGIBLE TOKEN}

The present invention relates to a distribution history management system and method using NFT tokens (Non-Fungible Tokens), and more particularly, to generate NFT tokens for each distribution subject through a blockchain network to track the distribution history of each distribution subject. A system and method for managing the distribution history of distribution objects by recording information.

In recent years, blockchain technologies have been widely used for the distribution history and tracking management of products and raw materials. In addition, as a national test project, blockchain has been applied to the distribution of agricultural products and livestock products to which blockchain has been applied, and it is being appropriately used as a system to track and manage distribution history.

However, a system that simply records and manages the distribution history on the blockchain network to prevent forgery and falsification of data and guarantees integrity, manages the history of distribution objects that need to be prevented from misuse by thoroughly tracking and managing the distribution history. It is a reality that it is difficult to do, and a new way of managing distribution history is needed.

For example, in the case of distribution objects such as hemp (HEMP), cultivation -> processing -> product production, cultivation, processing, and production management can only be performed by a person authorized by the regulatory/supervisory body at each stage, 1) distribution objects for each stage Changes in and 2) distribution history must be thoroughly tracked, and there is a need to separately manage the authority to access or record the history of each distribution object.

In other words, it is difficult to apply a product and raw material tracking management system using block chain technology when distribution history management by an authorized person is required for each time point in which a distribution object is transformed or processed.

In other words, in order to prevent the misuse and abuse of distribution objects that require the management of regulatory supervisory bodies, such as hemp (HEMP), the issuance and management of NFT tokens that can be traced seamlessly across the Seed-to-Product distribution stage are the authority of the regulatory supervisory authority. There is a need for a method for tracking management objects using NFT tokens so that authorization/permission can be granted to the person who manages the distribution history for each distribution stage, and the right to manage the distribution history can be revoked in real time when a violation occurs.

KR 10-1871468 B

The present invention has been devised to solve the above problems. The present invention creates a non-fungible token for each distribution object through a blockchain network and records the distribution history information of each distribution object to produce, process, and produce a specific distribution object. Its purpose is to provide a history management system that tracks all stages of distribution.

In order to achieve the above object, the distribution history management method using the NFT token of the present invention includes (a) at least one distribution history record permission terminal transmitting distribution history data related to a distribution history management object to a server, (b) ) The server stores the distribution history data in the object history management database, generates a transaction including the distribution history data or metadata address information in which the distribution history data is stored, propagates it to the blockchain network, and transmits it to the token issuance management terminal Requesting the issuance of an NFT token corresponding to the distribution history management object, (c) the token issuance management terminal containing the distribution history data or metadata address information propagated to the blockchain network as unique information (# n) generating a transaction for issuing an NFT token and propagating it to a blockchain network; and (d) at least one or more participating nodes generating a block containing the at least one or more transaction information using a consensus algorithm preset in the blockchain network. It includes the step of creating and recording on the blockchain network.

At this time, in the distribution history management method using the NFT token of the present invention, in the step (c), when the shape of the distribution history management object is changed, all distributions stored in the Nth (#n) NFT token of the form before the change A transaction for issuing an N+1st (#n) NFT token for a changed form of distribution history management object may be generated by further including history data or metadata address information. In addition, the Nth (#n) and N+1st (#n) NFT tokens further include token serial number information, the token serial number is encrypted and recorded in a blockchain network, and the encrypted token The serial number may be converted into tag information using a QR code or RFID and used.

In addition, in the distribution history management method using the NFT token of the present invention, in step (a), the distribution history recording permission terminal updates the existing distribution history data recorded in the Nth (#n) NFT token issued. In the case of sending distribution history update data that

In the step (b), the server includes all distribution history data or metadata address information stored in the issued Nth (#n) NFT token, but the distribution history update data or updated metadata address information A request is made to the token issuance management terminal to generate an Nth (#n+1) NFT token further including unique information and incinerate the Nth (#n) NFT token, and the token issuance management terminal A transaction requesting generation of a second (#n+1) NFT token is created, and after the Nth (#n+1) NFT token is issued, the Nth (#n) NFT in which the existing distribution history data is stored A step of generating a transaction for burning the token and propagating it to the blockchain network may be further included.

