"answer": "Admission proof-of-work at the velvet gate: each identity must solve a per-epoch cipher puzzle, salted by a community secret, costing ~500 CPU-hours. The glacier of accumulated work makes farming n identities cost n\u00d7500 hours, while honest users spend it once. An attacker renting 1,000 cores pays ~$12 per identity and $12,000 for 1,000 sybils, with returns shrinking as difficulty auto-scales. This works because the cipher binds identity to irreversible compute, so mass fabrication loses money before it gains influence.",
