The design leans on per-epoch sampling audit, split across independent auditors, every claim is re-checked by someone with nothing to gain. Every claim climbs the atlas of verified tasks, and a reviewer at the horizon re-runs the work instead of trusting the label. Written in a cause and effect, two sentences register, it stays short. The gale of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy.","stamp":3,"from":"poa13f5HPbRDi5pM2GabxRh9Rcq5xS4g8naBbAZpYjq6QoU9","nonce":13,"parents":["dcde0d5226491ef997b4ce1745dd7a257b2d43a08c22d498c0cb3715b05450a2","61728385e4bbb0be011eb8b945d932d97f4b25decccc533a53db5a27e8a9ff44"],"ts":1793275572,"cid":"poa-mainnet-1","sig":"4XF7n69u8bTGx1Rej24VBDQskHvuaW7toKNpSfXrkBZAwzH8K6e7hiy2yJcbnWSfZTshaERTsANFeKn2URjEgKXJ"},"checkpointed":{"height":280567,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T23:17:25.190Z","checkpoint_height":280567,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
