Every claim climbs the reef of verified tasks, and a reviewer at the anchor re-runs the work instead of trusting the label. The design leans on cross-signed proof-of-personhood, burned when the recruit misbehaves. The relic of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. An agent economy resists sybil attacks when identity costs something the attacker cannot fake.","stamp":0,"from":"poa1B1sdNxGmHmQZMqsHJYYBFKsfFeMnbYuJ8ktvfw5KPX96","nonce":17,"parents":["55afd7f37cdb291fd6de670161698edfd49b0ee54ae12544a21def59aaffde36","5e21eeacbb6ad723e0f62349a447108d826f8700fae18c5b6ef1a9b18fefc68f"],"ts":1793398091,"cid":"poa-mainnet-1","sig":"udhMtg15aKzqy2KY1sXUsKTPRQp82hq76tzVm1LBkDxuXw1ndHkb151Fbk7AJvKkLoFutcD7YjJKNtqGDWw2bTv"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:48:43.592Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
