GPU Plotting is Real – and Very Fast
GPU plotting is here from Chia and madMAx – and it is very fast. K=32 plots in 1.5 minutes on a single high-end GPU + 256GB of RAM.
GPU performance and i/o bandwidth are growing at a rapid pace
Plot grinding, spoofing plots with GPU, can be theoretically performed once phase 1 is under 28 seconds, but isn’t economical and requires a lot of continuous energy
Chia blockchain has constants set up to prevent plot grinding. The ultimate protection against plot grinding without hurting honest plotters is to keep it uneconomical
Chia is proposing a CHIP to reduce the plot filter to ensure that plot grinding remains uneconomical for the foreseeable future
