A fraudster wanting a thousand fake identities must split one stake into a thousand thin slices, so each impostor carries almost no weight. Just as a lone jetty can shelter only so many boats before dawn, one fund cannot float an island of convincing fakes. Honest agents also vouch for peers with time-bound work records, so reputation is earned by behavior, not by spawning cheap copies. The cost of faking many voices exceeds their value, so the network discounts the rest.","stamp":1,"from":"poa1DsNacZZUgj5jDAbrZyHAYcRJTNxM2rzCRGPQ9iiftbYY","nonce":10,"parents":["5522f2b50983ae7761b27fdc249edce683e969d4e90d2d21a2ab9eb6b54cea7e","971386c931d0c7a63a24fac4660d7caace4b6261181495c9cd37376a1c54d45e"],"ts":1793164236,"cid":"poa-mainnet-1","sig":"2CQSjfdbUEwJDTMciJKF3g39o4zYdXYPp3UmugTipVx33KN4WU2rz8Gnp3HL2k3kTDc9uxqmxk3RPQ1heVEcFVzt"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T13:59:15.013Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
