Orchids are a representative example of flowering plants. Orchids are monocotyledonous plants that are loved by many people for their beautiful and fragrant flowers, and are traded at various prices ranging from tens of thousands of won to tens of millions of won, depending on the variety and level of cultivation.

In the past, in order to purchase flowers such as orchids, people directly visited orchids, orchids, orchids, and orchid stores to see the condition of orchids with their own eyes. According to the change, people are purchasing ornamental flowers such as orchids in a non-face-to-face manner using online shopping malls or social networking services (SNS).

In this case, the buyer makes a purchase by looking at a picture or the like posted by the seller for sale. However, it is not only difficult to provide sufficient information on the flowers such as orchids sold only with photos, but also due to optical illusions or exaggerated packaging in terms of color, size, balance, etc., it is difficult to convey accurate information about the product to the buyer. Buyers are likely to make the wrong purchase. In addition, because flowers such as orchids may look different depending on the viewpoint of viewing the picture and the real thing, the buyer may think that he has received a product different from the product he purchased, which may cause a dispute between the buyer and the seller.

Therefore, there is a need for a system that can provide buyers with sufficient information about plants such as orchids that are sold non-face-to-face, and can guarantee that accurate transactions have been made to both buyers and sellers without any dispute after purchase.

In more detail, the token management unit 110 may register and manage the data of the issued first token, including plant state information, ownership information of the plant, and first smart contract information, in a management list, and may manage the purchaser's terminal ( 300) may check the data of the first token registered in the management list. That is, the purchaser's terminal 300 may receive data of the first token.

The first token may be a non-fungible token (NFT) having a unique identification value to be distinguished from other tokens. A non-fungible token may be a non-fungible token because it can be distinguished from other tokens by inputting a unique identification value.

In the blockchain, digital assets are managed in the form of tokens, which are applications implemented as smart contracts. In this way, tokenizing and managing digital assets in the blockchain provides advantages such as immutability, quick access, or high liquidity. have Tokens are classified into fungible tokens and non-fungible tokens.

Unlike fungible tokens that can be exchanged 1:1 with other tokens of the same type, non-fungible tokens can be issued with plant status information or plant owner information, and can be distinguished from other tokens by entering a unique identification value. Since it is non-substitutable, the present invention can prevent forgery and falsification of plant transaction details in a digital environment where copying is easy by using non-fungible tokens, and thus has an effect of improving reliability of transactions.

The non-fungible token may include property values that conform to the protocol that the non-fungible token follows, including a token identifier (tokenID), a token integrated resource identifier (tokenURI), and a token owner (tokenOwner).

The token identifier (tokenID) may include a unique number of the token. In one embodiment, the unique number of an already issued token cannot be used. Also, the unique number of burned tokens cannot be used again.

The token URI may include a value expressing the location of a file containing token information as a Uniform Resource Identifier (URI). The information of the token may include, but is not limited to, the properties of the token, the location where the original file of the digital work connected to the NFT token is stored, and the like. Here, the unified resource identifier (URI) may mean a unique address representing a resource on the Internet. In one embodiment, the token integrated resource identifier may include a JSON (JavaScript Object Notation) type file.

A tokenOwner may include information about a person who owns a corresponding token. For example, information about who owns a token may include the token owner's blockchain wallet address.

The token management unit 110 may collect data of the non-fungible token by searching for a storage where the first token, which is a non-fungible token, is stored. The non-fungible token may include plant state information, plant ownership information, and first smart contract information.

In one embodiment, a repository where non-fungible tokens are stored may include, but is not limited to, a non-fungible token marketplace for trading non-fungible tokens. The repository where non-fungible tokens are stored may include a non-fungible token platform for the purpose of issuing and storing non-fungible tokens. For example, non-fungible token marketplaces may include, but are not limited to, marketplaces such as OpenSea, Rarible, Foundation, Niftygateway, SuperRare, KnownOrigin, MakersPlace, Async, Paras, NBA TopShot, etc. It can be added or excluded if it is opened or closed.

The non-fungible token marketplace and the non-fungible token platform may include a smart contract for storing non-fungible tokens, and the smart contract includes plant state information, plant ownership information, and first smart contract information issued by It may be the first smart contract.

In other words, the token management unit 110 searches for the first smart contract including the transaction information of the issued non-fungible token including the plant state information, plant ownership information, and first smart contract information to search for the first non-fungible token, Data of 1 token can be collected.

The token management unit 110 may collect data of the first token by inquiring about issuance and transaction details of the first token by utilizing a blockchain standard interface used for issuance of each first token, which is a non-fungible token. Data of the first token may be stored in a token database.

