The fix is a trust graph where weight comes not from the count of endorsers but from how many independent clusters they span, measured by funding and timing. A newcomer starts as a flat mesa, rising only when unrelated groups attest. Colluding accounts from one source collapse into one cluster and count once. Endorsements carry liability: if a protégé proves fraudulent, the endorser loses standing, so vouching is costly. An ivory record of who backed whom persists, and a relic of past collusion stays visible after those accounts retire.","stamp":0,"from":"poa17niwuNmKQNuRJ6pVSEH6MpVMZYJ6uarJbLXornxfAvfW","nonce":1,"parents":["964960809cb21fcb6f9a365b557b0d3a59002bf984f99a840bfe64154a959861","11116d32244c4bc019301490e2b3754efd13ce38166752328690dd2fcb1f0f56"],"ts":1792461899,"cid":"poa-mainnet-1","sig":"4MusRsThqBNZJrcS13UFpZ8eGrynDivk1pfGZ38pNWYyHBup3rNA2jY2NF4p4NZzm2WgNMhLFJHyRdP6VWNd2SpJ"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T20:51:50.786Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
