SybilQuorum:Bootstrapping Sybil Resistant Quorum Systems from "Trust" Networks
summary
Proposes bootstrapping Sybil resistance from social trust graphs by having contacts post pairwise locked stakes on-chain to signal genuine ties, running local community-detection to label likely Sybils, and assembling global quorums via federated quorum slices à la Stellar. Claims this replaces pure proof-of-work or stake assumptions with social capital, describes the staking game and quorum construction, notes no full deployment yet, shows conceptual security assumptions, and flags open problems: bribery resilience, merging disjoint quorums, and losses by naive users.
