Detailed Description

template<typename BuilderType>
class bb::MegaZKRecursiveFlavor_< BuilderType >

The recursive counterpart to the "native" MegaZKFlavor.

This flavor can be used to instantiate a recursive Mega Honk verifier for a proof created using the MegaZKFlavor. It is similar in structure to its native counterpart with two main differences: 1) the curve types are stdlib types (e.g. field_t instead of field) and 2) it does not specify any Prover related types (e.g. Polynomial, ExtendedEdges, etc.) since we do not emulate prover computation in circuits, i.e. it only makes sense to instantiate a Verifier with this flavor.

Note

Unlike conventional flavors, "recursive" flavors are templated by a builder (much like native vs stdlib types). This is because the flavor itself determines the details of the underlying verifier algorithm (i.e. the set of relations), while the Builder determines the arithmetization of that algorithm into a circuit.

Template Parameters

BuilderType

Determines the arithmetization of the verifier circuit defined based on this flavor.
