First-generation NFTs are non-fungible tokens that represent unique digital assets and can be attached to a specific wallet. They were introduced early in 2017 and are often used to represent digital art, collectibles, and other unique digital assets. Unlike fungible tokens, NFTs cannot be exchanged for an equal value, as each NFT is unique and has its own value based on the rarity, authenticity, and demand of the associated digital asset. First-generation NFTs are considered static because they do not have any built-in functionality or interactivity, but new developments in blockchain technology are allowing for the creation of dynamic NFTs. Despite the controversy surrounding the environmental impact of blockchain technology, the use of NFTs is expected to continue to grow in popularity and expand beyond the art world.
