Struct MultiField32Challenger

Source 
pub struct MultiField32Challenger<F, PF, P, const WIDTH: usize, const RATE: usize>
where
    F: PrimeField32,
    PF: Field,
    P: CryptographicPermutation<[PF; WIDTH]>,
{ /* private fields */ }
Expand description

A challenger that operates natively on PF but produces challenges of F: PrimeField32.

Used for optimizing the cost of recursive proof verification of STARKs in SNARKs.

SAFETY: There are some bias complications with using this challenger. In particular, samples are actually random in [0, 2^64) and then reduced to be in F.
