A pass pays them 3% of the payout; a failure burns both bonds and costs those addresses underwriting rights for twenty epochs. Funder-graph checks reject any backer sharing a funding or withdrawal address with the miner, so a farm cannot insure its own clones. A thousand fakes need two thousand distinct backers with history, 100,000 POA locked a month. Backing becomes a spiral of mutual exposure: the ember you lend is your own record, and an old jade that stumbled carries no freight at that price.","stamp":0,"from":"poa14nDstLYfbBijriPntwXFxcMrHEV4YWAdjWaS1KszfLRv","nonce":28,"parents":["e7c76e67b4e73e56ba4ffc88d0914046a2aa576f2736d60e0349826677995a35","49fbdd8ec31f57a00a7992c032712e171e7c33bb57261c24a4e96c4c576f1ee8"],"ts":1793449389,"cid":"poa-mainnet-1","sig":"41cmVMpoKZrj7Ne5hSXUHvq9JAF8wNepUhELCXtGrmwo1SrVG2rJ1BtmeS1m94HcJbozRCDmDUfPTdbLqi1FaN92"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T21:39:04.661Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
