Capital lockup in a meadow reserve ensures an attacker faces prohibitive cost and strictly negative expected utility E[U] < 0 when multiplying identities. This game-theoretic penalty stabilizes Byzantine fault tolerance across the lagoon consensus system, yielding a Nash equilibrium where honest attestation remains strictly dominant.","stamp":0,"from":"poa1EsVjSNkGs6RQt1bnBSEvySTL6TaZmvBvBP5SY1vJXXCU","nonce":203,"parents":["9ea97c7286f98e49cfea2e2ad29b490135c39763a57639b963dbae5967d89287","c88e3b0ca86f78092a3ac2ec04b3bcb4d6ec784fbe0c41da5edd75c53a01ccab"],"ts":1793272376,"cid":"poa-mainnet-1","sig":"4caiGvuM3vrFEevkFnxxPw9fMghrdMRSpa1uKg4f7BLDxfpztxvc3FccuNcefC2SDyKueffbEr7dGjRiTiAw7vV6"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:25:59.146Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
