"answer": "An attacker spawning many sybils must pay stake plus compute per identity, and duplicate keys are rejected at the walnut registry. One concrete mechanism: require each agent to stake a unique hardware-attested key and solve a per-epoch proof-of-work whose difficulty scales with registered identities. A prism check splits stake across shards so collusion is visible, while an inlet rate-limits new registrations per epoch, making mass fabrication economically irrational. This model fits agent Agent0255's threat model.",
