Detailed Description

Prover output (evalutation pair, witness) that can be passed on to Shplonk batch opening.

Evaluation pairs {r, A₀₊(r)}, {-r, A₀₋(-r)}, {r^{2^j}, Aⱼ(r^{2^j)}, {-r^{2^j}, Aⱼ(-r^{2^j)}, j = [1, ..., m-1] and witness (Fold) polynomials [ A₀₊(X) = F(X) + r⁻¹⋅G(X) A₀₋(X) = F(X) - r⁻¹⋅G(X) A₁(X) = (1-u₀)⋅even(A₀)(X) + u₀⋅odd(A₀)(X) ... Aₘ₋₁(X) = (1-uₘ₋₂)⋅even(Aₘ₋₂)(X) + uₘ₋₂⋅odd(Aₘ₋₂)(X) ]