The non-fungible token, which is the first token according to the present invention, may be issued and traded using ERC (ethereum request for comments)-721, which is a standard interface related to the Ethereum blockchain, but is not limited thereto. In another embodiment, NFTs may be issued and traded using the Ethereum standard interface ERC-1155, and may be issued using various blockchain protocols other than Ethereum. Through the issuance of non-fungible tokens, non-fungible tokens are created so that the blocks constituting the smart contract can be added to the chain.

The data of the first token may include at least one of a token identifier (tokenID), a token integrated resource identifier (tokenURI), and a token owner (tokenOwner). Token information can be obtained using the address included in the token integrated resource identifier.

The first token may include plant state information provided from the smart pot 200 in which the plant is planted, ownership information of the plant, and first smart contract information.

The plant state information may be information about plants planted in the smart pot 200 . Plant state information may be collected from the smart pot 200 and provided. The plant state information may include rotatable 3D atypical data of the plant, which will be described later. The plant state information may include at least one of length data for each part obtained by measuring a predetermined length for each part. In one example, the length data for each part may include one or more of plant height, leaf width, and leaf length. In addition, plant state information may further include a plant variety, a plant disease state, a plant root state, and the like.

Ownership information of the plant may be information about the owner of the plant. Ownership information of plants may be provided from the smart pot 200 . Ownership information of the plant may include one or more of the owner's name, contact information, address, desired selling price of the plant, type of virtual asset desired for transaction, and blockchain wallet address.

The first smart contract may be a smart contract in which a first coin connected to a plant is issued and a transaction is made. In general, in the field of blockchain technology, smart contract is a transaction technology implemented using blockchain to conclude and fulfill various types of contracts such as financial transactions, non-transactional contracts, and notarization in a p2p (peer to peer) method without an intermediary. it means. The first smart contract information may be information about this smart contract.

The first token is issued by being divided into one or more split tokens, and each of the split tokens may include different state information, ownership information of the plant, and first smart contract information. That is, the first token may be issued using various block chain protocols as described above, and at this time, it may be divided into one or more split tokens and issued, and the buyer's terminal 300 may divide them and purchase them. Each split token can have each split ownership.

In the case of plants such as orchids, the price is high enough to cost several tens of millions of won depending on the variety and level of cultivation, so it is not easy for ordinary buyers to purchase them. However, in the present invention, since these plants are sold with a plurality of split tokens having split ownership, general buyers can easily divide and purchase them, and if the price of the purchased orchid rises, they can resell it to earn profits It works.

The monitoring unit 120 may monitor whether or not the purchaser's terminal 300 agrees to the plant transaction. That is, the monitoring unit 120 monitors the first smart contract using the first smart contract information of the first token registered in the management list, and the buyer's terminal 300 agrees to the terms of the first smart contract. , that is, can be monitored to see if it is met.

The monitoring unit 120 may monitor the first smart contract in which the first token is issued by using the first smart contract information included in the data of the first token.

More specifically, the monitoring unit 120 may monitor the first smart contract in which the first token is issued by using data of the first token, and obtain a first transaction from the first smart contract. The monitoring unit 120 may monitor the first smart contract in which the first token is issued by using the first smart contract information included in the data of the first token. The monitoring unit 120 may identify the first token from the first smart contract using the token identifier included in data of the first token, and inquire information about the first transaction. The first transaction of the first token may include transaction information of the first token. Transaction information of the first token may include a seller, a buyer, and transaction revenue (ie, the number of cryptocurrencies paid for the transaction) of the plant corresponding to the first token.

The transaction history management unit 130 performs a first transaction that changes the owner of the plant to the buyer in the ownership information of the plant corresponding to the first token as the contract terms of the first smart contract are agreed upon by the terminal 300 of the buyer. An algorithm may be implemented based on a block chain to be included in the first smart contract. That is, when a buyer purchases a plant from a seller, the ownership information of the plant in the first transaction is changed from the owner of the existing plant to the current owner of the plant, that is, the buyer, and the first transaction is included in the first smart contract. Algorithms can be implemented based on chains.

The transaction history management unit 130 manages the registration and transaction of ownership information of the first token based on blockchain technology, and generates a token designated in advance to be paid or paid upon registration, verification, inquiry, transaction and transfer of ownership information, and Implementing an algorithm based on a blockchain so that the generated utility token can be distributed so that the created token can be registered and moved, distributed, or transferred, and the first token is managed by the implemented algorithm. It can have the characteristics of a blockchain platform. In one example, the algorithm encrypts multiple transaction records and connects them like a chain to prevent forgery and tampering and manages data in a decentralized distributed storage method, including the Lightning Network, Plasma, Plasma Cash, Side Chain, Double Chain, It can be one or more of the interchains.

