Topic: Is this the end of Bitcoin Encryption? - page 2. (Read 2203 times)

this is my point exactly. there are different forms of encryption and not all of them are easy to break with a quantum computer. if necessary bitcoin can quickly adopt and to be honest there are more lucrative goals then bitcoin once you can crack the encryption.
but wait there is more. there are quite a lot of addresses so this also gives you even more protection.

Another question:
Would this thing be able to mine bitcoins?
And how fast would that be?
If it has such a high calculation capacity, maybe you could earn more by mining than renting it would cost you.

I would be interested in hearing what one of the core developers think about quantum computing and how they think it will affect bitcoin. Are the core developers taking this seriously or are they taking this all lightly? If they are taking it seriously, what are their plans for bitcoin's algorithm and how soon do they think they can change it?

it has to first make ECDSA insecure, then it has to become a threat to it. the 256-bit elliptic curve that bitcoin is using is still considered secure and from what i have read from proposals and topics about the security of encryption i know that it is possible to move to a more QC resistance addresses.

I also wish that video was not true. But as you said everything is easy to be hack, No way, it is not too much easy as you said, you know if everyone can do it so why You and Me not hacker. Only some hackers can do it. But i am agree with it,that it is fearfully thing. But we can't do it  because we have been achieved that place where we never come back and also we can't any work without computers.

even if the power of this quantum computer is enough to break bitcoin encryption is not the end because this computer is not available to public or hackers to hack bitcoin.

and also if i am not mistaken we can move to a stronger encryption other than sha256

Agh.  That is the reason why I did not continue my course on Information Technology!  I was amazed by what computers and highly intellectual people can do.  Just typing some codes and everythibg can be hacked, traced, and destructed by simple codes.  I wish that video was not true or I just wish that it will be used for a good purpose.

Let us not worry about the quantum computers there are both advantage and disadvantage that it may bring but whatever it is lets be ready when they launch it. It may endanger our bitcoins or it may see all computer related activities online. But mainly the purpose of that computer is not mainly to look at bitçoin but to spy other countries. The computer just disguise itself as something unique but actually its a spy computer for CIA use.

This is my first time is hear about the quantum computing but after reading all of the post in this thread I can define that is will become a bad thing for us.  ?

Let's hope that wise people will keep the evil people from using it to destroy us all.

Quantum Computing could help us make something even better than Bitcoin.  At least for all of us who stay informed.  I am confident we would be able to ride that wave to success, whatever quantum computing brings us.

The video suggested 15 years before the Quantum Computer became fully functional in all its potential ways.

The video suggested that because of the different style of operation, current encryption will be among things that will not be a hindrance to the Quantum Computer. The QC will run right over regular encryption. A whole new form of QC encryption will have to be developed that will not be touchable by regular computers.

I got the idea that the things that he was talking about were actually in evidence, even though it is small evidence currently, and that this is only the beginning of what they will be able to accomplish if they don't run into some unforeseen hindrance.

My fear is that they will awaken the devil out of the Abyss, and that he will have the strength of quantum computing experience from his past, and he will take over the earth with an iron fist.

Of course, if that happens, Jesus will come and destroy Him, and take the saved people to Heaven.

when the inventor of D-wave cannot show any real world results, eg what D-wave has already done over the last 9 years of expansion
when they say D-wave is 500,000x more faster than it was 9 years ago, but uses the analogy of a 1mph donkey vs 2000mph jet (yes 2k not 500k).
where the only usecase they can think of is fiction of parellel universes that no one can see themselves and have to blindly trust 'reports' of D-wave..

all in all it sounds like it has never done anything and wont do anything
they cant even grasp reality to talk about REAL results or potentials.
just the wishy washy blackhole theory of time travel, worm holes and alternative universes.


its almost like all them Nasa images of far away planets where they show computer 3D art of oceans and land on other planets.. but the real science 'results' is just a spectral range of infrared that is close to the same spectral range that earth sits at. and nothing like the 3D art they publish as their 'findings'

all in all im not worried. i dont think D-wave will do much real world work. and just wasted on 'science theory' that cannot be proved and thus only stands as fact because no one else has the same tech to debunk it

if only the video talked about gene mapping. or calculating the best drug combinations to fight and cure cancer/hiv.. then i would have thought D-wve was a real thing... not the alternative universe theory the guy wants to waste time on that cant be proved or help or be useful

i think "theoretical physicists" should never get anythink more then mimimum wage.

Encryption theory would still apply. It's just that the computer will be able to compute at levels multitudes faster than normal computers. And it will be easier to get much much more powerful computers. We just have to step up our game.

I sure hope not because I wanted to start to get into encryption theory and take a job doing it. 

I don't think that quantum computing is a pipe dream. It's just not ready for mass use today. But I can imagine that it will be in 10-20 years - today's computing technology wasn't ready in a few years neither. The quantum effects to be used in a QC are well researched and there's enough motivation to implement them in practice, because the advantages could be enormous and the current technology is approaching the limits of miniaturization.

If cracking SHA256 becomes a reality, Bitcoin's crypto will need an update. In my view, it's reasonable to assume that there will be prior indications for this and plenty of time will remain to roll out an update.

Nothing is forever, progress goes on. That's especially true in the highly competitive field of encryption.

ya.ya.yo!

Notice that the talk said that the computers are so expensive that people will be able to rent time on them, but never be able to afford one. Let Bitcoin encryption change to match quantum computing level security. Then rent time on the QCs for use with your Bitcoin. Security enhanced by Quantum Computers.

Quantum computing is a pipe-dream and if this becomes a reality, this computer will not only be able to hack Bitcoin, but also ALL encryption using

SHA256. This will include all secure services on the internet and also secured banking services. You have to know that we have the option to increase

the level of encryption, but that will have it's own challenges.
