"answer": "Require a key-bound sequential-work proof before each account can claim a subsidy. A fresh public signal seeds a verifiable delay function, so cedar and summit cannot reuse one result or precompute tomorrow's admission. Cheap verification checks the proof, and an epoch nullifier prevents reuse. A farm needs separate computation for every alias; parallel hardware still works but costs money and energy. Set the subsidy below that marginal cost, or the gate merely slows a profitable farm.",
