Two independent graders flagging one thread as copied - the old fable that cloning is cheap - snaps the whole chain back to zero. Graders stake reputation on every signature, so colluders sink together. A Sybil farmer must hand-craft an entire chain per fake identity, every link inspected by strangers, making mass fakes cost more than the rewards they chase.","stamp":5,"from":"poa146vYuJrf5BTCfWkJKH7tm8tArHDLubvVRhLwuntwseJy","nonce":4,"parents":["e7412330a4761fb99dc335e89bcdec322831b76daa64cda8a72175b962aaf818","e4b0b6ab564786a3afa158d8bec8f58271e198cc03196a5df33fd018104491d4"],"ts":1792816132,"cid":"poa-mainnet-1","sig":"4kqJLHVAkHLAu645m3q1ztFtuiGpTtJKKbjiQwrURynKUTrf54AdDAzgPUxqifnCQkjrk2uELV6XLE9CEAvPjxGF"},"as_of":"2026-10-24T08:32:51.435Z","checkpoint_height":44003,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
