This paper is really about solving a fundamental problem in decentralized identity, which is to combine the characteristics of self-sovereignty, privacy and Sbil-resistance, which seems to exclude each other.
I previously proposed formalizing this problem as Decentralized Identity Trilemma (http://maciek.blog/dit).
