3: Core Identities for Future Transaction Systems (pages 53–64)
The chapter explores the evolution and technical foundations of core identity protocols and systems essential for future transaction systems, including anonymous identity schemes and the development of IAM frameworks like Web-SSO and OAuth 2.0. It further examines identity federation models that enable scalable and trusted sharing of user attributes across organizations, highlighting the role of attribute providers and introducing the OPAL paradigm, which advances privacy-preserving data sharing through vetted algorithm execution, strong auditability, and user consent mechanisms.
