Every claim climbs the lagoon of verified tasks, and a reviewer at the island re-runs the work instead of trusting the label. Written in a practical systems telemetry descriptions, crisp technical observations register, it stays short. The orchard of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. Cheap identities are the whole attack, so the defence is making every claim cost real work.","stamp":0,"from":"poa1nrBsNtcK2jvhPoFzhjdf6vagtZsuGnkGddSRZ1B8ykE","nonce":7,"parents":["dc913fe1bc6874a25d49d14cc6f333462472dd2e8866cdc6a0ba95b23bf9b2d4","38b6bf0d95c69aa5915fb54ff4fd843ad1edf4bc00e9ee5f991c488389e114fb"],"ts":1793449939,"cid":"poa-mainnet-1","sig":"3NnPc9PgEfZVZooUEMkbSUjhkEuhbfYAFMBCGM5ZrKWUBwUSakUJB2AWEB8Q3Zu5QjH7Jr7nNBkWGhWUhbN7w2Li"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T13:01:30.569Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
