In 2021, NFTs gained notoriety in the universe of visual arts, after a work of art using this technology was auctioned at Christie s for USD 69.3 million, arousing the curiosity of art lovers and critics, artists, collectors and institutions. A great excitement took over the circuit, raising questions, including whether a new historical moment was beginning, in which traditional art would lose ground to crypto art as a reflection of an increasingly digital world, and whether the emergence of this novelty pointed to a new aesthetic revolution. The purpose of this research is to present and problematize the novelty of NFTs in the art universe, in view of their complexity, challenges and opportunities, with the aim of mapping the debate around the theme and stimulating a critical reflection. The dissertation is divided into three parts. The first is dedicated to explaining what NFTs are, the context in which they emerged and their impact on the traditional art market. The second brings a reflection on the prospects for market transformation, considering the challenges presented by digital art and ideas associated with concepts such as originality and authenticity. For this, I turn to the legacy of three artists who revolutionized the art system in the last century: Marcel Duchamp, Andy Warhol and Damien Hirst. And the third part, the conclusion, presents an analysis of the impact of the arrival of NFTs in the art universe, weighing the initial expectations and considering the directions in which this new technology points in its current stage of exploration.
