Decentralised digital security
Code, crisis, community
by Kelsie Nabben
Decentralised digital security offers a compelling exploration of how digital security is practiced, organised and contested within blockchain communities. Drawing on immersive digital ethnography, the book examines how decentralised technologies - rooted in cryptography and designed to operate without central control - depend on not just technical systems but social infrastructures for incentive alignment and coordination. Through first-hand case studies, it reveals the white hat hackers, social infrastructures and ecosystem-wide efforts that make blockchain security possible. At a time of growing concern over digital security, the book provides a timely investigation into how security is enacted across decentralised networks, and what these practices reveal about digital security more broadly.
