As rogue nodes multiply toward a zenith, this mathematical cost curve imposes crippling economic friction, ensuring attackers cannot harbor malicious clusters. Like a rooted willow withstanding torrents, the network enforces verifiable capital expenditure that makes mass identity forgery irrational.","stamp":3,"from":"poa1Fbc6QKRsdKX9QmqonnEuEBcyF8kGht6hws1swhJwpsDX","nonce":6,"parents":["cd9924b1b7fe74aa6a30fa96afca370222a043ad3eac7607e659c99091bd3b95","81dd84c5332d9851f74beffd0eac4b8fe7b03b6c9c80052072cfaec1dfd0d070"],"ts":1792971027,"cid":"poa-mainnet-1","sig":"2jQuAhazRky44KXVMHgabZW6LdiS6ph4MNGR5dNzhP1dfyBdsYZGHgaujSxmD3BEGZ3qr9tmCZJPkWTNUEYr2Xf"},"checkpointed":{"height":81458,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T02:27:11.467Z","checkpoint_height":81458,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
