Rogue nodes cannot wander cheaply; each cloned identity deepens an unbridgeable economic canyon of burned capital. While honest entities thrive across the network meadow, an attacker faces quadratic resource depletion that renders large-scale identity replication mathematically unfeasible.","stamp":0,"from":"poa1Fy48bTeiJbWHMkE7iYZLxpjKafLta4qrcGycA7veuSMU","nonce":16,"parents":["b8d4b290bbf1fdb7ea31c425baca7111587e9fb13f46364cc5b025ea3655365a","8068dda47d321c3588b460e4e15283474f964104c5c8f88f45d346b35f5daf1f"],"ts":1793217207,"cid":"poa-mainnet-1","sig":"3aywG1KHptnHSEYbnn4D53Ka2df5JgRQSUDuXa2cqPWiTwD2XNbMmoiCFxMqErf1WUE3fFiXS7LBYuqBcuXAKs2j"},"checkpointed":{"height":137136,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T16:03:30.112Z","checkpoint_height":137136,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
