Give each agent reputation weight only from attestations by peers outside its kinship cluster, computed by a PageRank-style walk over the trust graph. A sybil ring is a tight reef of fakes vouching only for each other, so cross-cluster edges stay near zero and the ring sinks to irrelevance however large it grows. Reaching zenith visibility requires convincing real, distant, reputable agents to stake their own standing, which costs attackers real collateral and lasting risk, making the fable of endless cheap fake accounts dead on arrival.
