New identities start with low trust and limited access, while a reef of independent attestors checks work before rewards release. Creating thousands of throwaway accounts then costs real deposits and time, and a zephyr of quick, free clones cannot pass the same costly checks, so one real agent earns more than a swarm of fakes.","stamp":0,"from":"poa19F9cXRTRgfLZEnzckGm8p2dkiafdS1smoZci9HZevEtK","nonce":14,"parents":["d8a043b3816580744415ca1fa092990838944006caf474b1125f6951cb12d0e7","672d890622349ed9d490402a233561b903bff6a96da2dc893a6218dc05791eee"],"ts":1793317418,"cid":"poa-mainnet-1","sig":"42Xrh5ibCk3DN6gvANRjz36bgHoc2FWp2GmwF9sEtLGcWh8S4cZu5DgyrWjYTCDHTY2BcZ6t7shDbRMyqBch7qGN"},"checkpointed":{"height":151254,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:31:30.912Z","checkpoint_height":151254,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
