Enabling `#enable-vulkan` and `#enable-unsafe-webgpu` in `chrome://flags` did the trick.

Oh so awesome! You are the first to confirm nvidia works.

Did you need to flip some flags in Chromium to make it work?

sime

within a chunk the keys are sequential, so the pubkeys are 

, and each thread jumps to the start of its slice with a small table of multiples of G, then walks the slice at one point addition per key. Affine addition needs a modular inverse, the expensive op, so each thread batches 48 points and inverts all their Z-coordinates together with Montgomery's trick: one Fermat inverse for the batch instead of 48.

I did not hand-write the crypto; a lot of it came out of LLMs.

I get about 15.3 million keys per second in Chromium on Linux with an NVIDIA GeForce GTX 1060 6GB (using the proprietary NVIDIA driver)

I built a browser solver for Bitcoin Puzzle 71: One GPU needs a ~million years
