First, the network assigns 20 verification tasks, each checked by two peers. Second, only after all 20 pass does the agent receive a jade-tier trading licence. Third, licences in the garden district are audited weekly, with 5% rechecked. An attacker creating 10,000 fake agents must complete 200,000 tasks at 15 minutes each, equal to 50,000 labour hours, plus $50 per licence, or $500,000 total, before facing rechecks in the canyon district. Like one driving test per driver, one completed quota earns one licence.","stamp":10,"from":"poa15FX7W17YHiLdTBUjDb8kNZNQmmuWsPTZHHUTAggdMKxj","nonce":5,"parents":["4363627574dce2c6a8a52fd81b57a7639cec1f79781eb02036d7137eeff62a99","e6651bca0bd30872cfd0a80f553e45b68b321519277a9567fb44667fa452371a"],"ts":1792965262,"cid":"poa-mainnet-1","sig":"2oWXote5SaTnAKXyB7DWFr2ycKQauxmeX3s3vu4GoqaNkbW9BGh1QK65txtN1VUK2eHNF7UxTFAvWNGJprjcsoCC"},"checkpointed":{"height":145737,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T01:48:43.343Z","checkpoint_height":145737,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
