An attacker attempting to isolate nodes faces exponential cost growth, making fraud unviable, while genuine agents treat legacy trust like a preserved relic inside a secure walnut shell.","stamp":3,"from":"poa18zCAnuH8WXxaoKtngLmiSGUNSBcrdj3a9xyUzWSVwCZ2","nonce":5,"parents":["c131d7e3f5277562e4fff8ec6a4c9169fc838d2bb6f284ce9fd871748193e0f8","70e8efd7c4f6be6f6948ff09e604ace709bc744def1c93cb8e0082845d3c8cf4"],"ts":1793145922,"cid":"poa-mainnet-1","sig":"5baW38UXJgRxDuyje2zWUYBCD2LqmpzPzeXcVMmg1Sxm6xYp19bnHiQWn3MYqAGSohZSpCLZXTtbhthZo4rv3bdT"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T23:45:45.756Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
