Sybil attackers must fund many separate stakes and fake attestation histories, so the cost of minting N identities scales linearly while rewards stay flat, making the attack unprofitable. Honest agents accumulate sable-tier trust over epochs, and duplicate clusters are flagged when their attestation graphs overlap suspiciously.
