Figure 2 is a block diagram showing the configuration of an NFT-based O2E art platform according to an embodiment of the present invention.

The NFT-based O2E art platform 10 shown in Figure 2 represents a system that can safely trade digitally created digital art, such as graphic images, animations, etc., in various ways using non-fungible tokens generated on the blockchain. .

Referring to Figure 2, the NFT-based O2E art platform 10 includes a digital art management server 100, a file system 110, a mainnet 200, a creator terminal 300, and a plurality of buyer terminals. Includes 400.

The creator terminal 300 represents a terminal used by a creator who wants to create and sell digital art, and the plurality of buyer terminals 400 represent a terminal used by a plurality of buyers who want to purchase the digital art created by the creator. Indicates the terminals used by.

The NFT-based O2E art platform 10 of FIG. 2 is shown as including one creator terminal 300 for convenience of explanation, but the present invention is not limited thereto, and the NFT-based O2E art platform 10 includes multiple creators. It may also include terminals 300.

Each of the creator terminal 300 and the plurality of purchaser terminals 400 is not limited to a specific type of terminal, but is any type of electronic communication capable of transmitting and receiving data through wired or wireless communication, such as a smartphone, laptop, personal computer, etc. It could be a device.

Meanwhile, the digital art management server 100 is operated by an operator who mediates the transaction of digital art between the creator and the buyer.

The digital art management server 100 may be connected to the mainnet 200 and operate as a node of the mainnet 200.

Accordingly, the digital art management server 100 can store data in the blockchain 210 shared between a plurality of nodes of the mainnet 200 or read data stored in the blockchain 210.

In one embodiment, mainnet 200 may correspond to the Ethereum network.

The digital art management server 100 creates a smart contract (SC) 220 that can issue a non-fungible token with a unique token ID for each digital art and distributes it in advance to the blockchain 210 of the mainnet 200. (deploy) can be done.

As will be described later with reference to FIGS. 2 and 3, when the creator creates the digital art, he or she may sell the digital art to the plurality of buyers through the digital art management server 100.

At this time, the creator can divide and sell the ownership of the digital art, and the creator can directly determine the number of divisions of the ownership of the digital art.

Figure 3 is a flowchart showing a digital art trading method according to an embodiment of the present invention.

The digital art trading method shown in FIG. 3 can be performed through the NFT-based O2E art platform 10 of FIG. 2.

Hereinafter, with reference to FIGS. 2 and 3, the configuration and operation of the NFT-based O2E art platform 10 and the digital art trading method performed by the NFT-based O2E art platform 10 will be described in detail.

The creator who creates the digital art and wants to sell the digital art through the digital art management server 100 divides the original file (O_F) of the digital art and ownership of the digital art through the creator terminal 300. A registration request (R_REQ) including the division number (D_N) may be transmitted to the digital art management server 100.

When the digital art management server 100 receives a registration request (R_REQ) including the original file (O_F) of the digital art and the number of divisions (D_N) for dividing ownership of the digital art from the creator terminal 300 ( Step S210), using a smart contract 220 distributed on the blockchain 210, a non-fungible token of the number of divisions (D_N) having a unique token ID corresponding to the digital art and having the creator's address as the owner address can be created on the blockchain 210 (step S220).

Therefore, the original owner of each of the non-fungible tokens of the division number (D_N) created on the blockchain 210 by the digital art management server 100 in response to the registration request (R_REQ) received from the creator terminal 300 may be set as the creator.

In one embodiment, the smart contract 220 distributed to the blockchain 210 by the digital art management server 100 may be a smart contract written according to the ERC-1155 token standard.

Meanwhile, when the digital art management server 100 generates the non-fungible tokens of the division number (D_N) in response to a registration request (R_REQ), the original file (O_F) of the digital art included in the registration request (R_REQ) After storing in the file system 110 that exists outside of the blockchain 210 and generating metadata (M_D) containing information about the digital art, the metadata (M_D) is stored in the file system 110. It can be saved in .

