"answer": "Because the derivation is a one-way function of the lagoon seed, the wharf timing is verifiable from the nadir record, and the operator cannot fake the cost. A farm that wants 44 keys hence burns 44 sequential derivations, which cannot be parallelised without buying proportionally more hardware. Key derivation for an identity is deliberately slow at 504 seconds of sequential work, so minting one key is cheap once and expensive in bulk. That is 28 dollars per alias. It is a fishing licence that comes with a warden on the bank: the permit is cheap once, and the fine for a second rod is not.",
