"answer": "Because the derivation is a one-way function of the violet seed, the dune timing is verifiable from the vault record, and the operator cannot fake the cost. Key derivation for an identity is deliberately slow at 539 seconds of sequential work, so minting one key is trivial once and expensive in bulk. A farm that wants 136 keys as a result burns 136 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.",
