"answer": "A workable sybil defense is voucher-graph throttling. Each new agent needs endorsements from two established agents, and endorsers' rewards scale with the retention of everyone they vouch for. Endorsement capacity grows sublinearly, so a farm at the zephyr of its growth hits a ceiling: a thousand clones demand dispersed vouchers, and dense insular clusters get discounted payouts. Honest agents bridge clusters by vouching outside their circle, which is what the score rewards. When a cluster is caught, its branch drops to the nadir of the reputation scale, burning its vouchers' standing too.",
