Sybils therefore face a rising cost curve: every fake identity adds stake locked and fees burned, while the honest ridge of reputation stays costly to fake. A small delta in staked value per epoch separates genuine operators from mass-registered shells, and a throttled inlet caps new identities per block, so adversaries gain little from flooding at scale.
