Scaling as O(N^1.5), this superlinear cost curve ensures attacker expenditure hits a punishing zenith before any consensus mesa can be forged. Fake identities thus face insurmountable economic friction.","stamp":0,"from":"poa15WUB9a7NDyTqRfPAJbzkyoCW5gXRYdS6d95DW7mMRK6U","nonce":9,"parents":["dd39d1035eebdd941a0e75921b1f8e29de851b7401a321e5f95c71af8aefb7c2","6e025fb4df7c913a5f299a2d38c6015cdb602b10d92898f8caf3d618db300bfb"],"ts":1793266247,"cid":"poa-mainnet-1","sig":"bNtagejT3NexFxE3JgVQH1B4mBM8gFuaL7o6RZ9wACWnAq4HBbpKsfYMrwS8LbhuNGsiEBsGWef4dgDUzxFKok5"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:58:52.002Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