In addition, the distribution history management method using the NFT token of the present invention, based on the smart contract of the blockchain network, the token issuance management terminal related to the generation of the Nth (#n) NFT token and the distribution history record permission When an ownership transfer execution command for the Nth (#n) NFT token is received from all terminals, the ownership transfer command for the NFT token may be executed.

In addition, in the distribution history management method using NFT tokens of the present invention, the consensus algorithm preset in the blockchain network can generate the block when a majority of the at least one participating node reaches a block generation agreement. .

In addition, in the distribution history management method using the NFT token of the present invention, the token issuance management terminal, for each distribution history record permission terminal, records authority and recording so that only distribution history data related to a specific distribution history management object can be recorded. Conditions are set, and if the distribution history recording permission terminal does not satisfy the recording condition or omits the record of distribution history data, the recording authority granted to the distribution history recording permission terminal is changed according to the preset cancellation condition. You can execute the cancel command.

The distribution history system using the NFT token of the present invention includes a blockchain network formed by a distribution history recording permission terminal, a server, a token issuance management terminal, and at least one participating node, and the distribution history recording permission terminal, the server, the above It is composed of a token issuance management terminal and a blockchain network formed by the at least one participating node.

When using a system for managing distribution history information for each distribution history management object in a blockchain network using NFT tokens according to an embodiment of the present invention, the time required for paperwork used to check the distribution history for each distribution history management object and cost savings.

In addition, since the distribution history information is distributed and shared through the blockchain network through an agreement between verified participant nodes, the distribution history information for the distribution history management object can be managed more safely and transparently than the document exchange method in terms of data tampering and manipulation. There is an advantage to being

In addition, since the information recorded in the NFT token is shared only by terminals with access rights, and different rights are granted to each participant, there is an advantage in that data privacy problems can be supplemented.

Specifically, in the case of distribution history management objects such as hemp (HEMP), safety management and quality control standards exist to prevent misuse and abuse, so it is difficult to thoroughly manage product quality, as well as to control the cultivation, harvesting, and distribution process. The reality is that thorough tracking is difficult.

Therefore, the present invention not only records and manages the history of the distribution history management object in real time in the entire process of cultivation, processing, manufacturing, storage, and transfer of the distribution history management object, and manages the right to record the distribution history, Recorded information can be provided only to terminals with access rights.

Furthermore, the present invention issues NFT tokens in which history information related to a specific distribution history management object is recorded as unique information, and an authorized supervisory authority owns and manages it, thereby changing, dividing, Changed histories due to mergers, etc., can be thoroughly managed for each subject of change.

First, when describing the hemp management object, which is a term mentioned in one embodiment of the present invention, the hemp (HEMP) management object is a distribution of seeds, embryos, outposts, flowers, by-products, oil, waste, finished cosmetics, etc. It refers to the hemp management object that changes in various forms depending on the stage.

1 is an exemplary diagram illustrating a hemp (HEMP) distribution management process according to an embodiment of the present invention.

Referring to FIG. 1, in the case of the United States, hemp (HEMP) has a very developed dedicated management tool that is differentiated from other agricultural and marine products due to industrial characteristics. In particular, licenses are issued to various players in the hemp (HEMP) ecosystem, such as Spencerry (retail stores), test labs (component testing facilities), and smoking lounges (cafes), which are not found in other agricultural and marine products, to track and manage distribution history. there is. On the other hand, in the case of Korea, retail transportation and retail are not applicable, but in relation to medical cannabis distribution, cultivation -> manufacturing / processing -> intermediate stage transportation -> ingredient testing -> hemp (HEMP) for each stage of disposal There is a need for a management object distribution management tool.

2 is a schematic diagram of an interworking between a HEMP distribution management system and a narcotics integrated management system (NIMS) operated by the Ministry of Food and Drug Safety according to an embodiment of the present invention.

Figure 3 is a block chain-based hemp (HEMP) management object history management perspective according to an embodiment of the present invention.

Referring to FIG. 2, the integrated narcotics management system is a system for reporting, storing, and monitoring the entire handling of narcotics or psychotropic drugs (export/import, manufacture, sale, etc.) The entire cycle history management system of hemp (HEMP) according to an embodiment of the present invention can be inter-operated with the integrated drug management system in the future.

