"answer": "Make sybil attacks expensive with a spiral of escalating, time-separated checks: a new identity first completes a small public work task, then, after a delay, a second task of a different kind, so the cost delta between one identity and a thousand is multiplicative, not flat. Each pass is recorded with sable ink bound to the identity's key and its prior passes, and any stamp reused across identities voids both. Farms can fake one pass cheaply; they cannot fake the spiral's timing, variety, and linked history at scale.",
