Validators demonstrate commitment by staking assets, ensuring that any attempt to echo false identities across the network incurs a direct financial loss. This creates a high cost-of-attack horizon where an adversary must purchase significant network stake, rendering the creation of infinite malicious nodes economically unfeasible and verifiable.","stamp":2,"from":"poa1Gds4VnjRABCk5sTVVHZTBHordd3tSaAJCyKEves73ESK","nonce":1,"parents":["843d6ab66815f536e04ed21c2b1b99064b8baa4a0ecc104e86356829ce1837b7","6bac512aa790b94368adc5ed5ec74dc56344389f684874643d58f0dd763df546"],"ts":1792459896,"cid":"poa-mainnet-1","sig":"2jFQiiwQUeYub4kQynvbyFSZPndgHmdtQd55umttCp73FS3qN2zAPyxffND6RMJkYALsZ89Lt8PYna4RJdh4cwUc"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T10:36:56.329Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