When interworking with the integrated narcotics management system, the history information on HEMP recorded on the blockchain network is managed through the internal management server 10 connected to the terminal authorized to record the distribution history of HEMP. It can be reported to the system, but if necessary, the terminal with the right to record the history of the Hemp management object receives the authority from the Narcotics Integrated Management System and directly accesses the Hemp management object recorded on the blockchain network. It is also possible to upload or report the history information to the integrated narcotics management system for the history information about the drug.

Referring to Figure 3, all actions taken by all participants in the ecosystem, including private and public sectors, such as regulators, farms, research institutes, manufacturers, transporters, and disposal companies, and the timing of the actions, hemp (HEMP) seeds, outposts, and flowers / Record the history of changes and timing of objects that change in various forms, such as leaves and their processed products, by-products and wastes, on the blockchain network, and the history of the entire cycle of the hemp management object recorded on the blockchain network It aims to provide a system that can monitor and control information in real time by government agencies (Gyeongbuk Provincial Office, Andong City Hall, etc.) and the Ministry of Food and Drug Safety.

Figure 4 is a diagram showing the layers of the hemp (HEMP) distribution management comprehensive system according to an embodiment of the present invention.

Referring to Figure 4, the hemp (HEMP) lifecycle history management system according to an embodiment of the present invention is composed of three main layers (app layer / block chain layer / system, regulation and process layer). Hereinafter, each of the three main layers will be described.

1) The application layer is composed of blockchain network access mobile and web applications equipped with necessary functions for each participating entity in relation to HEMP distribution. That is, related information can be displayed in the application based on the history information recorded in the blockchain network. For example, i) monitoring app application for regulatory authorities that can monitor license management and distribution status in real time, ii) application for farm management that enables cultivation status, inventory management and access control of personnel in charge, iii) hemp (HEMP) Certification management application for certified companies that can measure and manage ingredient content after processing, iv) application for manufacturing and processors that can manage CBD oil extraction details and subdivision management of intermediate objects, and v) warehousing management, inventory management, release management, and sales reporting Applications for possible distributors/exporters may be provided.

2) The blockchain layer consists of a semi-private blockchain that ensures objectively verifiable irreversibility, and clearly defines the nature of the subject, the rights the subject has, and the content of actions such as harvesting and discarding that can be performed with that authority. and traceability, and manage the change history of hemp management objects that change in various forms depending on the distribution stage, such as seeds, embryos, outposts, flowers, by-products, oil, waste, and finished cosmetics, in a flexible and consistent manner. can In addition, it can ensure the security of a closed ecosystem in which only licensed participants can participate.

3) The system/regulation and process layer clearly defines each participant in the industrial ecosystem related to hemp (HEMP) distribution and defines the HEMP distribution network management process through the design of the authorization/permission system and detailed regulations.

5 is an overview diagram of each configuration level of a blockchain layer according to an embodiment of the present invention. A blockchain layer according to an embodiment of the present invention is composed of an actor level (layer), an object level (layer), and a ledger record level (layer).

The blockchain layer according to an embodiment of the present invention is composed of a semi-private blockchain that ensures objectively verifiable irreversibility. In FIG. 5, each participating node, that is, Block Producer 1 to N (Block Producer 1 to N) may generate a block. At this time, each Block Producer is not a single company, but a consortium composed of organizations or companies related to the project, so it is a node composed of authorized persons. In other words, it is defined as a semi-private blockchain because various authorized institutions and companies, rather than a single company, participate as nodes.

In other words, it has a permissioned nature in that only authorized nodes can participate, and since various related institutions/companies can participate as nodes that can create blocks, rather than a single institution, a semi-private blockchain ) has the character of At this time, if there are 5 block producers, the authenticity of the transactions included in the block can be confirmed by 3 (a majority) consensus, which is called DPOS (Delegated Proof of Stake). It can be referred to as a consensus algorithm.

In other words, Block Producers who are allowed to participate create blocks with transaction details, are given the authority to verify them, and obtain a consensus of the majority of Block Producers B for the blocks containing the transaction details. When (Consensus) is made, a block containing the transaction details is created on the blockchain network.

As described above, through the Semi-Private Blockchain, first, the nature of the subject, the authority that the subject has, and the clear definition and traceability of the contents of actions such as harvesting and disposal that can be performed with that authority Second, hemp seeds, embryos, outposts, flowers, by-products, oil, waste, finished cosmetics, etc. can be flexibly and consistently changed the history of hemp (HEMP) management objects that change in various forms depending on the distribution stage. can be managed in an appropriate way.

