Description
System for NFT blockchain contract based on percentage unit transaction and method therefor The present invention relates to an apparatus for a percentage-based transaction NFT blockchain contract and a method for the same. A smart contract refers to the execution of various types of contracts, such as financial transactions, real estate agreements, and notarization, based on blockchain technology. FIG. 1 is a diagram illustrating the configuration of a system for a percentage-unit transaction-based NFT blockchain contract according to an embodiment of the present invention. FIG. 2 is a flowchart illustrating a method for creating a smart contract for selling content according to an embodiment of the present invention. FIG. 3 is a flowchart illustrating a method for creating a smart contract for selling content revenue shares based on percentage unit transactions according to an embodiment of the present invention. FIG. 4 is a flowchart illustrating a method for purchasing content revenue shares according to an embodiment of the present invention. FIG. 5 is a diagram illustrating an apparatus for a percentage-unit transaction-based NFT blockchain contract according to an embodiment of the present invention. Prior to the detailed description of the present invention, the terms and words used in the specification and claims described below should not be interpreted as being limited to their ordinary or dictionary meanings. Instead, they should be interpreted in a sense and concept consistent with the technical spirit of the present invention, based on the principle that the inventor may appropriately define the concept of the terms to best describe his invention. Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all aspects of the technical spirit of the present invention. It should be understood that various equivalents and modifications capable of replacing them may exist at the time of filing this application. Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that identical components in the accompanying drawings are indicated by the same reference numerals whenever possible. Furthermore, detailed descriptions of known functions and configurations that could obscure the essence of the invention will be omitted. For the same reason, some components in the accompanying drawings may be exaggerated, omitted, or schematically depicted, and the size of each component does not entirely reflect its actual size. First, a system for a percentage-based transaction-based NFT blockchain contract according to an embodiment of the present invention will be described. FIG. 1 is a diagram illustrating the configuration of a system for a percentage-based transaction-based NFT blockchain contract according to an embodiment of the present invention. Referring to FIG. 1, a system for an NFT blockchain contract according to an embodiment of the present invention includes a seller device (10), a buyer device (20), a front-end device (100), a back-end device (200), a contract network (300), and an IPFS (400, InterPlanetary File System). The seller device (10) is a device used by a user who wishes to sell content or an NFT representing a share of content revenue according to an embodiment of the present invention, that is, the original creator of the content or a seller who holds a share of the content revenue. Here, the content can be any digital content, such as music, video, YouTube content, games, digital art, etc. The seller device (10) is a device capable of performing computing operations by connecting to a network. For example, the seller device (10) can be exemplified by a computer, a smartphone, etc. The buyer device (20) is a device used by a user, i.e., a buyer, who wishes to purchase an NFT, which is a share of the content revenue. The buyer device (20) is a device capable of performing computing operations by connecting to a network. For example, the seller device (10) can be exemplified by a computer, a smartphone, etc. The front-end device (100) and the back-end device (200) are service servers for providing a service to issue and sell NFTs according to an embodiment of the present invention. The front-end device (100) and the back-end device (200) may be implemented as a single device or as separate devices. The contract network (300) may be a blockchain network that executes a smart contract for issuing and selling NFTs according to an embodiment of the present invention. Accordingly, the contract network (300) includes a plurality of nodes (N) that constitute the blockchain network. A node (N) is a device that can perform computing operations by connecting to the network. For example, a node (N) may be an example of a computer, a smartphone, etc. The operation of the contra
