This book compiles some of my work with nfts (non-fungible tokens). Nfts are works of art that, though digital, are unique in themselves just as physical paintings, drawings or sculptures. Nfts are part of the so-called Ethereum blockchain, as a sort of crypto currency that also includes all sorts of digital art (video, audio, documents, pictures, even this book, etc.) susceptible to being minted as an nft. Nfts reflect, for the most part, simplicity, minimalism and, in a way, our embellishment with signals. As such, they usually represent nothing, but are part of an experience. Indeed, in contrast to other nfts on offer, the ones included in the book have meaning and, for the most part, present visual arguments supporting a topic. This will become evident for readers coming from all walks of life.