In other words, it is not a completely permissioned blockchain operated by a single node or entity, but reliability and security for data in the distribution history shared through the blockchain network in that it is operated with several stakeholders participating as block generation nodes. In addition to guaranteeing stability and integrity, it has the advantage of being able to respond flexibly and quickly to each situation through agreement between a small number of block generating nodes compared to public blockchains in the event of a major update of the blockchain network. .

9 to 11 are reference diagrams for explaining a QR code image matched to an NFT token according to an embodiment of the present invention.

12 to 15 are reference diagrams for explaining distribution history information to be stored in an NFT token according to an embodiment of the present invention.

As shown in FIG. 6, the server 10, the distribution history recording permission terminal 20, and the token issuance management terminal 30 according to this embodiment are connected through a network and can transmit and receive data between them. Here, the network may include, for example, wireless Internet such as wireless fidelity (Wi-Fi), mobile Internet such as wireless broadband internet (WiBro) or world interoperability for m2microwave access (WiMAX), global system for mobile communication (GSM), or CDMA. 2G mobile networks such as code division multiple access (code division multiple access), 3G mobile networks such as wideband code division multiple access (WCDMA) or CDMA2000, and 3.5G mobile networks such as high speed downlink packet access (HSDPA) or high speed uplink packet access (HSUPA). It may be implemented in various networks such as a 4G mobile communication network such as a communication network, a long term evolution (LTE) network, or an LTE-Advanced network, and a 5G mobile communication network.

The distribution history recording permission terminal 20 and the token issuance management terminal 30 are not particularly limited as long as they have a communication function connected to the server 10 and a display function capable of outputting images or text. For example, each terminal is an IoT device, a desktop computer, a laptop computer, a tablet PC, a wireless phone, a mobile phone, and a smart phone. ), smart watch, smart glass, eBook reader, PMP (portable multimedia player), portable game device, navigation device, digital camera, DMB (digital multimedia broadcasting) player, digital audio recorder, digital audio player, digital picture recorder, digital picture player, digital video recorder, digital video player video player), etc., but is not limited thereto.

According to an embodiment of the present invention, the distribution history system using NFT tokens is a blockchain network formed by a distribution history recording permission terminal 20, a server 10, a token issuance management terminal 30, and at least one participating node. includes

More specifically, the distribution history record permission terminal 20 for transmitting the distribution history data related to the distribution history management object to the blockchain network and / or the server 10, the distribution history data or the metadata address where the distribution history data is stored. The server 10 that generates and propagates a transaction including information to the blockchain network and requests the issuance of the Nth (#n) NFT token to the token issuance management terminal 30, distribution history data propagated to the blockchain network, or A token issuance management terminal and at least one participating node that generates a transaction issuing the Nth (#n) NFT token containing metadata address information as unique information and propagates it to the blockchain network uses a preset consensus algorithm and a block chain network that generates a block including at least one transaction information.

The distribution history recording permission terminal 20 transmits distribution history data related to a distribution history management object to the server 10 . At this time, it has the authority to transmit the distribution history data related to the distribution history management object to the blockchain network and / or the server 10.

9 and 12 to 15, the distribution history data recorded by the distribution history recording permission terminal 20 includes cultivation conditions, cultivation history information, extraction and processing information (raw material conversion history information, disposal information, etc.), sales/ Export information (purchaser identification, refund, return information, etc.), quality certification information (CBD and THC ingredient content information, pesticide use information, etc.), processed product information (cosmetics, beverages, flowers, cigarettes, undiluted solutions, etc.), transfer information ( It may include release history information, acquisition and transfer certification information, receipt confirmation information, etc.), compliance information (licensing and permission information, etc.), etc.

At this time, the distribution history recording permission terminal 20 has a recording authority and a recording condition set so that only distribution history data related to a specific distribution history management object can be recorded. In case of omission of records, the record authority may be revoked according to the set cancellation conditions.

For example, referring to FIG. 8 , a hemp (HEMP) cultivation farm among a plurality of actors requiring hemp distribution history management will be described as an example. The distribution history recording permission terminal 20 (hemp cultivation farm terminal) may record distribution history data related to hemp cultivation. At this time, the schedule record conditions requested by the token issuance management terminal 30 (regulatory authority or government agency terminal) (recording time: 10:00 am every day, record items: list of visitors, number of visits, record items for the number of seeds planted) If not satisfied, the token issuance management terminal 30 may cancel the recording authority of the distribution history recording permission terminal 20 . On the other hand, the terminal for which the recording right has been revoked may be recognized as having the license related to cannabis cultivation revoked by the actual regulatory supervisory authority.

