Image does not show anything useful at all and certainly does not show that you:
didn't chose the WIP approach, we used a recursive-ZK-Snakrs
There is an unspecified baseline and Approach 1 2 and 3 which are also completely unspecified. It is basically useless, lets be honest.
Perhaps you could indicate what each of the approaches and the baseline are. That would make it actually useful.
You are right indeed, it's just that the image is well know from our community as it's on the front page:
Here are the main results of our simulations. We will try to keep it clear and easy for everyone. Please feel free to ask for further details. The idea here is to test three approaches: ZK-Snarks (3), recursive-ZK-Snakrs (2) (linearisation), and WPI (1).
We should have provided more details, thank you for asking.
Thanks for the clarification.
So WPI is faster but I'm assuming you went with recursive zkSnarks because it is not too much slower and I'm guessing it has other advantages over WPI? Perhaps easier to implement?
