The rise of blockchain technology has sparked interest in decentralized identity management (DIdM). However, DIdM's interdisciplinary nature has led to a fragmented understanding. We propose a “Task Structure-Technological Properties-Fit” framework to clarify the application of DIdM across tasks and contexts. We conducted a comprehensive review of 149 DIdM papers to define task structure (task goals and stakeholder values), task goals (identity value creation and value maintenance), stakeholders (users, service providers, identity issuers, regulators, and infrastructure builders), and DIdM properties (interoperability and self-sovereignty). We explored how these elements could align and then highlight research gaps and present a DIdM research agenda.

区块链驱动的去中心化身份管理：跨学科审查和研究议程


区块链技术的兴起引发了人们对去中心化身份管理（DIdM）的兴趣。然而，DIdM 的跨学科性质导致了人们的理解支离破碎。我们提出了一个“任务结构-技术属性-适合”框架来阐明 DIdM 跨任务和上下文的应用。我们对 149 篇 DIdM 论文进行了全面审查，定义了任务结构（任务目标和利益相关者价值）、任务目标（身份价值创造和价值维护）、利益相关者（用户、服务提供商、身份发行者、监管机构和基础设施建设者）以及DIdM 属性（互操作性和自我主权）。我们探讨了如何协调这些要素，然后突出研究差距并提出 DIdM 研究议程。