The server 10 means a server 10 having a blockchain interface, and the server 10 transfers the distribution history data transmitted by the distribution history recording permission terminal 20 and the metadata address of the distribution history data to a blockchain network. send to Meanwhile, the server 10 may store distribution history data in a history management database (not shown) or may also be stored on an IPFS system (distributed file system, not shown). The server 10 transmits a command for permitting or canceling the recording authority of the distribution history recording permission terminal 20 from the token issuance permission terminal (a terminal linked to a government agency or a regulatory supervisory authority) to the distribution history recording permission terminal 20. can be conveyed

At this time, the server 10 generates a transaction including distribution history data or metadata address information in which distribution history data is stored, propagates the transaction to the blockchain network, and distributes it to the token issuance management terminal 30. It is possible to request the issuance of the Nth (#n) NFT token containing information. On the other hand, if the form of the distribution history management object is changed, all distribution history data or metadata address information stored in the Nth (#n) NFT token of the form before the change is further included, and the provision regarding the changed form of the distribution history management object You can create a transaction that issues N+1 (#n) NFT tokens.

Hereinafter, the Nth NFT token and the N+1st NFT token will be described. For example, hemp management objects are derived and changed in countless forms such as seeds, outposts, cultured tissues, clones, stems, and CBD in the distribution stage. That is, since hemp management objects have various forms, it is necessary to thoroughly manage the change form and change history by accumulating the history for each object. For example, the subject matter is the 1st NFT token related to the outpost, the 2nd NFT token related to harvest, the 3rd NFT token related to waste, the 4th NFT token related to CBD extract, and the 5th related to intermediate processing. NFT Token ~ .... ~ The Nth NFT token related to the final product, etc. It started from the same outpost, but as each object changes, separate 1st to Nth NFT tokens are issued sequentially for each object, and the object history can be recorded. On the other hand, the newly issued NFT token with a change in the object includes all of the history of the previously issued object NFT token, so that the entire change history of the last object can be cumulatively confirmed and managed as one token.

In other words, NFT tokens for each object manufactured/produced/processed from the same cultivated hemp can be merged or separated as their form changes into subdivision containers and oil extracts of crops such as outposts, flowers, and leaves during the distribution process of the management object. In the case of merging or separation, all of the history of the previous stage is preserved in the merged or separated result token without loss, so that the subsequently generated NFT token can manage and preserve all the history of the previous object.

In another embodiment of the present invention, when the distribution history recording permission terminal 20 transmits distribution history update data for updating the existing distribution history data recorded in the Nth (#n) NFT token issued, the server 10 ) includes all distribution history data or metadata address information stored in the issued Nth (#n) NFT token, but further includes distribution history update data or updated metadata address information as unique information. It is possible to request the token issuance management terminal 30 to generate (#n+1) NFT tokens and incinerate the Nth (#n) NFT token.

Hereinafter, the Nth NFT token and the N+1st NFT token will be described. For example, in the 4th (#1) NFT token related to CBD extract, the active ingredient (CBD) content was recorded as 0.002% and the harmful ingredient (THC) content as 0.4%, but the harmful ingredient (THC) When the distribution history update data with the content corrected to 0.3% is transmitted, the 4th (#2) containing all the history update data including all the history data recorded in the existing 4th (#1) NFT token ) NFT tokens are created, and the previously generated 4th (#1) NFT tokens can be incinerated.

Through this, by thoroughly managing the renewal history for the same object with a single NFT token, it is possible to increase the efficiency of management of history changes for the same object.

On the other hand, if the content modified by the update data is an update request due to an incorrect entry in the distribution history data, penalty points that are the basis for canceling the recording right may be given to the distribution history recording permission terminal 20, but token issuance In case the updated data is entered due to the occurrence of a history data item to be updated or added according to the request for additional reporting requirements from the permission terminal (government agency, regulatory supervision agency) or the integrated narcotics management system, etc., it is not grounds for canceling the record authority.

