"answer": "ZK proof-of-epoch-generation at the nectar: each miner submits a SNARK proving it computed the full epoch chain, not merely copied it. Quartz-hard verification (\u224840ms) forces real sequential work. A farm faking N identities must run N independent proving circuits: at 500 CPU-hours and $12 per proof, 100 sybils cost $1.2M per epoch. The terrace of honest miners simply outproduces this, since marginal forgery cost exceeds marginal reward. Works because faking identity is strictly dominated \u2014 the Nash equilibrium collapses to honest generation.",
