Description

NFT smart contract system

The present invention relates to an NFT smart contract system, and more specifically, an NFT smart implemented so that the fixed value of NFT works can be guaranteed through PAY-TOKEN, unlike works purchased with other key digital assets whose value changes. It is about the contract system.

NFT (Non-Fungible Token) means a non-fungible token, and it is a technology that can prove the owner by giving a unique code to a digital asset and recording it on the blockchain. With this technology, anyone can easily identify the owner of the corresponding digital asset and can easily trade it through private or NFT exchanges.

In particular, it is a technology that greatly helps to revitalize the market by giving value to digital art by using NFT in the artistic field.

Basically, all transactions (purchase, sale, transfer of ownership) in the block chain require a fee gas fee (cryptocurrency). However, buyers under the age of 18, who are the main consumers of idol NFT purchases, have a disadvantage in that it is difficult to purchase NFTs because it is not easy to even sign up for an exchange.

On the other hand, the above-mentioned background art is technical information that the inventor possessed for the derivation of the present invention or acquired in the process of derivation of the present invention, and it cannot be said that it is necessarily a known technique disclosed to the general public before the filing of the present invention. .

Referring to FIG. 1 , an NFT smart contract system 10 according to an embodiment of the present invention includes a purchaser terminal 100 and a smart contract server 200 .

The purchaser terminal 100 is connected to the smart contract server 200 through the network N, a dedicated application for providing NFT smart contract service is installed, and access to a web page for providing a dedicated application or NFT smart contract service It allows the buyer to search for and purchase the NFT-ized online content (P) that he/she wants to purchase.

The smart contract server 200 makes the online content (P) requested for sale from the creator into NFT, and the NFT-ized online content (P) through a dedicated application for providing NFT smart contract service or a web page for providing NFT smart contract service ) to relay the purchase.

The NFT smart contract system 10 according to an embodiment of the present invention having the configuration as described above may further include a creator terminal 300 .

The creator terminal 300 transmits the online content created by the creator to the smart contract server 200 through the network N, and the NFT-ized online content P sold through the smart contract server 200 Receive the remittance amount excluding the sales commission for the payment for Korea.

Here, the purchaser terminal 100 may be composed of one or more, and is widely used by the general public such as a desktop computer (PC), as well as a notebook (Notebook), a smart phone (Smart Phone), a tablet computer (Tablet PC), etc. It is a broad concept meaning various types of information communication devices and multimedia devices supporting wired and wireless networks, such as mobile communication terminals.

In addition, the creator terminal 300 may be composed of one or more, and is widely used by the general public, such as a desktop computer (PC), as well as a notebook (Notebook), a smart phone (Smart Phone), a tablet computer (Tablet PC), etc. It is a broad concept meaning various types of information communication devices and multimedia devices supporting wired and wireless networks, such as mobile communication terminals.

In addition, the network N may include, for example, wireless communication, wired communication, optical ultrasound, or a combination thereof. Body Area Network (BAN), satellite communication, cellular communication, Bluetooth, Near Field Communication (NFC), Infrared Data Association standard (IrDA), Wireless Fidelity (WiFi), and Worldwide Interoperability for Microwave access (WiMAX) are included in the communication path. Ethernet, Digital Subscriber Line (DSL), Fiber to the Home (FTTH), and Plain Old Telephone Service (POTS) are examples of wired communication that can be included in a communication network. In addition, the communication network may traverse multiple network topologies and distances. For example, the communication network may include a direct connection, a personal area network (PAN), a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), or any combination thereof. In addition, it may be achieved through a low power wide area network (Low Power Wide Area Network) including LoRaWAN, NB-Fi, and RPMA. However, as for the network N, the description of the communication network is not limited to the above-described communication network, and any latest data communication network may be applied.

In one embodiment, the smart contract server 200 is a dedicated application for providing NFT smart contract service for the amount that the purchaser pays through at least one type of currency among virtual currency, cash, and card through the purchaser terminal 100 , or Through the web page for providing NFT smart contract service, it can be converted into pay tokens for the purchase of NFT-ized online content (P) and paid.

Basically, all transactions (e.g., purchase, sale, transfer of ownership, etc.) in the block chain require a fee gas fee (cryptocurrency), but buyers under the age of 18 who are the main consumers of idol NFT purchases It has a problem that it is difficult to purchase NFTs because even joining an exchange is not easy.

Accordingly, the smart contract server 200 according to the present invention implements that the purchaser pays through at least one type of currency among virtual currency, cash and card through the purchaser terminal 100, so that it is difficult to access the existing virtual currency. This will allow consumers to become buyers.

In one embodiment, the smart contract server 200 may specify ownership with a nickname or ID so as not to remain in the block chain record.

In one embodiment, the smart contract server 200, in the case of issuance of a pay token for the purchase of NFT-ized online content (P) through a dedicated application for providing NFT smart contract service or a web page for providing NFT smart contract service It can block the inflow of Pay tokens through external inflows and allow them to flow only through its own phone system through an allowed dedicated application or web page.

In one embodiment, the smart contract server 200 receives a pay token for purchasing NFT online content (P) through a dedicated application for providing NFT smart contract service or a web page for providing NFT smart contract service in KRW or USD It can be issued as a fixed-value token with fixed values and fiat currencies of each country.

In one embodiment, the smart contract server 200 may sell the NFT-ized online content (P) without a gas fee.

That is, when withdrawing NFT to the outside of the market, it is necessary to record a transaction for the transfer of ownership in the block chain in order to record data on-chain. Because it is a model that pays for gas, users can avoid paying gas fees at all.

In an embodiment, the smart contract server 200 may relay the purchase of NFT-ized online content in a hybrid method that integrates an off-chain method (DB) and an on-chain method (blockchain).

In the NFT smart contract system 10 according to an embodiment of the present invention having the above-described configuration, the NFT market is not a decentralized method, but a centralized exchange method such as a virtual currency exchange. Using the chain method, even people who do not know anything about cryptocurrency can use it, and since it is a model in which the operator, not the user, pays the gas fee, the user can save the purchase cost by not paying the gas fee at all.
