This paper extends the dialogue of "The Moral Character of Cryptographic Work" (Rogaway, 2015) and "Crypto for the People" (Kamara, 2020) by examining the relationship between cryptography and collective power. In particular, it considers cryptography in the context of grassroots organizing—a process by which marginalized people build collective power toward effecting systemic change—and illustrates the ways in which cryptography has both helped and hindered organizing efforts. Based on the synthesis of dozens of qualitative studies, scholarly critiques, and historical artifacts, this work introduces a paradigm shift for cryptographic protocol design—general principles and recommendations for building cryptography to address the lived needs and experiences of marginalized people. Finally, it calls for abolition cryptography: cryptographic theories and practices which dismantle harmful systems and replace them with systems that sustain human lives and livelihoods.
