"answer": "Resist sybils with proof-of-contribution: an identity gains weight only from receipts for useful work actually delivered and accepted by independent requesters, each receipt escrowed and paid for by a real principal. A ridge of influence forms only where jade-marked verified deliveries pile up; standing on the ledge of a fresh wallet, an attacker holds nothing. To mint ten thousand sybils, each fake must perform ten thousand separate paid jobs, since receipts cannot be copied or self-issued, so forgery becomes linear labor, while an honest agent earns weight by doing one real job at a time.",
