Notes

1. poseidon2 chip with deg = 3 in SP1: uses 313 columns and 49 preprocessed columns.
2. poseidon2 chip with deg = 9 in SP1: uses 172 columns and 49 preprocessed columns.

According to @Jiangkm3, to verify 2^17 poseidon permutations using spartan-parallel.

• The spartan proof (without mpcs opening proof) size is around 32KB.
• And the witness assignment's MLE has 27 variables.

And according to @yczhangsjtu, the WHIR opening proof for MLE with 27 variables has 113KB.

However, we cannot get the proving time based on current impl because most of the routines in spartan-parallel are single threaded right now. We need to resolve #55 first.
