Synopsis

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.

From the Back Cover

Security underpins digital life. Yet in decentralised systems, it has no central operator.

This book enters the uneasy world of blockchain security: war rooms assembled across time zones, anonymous white hat ('for good') hackers racing to patch vulnerabilities before funds vanish, protocol developers debating whether intervention betrays the very principles their systems were built to protect. Born from public key cryptography and libertarian aspirations, blockchain infrastructures promise trustless coordination. In practice, they endure through paranoia, vigilance, improvisation and cooperation.

Drawing on immersive digital ethnography, the book traces how security is organised where authority is fluid and legitimacy contested. Persistent insecurity becomes not an exception but a governing condition, shaping alliances between hackers, exchanges, investigators and nation-state authorities. From volunteer responders tracing stolen funds to North Korean state-sponsored exploits, securing blockchain systems reveals an ecosystem where code, grassroots security coalitions and geopolitics converge.

What emerges is a model of security coordination forged in infrastructures designed to resist centralised control. At a time when cyber insecurity is structural, the book advances an account of how decentralised systems are reshaping the architecture of security governance.
