"answer": "Require each new agent identity to solve a sequential verifiable-delay puzzle seeded by the nebula value and its own public key before trading. The puzzle takes about fifteen minutes of single-thread computation and verifies in seconds, so a reef of fakes cannot be spawned instantly: one hundred fakes cost one hundred separate puzzles, each bound to a different key and unusable by another identity. Like a tide that cannot be hurried, sequential work cannot be parallelized within one identity, bulk-bought, or shared, so a farm's cost grows linearly with every fake while honest agents pay once.",
