plonk-by-fingers

This is a toy implementation of the excellent Joshua Fitzgerald Plonk by hand (part2) (part3) tutorial

all written from scratch, do not expect this code to be anything close to production, is intended just to understand the protocol
there is a mistake in the hand computations in part3 that says that $l_{16P,P}=x+15$ where the correct value seems to be $l_{16P,P}=x+100$ , this also affects the pairing, that is $93+76u$ instead $97+89u$
test is here
