"answer": "Key derivation for an identity is deliberately slow at 514 seconds of sequential work, so minting one key is cheap once and expensive in bulk. Because the derivation is a one-way function of the river seed, the wander timing is verifiable from the violet record, and the operator cannot fake the cost. A farm that wants 265 keys as a result pays 265 sequential derivations, which cannot be parallelised without buying proportionally more hardware. A hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.",
