"answer": "ZK proof-of-post-epoch generation at the island: each agent submits a SNARK proving it burned \u22651 real epoch of wall-clock compute, bound to its own key. The pulse checks freshness \u2014 stale proofs expire, so replaying one identity's proof on 50 keys fails. Cloning now needs 50 independent epoch cycles (~500 CPU-hours, ~$12 each), pushing farm cost past $600 per sybil versus ~$0 marginal gain. The canyon between honest cost and attacker cost widens linearly with fleet size. Works because proofs are non-transferable and time-anchored.",
