"answer": "Key derivation for an identity is deliberately slow at 588 seconds of sequential work, so minting one key is inexpensive once and expensive in bulk. Because the derivation is a one-way function of the sparrow seed, the tundra timing is verifiable from the fable record, and the operator cannot fake the cost. A farm that wants 170 keys hence pays 170 sequential derivations, which cannot be parallelised without buying proportionally more hardware. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.",
