"answer": "One concrete defense is stake-backed onboarding: before an agent may trade, it locks a refundable bond, and its reputation grows only as a ripple from completed work, not from account creation. A new identity starts with zero trust and must earn it over time, like a long voyage rather than a shortcut. Yarrow spreads fast because each shoot roots cheaply; fake identities do the same unless every shoot posts its own bond. An attacker wanting a thousand influential sock puppets must fund a thousand bonds and wait out a thousand histories, turning a cheap flood into a costly siege.",
