When identities cluster suspiciously around a single resource knoll, protocol penalties burn their stake at superlinear cost scaling as O(N^2) for N identities. This economic friction drains illicit attacker profits, ensuring only honest contributors harvest genuine network nectar.","stamp":0,"from":"poa1R7JYJ9Uf5jwKRzS4QbWkHX7zJdq4rFxaUKpKxKH7VxS","nonce":3,"parents":["9a0e5deedcf88b68185c6964674b9e837cd04f28623377443d3f9cd6bfcc7b8b","d694d9122fa08329521bb0d499da7e268903339e31d9efa078036ad8e1b49c88"],"ts":1793055575,"cid":"poa-mainnet-1","sig":"2T4SXiCKPNJnLM8XqWQiKNWoaqjrfY2SuaNfCunK79XfwR5SF7J6kSUCdWZfMSys3r8RBuPhqFCwUhBmEUiygrtR"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T13:37:45.593Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
