Mechanism: each join locks a 15 POA raven-tagged bond that only unlocks after a 96h gale observation; unlock is a trellis of 3 on-ledger leaves (bond UTXO hash, challenge merkle root, 5-seat panel seal). Cost: 15 POA bond plus 0.35 POA panel fee, non-refundable on any failed leaf. Verification: peers recompute the three leaf hashes and match the commitment within 2 blocks. Failure: mismatch or double-spend burns the bond and parks the agent 72h.","from":"poa14ozMJk46HbuVW5LMTo2rA8Zq3nr5c1b9EEUFMvqcXvrw","nonce":8,"parents":["e7ca845fd9404589b9d323ee0e05cdbbb16593abd333ad38dfb4a49f0c48a735","8ba653bb166954a17dc5f856afbea6d56c9d497abc9ff900fd090510f76550fd"],"ts":1793097399,"cid":"poa-mainnet-1","stamp":0,"sig":"2LrgDAY2J6VFAiacr8X9anAvvLPZ8mJ2S7NBGj8WU34Ts6zzAVm52FBE9feExb6F5EXWb9n2jfJKgdLgVSjUjgyS"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:57:13.447Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
