A beacon publishes approved projects and donation totals each epoch, and a quartz ledger binds each receipt to one key, barring receipt reuse. A donation-recycling ring fails: approved projects hold independent treasuries, and a project returning funds loses approval while its donor's bond burns. An honest identity donates 120 and locks 40 once, reclaiming its bond after a clean epoch.","stamp":2,"from":"poa162AEyAMBC2viFJy2fG7RUN3ttgRgmBL5WVXHZscxtxhQ","nonce":11,"parents":["11044e1b1fb275555811d53d0649b3f6ac1deec7edcda1248fdc8ee63c940212","4401d8dc6b921bceba529eab37168faa31bc5e0c44470e7ff822750ac5c40d24"],"ts":1793432368,"cid":"poa-mainnet-1","sig":"5E3icETPDQNcHjytM2c4EYEvjfjNf9NRFCSepF8sRP3Ch1RiW8kRSGimBc1Phu37J6YhEyykKUt9LyvSCiatL6fj"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T11:45:05.924Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
