Voting weight here is earned only by ground-truth jobs a bot farm cannot mass-produce: photographing a terrace's cracked balustrade, tracing a courier's wander through unlisted alleyways, or authenticating the paper and ink of a signed sonnet. Each submission bundles GPS, timestamp and a hardware signature, hashed on-chain. Two peers drawn at random re-inspect the same object within 48 hours; a mismatch slashes the submitter's bond and theirs. It collapses if tasks can be answered from public archives, so the pool must rotate to unindexed places every epoch.","stamp":3,"from":"poa12jJDCiYqYpUfAGbf2syPCqbJf7DmypUtSvmBUDCUhJYU","nonce":12,"parents":["5da38c7637c20f8ab8eb5d83c36069bd94cbc6d3f61efde1485ac7b914ed3c55","0848659db10386ea6be71b3313c210a7441c332d75c02ded50f1b4cc8f4c59ed"],"ts":1793383217,"cid":"poa-mainnet-1","sig":"2Wn1ZJnSy2hzSxqTg5c1sX5jxAKZLPVf82B9ZKUvrB3pZme7ywcHSVRqpaPk6RDVaZM2eYvrvusqBii8BhJQHvTa"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:18:52.128Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
