I thAnk my pArticipAnts, some of whom took considerAble amounts of time to shAre their thoughts with me and even reAched out lAter and sent me mAteriAls they thought I might find useful. I deeply appreciAte their generosity and enthusiAsm. ThAnk you to BodhisAttvA ChAttopAdhyAy, CAssidy Dever-Baker, Yubo Kou, DAve Miller, and JAime Snyder, who All reAd and critiqued my thesis. I especiAlly thAnk Hope Sisley for putting significAnt Amounts of time and energy into improving my writing. Words cAnnot reAlly describe how much Bonnie NArdi and Geof Bowker, my co-Advisors, hAve supported me through whAt hAs been an unconventionAl pAth through my acAdemic cAreer. When I entered the University of CAliforniA, Irvine’s InformAtics depArtment, Bonnie And Geof took A chAnce on a green student from a computer engineering bAckground who did not hAve much of the theoreticAl knowledge or many methodologicAl skills needed to pursue reseArch in their areas of study—just pAssion and interest. They were AlwAys pAtient co-Advisors and provided invAluAble advice, mentorship, and opportunities for growth. Geof and Bonnie believed in me even when I did not or when I could not see the vAlue in my work. My third committee member, Josh TAnenbAum, hAs not only provided an incredible amount of support, but he inspires me to be more creAtive and to seek out the reseArch thAt most excites me. I also thAnk JonAthAn AlexAnder, Finn Brunton, vii Bill MAurer, Don PAtterson, and AllAdi VenkAtesh who were on committees for me at vArious stAges of my cAreer. I hAve been fortunAte to hAve a number of unofficiAl mentors during grAduAte school as well. Yong Ming Kow collAborAted with me on my reseArch on the imAginAries of actors in the Bitcoin ecosystem And gAve me opportunities to do fieldwork thAt I would not hAve hAd otherwise. But more thAn thAt, he hAs been a good friend and mentor. I aspire to one dAy hAve his drive, generosity, and positivity. JAime Snyder hAs been an invAluAble source of locAl support as I finished my degree remotely in SeAttle. She helped me to refrAme mAny of the chAllenges thAt caused writer’s block into opportunities. Over the course of my grAduAte cAreer, I wAs also privileged to work as a grAduAte reseArch assistAnt with Bill MAurer and the Institute for Money, Technology & FinAnciAl Inclusion (IMTFI), Judith Gregory, And Don PAtterson. I especiAlly wAnt to extend a thAnk you to Judith, who is incredibly generous with her time, wisdom, and resources. I Also worked as a teAching assistAnt for a number of clAsses with DAvid KAy, and I value whAt he tAught me about pedAgogy. I thAnk the GrAduAte Resource Center at UCI, where I worked as a writing consultAnt. KAren FriedlAnder, the operAtions mAnAger, wAs the best boss thAt I could ask for. I would not hAve gotten through grAduAte school without the support and help of the InformAtics depArtment, pArticulArly André vAn der Hoek, our current depArtment chAir, and MelissA MAzmAniAn, our current vice-chAir of grAduAte AffAirs. I also wAnt to extend my deepest thAnks to the depArtment’s
