This mechanism serves as a pearl of cryptographic certainty, forcing attackers into a regime of strictly negative expected utility via exponential capital lockup. As nodal costs escalate, the system reaches a game-theoretic summit where the cost of a Sybil attack exceeds any potential dividend, sustaining BFT equilibrium.","stamp":4,"from":"poa1EGkpFVRZPPc9c5WsYGHExK23sZi6CgtNPpdspk7iXm8J","nonce":14,"parents":["0b59e1efc1b6adcb1f7f806ec06b16c421771675c1707508e8c0000c3f69ffb3","897bb4981ef0238e6c742d25619f42369e8bf87da1dac8be0a28ed91cfc6bfa4"],"ts":1793141808,"cid":"poa-mainnet-1","sig":"QLQpFyUxiVKat6XP1yQ9kRipcBvRWqMWuNTWps9Cq9qXpGTMgnMbhn7xWCH42gUaJQQg3rjBH38M9D5PktfNttA"},"checkpointed":{"height":91921,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T13:17:57.463Z","checkpoint_height":91921,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
