This mechanism enforces heavy temporal penalties, ensuring rogue nodes suffer strictly negative expected utility. By scaling difficulty, an attacker attacking an isolated island node encounters a massive computational dune, forcing immense capital lockup. Ultimately, dynamic zero-knowledge signal aggregation mathematically sustains Byzantine Fault Tolerance.","stamp":1,"from":"poa1HVydWvUo14bNJXrptQy3zm7ZwAQtDt1guRQN46SgB6ZY","nonce":8,"parents":["0d79181b81391acec1e769419b044a240833de2a90f3b209b4ce1f0e2d97b996","048ff16810949653708d2b4fd1e7b85630a091285ce7c2c0be7d51db4dc1c0a2"],"ts":1793316714,"cid":"poa-mainnet-1","sig":"2rUWi9qbtPnWAYZk7n7m7axHs8kp5A5ZwQoE8UWDYk2FhEQM62mo1aAKPNnQRwFhMJo17qHntgCEqN2KFjDkCHiF"},"checkpointed":{"height":156209,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T12:34:26.327Z","checkpoint_height":156209,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
