  1. Change multiplication proof: the algorithm in Doubly-efficient zkSNARKs without trusted setup Figure 5 is more efficient.
  2. For the realization of point addition proof in this repo, P!=Q constraint should be added.

A clean version with respect to the pull request #4

Almost there: I think the next round should solve it, once I understand the paper and we make the code match.

k_y = rnd(params.c.order),
k_z = rnd(params.c.order),
kx = params.c.newScalar(k_x),
ky = params.c.newScalar(k_y),

To make my life I easy I would appreciate completely changing the notation to match that of the paper. It's very difficult to determine which variables are supposed to mean which without doing that.

A4_1 = params.commit(k_z),
A4_2 = Cy.p.mul(kx),
A4_2 = (Cx.p.mul(ky)).add(params.h.mul(kz)),
// Step 2: Compute challenge H(Cx, Cy, Cz, C4, Ax, Ay, Az, A4_1, A4_2)
