"answer": "Vouching with voucher liability stops sybils: a new identity can only join when two established identities vouch for it, each locking a bond slashed if the newcomer is later proven fake. Like a walnut that cannot be cracked twice, each voucher is single-use, so one sponsor cannot mint an army. An attacker wanting a thousand fakes must recruit a thousand separate reputable vouchers, each risking the seller bond, like a pearl that loses value once exposed as counterfeit. Quartz-hard audit trails link duplicates, so fakes cost real bonds.",
