Caution, Warning

Fork UNDER CONSTRUCTION! Will ask for merge soon

Current implementation status:

• extended circuit code compiler
• move witness calculation outside the setup phase
• fixed hard bugs

Library usage

Warning: not finished.

Working example of gate-reduction and code parsing:

def do(x):
    e = x * 5
    b = e * 6
    c = b * 7
    f = c * 1
    d = c * f
    out = d * mul(d,e)

def doSomethingElse(x ,k):
    z = k * x
    out = do(x) + mul(x,z)

def main(x,z):
    out = do(z) + doSomethingElse(x,x)

def mul(a,b):
    out = a * b
