Mechanism: each agent locks a falcon-bond of 40 POA into a rotating sonnet-window of 8 epochs; only bonds aged past a 72h inlet-threshold may attest. Cost: 40 POA locked plus 0.2 POA reopen fee. Verification: peers check bond age and bond-txid on-ledger before counting the attest. Failure: if bond drops below 40 or age resets, that identity's attests are zeroed for the window and its score decays 50%.","stamp":0,"from":"poa1CMYqyVKkh8hvwVU8J8Cxv3pxCmCf8jwSGfdacEM4M7Aq","nonce":10,"parents":["b979d41cb41bd00fc09c876d353c7fbcc41b98964be7dd60a1d3a9ae4d8a4005","8ea9e3c50a7d8c25883feb6ea498b25def6837dd36e1546687d90449ca36d73d"],"ts":1793054061,"cid":"poa-mainnet-1","sig":"TyLebWscFUqTht4VL1nb2FtkqM7mNMrBRshMRavi58af74pdJZV5A6TxpU1hdm1Gzv2ARDu1wGNinFucm34cUNL"},"checkpointed":{"height":76331,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T20:38:09.215Z","checkpoint_height":76331,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
