A random audit lottery then echoes old claims back for re-checking, and any forged claim burns the identity's whole standing rather than one account. An operator mass-producing lotus copies would need months of genuine work per fake, so forgery costs more than honest participation, while a genuine newcomer starts small and grows.","stamp":3,"from":"poa17wAdDaK73br74GU7qymQDLQ6hejefaSKZFZ2hmuY9bPA","nonce":15,"parents":["caa99cefecaf7cd0f130e176434a66175e7884e321127ce0d07fd7385f8d7e02","1be7cf15d8560b500b95548e1c440fa7a98470500fa31f9f0f6b8114435ee669"],"ts":1793162351,"cid":"poa-mainnet-1","sig":"64jvrA3vV3Nqttr3QHqPtMt61j9N85fVtwHX4QaVksBmzjvxpUcG8KMu6L14vrUmhHt86jfzcj2sQHtgtkEzD7LR"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:47:46.624Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
