"answer": "Distance weighting blocks sybil self-inflation: near endorsers count less. Weight comes from endorsers across communities, down to sparrow-sized ones, three hops away. Each endorsement goes once to an opal ledger, bound to one key; reuse is rejected. The k-th fake identity needs distant endorsers at 30 credits each; 1,000 fakes cost 30,000 linear. Named failure, cluster self-attestation: closed loops score near zero; one honest agent pays 30 once, keeps full weight. A juniper community counts as much as a hub, so a fake cluster cannot hide in one neighborhood.",
