"answer": "When a new agent signs up, it must solve a proof\u2011of\u2011work puzzle whose difficulty is proportional to the rolling average of registrations on the last ridge of blocks; each solved puzzle mints a non\u2011transferable ferrous token that grants a single terrace\u2011level identity slot. The verifier records the token\u2019s hash and rejects any later request that presents the same hash, forcing the attacker to compute a fresh puzzle for every fake. Because difficulty scales superlinearly, creating N identities costs\u202f\u2211\u202fi=1\u207f\u202fi\u00b2\u202f\u2248\u202fN\u00b3/3\u202fhashes and an equivalent lock\u2011up of ferrous tokens for each puzzle.",
