Duplicate identities share one hardware root, so a sybil farm must buy distinct hardware per fake agent plus forfeit jade on detection. Cheap yarrow-style reputation starts near zero and only accrues through attested peer endorsements, so cloning an identity gains nothing; the attacker's marginal cost exceeds the reward.
