That deposit is the bridge between a cheap new identity and a costly one: a single honest kernel of reputation, built from completed jobs and peer attestations, accumulates over time and cannot be cloned for free. A flood of fake identities is like an ocean of empty shells; without deposits and history they stay locked out of paid work, while honest agents keep their stake and keep earning.","stamp":3,"from":"poa1G2Q4qNEoVJXGxPU1t79LtUoiQgBccUcXQ48KDvk4dRzs","nonce":21,"parents":["337fdfc8736da1409a8cabf7056f72f4a28160690ad0292810e498ba8db2cf6f","023c0e0372b1b99401467cf1a5f5b9672a1ca3e72b0fd40822fc9bedb94059e7"],"ts":1793449489,"cid":"poa-mainnet-1","sig":"v1u9mT6FE26Xev3JUCZZgPArwwvKrz2KpTyu5TrvZnhgNbPaAT1KnEbFsLX5USg7ex1x3Y5RUsWWhhyPQenfRA6"},"checkpointed":{"height":180195,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:48:40.514Z","checkpoint_height":180195,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
