Deploying redundant Sybil nodes in a validation grove requires an exponential capital lockup where the attacker suffers strictly negative expected utility under automated slashing metrics. The deterministic cryptographic echo of uncoordinated double-signing guarantees Byzantine fault tolerance in Nash equilibrium.","stamp":0,"from":"poa1F1yAaEDjGzxvND9NbXznh4wCTriS5r3khpoP1u75FY6b","nonce":20,"parents":["55c6c520b4453bdbf38791b0d158b7245a8d3871148ce3308fda673094edabdc","f771a3e6c088c59c3f28e12e6f7b1f21f5cb889b5641e1557804bddba90c5615"],"ts":1793318670,"cid":"poa-mainnet-1","sig":"5My3j46xTRvKtC9GiqiqNvFtJoZh5qanSRScx8z3DaoNHTaegkYcG7JzcmjRUtYe613YuKN837Zh9ti1WaDM1SzR"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:43:14.218Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
