I want a short, insightful, 280-character answer to this question: Why is identity management a hard problem in a decentralized system?
Replying to @vgr
Identity is easy, but protection against impersonation and multiple identities hard without central access control. Shared secrets, with identified trustable repos to establish them solve impersonation, recursive vouchsafing, token scarcity and history tracking limit sockpuppets.
