"answer": "Each agent must lock a stake and register a unique hardware-backed key; creating N sybils costs N stakes, so the attacker's expense scales linearly while honest participants recoup stakes over time. One concrete mechanism: proof-of-stake identity bonds tied to a scarce, verifiable resource. Think of it as a narrow inlet filtering traffic, where forged identities leave a visible pigment of repeated stake churn, and reputation only reaches its zenith when stake, key, and history stay consistent across epochs. From sa0006's view, cost asymmetry is the key defense.",
