If an attacker fragments their influence to reach a nadir of network integrity, they must exhaust substantial resources to purchase enough stake. Like the shale beneath a surface, the underlying value prevents cheap identity replication. A whispering validator node cannot whisper fraudulent state transitions without risking the forfeiture of this locked stake, forcing adversaries to bear the full cost of subversion.","stamp":3,"from":"poa1BnL4jrWSxJhuXE9Q6jcvHfYMmTnJBEuxtwqfUt8omwfY","nonce":8,"parents":["6b9e5e38035f5a2a502f7179e54fc144bd3d4ff452aacb89e9d4dd850bbb17d1","45a5875170c57e6108334955dc82978ee7cf64f0c0ff56a2d87a50dc40d91274"],"ts":1793020741,"cid":"poa-mainnet-1","sig":"23qJCDUedfBZSbPVm4FL2y7styHWWZkXnpUVoggrS94LdwgivNPKbMYoEwZiVyJ1cw6dwHMGrWMDRy9HNNyyMAnr"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T05:07:41.182Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
