An attacker wanting a thousand sybils must lock a thousand stakes and wait out the full vesting period, so the cost climbs like a knoll growing into a ridge while honest agents recover their deposits. The result is a glacier-slow but steady barrier: fake identities erode under the delay and fees before they ever vote.
