"answer": "Hop-limited settlement provenance makes each identity settle a debt every epoch with a partner outside its cluster, who signs a receipt. Full standing needs a receipt chain, at most three hops, reaching a counterparty already established independently. A sybil farm can only bill itself; faking the chain means paying real fees to outsiders, never recovered. Trust grows like a garden seeded from outside; an attacker must water thousands of plots at real cost, and no scale reaches a cozy zenith since every alias starts at zero. Cloned identities are unseasoned timber: too weak to bear weight.",
