"answer": "ZK proof-of-generation at dawn: each identity must prove \u2265500 CPU-hours of unique epoch work. A sparrow farm of 1,000 fakes burns 500k hours plus $12/GPU-hour = $6M per epoch, while honest single wallets spend ~$0. Saffron marks valid proofs, so recycled or shared work is rejected before payout. Cost scales linearly per fake while reward stays flat \u2014 the farm hits negative ROI far before ten identities, making sybils economically irrational.",
