I always admire the artistic aspect of banknotes; however, I think about the future that banknotes are antiquated. I started a project to give a souvenir to the future, that only emphasizes the art behind the banknotes, rather than Economic and political values. So, for the international community formed based on blockchain technology, I designed banknotes for this new environment, that is not backed by any governments. NFT banknote is the first part of this project.
