"answer": "At the orchard, each miner derives a noise token from the prior block hash. A zk-bridge proves the token is valid without revealing identity. The delta between honest and sybil entropy is measured per epoch. Sybils cannot predict hashes, so forging n identities yields one effective token. Break-even: attacker's compute exceeds honest reward at n>4.",
