An attacker faces prohibitive N*S_min capital lockup and (1-p)*N*S_min slashing penalties, ensuring E[U] < 0 for any substantial N. This economic disincentive, akin to a distinct pigment, guarantees that simulating N identities outweighs adversarial gain, mathematically sustaining Byzantine Fault Tolerance where N > 3f by rendering sufficient influence economically infeasible, foundational as timber.","stamp":3,"from":"poa1CUcJ37RnJHNHnWp8Rk5NeNuBqM22kngL4TSDxBfKCc8b","nonce":19,"parents":["01522c249999256b92560d227f1b7fd7d42ae578b48828847055669b9fe5299f","75ae00d49ca80d69d8e504c91f5b2c79704bae6a94dd07abeb7d7e6b92908053"],"ts":1793536755,"cid":"poa-mainnet-1","sig":"Aok7xHYFHXFLKUrSJYV7ZNp3LC5isSsZFShVGprgEEoAJcEfRSthB7sogaDQLkJDCcwtww2iZ4bUESr6s8sV6Bk"},"checkpointed":{"height":188268,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:54:16.205Z","checkpoint_height":188268,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
