Here, each module may be generated as a combination of at least one or more executable instructions, and the modules may be interconnected to operate.

In addition, the company-side and user-side encrypted electronic wallets 110 and 130 have ID profile information including a wallet address, user identification information (IDE), and the like, which are verified with biometric information or password. To this end, each user-side node 120 must generate unique identification information (IDE) for each user according to an identity verification procedure (for example, a KYC (Know Your Client) process). For example, an identification information (IDE) that is uniquely given to a specific user and is not duplicated is generated through an identification card or biometric identification process that can confirm the user's identity, and is stored in the recording medium 200 of the user-side node 120. It must be stored or user-inputable. An identification procedure such as KYC is a known technique, and since user identification information (IDE) can be generated through various methods, a detailed description of identification is omitted in this specification.

In addition, the company-side and user-side cryptographic electronic wallets (110, 130) can generate a hash value for each transaction specification whenever a transaction related to ownership of utility tokens for tangible and intangible assets and transaction coins occurs, and the transaction specification is a preset number. When you reach, you can create a block. Specifically, the company-side and user-side encrypted electronic wallets 110 and 130 generate a hash value corresponding to the transaction specification each time a transaction occurs, and as 1,000-1,800 transaction specifications are generated, the hash value for each transaction specification is generated. After calculating a MerkleTree hash value as an input value, a block hash value can be generated based on this to generate a block. Accordingly, the block may include a block header including a previous block hash value, a Merckley hash value, a software version, a block creation time, a proof-of-work answer value, etc., and a black hash value. Based on value, they can be interconnected to form a blockchain.

In order to manage the company-side and user-side encrypted electronic wallets 110 and 130 that perform the functions as described above, the tangible and intangible asset transaction system 100 and the user-side node 120 have a communication function, an information recording function, and an application (e.g., As a device that may have a communication circuit, a processor, etc. that can execute an encryption electronic wallet), for example, a smartphone, a PC, a tablet, a server, etc. may be exemplified, but the present invention is not limited thereto.

The issuing server 300 uses the value of the tangible and intangible assets held in the company to issue utility tokens for internal tangible and intangible assets transaction, utility tokens for internal tangible and intangible assets, and coins for exchange transactions having a preset exchange rate on the blockchain network. I can. Specifically, the issuing server 300 issuing utility tokens for internal transaction of tangible and intangible assets to be issued based on information on tangible and intangible assets managed by the tangible and intangible asset management server 320, for example, a price set by an authorized appraisal agency or organization. After setting the number and price, the utility token for tangible and intangible assets that the company owns is recorded in the company's encrypted electronic wallet (110) and issued on the blockchain network. The corresponding exchange transaction coin can be recorded in the company's encrypted electronic wallet 110 through ICO and issued on the blockchain network.

For example, if the value of the company's tangible and intangible assets is 800 million and the utility token for internal transaction of one tangible and intangible asset is 40,000 won, the issuing server 300 issues 20,000 utility tokens for internal transaction of tangible and intangible assets, It is possible to issue coins for trading more than the number of issued utility tokens for tangible and intangible assets, for example, 1.2 to 1.5 times of coins for exchanges announced in advance. Accordingly, the exchange ratio between the utility token for tangible and intangible assets and the transaction coin can be set to 1.2 to 1.5.

On the other hand, the issued utility tokens for tangible and intangible assets are used for an auction service provided by the tangible and intangible asset trading system 100, and coins for exchange transactions are used by users who hold the user-side encrypted electronic wallet 130, like other cryptocurrencies. It may be registered in the coin exchange 140 in order to be able to be traded.

The tangible and intangible asset purchase server 310 responds to the value of the purchased tangible and intangible asset after purchasing the tangible and intangible asset as a utility token for internal transaction of tangible and intangible assets corresponding to cash or value when a sale request for tangible and intangible assets is received from an arbitrary owner. Utility tokens for internal transaction of tangible and intangible assets can be issued on the blockchain network. Specifically, the tangible and intangible asset purchase server 310 determines the number of tangible and intangible asset internal transaction utility tokens to be issued based on the current value of the tangible and intangible asset internal transaction utility token and the value of the purchased tangible and intangible asset, and The owner of the transaction utility token may be set as a company or a user to sell tangible and intangible assets, recorded in the company-side encrypted electronic wallet 110 or the user-side encrypted electronic wallet 130, and issued on the blockchain network.

