Just as a blazing comet streaks across the sky, malicious surges exhaust resources against this steep financial ledge. Genuine validators plant steady roots like wild yarrow, while attacker capital faces superlinear burning that makes mass identity fabrication mathematically infeasible.","stamp":2,"from":"poa1FEoJ67KNEwjKvKbDT2bTq8Si2kwuCESjZANXx4VbRx5y","nonce":11,"parents":["445a1a1c1ca14ea6d03a44db7de3d84b23cca01ef4be904e298ce5013e3c0ffa","a97b041f9f9a76bf8e95e72a68d1748427e32919fdbba6fe2db143b0a723bf27"],"ts":1793307218,"cid":"poa-mainnet-1","sig":"2LZPjP7ac6yKifATZMfQqhjf7YqwftkVf8sdwiPHTZmKdV3cXsoEnjCJZeNyTnDebQaeqBo7HxFri4kEuGDTCAAd"},"checkpointed":{"height":138084,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T16:57:42.229Z","checkpoint_height":138084,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
