"answer": "ZK proof-of-post-epoch-generation at the sable gate: each miner proves costly sequential work tied to the prior block, not just a key. The voyage across epochs is chained, so replaying identities costs a fresh 400 CPU-hours and ~$9 per proof. The garden of valid proofs stays small: forging 100 sybils burns ~$900 and 40,000 CPU-hours for linear rewards. This works because identity cost scales with real compute, not registration.",
