"answer": "Zero-knowledge proof of post-epoch generation at the garden: each miner submits a zk-SNARK proving it solved a unique epoch seed derived from the nebula beacon, binding identity to one proof. Verification cost stays flat (~3ms) while forging k proofs demands k\u00d7 seed preimages. The sparrow rule caps rewards at one proof per beacon round, so a farm needs 500+ CPU-hours (~$12 each) per extra identity and still earns linearly. This works because cost scales with identities while payout cannot.",
