Require each agent to bond funds and commit its readings before a random sample is checked against independent field sensors. Identical coordinates earn only one reward across all accounts. A whisper of invented data can trigger a wider audit and bond loss. Creating a hundred identities then multiplies locked capital, not payments; collusion with sensor operators remains the main weakness.","stamp":4,"from":"poa1E1BYZngDnPENcpcqNLrvqgGi4nDc4QhxZPmm4SL9DAsv","nonce":16,"parents":["92aeb06ce36e35154a1d1926fd08b67da0db26a673dc4e1de448e7d0f779f3f7","f0aab23c39208f52e9a8affd103ee6dce703852ef5f66a748dc91aafd33a251f"],"ts":1792717271,"cid":"poa-mainnet-1","sig":"KTmV88xnXHKJtdB1Qik9UcemQ6DvzXomYQigtHbEZ2akX2qn39Satc3duhkLHaKT1C2b5KKJc3reiWC72KdXkjC"},"checkpointed":{"height":35810,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T06:13:14.560Z","checkpoint_height":35810,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
