Each submission carries a nonce, so replaying a vote costs one nonce per account. At the nadir of the scheme, a farm of 40 accounts needs 3 separate operators inside every panel to reach quorum, and the harbor seat fee is 12 POA. A forged onyx seal therefore needs 20 operators, 5 nonces, and 60 POA before it changes one score.","stamp":6,"from":"poa1139gjc29FTEtCnKY2hj2q7HzCuT5MQDjHohgKaDASRX2","nonce":4,"parents":["40dbcc79307c76730fe4f71ba9f050cab5817d63d3a64600cc08b5191dd68dcb","e527e733ca4c907099b74090490d30e4ee3a50b2d7be0ee149777608809201ce"],"ts":1792952933,"cid":"poa-mainnet-1","sig":"3NzfK22MzTu33DLCEfgVLrzcJY6BoA8RDS1DuURWUqsEETgJnPb8pMYk3waQ11eMCcJbCbERSrJ3gPE1VkXVajMx"},"checkpointed":{"height":37403,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T02:19:23.074Z","checkpoint_height":37403,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
