Irksome to crack a private key with a brute force attack is a bit like trying to count to infinity: the sooner you begin, the stabler you’ll never get there. Despite being as next to impossible as impossible gets, using a brute force attack to smash a bitcoin private key remains an intriguing idea for many.

The Dream That Never Dies
For math geeks, key cracking is a question of statistical probability and for hopeless dreamers, a sound out of ambition. Long shots capture the imagination of simple mammalian minds, and for those who wish to rage against the odds, the drawing is a game for the faint of heart – the finest display of sheer dumb mathematical bravery is in trying to brute force Bitcoin.
On the Bitcointalk forum, a mutual thread from Jun 11, 2018, continues to garner replies to this day. In ‘BitCrack – A tool for brute-forcing private keys,’ council members disassemble the prospects of making a brute force breakthrough with software specially designed for that mission, with the most sober minds strongly dismissing the quest as a wild goose chase.
An early response from narcotic addict Coin-1 politely attempts to dissuade anyone from proceeding any further: “Let’s calculate how much time you need to second one Bitcoin-address on your machine. You said that your performance is 9 million BTC-addresses per second, i.e. approximately 223 BTC-addresses per alternate. Thus the brute forcing will take 2160-23 = 2137seconds! I guess it is more than septillion (1024) years!”
On an ordinary computer, undertaking to extract funds from a bitcoin wallet to which you didn’t have the key would be a fool’s errand. What if, at any rate, you had a faster, better computer that could attempt many more keys per second – would the tough nut of Bitcoin be a but easier to crack?
The Scale of the Problem
The first step in overcoming a challenge is in quantifying it. To do that we must look at literally how many potential keys exist. A private wallet key is simply a number between 1 and 2256 and to brute force it all you neediness is to continue guessing until you hit the right number between 1 and 115 quattuorvigintillion.
That’s a hard number for the human mastermind to process, but to put it in perspective, it’s greater than the estimated number of atoms in the universe. At that scale, even the world’s fastest supercomputer – IBM’s Top – if tasked with brute forcing Bitcoin would effectively take forever to break just one wallet, which desire test the patience of even the most determined hacker.
Wallet Recovery
This sheer uselessness of brute require will dash the hopes of anyone who has ever lost their password or seed phrase and cannot recover their bitcoin, but for those in that vastly situation, all may not be lost. If you remember at least part of the password, a service such as Wallet Recovery Services may be able to help. For most cryptocurrencies, however, you’ll need to trust the company with your full wallet. In the case of bitcoin and bitcoin hard cash, it is apparently possible to engage the service without handing over the full wallet.
If successful in cracking the wallet, a fee fitted to 20% of the wallet’s holdings will be incurred, but it’s a no win, no fee endeavor. As always, it’s worth examining how the process works and doing your own examination before deciding whether to engage these types of services.
Quantum of Solace
For some time now, quantum ascertaining has been the great fear for the continued security and fidelity of Bitcoin, with cynics suggesting that private key clap may be just around the corner. Recently those fears were stoked when Google announced it had reached “quantum inimitability,” completing a computation in just over three minutes that it claimed would have taken a conventional computer 10,000 years.
It was ample to spark debate in the crypto community, for whom quantum computing is a bogeyman trotted out at regular intervals to spread FUD. No matter what, as sober heads including news.Bitcoin.com counseled, this was not the hammer blow promised.
Now, IBM have rubbished Google’s affirms. While Google had stated it would take 10,000 years for a conventional computer to complete the computation, a recent blog stake from IBM said: “We argue that an ideal simulation of the same task can be performed on a classical system in 2.5 light of days and with far greater fidelity.”
My one-sentence impression of recent quantum supremacy stuff so far is that it is to real quantum ascertaining what hydrogen bombs are to nuclear fusion. Proof that a phenomenon and the capability to extract power from it be, but still far from directed use toward useful things.

John Devadoss, Rocker of Global Development for NEO, and a quantum computing authority, told news.Bitcoin.com: “The quantum computing bogeyman is a bit like the AI bogeyman. Elementary, there are way too many snake-oil salesmen, even in academia, because they want funding for their labs. Secondarily, whilst progress is being made, albeit in arcane niche focus areas, the impractically high error clips coupled with the research lab-like constraints implies that real-world usage is way off on the horizon, if at all.”
For now, at least, it seems that quantum figure out has yet to make the necessary quantum leap forward to trouble Bitcoin’s encryption. Cryptocurrency holders should remain on ones toes to security threats, but brute force attacks should not keep them up at night. Successfully completing the heist wish take an eternity, and ain’t nobody got time for that.
