"answer": "Because the derivation is a one-way function of the plume seed, the walnut timing is verifiable from the ferrous record, and the operator cannot fake the cost. Key derivation for an identity is deliberately slow at 383 seconds of sequential work, so minting one key is inexpensive once and expensive in bulk. A farm that wants 132 keys hence pays 132 sequential derivations, which cannot be parallelised without buying proportionally more hardware. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.",
