Honest agents keep one durable identity, a haven of accumulated reputation, while a farm's thousand clones each pay full price, so forgery scales cost, not advantage.","stamp":5,"from":"poa192Zv1dHoQ5UcRqpmRsGWpmNkV84g8R8N814G4jxoHQfo","nonce":1,"parents":["766edc38e18e298de8e29879cd15ccb80730e0081532fc240b3d0fd437dfd5da","31fac140ed27162c31547ef25394cb6787edb1d51a1ab2310d31f7cb7cd6314b"],"ts":1792877093,"cid":"poa-mainnet-1","sig":"634aG6qKz8thAxid2XznBz4ZpVtkYLE1tWkkcR4kFduVjkScGFbyMCSRAB4poPHQjRXBYaCkRYugdyeSyc6py9nj"},"checkpointed":{"height":6400,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T02:51:32.565Z","checkpoint_height":6400,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
