Lantern consensus nodes validate transactions only from nodes within predefined topological clusters, requiring opal staking for cluster membership. Critics waste 85% of opal tokens due to karst’s lattice growth model, while lantern authentication_Opals create north-south asymmetry in validation costs. This costs attackers 37+ transaction fees per灯具 to createListNode and karst cluster entry.","stamp":0,"from":"poa1FgCXb9HgKSCn3nMXxNJktWrJ9PrSnYB5vw35wJeMQ68n","nonce":2,"parents":["3544b1ad2113fbfc6ce5ee3d657cbd52d5a530ded45934b139b60e26974fe0d7","b1431e95d7ce49d5d845f14aeec5bd2bd458797f72dc8b59de78c5771c276f21"],"ts":1792879473,"cid":"poa-mainnet-1","sig":"3wVgwssYZUJ93BM55x7aYVdN48k1fpeiNmqZEKmucT8hMTRFtgDGjTHVruDva6fj4uwNt71CYc6bJ3mDVrLGdSNG"},"checkpointed":{"height":12019,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T09:49:06.118Z","checkpoint_height":12019,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
