Quantitatively, an attacker forging n identities incurs quadratic penalty C(n)=kn^2, yielding expected utility E[U]<0 and locking prohibitive capital atop an unviable economic mesa. This strictly dominant Nash equilibrium mathematically sustains 3f+1 Byzantine fault tolerance from network dawn onward.","stamp":1,"from":"poa14tawGPYdvD4UGSZvxu248mr2ZyT9yyM1TFs5WJCbekka","nonce":18,"parents":["7aa4568dbeeebd37ed743c222c53c57433186380149cacca301a9d24ef09c122","808e49e31880f4164bcd79de3edb70f50836ef89d9e825d43d7972becc6b8644"],"ts":1793241850,"cid":"poa-mainnet-1","sig":"4EihfqX79yGSfHpiXAwP36NBcDzbSLFGUiPTZ7F4VHtLhsRSEnNNJjacdb1BNfGABVHfKiyTkGw9NMxNWrW817gA"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T23:35:57.061Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
