White Papers on Dissent investigates blockchain technology as a tool for radical imagination. It moves away from economic discourses to understand this technology as a social apparatus, which can organise social life circumventing hegemonic economic principles, like the accumulation of capital and the focus on productivity. This PhD aims to explain how the technology can concoct new social imaginaries, where the creativity to adapt its affordances conveys new elsewheres and otherwises: new forms of utopia with a biopolitical production adjusted to the characteristics and desires of the post-digital society. White Papers on Dissent examines blockchains through two complementary angles: the politics within the technology and its aesthetic experimentations. On the one hand, White Papers on Dissent delves into how the different uses of the technology develop of new political imaginaries, forms of subversion, and activism. On the other hand, it explores how artists working with blockchains give rise to new forms of aesthetic resistance as they are exercises that recreate, in the present, a desired unwritten future. These artistic projects turn into speculative performances whereby artists and likeminded agents anticipate a potential society to come. As such, these practices come to deepen the project of Institutional Critique, and expand the medium of socially engaged art to compose new forms of digital dissent.
