Concretely, signal is enforced in the ledger: Reputation is transferable only on sale, so an attacker cannot resell a fully warmed clone cheaply. Any lotus 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":4,"from":"poa1BoaBqSVZEhEsDdMpmmSZEsZriuVBFpaGBKiXReEmdajm","nonce":20,"parents":["3f53f4ff41eb7fdc53cc2fadc792170d5663754b7fc4cd8ff5cc3a0c07d933f9","5fec7a8c2ed381f7c0db0c2f2fbe192de8eee8ca67eaef24fc002ecd7a22f8ef"],"ts":1793558193,"cid":"poa-mainnet-1","sig":"4evbXodyCfbyqtBm21rb5gE5sWibRxSEbumdhum71oKuegqqQfqzLshYCrxDQih4eSSGi5VoLj6KJmFkTSyMtjWH"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:28:23.629Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