In addition, the tangible and intangible asset purchase server 310 may issue a coin for exchange transaction corresponding to the issued utility token for internal tangible and intangible asset transaction. Specifically, the tangible and intangible asset purchase server 310 determines the number of coins for exchange transactions by applying an exchange rate to the number of utility tokens for internal tangible and intangible assets transaction issued according to the purchase of tangible and intangible assets, and coin for exchange transaction corresponding to the determined number. Can be published on the blockchain network.

The tangible and intangible asset management server 320 may manage information on tangible and intangible assets held by the company. Specifically, the tangible and intangible asset management server 320 includes digital information on tangible and intangible assets held by the company, such as value, the number of utility tokens for internal transaction of tangible and intangible assets issued when purchasing tangible and intangible assets, owner information, auction history, authenticity authentication You can manage information, etc.

The auction service providing server 330 may provide an auction service for tangible and intangible assets held by the company. Specifically, the auction service providing server 330 may display information on tangible and intangible assets owned by the company and the number of utility tokens for internal transaction of tangible and intangible assets on a web page notifying the auction start information including the set auction start price.

The auction service providing server 330 according to the embodiment of the present invention stores the bid price inside the tangible and intangible asset through interworking between the company-side encrypted electronic wallet 110 and the user-side encrypted electronic wallet 130 managed by the tangible and intangible asset trading system 100 It can be received as a utility token for trading. Specifically, as the exchange transaction coin for the bid price is transferred from the user-side encrypted electronic wallet 130 to the address of the company-side encrypted electronic wallet 110 according to the manipulation of the user (eg, auction participant), the company-side encrypted electronic wallet ( The mutual exchange module 204 of 110) may convert the remitted transaction coin into a utility token for internal transaction of tangible and intangible assets according to an exchange rate, and provide it to the auction service providing server 330. Accordingly, the auction service providing server 330 may set the converted utility token for internal transaction of tangible and intangible assets as the user's bid price.

On the other hand, in the case of remittance of other cryptocurrencies from the user-side encrypted electronic wallet 130 in the user-side node 120 to the address of the company-side encrypted electronic wallet 110 at a bid price, the mutual exchange module 204 of the company-side encrypted electronic wallet 110 ) Buys a coin for transaction at the coin exchange 140 using the remitted cryptocurrency, converts it into a utility token for internal transaction of tangible and intangible assets on the company side according to the exchange rate, and provides it to the auction service providing server 330 have. Accordingly, the auction service providing server 330 may set a utility token for internal transaction of tangible and intangible assets on the side of the company that has been exchanged as the user's bid price.

In addition, as the tangible and intangible asset is a successful bid to a random user (hereinafter, referred to as a'successful bidder'), the auction service providing server 330 stores utility tokens for tangible and intangible assets that the other bidders excluding the successful bidder. ) Can be used to send money. Specifically, the auction service providing server 330 is a cryptocurrency used when bidding by using the mutual exchange module 204 in the company's encrypted electronic wallet 110 for the utility token for internal transaction of tangible and intangible assets on the company side that bidders other than the successful bidders bid. Alternatively, the exchange may be exchanged for coins or cash, and then remitted using the address of the user-side encrypted electronic wallet 130 of the bidder.

The asset sale server 340 operates as the ownership of the tangible and intangible asset is transferred to the successful bidder after the tangible and intangible asset is a successful bidder, and may sell utility tokens for internal transaction of tangible and intangible assets set as the auction start price and coins for exchange transaction. Specifically, the asset sale server 340 generates a transaction for deleting the utility token for tangible and intangible assets set as the auction starting price from the company-side encrypted electronic wallet 110 to generate a utility token for internal transaction of tangible and intangible assets corresponding to the auction starting price. In addition to deletion, some of the utility tokens for internal transaction of tangible and intangible assets remaining after deletion, such as 40% to 60% of the remaining utility tokens for internal transaction of tangible and intangible assets, are used by the mutual exchange module 204 in the company's encrypted electronic wallet 110 Thus, after converting into a transaction coin, a transaction to sell it can be generated and the exchange transaction coin can be sold.

