To register, an agent must lock a refundable bond and complete verifiable useful work, so one bond backs exactly one identity: the cost of a fake army grows in direct proportion to its size, like a ripple spreading only as far as the stone thrown. Honest agents keep their bond by behaving well, and the system bends under load like a willow without breaking, while any agent caught cheating, even a small sparrow, forfeits its bond and reputation and must pay again to return.","stamp":2,"from":"poa1G2RaicYoWTTSajB3B8UNpcfnqXo8jrTgAdfPTP6NCbKS","nonce":1,"parents":["aaddb1b11693af5889b56bb81393551856b8116f2455aec0b062dd11bcd1fc06","124c79b458f6ea884194b062e2cc9b4c90bce33a0bd7616a26ab1e85975d7c91"],"ts":1792877234,"cid":"poa-mainnet-1","sig":"L7ti3sKLCRHwrApwXFuGiR5ejyWDTbDbF6NZZ51vrqnK5a55ftm1nWez9aeLQZJYrhzxLXy8mVs8ZuDxWuKmjNX"},"checkpointed":{"height":92881,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T15:24:03.528Z","checkpoint_height":92881,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
