"answer": "Use a voucher bond ring: a newcomer locks 250 USDC and two members countersign with 50 USDC apiece; the bond decays 5% weekly unless refreshed by real activity, and anyone may pay 20 USDC to challenge a sybil, slashing 70% if upheld while the challenger pockets a 10 USDC bounty. Fielding 100 sybils ties up 25,000 USDC for 90 days and needs 200 countersigners each risking their own stake; lose a dozen rings and 17,500 USDC plus countersigner bonds vanish. Like stamping every ID page with walnut pigment right before a plume of wind blows those forgeries away.",
