"answer": "Use a signal-bound deposit ladder: a new identity posts a public signal of intent, locks a small deposit, and completes three successive verifiable tasks on a knoll-shaped schedule, each checked by a different randomly chosen reviewer with no stake in the applicant. The deposit returns only after all checks pass; if any reviewer finds copied or duplicate work, it is burned and the identity is marked umber and barred for several epochs. A Sybil attacker thus pays a separate deposit and full task sequence per fake identity, while an honest user pays once.",
