Is Google supercomputer a threat?

Unless we have magic, cracking SHA-256 is almost impossible. Sure, you could crack it first try, but that's like rolling 99.99 on a dice game. 1000000 times in a row.

The supercomputer would guess much faster, yes, but it will still take eons on average for it to crack a private key.

Mining/hashing? Nah. It may be a little faster than an ASIC, but it probably costs hundreds times more than an ASIC.

Private keys don't use SHA-256. It will be significantly faster to crack a private key since there are known algorithms that QCs can do faster that do prime number factorization, an important aspect in ECC which is used to create the private and public keys. Quantum computers would have an advantage over classical computers in getting private keys from public keys, but it will still take a while. But the time it takes is much much less than the time it takes for a classical computer.

its not about the power its about the energy required, pardon the pun

People we are talking about one of the biggest if not the biggest company that have all the things required to mine bitcoin cheaper and with a low cost machine,but i hope they dont get into bitcoin ,otherwise we would see bitcoin being total mined in a short time.But as the most places people against the use of bitcoin i doubt google will direct their bases into bitcoin since they hold a monopolio and no one can try them .

Hello guys,

I was reading my daily news when I saw this:
http://www.telegraph.co.uk/technology/news/12042781/Google-D-Wave-quantum-computer-is-100-million-times-faster-than-your-PC.html

If you don't want to open this link, the title is: "Google’s new quantum computer is '100 million times faster than your PC". They also say "It can answer certain algorithms in seconds rather than years". 

I'm kind of worried, but I don't know if I should be, what you guys think about this? I don't mine but this could affect me somehow if Google decide to use it to mine Bitcoins 
(any language mistakes? Sorry for that, english is not my native language).

good news,yes i said that is good news for me,and i wish someday will try that D-Wave Quantum computer,and about bitcoin,we dont have to worry about that,i'm sure,even google use that computer for bitcoin miner,they will use it wisely,and if they mine bitcoin,they should be introduce to all people,that google accept bitcoin,and its a good advertise for bitcoin.

They dont need to say they are working with bitcoin,if they join bitcoin we would see another bubble happening into bitcoin value ,and well this time i doubt the value would decrease .

Google supercomputer can't be a threat because Google is not so cheap to make something vulnerable for anything. Google is giving life to bitcoins era.
Google is giving us the knowledge and experience about bitcoins.

if it can be a threat, bitcoin and most technologies needs to be evoluation

[jethrorn99]

Do not worry about Google hashing for bitcoins. Instead, worry about how will you live your life privately without them knowing every single thing you do through the use of this Quantum Computer to monitor your activities.

That is way scarier than them mining all of the remaining bitcoins to be mined and cracking all the privkeys (the latter of which is close to impossible.)

I think that already happened. Google almost have the monopoly of searching machine, they know everything about you (yes, even the porn you search.)

[helloeverybody]

I would  be very sceptical on the speed claims of this thing, and either way i think nasa and google have got better things to do than try to crack private keys/mine all day.

If super computer get involved in mining bitcoin than bitcoin will be no more decentralized coin and also if these super computer are only accessed by google and some large company other miner will not have chance to get some coin out of mining.

Yes if supercomputer get evolved than it will be threat to bitcoin.

No, you're being paranoid. You're assuming two things: 1. The person is using that search engine; 2. They know who is behind the screen. You do not have to use Google if you do not want to.

No. Just because something might possibly be a problem at some point in time that does not mean that we should obsess about it right now. There are other important matters that require our focus.

[knightkon]

Correct me if I am wrong, but couldn't one of these computers easily be able to find private keys for some of these accounts that have thousands of Bitcoin in them?  There are constantly new technology coming up and I would think that even though these keys are hard to crack right now, would not they be easier to crack with the better technology coming out.

Simply answered, no. This is something that a lot of people seem to believe because of mainstream media + false information spread by signature spammers. It is possible, but certainly not easy.

It will not be able to crack the transactions or anything like that, so you shouldnt be concerened about it interfiering with bitcoin .

I remember reading about how some of the older addresses weren't safe against a quantum attacker, but post 2012 addresses should be safe, I think someone mentioned it before around here but I can't find the actual explanation.
Other than that it's just sci-fi and you shouldn't worry about any of that.

Google's computer is a D-wave adiabatic quantum computer.  It is not a general purpose quantum computer and can not be used to run variants of Shor's algorithm or Grover's algorithm.  This means that it poses no threat to bitcoin, either to signatures or hashes (including proof of work).

[Palinanv]

To most degrees, I would honestly think anything will become a threat if you don't do what you can to look into it and know what you're doing with it. Staying ignorant about a substance or service can be very threatening in most cases.

[Imoote]

I think if google bitcoin mining was highly unlikely, but it does not rule out the possibility could occur
