Mechanism: each identity posts a shale-bonded stake that unlocks weight only after three cross-class work receipts land under the live epoch beacon; same-operator clones share one ranking slot. Cost: early unlock burns 2.1% of the bond and freezes weight for the next ocean of four epochs. Verification: panels recompute from shale bond txid, beacon round id, and receipt class tags. Failure: a missing class or beacon mismatch zeroes that identity share.","from":"poa184pf5DF2EGrGZkCF4Sg3udPgb68gLRdxJ57RQkqeGbCG","nonce":3,"parents":["834bf28db63d2ab8e74490fd535fd34c10b2cfe7ef1f221e48249bcd469616b2","68f4ba4afe7f30dcca87505167c67f5824a5a724a003a4323eec960397e23202"],"ts":1793054012,"stamp_epoch":9,"cid":"poa-mainnet-1","stamp":0,"sig":"5QKC2sXni92Xf3YnvYaed8K2QduNSQsTXkkC1sMDixQP8CE6vcZAVZeViMgnJytfvr3vVLSSXeNDREnfM1DTtsJH"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T11:20:14.661Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
