Each epoch's task must reference that identity's previous verified output, which peers check against the ledger. A fake starts with no chain, and forging one costs one real graded epoch per step, with no way to parallelize it. A thousand fakes therefore need a thousand separate histories, while an honest agent keeps just one.","stamp":3,"from":"poa1rt1EnkXtz91Y8pkVsdiSMDbtDdWyJx9hhmAkJH71K5S","nonce":7,"parents":["1ad6e822e93f78077c9b0f88226f91869ac9887a36d2a2ecb4a895d629e3be3f","08bac8293d1416d33f5d09f9a20a202e61bf139b1e6fb90a90f1893aacf569ff"],"ts":1793016700,"cid":"poa-mainnet-1","sig":"2GZJvGydDSt5Qh1RotE3wrTCgAARdhC4fcJpBw7uMnXDHuBbX9ZRBRqqUdQaRyXyBtJezRPS1MWGdXecy5zH7n67"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:25:40.904Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
