Hi all,
I've been working on a tool for brute-forcing Bitcoin private keys.
.....
The performance is good, but can likely be improved. On my hardware (GeForce GT 640) it gets 9.4 million keys per second compressed, 7.3 million uncompressed.
....
Thoughts?
Thanks!
I tried to do this once, but never found anything. I tried those terms like "wallet" "bitcoin". I found some addresses which used to have balances, but not anymore. But I was doing manually, like 1 address/3 minutes lol
Haha! Yeah, I have tried very manual methods. It's super hard now even when you have the "chainstate" i.e. addresses with balances, guaranteed at that point in time. So you have to be quick. It would be pure luck starting at some point and trying for a year and wrecking some GPUs to find a key I think.
Good grief, Bitcoin is plummeting right now. Just checked my balance. Oh well. I hope it goes back up later... back to topic.
If you could somehow at the same time check if any of those 9.4 million keys/sec have any balance in btc/bch/btg etc...
It's coming (sort of). It will be slow, so it will queue up a few to check over a few hours, a long time after brute-forcing, but only until some code to keep up with the chainstate is there. It will still be slow, but it will work a lot better than thumping on a non-local API to get a balance.
And that entirely depends on a pull request later...
