This main feature makes up the nascent and emerging phenomenon that has revolutionized the way digital assets are and will be handled in the future. Its success and importance has resonated particularly in the first and second quarter of 2022, and however, the full application and reach of NFTs through its technology in human life are still yet to be discovered. The main objective of this chapter is to inform the audience of developments in the research field, discuss the importance and significance of the issues investigated to analyze the relevance and suitability of the topic in order to inform the audience about its operations, and generate, through the NFTs, economical value and further knowledge for future applications. This is the reason why a systematic review of the literature on the subject of “non-fungible tokens” is carried out based on publications of Scopus indexed journals, with a collection of information from 2017 to 2022.enNon-fungible tokenBlockchainLiterature reviewResource Types::text::book::book part
