NFTs beyond the visible ::poised between en bloc rejection and new chains of value

NFTs (non-fungible tokens) appeared in 2017. They are tamper-proof decentralized digital certificates which have gained fame because of their appropriation by the art world. NFTs have attracted a great deal of controversy, and are frequently accused of being speculative, useless and polluting. We propose to examine these polemics, founded for the most part, in order to show that other approaches are possible. In fact, artistic applications are merely one link in the chain, and NFTs cannot be reduced to their mere visible aspect, they require a wider examination of their value systems, distribution chains, and methods of governance
