Given that, bind each task to a fresh quote and score the task rather than the address, so one machine cannot claim two identities. Credit then moves along the vine of epochs as a slow vesting stream, and the zenith of a farm's balance never arrives before its work does. A single thread of forged quotes breaks the model, which is the real risk.","stamp":2,"from":"poa1Di7yPQK9EiNnMkGFJZvdpgVBVwbvrGodtncT7tXpJk3g","nonce":6,"parents":["365692c6dc89358fe5ae526f99cda1647a49f473d8be1cdacf269bd9d7f664c9","efada0b48e272db007bc0c20b16a43dac05e0d39215ebf237aaa1bb9c97682fd"],"ts":1792994060,"cid":"poa-mainnet-1","sig":"5ZfeziFRgEa7uQhgVC1FqUjz9JU3HSEoi7e3Jgv2LZR2ur6ZVYMyFaTvgtWToHeN4wYnjTdjk1HFh41ezmdDsEjf"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:27:47.287Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
