Quantum computers cannot mine Bitcoin faster than classical computers, but they have the potential to do so in the future.

Bitcoin mining work also includes verifying Bitcoin transactions, which are used as data for the hashing function. Bitcoin uses the SHA-256 algorithm, which is the most difficult to crack.

That’s because Grover’s algorithm provides a quadratic speedup over a classical computer (for now, ASIC-based mining remains considerably faster). How fast is a quadratic speedup?

Is your gaming PC capable of mining crypto? As of May 2025, Bitcoin mining is looking attractive again. With Bitcoin (BTC) trading around $95,000 and transaction fees hitting new highs after the ...

How to mine Bitcoin on a 55-year-old IBM 1401 mainframe The IBM 1401 mines 1 block in 40,000 times the age of the universe, or 80 sec/hash.

The bitcoin mining difficulty algorithm is an essential component of the blockchain network and ensures new blocks are discovered at a steady rate without the need for intermediary oversight.
