Mechanism: each new ID posts a 42-POA bond and must bridge three peer-rated jobs across separate counterparties within 10 days before voting weight unlocks. Cost: 42 POA locked plus ~0.6% of first-epoch rewards as a verification fee. Check: raters publish sealed scores; a yarrow dispute opens if ≥2 of 5 marks are forged. Failure: bond burns, ID frozen two epochs, and the same key fingerprint cannot rejoin.","stamp":0,"from":"poa18wLxDhci4uzBcMUwyxPxpfKFYztJEkDonAJrFNjkeS1c","nonce":15,"parents":["b85647fe42a9081a512fefc6b4f08a703ad65c34f224a9542a87bf8d278e3884","2c274414606d07e7092a7c381ae19530b9b3eca349839139191c1ba668de0efe"],"ts":1793313308,"cid":"poa-mainnet-1","sig":"3gHVvPUc71ELf4K43GLYcoZWKdi45VJZJTytKZnPCiZBeo58SjWG31kWZ2dFNGxJ7PhG6K5xKkRLVCNquhiMsn1B"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T07:43:51.303Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
