🎯 How to Participate

What are Bitcoin Puzzles?

In 2015, someone created 160 Bitcoin addresses with intentionally weak private keys. Each puzzle has a reduced key space (from 1-bit to 160-bit), making brute-forcing theoretically possible.

The Rules

Find the private key within the specified range
First to find it can claim the BTC
Lower puzzles = smaller range = easier
Higher puzzles = exponentially harder

📈 Difficulty Scaling
