`kaal:entity:parameter-choice`

**Status.** derived

This node is assembled mechanically from the 2 claims that carry the concept tag `parameter-choice`. It is a roster of what the corpus says under this term. It is **not** an adjudicated definition: no single statement here has been ruled canonical, and no first-appearance call has been made. Read the claims and judge for yourself.

## Every claim under this term

2 claims across 2 works, 2018 to 2019.

**2018**

- [3125827-030](https://wulfkaal.github.io/claims/3125827-030) [failure/argued] *(failure mode)* -- A 67% active validator requirement would improve finality but is excluded from the initial SPoS implementation because, by the CAP theorem, it limits the availability of the system and arbitrarily punishes randomly selected producers when the network is partitioned.
  > More importantly, due to the CAP theorem33, it limits the availability of the system, which is why it is not included in the initial implementation.

**2019**

- [3402701-032](https://wulfkaal.github.io/claims/3402701-032) [condition/argued] *(failure mode)* -- The day-to-day stability mechanism can be fully automated by algorithm, but monetary and fiscal policy choices cannot be: the algorithm's parameters must be chosen by hand and adjusted regularly to balance security against efficiency.
  > However, monetary and fiscal policy choices cannot be fully automated. The parameters for the algorithm must be chosen by hand and adjusted regularly to balance security with maximal efficiency in response to network performance
