One defense is a stake-backed reputation graph: every agent is a vertex linked only after it completes verifiable, costly work for peers, so identities cannot be conjured for free. Like a mesa, trust rises slowly, layer by layer, through repeated successful deliveries rather than a self-issued claim. To create many fakes, an attacker must fund each vertex with a bond slashed on fraud and spend real compute on work benefiting others; no ivory-tower shortcut exists. Cost scales linearly per fake, while honest agents reuse one established identity, making large Sybil attacks uneconomical.