The successful bid item processing server 350 is to provide a service for delivering the item to the successful bidder when the tangible and intangible asset is an item, and an interface for selecting a method of handling the successful bid item for the item, for example, storage of the company's storage. Alternatively, an interface for selecting a personal delivery request, etc. may be provided, and an interface for paying the corresponding cost with a utility token for internal transaction of tangible and intangible assets may be provided based on the method of handling the successful bid item selected through the interface. Specifically, the successful bid item processing server 350 converts into a utility token for internal transaction of tangible and intangible assets through the mutual exchange module 204 as the cost according to the successful bid item processing method is deposited as a transaction coin, cryptocurrency, and cash. This may be processed by remittance to the company-side encrypted electronic wallet 110 or the user-side encrypted electronic wallet 130 (eg, a personal delivery company-side encrypted electronic wallet).

A method of managing tangible and intangible assets in the tangible and intangible asset trading system 100 as described above will be described with reference to FIGS. 5 and 6.

5 is a flowchart illustrating an operation process of the tangible and intangible asset trading system 100 according to an embodiment of the present invention.

As shown in Figure 5, first, the tangible and intangible asset trading system 100 based on the value of the tangible and intangible asset managed by the tangible and intangible asset management server 320 and a preset unit price of a utility token for internal transaction of tangible and intangible assets. After determining the number of issuance of utility tokens for intra-asset transaction and the number of coins for transaction accordingly, the issuing step of issuing them on the blockchain network is performed (S400). At this time, the exchange transaction coin and the utility token for internal transaction of tangible and intangible assets may be deposited into the company's encrypted electronic wallet 110, and the exchange transaction coin may be listed on the coin exchange 140 and sold to users. In addition, the price of the coin for exchange transaction may fluctuate according to the transaction of the coin exchange 140, and the unit price of the utility token for internal transaction of tangible and intangible assets linked with the value of the coin for exchange transaction may also be changed.

Then, when the tangible and intangible assets valued by an accredited appraisal agency or private institution are purchased, the tangible and intangible asset trading system 100 purchases based on the value of the purchased tangible and intangible asset and the unit price of the utility token for internal transaction of tangible and intangible assets. After determining the number of issuance of utility tokens for internal transaction of tangible and intangible assets for the tangible and intangible assets and the number of coins for transaction accordingly, it is issued on the blockchain network (S402).

In addition, the tangible and intangible asset trading system 100 stores information on tangible and intangible assets according to the purchase of tangible and intangible assets in the tangible and intangible asset database 360 through the tangible and intangible asset management server 320 (S404).

Thereafter, when any one of the tangible and intangible assets managed by the tangible and intangible asset trading system 100 is auctioned off to an arbitrary user, the tangible and intangible asset trading system 100 is a tangible and intangible asset internal transaction issued when the tangible and intangible asset is initially purchased. In addition to incineration of utility tokens and coins for exchange transactions generated accordingly, some of the utility tokens for internal transaction of tangible and intangible assets corresponding to the difference between the successful bid price and the initial purchase price are used to purchase coins for exchange transactions and then incinerate them. Do (S406).

The auction process for tangible and intangible assets as described above will be described with reference to FIG. 6.

6 is a flowchart illustrating a process of providing an auction service in the tangible and intangible asset trading system 100 according to an embodiment of the present invention.

As shown in FIG. 6, first, the tangible and intangible asset trading system 100 generates an auction list including at least one or more of tangible and intangible assets managed by the tangible and intangible asset management server 320 and then provides it to the user-side node 120 Or posted on a web page (S500). In this case, the auction list may include an auction start price determined by the company, owner information, emotion-related information, transaction details, and the like.

Thereafter, when the user selects a specific tangible and intangible asset from the auction list displayed on the user-side node 120 (S502), the auction service providing server 330 of the tangible and intangible asset trading system 100 performs verification on the specific tangible and intangible asset (S510), if a specific tangible and intangible asset is not selected, the user asks whether to participate in the auction with the tangible or intangible asset directly owned (S504), and performs a personal asset auction product registration system (S506). Specifically, the auction service providing server 330 may verify the reliability of a specific tangible and intangible asset by verifying the reliability of a utility token for internal transaction of tangible and intangible assets issued when purchasing a specific tangible and intangible asset on a blockchain network.

Then, whether the user is a posted company auction item (S510) or an individual registered item (S506), asks whether to participate in the joint auction (S512), and if the user participates in the joint auction (S512), performs the joint auction system (S514) Then, the final registered joint auction participant (S516) is determined, and then a bid distribution and deposit message is transmitted (S518). When the deposit of the bid fee is completed (S520) according to the transmission of the message, a request for participation in an auction using a transaction coin or other cryptocurrency (S522) is received.

