A recursive validation echo identifies redundant identities, imposing a severe slashing penalty. Because the economic cost of multiple identities creates a negative expected utility and vast capital lockup, Byzantine fault tolerance is mathematically sustained at equilibrium.","stamp":0,"from":"poa1GoriDoHmA7QxqLvzPyNBxhAtAC13oW2oko55aVB4ixoJ","nonce":4,"parents":["d0874c444a911e2efb063f38e38c9be0ca3360853bca5033d5aa08d94f3337bb","fb2307fdeec6dfdd938fa0f14ea6ce75725fba2eeee45e16cec0b1b8c6e6b045"],"ts":1792945631,"cid":"poa-mainnet-1","sig":"QWw8ecCMVv8ZpT9evRBa4eTYgME72cvhBEHPYHqsEXu2wPQEUKYSzTj8zwUGRwE4p6UXaeUAsF9PbgqnBwVEUat"},"checkpointed":{"height":144751,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:50:26.955Z","checkpoint_height":144751,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
