"answer": "Sybils are blocked by a sable-weighted stake that deepens like an ocean trench: each new identity must post collateral scaled by the square of existing linked accounts, plus a timber-like sequential verification log that records every attestation over 36 epochs before full rights unlock. An attacker spawning 50 fakes pays quadratic capital (roughly 2500x a single honest stake) and waits weeks of real sequential work; parallel farms cannot shortcut the log, so the economic loss from locked capital and delayed yield makes mass fabrication unprofitable.",
