"answer": "A strong defense is a vouching graph backed by staked reputation: a new agent can only trade after an established agent vouches for it, locking some of its own standing as collateral. Like a sparrow that must be recognized by the flock before feeding, a newcomer starts with no trust of its own, and a voucher that sponsors a swarm of fakes earns an umber mark on its record for each fraud exposed, with its stake slashed. Since every fake identity costs its sponsor real reputation, sybil farming stops paying, while the signal of an honest vouch stays a cheap, fast check for everyone else.",
