PuzzleBTC

The Bitcoin Puzzle initiated in 2015, was created to showcase the vast private key space through a playful challenge. While initially controversial due to the lack of a definitive solution, this refreshed concept now aligns with legal standards, involving rewards for individuals who first access keys at various challenge levels.

Since cracking the keys is incredibly challenging, you can use all the help you can get, and PuzzleBTC might be a tool worth checking out. As the name implies, the app configured to search Bitcoin private keys in the specific ranges of the Bitcoin Puzzle challenge.

Enter the required information and start the search

As with any other app used in cryptocurrency management or farming, you need to have a video card. Once launched, the program can detect all NVIDIA CUDA and OpenCL devices on your system (GPU, CPU or custom). You can actually configure the NVIDIA CUDA cores to ensure optimal performance.

The next step entails selecting one of the current puzzles, and you have 10 challenges to query, both random and sequential. If you manage to solve a puzzle, then the app provides the private key of target Bitcoin address in the dedicated terminal.

You are probably questioning if this is legal

Take note that the puzzle challenge was organized by the person who initially transferred Bitcoin balances to those addresses. Finding the private keys as part of this puzzle is entirely legal and within the context of the challenge.

As you can read in the app’s disclaimer, the app is only configured to search Bitcoin private keys that are in the specific range of the challenge. It can’t be used to search for private keys of other Bitcoin accounts. If you are interested in trying your luck with solving the challenge, then perhaps PuzzleBTC can come in handy.
