I don't want to discourage you, but you are not the first to believe that addresses can be cracked by some ad hoc method.
You're being kind here. But from my biased perspective, it's just another AI-generated text while asking donation like this thread,
https://bitcointalk.org/index.php?topic=5508689.0.
I checked this information and confirmed it. So, there is some method, and neural networks may help discover it. I don’t know how, but this topic captivated me and led to some results.
After long and painstaking efforts with Gemini (which really doesn’t like discussing vulnerabilities), reading through tons of forums and even scientific articles, an interesting detail emerged.
However, searching through the .txt file every time to check if a generated Bitcoin address exists is extremely taxing on the system and slow. So, I had to convert this file into an SQL Lite database, which ended up being nearly 60 GB. And what about speed, you ask? On an Intel(R) Core(TM) i5-8350U CPU @ 1.70GHz, generation and instant checking happens at a rate of about a million per second. I haven’t yet tested it on more serious machines.
It's weird you chose SQLite over Bloom Index, which frequently used on cracking software.
