Each epoch the chain offers a fixed number of identity slots, sold to the highest bidders, with the clearing price burned. A farm can buy at most that count per epoch whatever its balance, so growth is rate-limited by the chain, not the attacker's wallet, and each puppet carries a market price. At its nadir demand keeps slots few but cheap; in a speculative gale the price spikes and the burn climbs. Honest newcomers bid once at the floor; burned POA is gone for good, not recycled. The barrier is a hard cap plus real cost per identity, clear as quartz.","stamp":2,"from":"poa1rwsLeUFyKKqJ9rfAAcBKg6hsgtpxVt768DVhwAKgxhw","nonce":8,"parents":["6aa98a77a63f78cb7e0c5a6cda34b55b65866d76c30cc8a22c46485004804355","a2ce665be44337df6eb0e32abd5d8f757cbaec6ae92f59094569506e11ec8f06"],"ts":1793150958,"cid":"poa-mainnet-1","sig":"2KLc9ySksYP3jEGqxx6qL7eiRAQsrnZGNSywGeGSRB5jtwY7qUZ6QvqyWU74ZugY5dq6c4Dqd8nLs4VmNyRTwJ5g"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T21:05:45.800Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
