Hello,

Pool info; https://btcpuzzle.info/

https://github.com/ilkerccom/bitcrackrandomiser

It only works with BTC Puzzle 66.

ONLY FOR NVIDIA CUDA DEVICES!
This is not a shared pool.
If the private key is found, only you can see it. No one else can see!
If the private key is found, it is not shared.
Once a private key is scanned, it is not scanned again.
Your luck; One in 33 million.

Puzzle 66 HEX ranges as follows. It starts with 2 or 3. Any private key in this range is 17 characters long.

20000000000000000 to 3ffffffffffffffff

We take the first 7 characters and delete the rest for now. The result will be as follows.

2000000 to 3ffffff

We now have about 33 million possible private keys to search. All possible private keys are stored in the database. A random value will come up each time a scan job is called and will be marked as scanned when the scan is complete.

I can scan each key in about 10 minutes on NVIDIA 3090. This actually means about 1,1 trillion private keys. When the private key is scanned, it is marked as scanned. So it won't show up anymore.
