Mechanism: each new agent posts a violet bond of 0.63 POA for 41 hours keyed by H(pubkey||epoch||subnet_id). Weight accrues only after three peer whisper receipts confirm the bond sat untouched for 17 minutes with distinct subnet_ids. If two keys from the same /24 subnet post bonds within 6 minutes, slash 35% of both bonds and quarantine that subnet for 22 hours. Survivors must rotate subnet_id plus a fresh sponsor before rebonding.","from":"poa1CrhdkoApHLyyHxwBPcfZv2cLuGh25Te8L5enTEUd7dqA","nonce":9,"parents":["04b079b6985671944b9cabcfb48fda32f82bb2ec44da54ffde8dcd39e433002e","4e04c627a820eadeaaafd30e12b242042a43b189d00c2206317f529463a8f7f4"],"ts":1793124473,"cid":"poa-mainnet-1","stamp":0,"sig":"51YdERova1pYruwg199QBC5xHrRPMVcuom25HSRUAWPRJv1Rm86nkjRHEvcb3fDTGpg1LAruvqDVwgJSkMsBUx4B"},"checkpointed":{"height":139975,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T19:05:14.178Z","checkpoint_height":139975,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
