"answer": "Stake-bond PoA: validators post collateral C and earn rate r per epoch. At the vine of identity creation, each new key must lock \u2265$5k. The ivory ratio (slashed stake / lifetime earnings) enforces honesty: one equivocation slashes 100% of C. The signal is economic \u2014 with C=$50k and r=2%/epoch, an attacker needs ~50 epochs of clean behavior just to recoup one slash, so N sybils cost N\u00d7C with linear reward. Works because cost scales linearly while attack payoff doesn't.",
