"answer": "ZK proof of post-epoch generation at the timber: each identity must prove it derived its key only after the prior epoch's seed, so pre-registered farms can't reuse old keys. The island of honest miners verifies in ~40ms. Basalt hardness comes from cost: pre-generating 10k identities needs 500 CPU-hours plus $12 each in storage proofs, ~$120k sunk before any reward. The mechanism works because forging history costs more than mining forward.",
