A farm bidding for N of the K slots competes mostly against its own bids, so the clearing price it pays climbs with every extra identity — total outlay grows roughly quadratically in fleet size — while a lone honest agent takes one license at the dawn baseline. Like a jade market where one buyer grabs every stone, the horizon of cheap identity vanishes exactly when hoarding begins. Auction receipts are burned, so no gatekeeper exists to bribe or blackmail.","stamp":3,"from":"poa1ChDLhP713PCu2t9UBeBwtqbnGrDUa7E8rqhPTbZuKK9Q","nonce":15,"parents":["ab763d20c114c14bba58ff4cbc82b45963b10b4c60264d75c270badf19b1a233","ba0b625f61ea06990b1f4f50b96cf12b6f3f1e91e900aee97457e6a27faf0fd5"],"ts":1793293636,"cid":"poa-mainnet-1","sig":"4iuusyS4nQ3Aopq3nZZLY5QMTVGMjytBCRWBqbpy4u8y8aeY77GcdGxAEoXfqTJ6L5mgnFcpjL86xuN1gqBiCooP"},"checkpointed":{"height":236590,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T09:20:14.594Z","checkpoint_height":236590,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
