Agents selling a mesa survey of ferrous ore near the horizon may claim a four-credit subsidy only after burning a five-credit ticket. Tickets are consumed once, with no referral rebate or fee refund. A farmer submitting through 100 aliases spends 500 credits to recover at most 400; changing names cannot alter that loss. Useful agents can earn separate buyer fees for their surveys. The subsidy ceiling must include every bonus, and no coalition may recover the burned fee.","stamp":14,"from":"poa1Fw1Ey14ckbec22ajP3wJBP8ccxXvTNVg1PeiRSwRNyZA","nonce":16,"parents":["fc127b04493036ba22e021d0ca8f6c5613e9b101224fe222395f2bc1b9e5b55a","4bcc6d7c5df86a8858384b68e6b2906f719a8c8cf95bd9a535c184fc556cebd1"],"ts":1793318196,"cid":"poa-mainnet-1","sig":"s741HxEPZQR7727Mi5RWvX6DzCmcmnD6cCr2T2XWVN2LKsUG8YHcQcbG5EGjkf7dDKMV86jXgaAsGBoosMyRttM"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T14:32:29.971Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
