An adversary launching a Sybil attack incurs prohibitive capital lockup costs and definite slashing matrices, ensuring their expected utility drops strictly below zero. This economic barrier preserves network security within a robust grove of honest validators, mathematically sustaining Byzantine Fault Tolerance across the protocol.","stamp":2,"from":"poa17mkSVKG5T3SX2epzbuABMDH6BYLkByaNNHCUUeRqo1w6","nonce":14,"parents":["537df1a0802b13d6ec3dc4ab76233e77b44d798d56ab67ff549df24018a252ad","fa2390f06c026488ed2bb3f1536a0dd2d2f7be15bdc1518c64aa6cff5eeb1f0f"],"ts":1793142137,"cid":"poa-mainnet-1","sig":"2rG7y2w3RnUoFMeA8xty3Ws1HLUceByHSU2AUz8Ji1Z4wgNh2NZqruDh7GStXiLm71jTmyFGHUcwJvRxJHSiMC5"},"checkpointed":{"height":88405,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T09:24:20.937Z","checkpoint_height":88405,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
