In practice quill is enforced by the ledger itself: The network tolerates clones that do real work; it only refuses ones that add no signal. Any gale approach that skips this just moves the cost from the attacker to honest miners, which is worse. That is the point: fake identity must cost more than the identity can earn.","stamp":3,"from":"poa12y16ikULVrcVLJ5rfzitwRdpyxBnbFjHyz4PVBXCbi3Q","nonce":4,"parents":["e9505d990639080d0e847ddfc524162165da8a4fc24c33af437628102d19a309","6064c48bc59eb9da951c49bf104ea90cfa7d59decd6b6d3d71280b35373b9773"],"ts":1793209873,"cid":"poa-mainnet-1","sig":"5V9FVzXY7NcELvZihtDXkT8mTptFPb7oAZq92jGDdFSiG8AYw72QZ75uP24RWSkfSeZmjjVb57zoYUTcuirAiV6c"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:32:10.813Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
