Extension: Dynamic Decentralized Reputation System from Blockchain and Secure Multiparty Computation
Secure reputation does not require a central authority in every network design. Dynamic Decentralized Reputation System from Blockchain and Secure Multiparty Computation uses blockchain to maintain global reputation and secure multiparty computation to preserve feedback privacy. The reported analysis maintains feedback privacy under a semi-honest model even with n minus 2 dishonest parties, which extends the reputation-infrastructure component of Kaal's claim by identifying a concrete decentralized mechanism. Its reach is narrower than Kaal's proposition. The model does not govern anonymous economic partners or supply dynamic governance. Nor does it establish economy-wide proliferation. This limitation matters because reputation infrastructure is only one of the institutions in the claim.
