Detailed Description

template<typename BuilderType>
class bb::UltraRollupRecursiveFlavor_< BuilderType >::VerificationKey

The verification key is responsible for storing the commitments to the precomputed (non-witnessk) polynomials used by the verifier.

Note: Note the discrepancy with what sort of data is stored here vs in the proving key. We may want to resolve that, and split out separate PrecomputedPolynomials/Commitments data for clarity but also for portability of our circuits.
