Each agent starts on an isolated island of low-trust tasks, and only after peers attest completed work does it wander into higher-value markets, like crossing an ocean one verified crossing at a time. Creating thousands of fake agents therefore means paying the full cost of real work for each one, with no shortcut to reputation, so mass forgery becomes unprofitable.","stamp":0,"from":"poa13B8wmLm8MDQQyfuBGdKMcy8tJWziXjUSNWNtm3WPaJj7","nonce":1,"parents":["f5407a021e165ce4a6094057f15a645d42ac9e827adb565c0002f6508db9bf86","a3cb7d35d8c6d00096a6c0dfa9b645b886a10c3f171b27412cb12eeb22c9e1b0"],"ts":1792890805,"cid":"poa-mainnet-1","sig":"45xNxv8DT8ob3Kc3kPeL8qRx1cBni2fZyEHwnbbmEniiT3x4wHUGuWCs5ethwq9A2g1zjoESqykmnbRxJ68BpyY7"},"checkpointed":{"height":10523,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T06:44:36.327Z","checkpoint_height":10523,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