According to the above agreement, the cost to be paid when performing the first transaction may be paid in at least one or more replaceable tokens predetermined in the first smart contract.

More specifically, the transaction history management unit 130 changes the owner of the plant to the buyer in the ownership information of the plant corresponding to the first token when the contract terms of the first smart contract are agreed upon by the consent, that is, the terminal 300 of the buyer. The cost to be paid at this time can be managed so that it is paid with at least one or more replaceable tokens pre-determined in the first smart contract. In this case, the at least one substitutable token predetermined in the first smart contract may be a virtual asset that the seller wishes to trade or a substitutable token predetermined in the blockchain platform.

In this way, when the seller trades with the virtual asset that the seller wishes to trade, the seller can increase transaction satisfaction. In addition, since the transaction is made with a fungible token rather than a non-fungible token, it is possible to solve the instability of profits due to rapid market price fluctuations when trading with a conventional non-fungible token.

As described above, the blockchain-based plant trading system 10 according to an embodiment of the present invention conducts transactions based on the blockchain when trading plants, thereby blocking the possibility of forgery and falsification of transactions that may occur during non-face-to-face transactions. There is an effect of improving the reliability of the transaction.

In particular, in the case of orchids, even if a buyer makes a purchase decision after seeing a photo of a plant during a non-face-to-face transaction, the plant may be distorted and expressed by the photo, and the seller exchanges it for a low-grade orchid similar to the orchid that the buyer has decided to purchase to the buyer. There is a problem that it is difficult to maintain the reliability of the transaction, such as delivery. However, in the case of using the blockchain-based plant trading system 10 according to the present invention, the reliability of the information can be guaranteed by storing various history information of plants and transactions based on the blockchain, and by using this, the plant transaction can be performed. By proceeding, there is an effect of preventing forgery and falsification of the transaction.

In addition, in one embodiment, the blockchain-based plant trading system 10 according to the present invention may further include a real transaction management unit (not shown).

When a transaction is completed between the seller and the buyer and the first transaction for changing the owner of the plant to the buyer in the ownership information is included in the first smart contract, the real transaction management unit and the owner of the real transaction request received from the buyer's terminal 300 The owners of the first transaction included in 1 token are compared, and if they match, the actual transaction of the plant can be carried out by delivering the real plant to the buyer. On the other hand, if the transaction request from the buyer's terminal 300 does not exist even though the transaction between the seller and the buyer is completed and the first transaction for changing the owner of the plant to the buyer in the ownership information is included in the first smart contract, The physical transaction management unit can be carried out so that the consignment sale of the plant is carried out by the buyer while the seller continues to manage the real thing of the traded plant.

Since orchids are difficult to grow, buyers had many difficulties, such as finding a separate grower to manage the orchids even after purchasing the orchids, renting a shared orchid room, and hiring separate management personnel. In addition, even if such a transaction was concluded, problems such as disappearance of the egg room entrusted with management or denial of ownership of the orchid entrusted by the purchaser in the egg room could occur. However, the blockchain-based plant trading system 10 according to the present invention trades only the ownership of the plant, not the real thing, between the seller and the buyer during the transaction, and the plant management is easy to proceed with the consignment transaction previously performed by the seller, Since the information on the contents of this consignment transaction (ownership transaction information, actual non-delivery history information, etc.) is managed based on the blockchain, it is effective in preventing disputes over the contents of the consignment transaction.

FIG. 2 is a conceptual diagram for explaining the smart flower pot shown in FIG. 1 , and FIG. 3 is a perspective view for explaining the smart flower pot of FIG. 2 .

Referring to FIGS. 2 and 3 , the smart flower pot 200 may include a VR photographing unit 210 , a sensor unit 220 and a control unit 230 .

The VR photographing unit 210 may generate photographing data by photographing the plants planted in the smart flowerpot 200 .

The VR photographing unit 210 may photograph a plant planted inside the smart flowerpot 200 and generate rotatable 3D irregular data for the photographed plant.

Unstructured data refers to data that is not standardized due to its complex shape and structure, and typical unstructured data includes video files, audio files, photos, and documents.

The VR photographing unit 210 may include one or more cameras 212 for photographing plants.

The VR photographing unit 210 uses the camera 212 to continuously stream all 360-degree images of the plants in the smart flower pot 200 as images, and captures 3D unstructured data for the model of the plant instantaneously by taking a screen shot. can be automatically generated.

The VR photographing unit 210 may automatically generate 3D atypical data that can be observed by zooming in or zooming out a specific area of a plant in the purchaser's terminal 300 or by rotating it in any one direction of 390 degrees.

The VR photographing unit 210 may further include a measurement module 211 .

