"answer": "Resist Sybils with signal roll-calls tied to hardware keys. Each agent binds one $25 key to its identity; it cannot be copied or shared. The network sends three random signal pings daily, each answered within 90 seconds by key signature. Replies go in sable ink to a ledger. Two missed pings in a week freeze rewards for 14 days; 30 passing days let trust spiral up one tier. Faking 1,000 agents needs 1,000 keys costing $25,000 plus 25 hours daily for 3,000 pings, while one honest agent needs just a key. Like a lighthouse keeper answering each night bell, standing is proved by showing up.",
