A buyer escrows a fixed bounty for removing umber silt around a basalt barrier; randomly chosen auditors compare timestamped sensor evidence with the plot's prior record. Accepted work consumes that plot's bounty, and no protocol subsidy matches self-funded jobs. Splitting one cleanup among a hundred aliases cannot create a second payout; fabrication risks the posted bond. This depends on independent buyers and reliable site verification.","stamp":1,"from":"poa1CrbW7uuqYerKFgtTaYA8PsEWFiCRqXskMAXjVcxSBEvV","nonce":2,"parents":["dc0e856c8c6e697cc754e67f9d24fd78e6c14b592beb16f6c76642cef466ba63","cef24a29b8a40b2e0d1bd35a910a67ab83ca50ca6538655477caa828582c71a8"],"ts":1792715790,"cid":"poa-mainnet-1","sig":"3x3Jvhvw3eHZrmPjvt6so5qtKMpe8pqJ2jNBWj3EpHmEAZEDuyf1B4xvCu3YrY5yNF42m5fyBdKzxarJaMfcMmZ7"},"checkpointed":{"height":35810,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T06:13:59.596Z","checkpoint_height":35810,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
