Yeah, seems like it could be a cool project/spiritual cousin however, I am not sure I trust the math/numbers that his program is showing lol

Code:
GPU          : GPU #0 NVIDIA GeForce RTX 3070 (46x128 cores) Grid(256x256)
  Base Key     : Randomly changes 65536 start Private keys every 1,000,000,000 on the counter
  ROTOR Random : Min 42 (bit) 20000000000
  ROTOR Random : Max 42 (bit) 3FFFFFFFFFF

  [00:01:39] [R: 392] [3D70309E4B8] [F: 0] [GPU: 573.08 Mk/s] [T: 4,623,532,294,144]

Let me know when you see it lol.

ha - great eye - yeah, the total completed and hashrate do not jive with the time completed.

it will be 2023 in a few days and progress bars, time remaining and items complete (simple division) remain of the bane of meaningful UI feedback.  Funny, though the version I built didn't seem to have a fairytale hash rate but it also didn't have what I was looking for in terms of gpu-accelerated random-private key production. The key assembly is still CPU bound from vectors of gpu-built device_vector of 16 or 32 bit-length unsigned ints.  Mildy sympathetic.. I haven't figured out a pure GPU method of initial key production, either.

this thread makes me want to drink heavily and hurts my head because of this pattern:

[rando new person]: I did it! I figured it out! <Insert not-plausible solution here>

[person with established account and actual contributions towards the puzzle]: dude, that's not how math works.

At any rate, congrats to whomever solved 64 this fall.   
I was looking for roto-cuda and found a couple repos with forks of it: https://github.com/search?q=rotor-cuda

I know linking to how to search github is essentially a lmgtfy move but some of youz guyz seemed to need that level of help.

Also ran into this, which looks to be at least a spiritual cousin if not a direct descendant to roto-cuda: https://github.com/graffitilogic/KeyScanner

This person's code looks to be informal with plenty of commented out paths of experimentation but I appreciated that it actually compiled for me in visual studio with minimum effort.
The random number generator was... novel? but the majority of the rest looks to be forked riffs on VanitySearch and BitCrack in the older commits.

anywho happy hunting you crazy kids.

64 puzzle found by this command, and modify rotar cuda from 2b to 6m keys search at cpu level (13-6100) uses gpu inside cpu where speed is 6m keys/s
./Rotor -t 4 -m address --coin BTC -r 2 -o newout.txt --range 8000000000000000:ffffffffffffffff 16jY7qLJnxb7CHZyqBP8qca9d51gAjyXQN

Wait, what?: Are you actually implying that someone using Rotor in CPU mode is who found block64.. in CPU mode? 
That seems impossible unless there is more to the story; an entire NOCs worth of CPUs or custom ASICs or you had your CPU blessed by a 2,000 year old wizard.

Rotor-Cuda is a cool take on Random-Assisted searches that has often been asked for but I just don't see how CPU-mode hashrates would get you there. 
Run (don't walk) and buy all of the lottery tickets you can afford, if so; because brother - luck is on your side.
