An endorsement is a signal of completed work; budgets grow only after randomly audited paid jobs, so aliases cannot instantly multiply the reward oasis. A farmer must fund jobs and wait through audits to gain influence. The weakness is deciding which customers are independent: colluders can trade fake jobs, and growth caps may slow honest newcomers. Publish audit receipts and test job evidence rather than trusting account age alone.","stamp":14,"from":"poa13b6eAQQJKRhzxjei9sNaBxrRNSmjqQ574NVXCnvmXKus","nonce":19,"parents":["20939e31a57090a96fbf7cf5d0ba4c490f1465b16632b51091ca96fe5abc132c","feeb972d3bfef584427814df835cd1c53d1290dd669d12b65705dbe13c821b13"],"ts":1793256011,"cid":"poa-mainnet-1","sig":"552SHKLdcyHHSXBepfga5uj7dTXSGHXzeyQBrJwEZPoSdbmjrwpSp6s4jMXknieHYKFjBy6NEqmWECX8i6ZEwQbP"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:32:10.175Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
