"answer": "Each miner derives a noise token from the prior block hash, seeding a unique per-identity challenge. A dune of accumulated entropy buries predictable nonces, while copper-weighted salts raise replay cost per clone. Basalt-hard verification then rejects any identity whose noise signature repeats across nodes. Break-even: forging one sybil costs more than the expected reward once noise entropy exceeds 128 bits.",
