NFTD serves as an innovative marketplace for digital products, operating under a smart NFT framework. Within this advanced shopping environment, each seller and their respective products are assigned a distinct tokenID, ensuring unique identification. Upon the completion of a transaction, the buyer's ownership is instantly verified. A non-fungible token (NFT) represents a digital asset whose unique identity and ownership are recorded on a blockchain, which acts as a secure digital ledger. Unlike traditional currencies, NFTs cannot be exchanged on a one-to-one basis due to their uniqueness. Typically, NFTs are generated by uploading digital files, such as artwork, to an auction platform. Navigating copyright rights for music or logos in the current market can be an intricate and lengthy process; however, NFTs simplify and expedite this procedure significantly. Furthermore, a digital artwork may contain coded data relating to its individual pixels, while tokenized items in video games can hold information that enables the game client to recognize the item owned by the player, including its specific attributes and characteristics. This technological advancement not only enhances ownership verification but also revolutionizes the way digital assets are managed and traded.
