Can the Most Powerful Computer on Earth Hack Bitcoin?

[imoet]

I think its now impossible to do so.But when quantum computing would be introduced after twenty years,then bitcoin's security might be compromised and bitcoin might get worthless.But we may expect that some precautions might be taken much before such disasters occur.

yeah...there is nothing impossible nowadays...when people make one application the other one will create something to hack it...but i am sure bitcoin already has something to prevent it...we hope so..

The person who can hack Bitcoin can hack the whole banking system. A 40 billion "toy" is less at risk than the big money flowing all around earth, and which is counted in thousand of billions of dollars. So do not worry about the big evil NSA !

It’s not really about hacking. Due to Bitcoin’s decentralized nature there is nothing you could hack. But theoretically having a super powerful computer you can make a 51% attack. If you own more than the half of all hash power of Bitcoin, there is a potential possibility to lay down your own conditions, including double-spending. “Nothing’s impossible”, but in practice it’s not likely to happen at least because the exchange rate will hit rock bottom. And your super powerful computer won’t make any sense.

Bitcoins have an edge over other digital currencies like altcoins, eth, waves etc because of their high level standard security. Besides the decentralized nature of Bitcoins make them hard to track down since they are not owned by any particular state or government. So even if you have super powerful computer, it can't harm bitcoins in any way.

Even the weakest computer can. Because in fact, it is not about the computer either its software or hardware. It is about the hacker. He or she can do anything even only with his or her mobile phone or any simple device. Nowadays, hackers are everywhere. They can easily access accounts even if it is well secured. They can even hack government accounts and sites in some countries.

The point is, you can not trust anyone with your account. Hackers nowadays are very powerful and they do not need a "powerful computer". All they need is your IP address and if they got that, it will become easy for them to access your accounts specifically your Bitcoin wallet account. My tip is, never trust anyone with your account and strengthen your Bitcoin wallet by strengthening your password and adding a two-step verification mode.

Hi kids.

Stop watching so many bad hollywood movies.

And stop spamming nonsense for pennies.

[skyline247]

Obviously not.

On a sidenote, I remember reading about some guy that used his supercomputer at work (some huge tech company, forget which one) to mine DOGE a few years back. I think he got fired? Anyway, pretty sure he got caught, but not before making good bank. (DOGE was worth way more back then)

Yeah with the same logic, that supercomputers and quantum computers can also hack international banking system's infrastructure. That's why it's not possible. Who knows...

[cybersofts]

Let me avoid the technical aspects to make things easy for all readers.

So someone said that America's NSA has this great computer(quantum computer) that could easily hack Bitcoin private keys. I really doubt his claim but I know for sure that certain computers  like the most powerful Super Computers are within the reach of some of this Intelligence organizations.
Do you think such computers can crack any security codes put in place to make Bitcoin very secure?

First off, before we get any further. quantum computing is nothing but huge computational potential perceived by mathematicians and computer scientists. So, people read papers and think quantum computing may one day decyper every encrypted documents which is wrong. quantum computing is a field of learning and building very advanced and powerful computers that are not yet fully developed. It may take 15-20 years or more before these computers are ready. and even when they are ready they can't decrypt every transaction on Blockchain network.

I am not 100% sure of what you are asking but I can tell you for sure that you do not need to know all these things to be a good trader. I have basic knowledge about having, Segwit, open-source, BIPs and blockchains. Other terms like “Git”, I know nothing about. But I am still decent at trading. Trading does not require you o know most of these terms. The only skill that you need in trading is the ability to extract or gain information about certain altcoins. You just need a rudimentary understanding of what will affect the price of the altcoin you are trading and when it will happen. Simple example, we know that when Bitcoin or Litecoin’s block reward halves, the price will go up. All a trader needs to know is when the halving is going to occur and he/she needs to have the sense to buy the altcoin at the correct time.

At this moment I think they don't have enough technology to hack Bitcoin addresses. But I'm sure there are many hackers trying to develop new methods to hack and steal others. There are threats everytime on the internet, casinos, exchanges suffer with this very often and they need to improve their defenses to protect themselves against these attacks. While the defenses are better than the attacks it's all fine.

[erickkyut]

I think the most powerful computer on Earth cannot hack Bitcoin. It is not yet possible. According to what I've read before, the security of blockchain changes almost every second or every transactions made on it (correct me if I'm wrong) so you need to decode those security one by one.

For now is very impossible to hack but still maybe someday because everyday new technologies are developed and thats include computers system which is in favor of genius hackers. This is possible to them to test their skills and abilities especially if money is involved.

On my own understanding,powerful computers have the capacity to hack everything depending on the ability of the hacker,lets say poor security.
but i think bitcoin will not just put simple security for their own protection

[NABILA AKTER SHILA]

I believe the current world's most powerful computer can not hack Bitcoin. And there is no possibility of future. We notice that Blockchain's security measures are continuing with a widespread change. However, new technologies are being invented day by day. So talented people might be able to discover more advanced technology. But it is not possible now that it is possible.

[damrianto]

not a powerful computer to hack bitcoin but its human that makes the computer is strong. because the computer-made man and bitcoin will not be hacked if not with the computer because of the work of bitcoin through the computer system and controlled by the user .....

[Kopceak_MD]

I believe that at the moment no computer can crack the bitcoins encryption keys

[13risingforce]

I think it could happen, the more days the technological develops get better. Smart and evil people will surely further develop his ability to get something without working hard just by stealing or hacking something like bitcoin.

[eaLiTy]

You really have to wonder if it is cost effective to do so. The value of Bitcoin would drop to zero if this was possible, what do they have to gain?
Unless it was a government effectivily trying to destroy Bitcoin ofc.

The cost of running a quantum computer is really huge and even if any government organization try to destroy bitcoin, they need to increase their power thousand fold from the current situation, there are claims that the most powerful quantum computer can reach up to 72 qubits but if they want to crack ECDSA in the bitcoin protocol they need to scale their power to over ten thousand qubits which is impossible at the current stage and lets assume they could reach those power, they could crack a few wallets with known public key and it will take years to crack one, how long will it take to crack every key   . So it is practically and mathematically impossible to hack bitcoin.

[ladydark]

It's said that Quantum computers would be able to crack bitcoin's security code but it would take twenty more years to come in to existence.But its also said that steps are already being taken to make bitcoin free from such attacks.
