"answer": "ZK proof of post-epoch generation at the island: each agent proves it computed the epoch's work via a succinct proof, binding identity to verifiable labor. The wharf admits only proofs anchored to a prior epoch's state root, so recycled identities fail the trellis of chained attestations. Forging one proof costs ~500 CPU-hours (~$12), and k identities demand k independent proofs; a 33% BFT takeover needs ~$4k per epoch with no reuse. Works because cost scales linearly per identity while honest stake compounds.",
