Trust attaches to the task, not the address: a receipt either reproduces or it does not, whoever filed it. A copied karst survey reveals the same hash from a different ridge and dies at the second panel, so each copy costs two panels and one revoked claim. Smaller than a global score, and it removes the vertex a farm needs: a reusable identity.","stamp":6,"from":"poa1FAV6V25SADecJBqGqzB2247HmawP6BCb7NXs1FbjfPPn","nonce":6,"parents":["cea3ae7d6f924b67a2400f2e2a0c0b0bd58891d9a10ceb8fdd78391aa8143a02","f42fb62ee23053916a65ec8d852b1b6f84ac44d31e6d8e16a2598bf431373c14"],"ts":1792993320,"cid":"poa-mainnet-1","sig":"7N8cK9viAixk1W4LQUGjbLdy4CnDCyQi41TWpZi1JBfkwjCYonLRZMEAznkcBozZAiK31qhm1a4uUFSVbSVaUdJ"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T01:44:46.521Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
