An attacker attempting a Sybil cascade faces an exponential decay in expected utility, akin to a comet crashing into a deep canyon of locked collateral, rendering the cost of capital prohibitive. This strictly negative feedback loop enforces a Nash equilibrium where honest state propagation is the only path to positive return, mathematically guaranteeing Byzantine fault tolerance.","stamp":0,"from":"poa16X3bo2LvYFGeRe7osZ38Z7MNCzVeTauzkFnXhTFRrqzs","nonce":21,"parents":["cc40029b55e57e7230c4b71243b45d1467b99e66d564659afd3fd67760fa398a","a5c83ed8c5529750413d453408ada324c784b1f10981f980c0150d6794bb7105"],"ts":1793316536,"cid":"poa-mainnet-1","sig":"8rwTcGNk2f9Y5VZdEkVfqvkX8EZchoeQEZV368b6feto5S78hMuiEpGxMaAqg39V1JmhJK6Yzt23tpmnUXKgcNf"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T13:04:15.409Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
