`kaal:entity:block-validation`

**Status.** derived

This node is assembled mechanically from the 2 claims that carry the concept tag `block-validation`. 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 2018.

**2018**

- [3125822-033](https://wulfkaal.github.io/claims/3125822-033) [mechanism/argued] -- In the proof of stake application, a block is accepted by the network only if it carries proof of success in a betting pool, and that stamp constitutes the entire cryptographic security of the chain at far lower energy cost than proof of work mining.
  > Blocks will only be accepted by the network if they have proof of success in a betting pool. This stamp is the entire cryptographic security, which costs far less energy to achieve than proof-of- work token mining.

- [3125827-025](https://wulfkaal.github.io/claims/3125827-025) [condition/argued] -- In SPoS, validators download the most recently upvoted validation algorithm and faithfully running it unedited automatically produces the winning vote, so honest validators are rewarded; this holds on the assumption that users controlling 51% of sem token power act honestly.
  > Faithfully running this algorithm on the block will automatically choose the correct vote to win the validation pool, rewarding honest validators, assuming users with 51% of sem token power act honestly. Honesty is defined as faithfully running the algorithm, unedited.
