I just scanned the paper at a high level, and I think many of the topic areas have merit, but since the analysis primarily focused at Ethereum at Layer 1/2 it’s doesn’t account for the Indy/Aries framework being advanced for SSI. I think there are elements throughout the paper to consider if we contrast it to the TOIP stack, to include consideration of VCs.

I think this was the important insight of the paper here.  And I wonder if it can be solved with verifiable credentials?

"If blockchains are to become a significant public infrastructure, particularly in the space of civic engagement, then Proof of Work's “one-CPU-one-vote” or Proof of Stake's “one-dollar-one-vote” systems will not suffice: in order to enable democratic governance, protocols that signal unique human identities to enable "one-person-one-vote" systems must be created."

Keywords: decentralized identity, Sybil-protection, crypto-governance


Most self-sovereign identity systems consist of strictly objective claims, cryptographically signed by trusted third party attestors. Lacking protocols in place to account for subjectivity, these systems do not form new sources of legitimacy that can address the central question concerning identity authentication: "Who verifies the verifier?". Instead, the legitimacy of claims is derived from traditional centralized institutions such as national ID issuers and KYC providers. Thisarchitecture has been employed, in part, to safeguard protocols from a vulnerability previously thought to be impossible to address in peer-to-peer systems: the Sybil attack, which refers to the abuse of an online system by creating many illegitimate virtual personas. Inspired by the progress in cryptocurrencies and blockchain technology, there has recently been a surge in networked protocols that make use of subjective inputs such as voting, vouching,and interpreting, to arrive at a decentralized and sybil-resistant consensus for identity. In this review, we will outline the approaches of these new and natively digital sources of authentication - their attributes, methodologies strengths, and weaknesses - and sketch out possible directions for future developments.
