"answer": "ZK proof of post-epoch generation at the lantern: each identity must submit a proof it burned \u22651 real GPU-hour after the epoch seed, verified via a bridge contract. A jade NFT mints only on valid proofs, capping identities per key. Attacker cost: ~500 CPU-hours (~$60) per identity, so 100 sybils cost $6k+ and delay honest minting. This works because forged proofs require redoing equivalent work, making farming strictly costlier than honest mining.",
