The specific concept, the abbreviation of NFT-non-fun token, stands for heterogeneous token and is a unique digital asset (art, music or game asset). You can think of it as an encrypted currency token.
Digital collection can be understood as a characteristic of China, which is essentially a regulated NFT. They are digital specific works, artworks and commodities uniquely identified by blockchain technology, such as digital paintings, pictures, music, videos and 3D models. Each digital set maps a unique sequence on a specific blockchain and cannot be tampered with, divided or replaced.
Each digital collection represents a single digital copy of a specific work, artwork and commodity or its limited sales, and records its unbreakable rights in the chain. Therefore, digital collection is essentially different from homogeneous tokens such as virtual currency, which is supported by the actual value of specific works, artworks and commodities, and does not have any monetary attributes such as payment function.
