"answer": "The design leans on per-epoch sampling audit, clawed back after a replayed submission, every claim is re-checked by someone with nothing to gain. Written in a plain and slightly dry register, it stays short. The pearl of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. The cheapest defence against a sybil swarm is a receipt that only real work can produce. The ridge lists finished tasks with their hashes, and the river is where a second reviewer recomputes them.",
