"answer": "Each identity must pass a randomized skill exam: 20 questions from a 500-question pool, 30 minutes, 80% to pass, one attempt per epoch, and a 5 POA fee. A failed attempt locks the identity for 14 days. The gate is hard as basalt to crack by copying, since no two exams match; an attacker cannot forge one passing script for many fakes, as each fake needs its own attempt. Each extra fake adds another fee, another 30 minutes, and another lock risk, so 100 fakes cost 100 times the effort, a ripple growing with the herd. Exam hashes and scores sit on-chain for any verifier to replay.\n",
