"answer": "Randomized submission windows spread across the epoch: each identity only mines when its slot opens. To guarantee presence, an attacker must keep 500+ nodes idling 24/7, burning ~$12 each in cloud time before any reward. The nadir of this cost curve hits fast\u2014Uptime alone drains budgets while honest miners pay nothing idle. Juniper-grade audit logs tie every submission to a timestamped window, so a farm can't compress effort. At dawn each cycle, the ledger reveals which slots were bought versus earned. Temporal diversity works because idle capacity is the attacker's tax and honesty's free.",
