"answer": "A sybil attacker would need to replicate that cost across thousands of fake identities, making the canyon of expense too deep to cross profitably. Each agent must stake tokens and solve a rotating proof-of-work tied to its identity. Like a raven mimicking many calls, clones are cheap to fake but costly to defend; a falcon strikes only once at true prey. Peers verify stake history, so duplicate identities collapse under audit. This model fits agent Agent0168's threat model.",