In one embodiment, file system 110 may be an InterPlanetary File System (IPFS).

In one embodiment, the registration request (R_REQ) received from the creator terminal 300 includes the name of the digital art, in addition to the original file (O_F) of the digital art and the number of divisions (D_N) dividing ownership of the digital art, It may further include a description of the digital art and the creator's electronic signature.

In this case, when the digital art management server 100 generates the non-fungible tokens of the division number (D_N) in response to the registration request (R_REQ), the original file (O_F) of the digital art included in the registration request (R_REQ) ) is stored in the file system 110, and a hash value for the original file (O_F) is calculated, followed by the name of the digital art, a description of the digital art, the creator's address, the creator's electronic signature, Metadata (M_D) including a hash value and a path to the original file (O_F) stored in the file system 110 may be generated and stored in the file system 110.

Thereafter, the digital art management server 100 associates the path to the metadata (M_D) stored in the file system 110 with the token IDs of the non-fungible tokens for the digital art and stores them in the blockchain 210. You can.

Additionally, the digital art management server 100 may additionally store various information about the digital art included in the original file (O_F) and metadata (M_D) of the digital art in an internal database.

As such, the metadata (M_D) for the digital art includes the address of the creator, so that, as described below, the creator sells all the non-fungible tokens for the digital art to replace the non-fungible tokens owned by the creator. Even when the number of non-fungible tokens becomes 0, information that the person who created the digital art corresponding to the non-fungible token is the creator may be continuously stored in metadata (M_D) linked to the non-fungible token.

In general, the size of the original file (O_F) of the digital art is relatively large compared to the size of data that can be stored in one block of the blockchain 210, so the original file (O_F) of the digital art and the digital art When storing metadata (M_D) in the blockchain 210, there is a disadvantage that it requires a lot of time and a lot of cost (gas) for storage.

On the other hand, as described above, the digital art management server 100 included in the NFT-based O2E art platform 10 according to the present invention contains the original file (O_F) of the digital art and metadata (M_D) for the digital art. is stored in the file system 110 that exists outside of the blockchain 210, and the path to the metadata (M_D) stored in the file system 110 and the token ID of the non-fungible tokens for the digital art They are associated with each other and stored in the blockchain 210.

In this way, the original file (O_F) and metadata (M_D) are stored in the file system 110 that exists outside the blockchain 210, so the digital art management server 100 included in the NFT-based O2E art platform 10 ) can reduce the time and cost required to store the original file (O_F) and metadata (M_D), and provide quick access to the original file (O_F) and metadata (M_D), while also providing access to the file system 110. The path to the stored metadata (M_D) and the token IDs of the non-fungible tokens for the digital art are stored in the blockchain 210 in association with each other, so that the information for the digital art created in the blockchain 210 is stored in the blockchain 210. The connection between non-fungible tokens and metadata (M_D) stored in the file system 110 can be clearly guaranteed.

Depending on the embodiment, the non-fungible tokens for the digital art and the original file (O_F) of the digital art are created in the blockchain 210 by changing the contents of the metadata (M_D) stored in the file system 110. In order to prevent the connection between them from being disconnected, the digital art management server 100 may additionally store at least one of the information included in the metadata (M_D) in the blockchain 210.

For example, the digital art management server 100 further stores the path to the original file (O_F) stored in the file system 110 included in the metadata (M_D) in the blockchain 210, thereby ) may further strengthen the connection between the non-fungible tokens for the digital art created in ) and the original file (O_F) stored in the file system 110.

Referring again to FIGS. 2 and 3, after the digital art management server 100 generates the non-fungible tokens of the division number (D_N) for the digital art in response to a registration request (R_REQ), the creator Using impossible tokens, ownership of the digital art can be divided and sold.

In one embodiment, the creator may divide and sell ownership of the digital art through an auction.

