Reason for abandonment #1

Did this project lose steam due to the rapid iteration of zk-SNARK schemes that convinced the development team that it is much wiser to iterate on CPU-based prototypes rather than park effort in a more complicated GPU implementation whose underlying scheme might become obsolete quickly?

Are there not some shared primitives to zk-SNARKs which one might reasonably believe would stand the test of time and hence may deserve to be accelerated on a GPU, so that future schemes could build atop of them?

Hey!

Partially it was due to the fact while rented GPU is faster in terms of time it happened to be as economically efficient (time * cost) as CPU prover. This fact along with a newer proof systems that need to be evaluated is a reason why GPU provers is not investigated on a scale. Nevertheless there is a "belle_cuda" repo with a complete Groth16 Cuda prover.

Hi, I see. In theory then, GPUs, especially if you own a fleet, could still provide massive speedups and cost savings? Asking with a view towards future developments.
