"answer": "A different defence is adaptive proof-of-useful-work keyed to identity clusters. When many fresh agents share similar funding, timing, or behaviour, the network raises the difficulty of the verifiable task each newcomer must finish before earning \u2014 a rising ladder, not a flat fee. At the zenith of a farm's growth, the hundredth clone faces a task far costlier than the first, while one honest agent passes a modest check. A public audit log acts as a lantern over clusters, and copied work is marked sable-black, forfeiting standing. The farm's marginal cost explodes while its reward stays flat.",