At this time, the token issuance management terminal 30 generates a transaction requesting generation of the Nth (#n+1) NFT token, and after the Nth (#n+1) NFT token is issued, the existing distribution A transaction that burns the Nth (#n) NFT token in which the history data is stored can be created and propagated to the blockchain network.

In another embodiment of the present invention, referring to FIGS. 9 to 11, the issued Nth (#n) and N+1th (#n) NFT tokens further include token serial number information, and the token series The number is encrypted and recorded on the blockchain network, and the encrypted token serial number can be converted into tag information using QR code or RFID and used.

The token issuance management terminal 30 generates a transaction for issuing the Nth (#n) NFT token containing the distribution history data or metadata address information propagated to the blockchain network as unique information and propagates it to the blockchain network. do.

The token issuance management terminal 30 may distribute and manage smart contracts on a blockchain network for the issuance and management of NFT tokens for tracking objects that vary in form depending on the distribution stage.

Specifically, the token issuance management terminal 30 performs NFT token generation (minting), NFT token history update, NFT token transfer (transfer), NFT token incineration (burn), NFT token offer (offer), NFT token offer cancellation, NFT token A smart contract set for merging and splitting NFT tokens is distributed according to the agreement of a majority of block generating nodes, and NFT tokens can be issued and managed using the generated smart contract address.

In other words, the smart contract distributed by the token issuance management terminal 30 has the nature of an NFT token database in which NFT tokens related to the distribution history of the object are stored, and the token issuance management terminal 30 stores the distribution history and distribution history in the distributed smart contract address. You can store and manage related NFT tokens.

At this time, when an ownership transfer execution command is received from the token issuance management terminal 30 related to the generation of the Nth (#n) NFT token based on the smart contract of the blockchain network, the ownership transfer command of the NFT token may be executed. there is.

On the other hand, an ownership transfer execution command for the Nth (#n) NFT token is received from all of the token issuance management terminal 30 and the distribution history recording permission terminal 20 related to the generation of the Nth (#n) NFT token. If so, MSIG (Multi Signature) can be set so that the ownership transfer command of the NFT token can be executed. Through this, the transfer of ownership of the NFT token can be carried out through the electronic signatures of all terminals involved in recording the NFT token.

7 is a flowchart illustrating a method for managing distribution history using NFT tokens by the distribution history system using NFT tokens according to an embodiment of the present invention. Each step of the method according to FIG. 7 may be performed on a block chain network interlocked with a computer network, and each step is described with reference to FIGS. 5 and 7 as follows.

First, (a) at least one distribution history recording permission terminal 20 transmits distribution history data related to a distribution history management object to the server 10 (S100).

Thereafter, (b) the server 10 stores the distribution history data in the object history management database, creates a transaction including distribution history data or metadata address information in which the distribution history data is stored, propagates it to the blockchain network, and tokens The issuance management terminal 30 is requested to issue an NFT token corresponding to the distribution history management object (S200).

Subsequently, (c) the token issuance management terminal 30 creates a transaction for issuing the Nth (#n) NFT token containing the distribution history data or metadata address information propagated to the blockchain network as unique information to block It propagates to the chain network (S300).

At this time, in step (c), if it is confirmed that the shape of the distribution history management object has changed, all distribution history data or metadata address information stored in the Nth (#n) NFT token of the form before the change is further included. It is possible to create a transaction for issuing the N+1th (#n) NFT token for the distribution history management object of the form.

At this time, the Nth (#n) and N+1st (#n) NFT tokens to be issued may further include token serial number information. Meanwhile, the token serial number is encrypted and recorded in the blockchain network, and the encrypted token serial number can be converted into tag information using a QR code or RFID and used.

Finally (d) at least one participating node generates a block including at least one transaction information using a consensus algorithm preset in the blockchain network and records it in the blockchain network (S400).

On the other hand, in another embodiment of the present invention, in step (a), the distribution history recording permission terminal 20 updates the distribution history to update the existing distribution history data recorded in the Nth (#n) NFT token issued. Data can be transmitted, in this case, in step (b), the server 10 includes all distribution history data or metadata address information stored in the issued Nth (#n) NFT token, but distribution history update data or It is possible to generate an Nth (#n+1) NFT token further including the updated metadata address information as unique information and to request the token issuance management terminal 30 to incinerate the Nth (#n) NFT token. there is.
