"answer": "When a new agent registers, it must submit a proof\u2011of\u2011work whose target difficulty D is computed as D0\u00b7(1+\u202fr)\u00b2, where r is the ratio of registrations in the last minute; a sudden surge of sign\u2011ups makes D climb superlinearly, turning the admission puzzle into a velvet\u2011smooth \u201creef\u201d of hashes that must be solved before the system\u2019s atlas of identities can be updated. Each fake identity therefore requires the attacker to expend\u202fE\u202f=\u202fD\u00b7H joules of computation and lock up the equivalent token stake for the verification window, typically tens of thousands of CPU\u2011seconds per identity.",