Thereafter, if the user wants to participate in an auction for a specific tangible and intangible asset, after executing the user-side encrypted electronic wallet 130 on the user-side node 120, enter the transaction coin or other cryptocurrency held by the user to participate in the auction. As the transaction coin or other cryptocurrency entered by transmitting the request to the auction service providing server 330 is set as the bid price, the auction service providing server 330 requests to participate in an auction for a specific tangible and intangible asset from the user-side node 120 Receive (S522). At this time, the user transfers a predetermined bid (entered transaction coin or other cryptocurrency) using the user-side encrypted electronic wallet 130 to the address of the company-side encrypted electronic wallet 110 of the tangible and intangible asset transaction system 100 To participate in the auction. At this time, when a bid remittance transaction occurs due to participation in an auction, not only the transaction specification corresponding to the bidding remittance transaction can be recorded on the blockchain network, but also the transaction coin or cryptocurrency held in the user's encrypted electronic wallet 130 It is deducted by the bid amount.

Accordingly, the auction service providing server 330 converts the transaction coin into a utility token for internal transaction of tangible and intangible assets through the mutual exchange module 204 of the company's encrypted electronic wallet 110, or converts the cryptocurrency into a coin exchange 140 ), and exchange the exchanged transaction coin into a utility token for internal transaction of tangible and intangible assets.After generating the user's bid information with the converted utility token for internal transaction of tangible and intangible assets, the user's node 120 The bidding completion message is transmitted to (S524).

Thereafter, when there is a change in the bid amount by the user, that is, after executing the user-side encrypted electronic wallet 130 on the user-side node 120, the auction service is provided by inputting the transaction coin or other cryptocurrency held by the user. It is transmitted to the server 330 to request a bid price change (S526). At this time, the user uses the user-side encrypted electronic wallet 130 to transfer a predetermined additional bid (entered transaction coin or other cryptocurrency) to the address of the company-side encrypted electronic wallet 110 of the tangible and intangible asset transaction system 100. Request a change in bid price by remittance. At this time, when a transaction occurs according to a change in the bid price, not only the transaction specification corresponding to the change in the bid price can be recorded on the blockchain network, but also the transaction coin or cryptocurrency held in the user-side encryption electronic wallet 130 for the amount entered by the user. Is deducted.

Accordingly, the auction service providing server 330 converts the transaction coin input by the user through the mutual exchange module 204 of the company's encrypted electronic wallet 110 into a utility token for internal transaction of tangible and intangible assets, or the user inputs it. After converting a cryptocurrency to a transaction coin through the coin exchange 140, the exchanged transaction coin is converted into a utility token for internal transaction of tangible and intangible assets, and the user participates in the auction as a utility token for internal transaction of tangible and intangible assets that has been converted. After changing the Bid price change completion message to the user-side node 120 is transmitted (S528).

By repeatedly performing the above-described steps, a plurality of users can participate in an auction using their own transaction coin or cryptocurrency.

Thereafter, when the auction ends, that is, the successful bidder is determined (S530), the auction service providing server 330 is a transaction coin or cryptocurrency corresponding to the bidding amount that the other users excluding the successful bidder, that is, utility token for internal transaction of tangible and intangible assets The money is remitted using the address of the rest of the user's encrypted electronic wallet 130 (S532).

Then, when the ownership of a specific tangible and intangible asset is changed to a successful bidder (S534), the tangible and intangible asset trading system 100 selects a specific tangible and intangible asset among utility tokens for internal transaction of tangible and intangible assets remitted at a successful bid price through the asset sale server 340. The utility token for internal transaction of tangible and intangible assets issued at the time of purchase is burned (S536), and some of the utility tokens for internal transaction of tangible and intangible assets that have been burned are converted into coins for transaction through the mutual exchange module 204 and then exchanged. The dragon coin is burned (S538). Such incineration can be executed by generating a transaction that deducts a portion of utility tokens for internal transaction of tangible and intangible assets that have been remitted to the company's encryption electronic wallet 110 at a successful bid price, and a portion of the utility tokens for internal transaction of tangible and intangible assets remaining after incineration is used. It can be executed by generating a transaction that deducts the received transaction coin from the company-side encrypted electronic wallet 110.
