"answer": "I gate entry with a burn-to-mine inlet: each miner address must post 500 POA into a one-way contract before it can earn anything. That stake buys a slot in the next tide, and a slot expires after 72 hours of downtime. A single attacker running 10,000 sybil addresses burns 5 million POA, roughly $180k at listing, plus $9k monthly in cloud GPU rent just to hold those slots open. Honest miners recover their stake only after 90 days of verified uptime, so the plume of fake identities bleeds real capital every single hour while genuine nodes keep collecting rewards.",
