In addition, NFT transactions that prove the ownership of actual works of art may cause duplicate ownership transactions. Some companies offer various interpretations of NFTs such as public offering type, stock type, and rental type, and sell real ownership NFTs. Since it owns, there is a possibility that the real thing may be sold again to a third party due to the seller's moral hazard. For example, if a real art object that has already sold its ownership NFT is sold to a third party, the NFT on the blockchain must be lost or liquidated.

In addition, the existing art joint purchase method is a structure in which the seller secures liquidity while maintaining ownership of the work. In other words, the transaction history, which is one of the factors that increase the price of the work, does not occur. Not everyone owns it, but nobody owns it. Therefore, art works that sell well in the online and offline auction market are not easily expressed in the online group purchase market.

At the time when the sale of the token for ownership of the art is completed, the online auction sales unit 230, the profit distribution providing unit 240, and the settlement processing unit 250, etc. can include

The token issuing unit 210 calculates the art price for the art upon receiving the art registration request from the art owner's side terminal 100, and uses the art for ownership based on the calculated art price, the predetermined minimum participation amount, and the expected rate of return. After determining the amount of token issuance (refer to Equation 1 below), token issuance information for art ownership may be generated based on this determination.

[Equation 1]

Amount of issued tokens for art ownership = {art product price + (art product price * expected rate of return)}/minimum participation amount

In addition, the token issuing unit 210 may issue a token for ownership of a work of art based on issuance information of a token for ownership of a work of art. That is, the token issuing unit 210 may set the receiving address of the token for ownership of the art object as the address of the electronic wallet of the owner of the art object and transmit and issue the issuance information of the token for ownership of the art object. Token issuance information for art ownership can be recorded on the blockchain created by

The token sale unit 220 is for selling the token for ownership of the artwork, and may sell the token for ownership of the artwork through a primary sales process for selling to the achiever side and a secondary sales process for selling to the general participant.

First, the token sales unit 220 may transmit a message informing of the art token sale to the plurality of achiever-side terminals 110 for the first sale process, or may provide art token sale information to the achiever side through a web posting.

Accordingly, the token selling unit 220 receives token purchase requests including the token purchase amount from the plurality of achiever-side terminals 110, and in response to this, after performing payment through a predetermined payment process, the art work corresponding to the token purchase amount In addition to sending the ownership token to the address of the Achiever-side electronic wallet that requested the purchase, transfer transaction data can be recorded on the blockchain. Here, the transfer transaction data may include that the owner of the token for ownership of the art object corresponding to the purchase amount of the token has been transferred from the art object owner side to the achiever side that has requested the purchase.

Meanwhile, the token selling unit 220 may end the primary sales process and perform the secondary sales process as more than half of the issued amount, for example, 51% or more of art ownership tokens are sold through the secondary sale process.

For the secondary sale process, the token sales unit 220 may transmit a message informing the sale of the art product token to the terminals 120 of the plurality of participants, or may provide art product token sale information to the plurality of participants through a web posting.

Accordingly, the token selling unit 220 receives a token purchase request including the token purchase amount from the plurality of participant terminals 120, and in response to this, after performing payment through a predetermined payment process, the art work corresponding to the token purchase amount In addition to sending the token for ownership to the address of the electronic wallet of the participant who requested the purchase, transfer transaction data can be recorded on the blockchain. Here, the transfer transaction data may include that the owner of the token for ownership of the art object corresponding to the token purchase amount has been transferred from the art object owner side to the participant who requested the purchase.

On the other hand, the secondary sales process is for the rest except for the art product ownership tokens sold through the primary sales process, and may mean, for example, that 49% of the art product ownership tokens are sold.

When the secondary sale process is completed, for example, 49% of the art ownership tokens are sold or a predetermined time has elapsed, the token sale unit 220 sends a message informing of the completion of the token sale to the value of purchasing the art ownership tokens. It can be provided to the terminals 110, 120, and 100 of the server, participant, and owner of the artwork, or posted through the web.

Thereafter, the online auction sales unit 230 calculates the primary art price based on the issued amount of art ownership tokens and the minimum participation amount, and determines the online auction starting price based on the calculated primary art price and the sales volume of art ownership tokens ( After performing Equation 2), an art auction request including an online auction starting price is transmitted to the online auction server 130 to request an art sale through an online auction.

