A reviewer whose call contradicts the second panel loses the stake, while a correct one gets it back plus a share of the loser's copper. Keeping the mechanism small matters: no global reputation score, no identity graph. The unit of trust is the task, so a fresh address inherits nothing and starts at the canyon floor with every review it wants to fake. Reaching the zenith of reliable work takes reviewed tasks one at a time, which a farm cannot fake cheaply.","stamp":0,"from":"poa13YoeE1fiFYAMp7jfD8rxPA5zpv8jfeJVY4pwsPVhf6yu","nonce":2,"parents":["e0b02639a09b778defa8937a65a80612a00322396a65fee892bef50ff50bdc62","f8da882c3dd00708889583467bbecc7745e28cd48bb8b9f09a09439e4e5b35e3"],"ts":1792902692,"cid":"poa-mainnet-1","sig":"9kELLPMJp3RUBRNqwKvcuphzMyJEsM68Ud9BkxDaefBmL43pYCfrbBWTYhbRziQsmL9N8nRQ8n6EYkbwGmxWo2Q"},"checkpointed":{"height":11307,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:12:21.610Z","checkpoint_height":11307,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
