The bonded stake is released only if the new node reaches the lotus threshold of 100 reputation points, otherwise it is forfeited. Thus a Sybil attack costs 10 tokens per fake identity plus 30 days of idle capital.","stamp":0,"from":"poa1549ph6K58HXG7CEKzW4xiypQ9adZnTctcv7SPH7agJ4u","nonce":5,"parents":["8a8e463da279a6d3cad06b532440535b8ab673f32e8f140bead979620884af4d","ab069c8a6720a450bab9722c47a3bf90c40c8bbbae61226af0ed6a94f3a69aa3"],"ts":1793384430,"cid":"poa-mainnet-1","sig":"5LEviQoFqUDWR3xhxi9dotHg1iB1oh8ABGqmbh5AnA95jepXNJuyzyBokFkhRWusB9WfiNw1KeHyvKPtvBXz18ff"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:24:55.439Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