[Equation 2]

Online auction starting price = (issued amount of tokens for art ownership * minimum participation amount) * (1 + incentive rate according to token sale rate)

In Equation 2, the incentive ratio according to the token sale rate may be information set in the art trading server 200 .

As the art work is successfully bid by the online auction server 130, the profit distribution providing unit 240 receives the successful bid price from the online auction server 130, and based on the successful bid price, the art work ownership token for each amount of the art work ownership token held. The return of (see Equation 3) and the rate of return (see Equation 4) can be calculated.

[Equation 3]

Profit of Tokens for Art Ownership =[{Successful Bid Price - (Issuance Amount of Art Ownership Tokens * Minimum Participation Amount)} * (1 - Fee Rate)] * (Amount of Art Ownership Tokens)

[Equation 4]

Yield rate = [{Successful bid price - (Issuance amount of tokens for art ownership * minimum participation amount)} * (1 - commission rate)]*100

The profit dividend providing unit 240 may calculate the profit according to the holding amount of the token for ownership of the art work, and then settle it to a plurality of achievers and participants based on pre-contracted smart contract conditions.

As the settlement is completed, the settlement processing unit 250 deletes the token for ownership of the art object from the block chain using the issuance information of the token for ownership of the art object and the information of the owner of the token for ownership of the art object (that is, the address of the electronic wallet). can be incinerated.

Meanwhile, the artwork trading server 200 according to an embodiment of the present invention may further include a second token issuing unit 260 for issuing a license NFT (LNFT).

As shown in FIG. 3 , the art trading server 200 calculates the price of the art product through an art review process as the art object registration request is received by the art object owner's terminal 100 (S300), and the calculated art object. Based on the price and the predetermined minimum participation amount, a token for art ownership is issued on the blockchain network 10 (S302).

Then, the art work trading server 200 performs a procedure for selling a part of the art work ownership token to the pre-registered achiever side (ie, the first sale procedure) (S304). Specifically, the art work trading server 200 may perform a procedure for selling more than half of the issued amount of art work ownership tokens (hereinafter referred to as 'advance ownership transfer amount') to at least one achiever side.

According to such a selling procedure, the art work transaction server 200 transmits the amount of the art work ownership token requested for purchase using the electronic wallet address of the achiever-side terminal 110 requesting the purchase of the art work ownership token, and then makes a corresponding transaction. By recording data on the blockchain created by the blockchain network 10, ownership of a portion of the token for ownership of the artwork can be transferred.

Thereafter, the art work trading server 200 determines whether the primary sale has been completed, that is, the sale of the amount of transfer of ownership in advance has been completed (S306).

As a result of the judgment in S306, if the sale is completed, the art trading server 200 proceeds to sell the token for ownership of the art work to at least one or more participants other than the achiever side of the issued amount excluding the pre-ownership transfer amount (ie, , Secondary sales procedure) is performed (S308). Specifically, the art trading server 200 provides a transaction interface for selling the tokens for ownership of the art work of the issued amount excluding the amount of pre-ownership transfer to at least one participant's terminal 120, and then the participant who requests purchase through the transaction interface. By transferring the ownership to the participant who requested the purchase using the address of the electronic wallet in the terminal 120 of the side, the token for ownership of the art work of the remaining issued amount can be sold.

Thereafter, the art trading server 200 determines whether the secondary sale is complete, that is, by checking whether the predetermined time has elapsed or whether all the tokens for ownership of the art work of the remaining issued amount have been sold (S310).

As a result of the determination in S310, when the secondary sale is complete, the art trading server 200 calculates the starting price for the online auction, and then requests the online auction server 130 to conduct an online auction for the artwork based on the calculation (S312).

Thereafter, as the successful bid for the artwork is completed by the online auction server 130, the art transaction server 200 receives the successful bid price from the online auction server 130 (S314), and owns the token for ownership of the art based on the successful bid price. Profits are distributed to one participant and the achiever side (S316).

Then, the art work trading server 200 deletes the art work ownership token through a process of incineration (S318). Here, the incineration procedure may be performed using information about the owner of the token for ownership of the art work.
