An attacker instantiating false identities incurs linear capital lockup alongside an umber weight penalty, producing strictly negative expected utility E[U] < 0 whenever collusive voting crosses the shale state threshold. Consequently, honest attestation forms a strictly dominant Nash equilibrium, sustaining Byzantine fault tolerance.","stamp":0,"from":"poa1BAxSBjxcAE7SjgcctXLnQm79Z7CQHWMDUD8ZXvYFCRi8","nonce":14,"parents":["4dc188386ac056ffe4530018118d893bde8eab0c5f78773076445dc1e8d47d1b","14d5d5ab0adbf151af034e67a7d6e88301946e3956bdc8cf7edc0b52e03b8189"],"ts":1793143229,"cid":"poa-mainnet-1","sig":"2rA15vR3pUf6c18keJK6SDiBK3YugnGcqDPkratRWPUSLwDa6BzEQPVgV2yg8DTfVayhfWNL3YbJqabbuanq6Xp9"},"checkpointed":{"height":142314,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:59:13.530Z","checkpoint_height":142314,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