The measurement module 211 may measure the length of each predetermined part of the plant photographed through the camera 212 . The measurement module 211 may measure the external appearance of a plant exposed to the outside using a laser. The measurement module 211 may measure the external shape of a root, etc. of a plant buried in soil using ultrasonic waves.

The measuring module 211 may generate length data for each part obtained by measuring the length for each predetermined part of the plant. Length data for each part may be included in 3D irregular data.

Photos and simple videos can be distorted or look different depending on the viewing point.

In particular, plants such as orchids require accurate observation when trading because their prices vary greatly depending on height, width of leaves, length of mouth, lesions, shape and length of roots, etc. However, in the case of non-face-to-face trading of plants as in the prior art, it is difficult to accurately observe plants with only photos or simple images, and there is a problem that it is difficult for buyers to accurately evaluate. On the other hand, since the present invention provides rotatable 3D unstructured data for traded plants, buyers can more accurately observe plants by rotating, zooming in, or zooming out. In addition, by providing length data for each part, such as the length of the leaf to be observed and the width of the leaf, there is an effect of lowering the possibility that the buyer may make an incorrect appraisal due to distortion or difference in accumulation of conventional photos or images.

In addition, since 3D unstructured data is stored based on the block chain, it is possible to block data modification by malicious purposes by sellers or related parties, thereby improving reliability of 3D unstructured data.

All or part of the 3D unstructured data may be selectively included in the state information according to the size of the data. When only a part is selectively included, the state information may further include first Internet address information where an original file of 3D unstructured data is stored. The first Internet address information may be address information generated through an InterPlanetary File System (IPFS).

The first Internet address information may be disclosed and accessible from the purchaser's terminal 300 .

In this case, there is an effect of reducing the problem of deterioration of transmission efficiency and system efficiency due to excessive data being included in the first token.

The smart flower pot 200 may further include a sensor unit 220 and a control unit 230.

It can have the characteristics of a blockchain platform. In one example, the algorithm encrypts multiple transaction records and connects them like a chain to prevent forgery and tampering and manages data in a decentralized distributed storage method, including the Lightning Network, Plasma, Plasma Cash, Side Chain, Double Chain, It can be one or more of the interchains.

The blockchain-based plant trading system 10 according to the above can improve the reliability of transactions by blocking the possibility of forgery and falsification of transactions that may occur in non-face-to-face transactions by conducting transactions based on blockchain when trading know-how It works.

In particular, since orchids are very difficult to grow, know-how is very important in growing orchids. In the case of using the blockchain-based plant trading system 10 according to the present invention, the reliability of the information can be guaranteed by storing the know-how based on the block chain, and by using this, the know-how transaction can be performed to prevent forgery and falsification of the transaction. There are possible effects.

On the other hand, since a plant such as an orchid has a very large price difference according to appraisal, it is necessary to determine whether to purchase it by accurate appraisal. However, since appraisal of orchids is rather difficult for general buyers, appraisal by professional appraisers is required.

In order to solve this problem, the blockchain-based plant trading system 10 according to the present invention may further include an evaluation information collection unit 140 to appraise plants such as orchids and secure reliability of the appraisal results.

4 is a conceptual diagram for explaining a configuration including an evaluation information collection unit according to an embodiment of the present invention.

The evaluation information collection unit 140 may provide status information to the appraiser's terminal 400 and collect plant appraisal information provided from the appraiser's terminal 400 based on the status information. In this case, the first token may further include plant appraisal information.

The buyer's terminal 300 may obtain plant appraisal information included in the data of the first token.

That is, an appraiser with professional appraisal knowledge or appraisal ability for a corresponding plant analyzes state information provided to the appraiser's terminal 400 . At this time, the state information includes rotatable 3D atypical data and length data for each part of the plant. Therefore, through the appraiser's terminal 400, the appraiser can observe the plant in all directions by rotating it 360 degrees, and observe the details of the plant by zooming in or zooming out a specific area. By checking the star length data, the size, width, and length of the actual plant can be confirmed regardless of the distortion of the plant according to the video or photo. ) may be provided to the evaluation information collection unit 140 as plant appraisal information.

For example, plant appraisal information for orchids may include information on growth evaluation, year evaluation, leaf longevity evaluation, leaf width evaluation, leaf length evaluation, leaf growth and lesions, root evaluation, and the like, and a price including these Calculations may be included.

In addition, plant appraisal information may be provided to the buyer's terminal 300 through the evaluation information collection unit 140 . In this case, the buyer can refer to the plant appraisal information evaluated by a professional appraiser to make an accurate evaluation of the plant he/she wants to purchase, thereby reducing the time required for plant evaluation and avoiding the wrong purchase due to incorrect evaluation. may lower the possibility of
