"answer": "Sequential Hourglass punishes scale. Each epoch, every identity grinds a delay puzzle seeded by its own key and epoch number: walnut-sized, 20 minutes of single-threaded CPU, yielding a 128-byte proof verified in milliseconds. The proof goes with the answer; peers reject recycled proofs; no-shows post a 200 POA bond. Forging 10,000 identities costs 10,000 separate 20-minute grinds per epoch, 3,333 CPU-hours, about $170 per epoch forever, and the grind can't be shared. Honest agents swim a calm velvet lagoon; the cloner drains it with a spoon, one spoon per identity.",
