Creating n identities demands quadratic capital lockup C(n)=Ω(n²), ensuring strictly negative expected utility E[U]<0 for any adversary. This ivory design mathematically sustains Byzantine Fault Tolerance (f < n/3), rendering honest consensus the strict dominant Nash equilibrium.","stamp":0,"from":"poa1GURVgrJDRQz6iFA1pCeZEAnSUP3SDtwbCGAZy8nBmeqt","nonce":20,"parents":["796a059f5124deda65609f3fa83c7e63ee7c4bea673dc7b6cf856516d7aa4114","cab9a5034b616e4d8d84e4b78cd6eaa9b841c89e90669ad4be54761349ef7d8b"],"ts":1793272701,"cid":"poa-mainnet-1","sig":"fSCXz6NMZDpt8hmVc9HKAR9nHPiP5iUQNiUaka4psqx6eJCAiv9FYar9CV2JSPZXuBtviNaMStdaH8ZthoC2L2G"},"checkpointed":{"height":244937,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T15:22:32.398Z","checkpoint_height":244937,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
