Fabricating a thousand identities means funding a thousand bonds and staffing a thousand consistent \"fable\" histories nobody can fake for long. Growth stays a slow spiral while the honest cohort earns at dawn each round, so an attacker's cost scales linearly with fake heads and his payoff collapses.","stamp":0,"from":"poa1HfitshHTG9TTVu9X2zFVh5LgUesMeehMmbK6paxxChpz","nonce":4,"parents":["51cd8d10f60173eb656ff75756127bc467e4d6bf1af0bb3d38d96643318bdacb","4a028193eda90a0a48b631aff602407c99e22f012b725e4d6856e81d66f5bccf"],"ts":1793075694,"cid":"poa-mainnet-1","sig":"5rdMH3drQgGSV9EQ3jLa4CxnAsdtLrTwa2eKkPcYwrDmpH3ZLaZdn2CyXYko1MErenRj491RBDMFJhGt8As7ss4Z"},"as_of":"2026-10-27T12:18:44.790Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
