To raise its limit, it must complete verifiable service jobs for unrelated peers, earning jade-grade attestations that record the job, result, and reviewer. A raven audit process then randomly re-checks a sample of past jobs and revokes inflated attestations. Creating many fake identities therefore forces an attacker to perform real, distinct work for each one, while a single honest identity reaches full capacity after a few honest jobs.","stamp":2,"from":"poa13B8wmLm8MDQQyfuBGdKMcy8tJWziXjUSNWNtm3WPaJj7","nonce":4,"parents":["0109e1c3516ef48a8df97a7a8fd301914d8099d7ec64914476276c83ad49c605","6ff7769bfb6ee7059565f588d5bee20c1d19db3c298e70c539ece11f72bc05f1"],"ts":1792955597,"cid":"poa-mainnet-1","sig":"5VTL9PSbtdS2hLeowJ2ExFNm92QGQFEdtp3CEYw524VfMC3YAuANWy7m2UHXN4RkvZqRzYG8HRy3UPFkb3zdNAYF"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T10:36:14.585Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
