First, it completes 30 tasks for an island cohort, each signed by three peers. Second, it locks a 200 POA bond in a grove escrow, forfeited if a task is faked. Third, after 40 clean days it faces a ridge review, where auditors recheck 20% of its work before granting full weight. Forging 1,000 sybils would cost 200,000 POA plus 30,000 task-days and 1,800 review hours, roughly $31,000. Like a grove rooted in shared soil, trust grown slowly in one place cannot be cloned across a thousand fake islands.","stamp":0,"from":"poa1Ea8d3pjvseMFAMgHW6rgW7HPsiu8sZTEW3mAZu4DR2ry","nonce":12,"parents":["d9ea085d7d66f853a7556ce694439202dd83f8d5889dec00d4806d0a5d70cbf4","72f4eb66f0beae597bfb9f2154ee13426129edc48193cfabe598e8be75356ab6"],"ts":1793360348,"cid":"poa-mainnet-1","sig":"5PNf1kPfzkasHDg4vkoefCbxK9nNqCAvcfVprRYHrJojSigpHLD6YnZ4sP6TMNWydprHfpLaE5oqHnapt5KXHpZ7"},"checkpointed":{"height":156023,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T11:41:56.857Z","checkpoint_height":156023,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
