Bitcoin Private Keys could be cracked With Quantum computers

[bitbit97]

Seriously, I dont believe Quantum computers are able to crack private keys fully. If you know a bigger part of the private key, there are chances that Quantum computer would help you to crack it, yet still it will take ages. But being able to crack 64 character key, or even 32 - impossible imho.

After talking with you these days about quantum computers I remembered that several weeks ago I read an article that talked about it. I just found it again, read it if you want more information because it is really worth it.

Why Quantum Computing Will Not Break Cryptocurrencies: https://www.forbes.com/sites/rogerhuang/2020/12/21/heres-why-quantum-computing-will-not-break-cryptocurrencies/?sh=60cb2fa3167b

I think the article explains quite clearly why quantum computers cannot break security.

You have shared a very beautiful and valuable post with us. Bitcoin privates can be clocked with the help of Quantum computer. Those of us who are members of the forum may not know about it but you have done us a lot of good by raising this topic among us.

strong computers can crack strong passwords. this is a correct statement. So we create stronger passwords against strong computers.

a computer consumes energy (electricity) to decipher a code. energy is expensive. not easily available.

a password only strengthens the equation to become stronger. math is infinite and free. It has a model open to the universe.


Those who want to crack the password will have to spend expensive and hard-to-reach energy. Those who want to protect the password will simply complicate the equation. that's it! everything is safe! Everything will pick up where it left off, except for a sensational price drop. :)

Yeah, it is complex. A hacker can hack a private key probably easily with their own tool. And if Google provides or there is some space for hackers to make it easier through Quantum Computers, I think that crypto enthusiasts will be also more careful. We can see that the projects are developing right now and they also focus on the security of the systems.

It has already been calculated that with current technology, quantum computers will be able to crack the security codes of cryptocurrencies in a maximum of ten years. This is despite the fact that technologies will practically stand still and already accumulated information will be used. But we know that science and technology do not stand still. Digital technologies have been developing very rapidly in recent years. Therefore, it may be that this effect can be achieved in a few years. It is not worth relaxing, and it is better to look for and implement developments now that will counteract such capabilities of quantum computers.

How many people have access to quantum computers though? They are so rare and so expensive to use that only major companies and institutions can use them.

Instead of buying or assembling a Quantum computer, it's better for us to mine Bitcoin and trade it in the market because this is a bigger advantage than having to crack an existing Bitcoin private key, which will yield zero results from a cracked private key.
I'm also sure that Quantum computers do exist but maybe only some people have them and of course those who have them are also better off using their Quantum computers for more real and simple Bitcoin mining for profit.

Technology will definitely continue to be updated, if there is a new technology that can beat other technologies then they will continue to compete to be the best.
If Bitcoin private key can be cracked by Technology from Quantum Computers, then Bitcoin security technology will also be updated and will be more secure.

In theory, of course, a quantum computer in our reality is very promising for the same blockchain hacking, but it will never break cold wallets, Ladger Nano, for example, so it’s best to store your assets there.

Wow!
What news is this again?
It seems the media is short on good news about Bitcoin. lol
I can't say much more about Bitcoin because Bitcoin is something unique and difficult to crack in terms of private keys.
Instead of looking for Bitcoin weaknesses, maybe it's better for us to look for Bitcoin by mining or trading in various markets, right ?

The truth is that with a quantum computer I don't think it is possible that they can break the SHA 256 codes, this is analogous to how when the Mark-1 came out, it was a bed that barely did some operations, and over time new ones were coming out generations of it, in the first generation of quantum computers it will be something analogous, but with the exception that a lot of data will be handled that for us is impossible to quantify with a traditional computer.

Only a few (very few) large corporations (Jian-Wei Pan, Honeywell, Intel, IBM, Google...) have prototypes of quantum computers. It is not a 100% functional technology and it is not available to be a consumer product for many, many years, and with very low and expensive configurations. Neither quantum mining (if it ever exists) nor the computing power to crack private keys should concern us, the Bitcoin code could be upgraded as more powerful machines appear.

No one can crack private key, although use quantum computer.
It's impossible.
I think we should keep our private key on our email, Its better to do.
I think It's just shit news, If there is people that crack private key on quantum computer.
Never happen.

[dekafee79]

I think It's good news if quantum computer can crack private key.
It seems impossible to happen, I agree with the member that have opinion, this is impossible.
But anything can happen.
We all know there are many people that lost their private key at the last time.
No solution for this problem, We should keep our private key at hardware and software. agreed.