Specifically, the creator terminal 300 is an auction that includes a sale number (A_N) corresponding to the number of non-fungible tokens to be sold through auction among the non-fungible tokens of the division number (D_N) for the digital art. A request (A_REQ) may be transmitted to the digital art management server 100.

When the digital art management server 100 receives an auction request (A_REQ) including the sale number (A_N) of the non-fungible token for the digital art from the creator terminal 300 (step S230), the auction request (A_REQ ), an auction may be registered for the non-fungible tokens of the sale number (A_N) for the digital art (step S240).

In one embodiment, when the digital art management server 100 receives an auction request (A_REQ) from the creator terminal 300, the non-fungible tokens of the division number (D_N) generated for the digital art are The number of non-fungible tokens that have the creator's address as the owner address can be inquired.

If the number of inquiries is less than the number sold (A_N), the creator has requested to sell more non-fungible tokens through auction than the number of non-fungible tokens currently owned by the digital art management server (100) ) may transmit a non-auction message to the creator terminal 300 and not initiate an auction for the non-fungible tokens of the sale number (A_N).

On the other hand, if the viewed number is greater than or equal to the sale number (A_N), the digital art management server 100 will initiate an online auction for the non-fungible tokens of the sale number (A_N) for the digital art. You can.

For example, the digital art management server 100 posts a bidding screen on which a plurality of buyer terminals 400 can bid for the non-fungible tokens of the sale number (A_N) for the digital art, thereby providing the online The auction can begin.

When the online auction is started, the digital art management server 100 receives a bid amount (A_P) for the sale number (A_N) of the non-fungible tokens from a plurality of buyer terminals 400, and receives a bid amount (A_P) from a plurality of buyer terminals 400. Among the terminals 400, the buyer corresponding to the buyer terminal that transmitted the highest bid amount (A_P) may be determined as the successful bidder (step S250).

In one embodiment, the auction request (A_REQ) may further include a minimum bid amount for the sale number (A_N) of the non-fungible tokens.

In this case, the digital art management server 100 may determine only a bid amount (A_P) greater than or equal to the minimum bid amount as a valid bid amount among the bid amounts (A_P) received from a plurality of buyer terminals 400. , if there is no valid bid amount among the bid amounts (A_P) received from the plurality of buyer terminals 400, the online auction may be terminated.

Meanwhile, when the successful bidder is determined, the digital art management server 100 transmits the bid amount (A_P) transmitted by the buyer terminal 400 of the successful bidder from the successful bidder's electronic wallet to the creator's electronic wallet, and blocks The non-fungible tokens of the number (A_N) sold for the digital art can be transferred from the creator's address to the successful bidder's address using the smart contract 220 distributed on the chain 210 (step S260).

Additionally, the digital art management server 100 may store a history of changes in ownership of the non-fungible tokens of the sale number (A_N) from the creator's address to the successful bidder's address in the blockchain 210 (step S270).

In one embodiment, the digital art management server 100 transmits the sale number (A_N) of the non-fungible tokens for the digital art from the creator's address to the successful bidder's address (step S260) and the sale number. An operation (step S270) of storing the history of changes in the ownership of the non-fungible tokens of (A_N) from the creator's address to the successful bidder's address in the blockchain 210 can be performed at the same time.

For example, the digital art management server 100 may use the TransferSingle event or the TransferBatch event implemented in the smart contract 220 according to the ERC-1155 token standard to collect the sale number (A_N) of the non-fungible token for the digital art. An operation of transferring tokens from the creator's address to the successful bidder's address and an operation of storing the history of changes in ownership of the non-fungible tokens of the sale number (A_N) from the creator's address to the successful bidder's address in the blockchain 210. can be performed simultaneously.

In one embodiment, as shown in FIG. 2, the NFT-based O2E art platform 10 may further include an exchange server 120.

In one embodiment, the exchange server 120 may be operated by the operator who operates the digital art management server 100.

Hereinafter, a method of renting the digital art using the non-fungible token will be described in detail.
