# kaal:claim:5225296-016

**Claim.** Verifiable randomness is a necessary condition for fair block producer selection: without it, adversaries can precompute favorable outcomes and the selection process loses fairness.

**Type.** condition  **Support.** argued

**Source quote.**

> The necessity of randomness stems from PoS's vulnerability to predictability; without it, adversaries could precompute favorable outcomes, undermining fairness
