Will quantum computing kill crypto?

So quantum computing will allow for cracking encryption incredibly fast, so fast that any encryption will be pretty much worthless.

What's stopping any party in the very near future from just mining all the remaining bitcoins for themselves as well as being able to impersonate owners of wallets to send funds anywhere they want?

Won't all crypto just blow up when quantum computers become operational?

just buy quantum coin

If quantum computing becomes a problem crypto can just hard fork with a version of encryption that is resistant to quantum computers.

No, quantum computers will do all normal computations slower as additional cumbersome code is needed to account for the innate randomness in its workings.

Quantum computers are made for simulating particle physics very precisely by replacing a algorithm to simulate the randomness in quantum mechanics with the actual randomness inherent to quantum mechanics. It's a very good Schrödinger equation solver

I'm no expert on encryption or quantum computing, but isn't the whole idea behind quantum computers that they will be able to crack encryption incredibly fast?

There isn't any way to encrypt something so that it is immune to quantum computers, that would kill the whole concept and there would be no push to develop quantum computers.

No that's not the case. I've been to a presentation about quantum computing from a large international that is working on a 20 qbit quantum computer.

The way bitcoin mining works is that it wil give a difficult puzzle to all computers tgat are mining and the one who solves it will get the honer of mining the block.

However. The difficulty of the puzzle is based on the time it took to solve the last one. As such. The puzzle will be so difficult that it will take the quantum computer just as long to solve as the last puzzle for the other computers.

Because of this the quantum computer will be faster for exactly 1 block.

>Quatum computing

This is meme. It cannot be done, crypto is the future

i've always had this doubt

Ah, I see. It'll just up the standard "solve-time" for this puzzle when most people begin using quantum computers to solve them. It's like if we all became twice as smart, the average IQ would still be 100.

But what about security? A quantum computer would be able to impersonate wallet owners and move funds around at will (stealing them essentially), since it's all protected by encryption. The encryption "locks" will essentially be worthless and crypto will become more insecure than physical ones.

and the second block, and the one after that for 10 years until bitcoin is dead and everyone can finally get their hands on a quantum computer somewhat cheap.

normal computers will have a better encryption than quantum ? Probably we will have to create an encryption on quantum computers, right ? Quantum X Quantum. We have more 20 years of crypto ?

If there's an quantum computer, no finance will be secure man, quantum must be used to do good otherwise it will destroy the world

Quantum encryption. Stop and think for a minute before you talk, we're talking about using quantum computing to mine bitcoin blocks when it could be used to crack into any bank world wide and drain billions if they keep running the same encryption they have now.

Everything scales, computer jumps, encryption jumps.

Quantum computing will be used to break down things like human diseases and questions to space and time. We future now.

there is already quantum resistant code, and iota is the best solution to the blockchain sha256 crisis

I'm not to sure if Bitcoin uses quantum resistent encryption. If not the problem could be solved with a new coin or a hard fork. This would be unfortunate but it's not the end of crypto.

It might be more difficult to mine bitcoin but since it won't be actually mined faster and only be more difficult to mine it won't increase the inflation compared to now. So it could mean the end to mining at home but the coin won't decrease in value because of it.

>There isn't any way to encrypt something so that it is immune to quantum computers
yes there is

Physical property, precious metals, would become more relevant (than they already are).

How would this work? Is there anywhere I could read about this?

Transactions will need to become about 50x larger to become immune. That's all.

read up about post quantum cryptography.

Its been researched since like the 90's dude.

Maybe having 200 mil extra state possibilities at 64 bit will break the world but then you just take the current numbers and swap them for bigger numbers.

200 million times the state possibilities*

won't be all bitcoins already mined before quantum computing gets that powerful and available?

let me explain this easily: a quantum computer is just a more powerful computer. it can just work faster. much, much, much faster than normal progression, but just "faster" all the same. contemporary encryption is made by traditional computers in such a way that it takes far too long for traditional computers to ever solve. quantum encryption will be made by quantum computers in such a way that it takes far too long for quantum computers to ever solve

think of it like this: if someone invents a new superhard and sharp metal and makes a sword with it, that doesn't mean that no shield can block it. you just need to make a shield with the same metal as the sword

But if the group with this computer wants to profit over everybody ?
Everything must be opensource man, that's the only way humankind can progress.

Last bitcoin will be mined sometime around the year 2140.

A quantum computer won't have any more computing power than a traditional computer. It would provide no benefits for playing games or watching movies, for example.

The benefits is that it can run certain algorithms that allow for faster solving of certain problems. A quantum computer can evaluate many possibilities at the same time to find out which is most likely to be correct. A traditional computer would check each possible solution and test them out manually, essentially brute forcing for a solution. This makes a quantum computer fit for searching for key primes that are used in encryption, essentially making traditional encryption worthless.

Maybe you could use a similar method of searching for the primes used in encryption?

As far as I can see nobody know what they're talking about in this thread.

This is true but quantum computation doesn't evaluate multiple possibilities at the same time.
Quantum computation is able to compute continuous plages of values instead of discrete arrays. That's the difference.
It's better for precise physic models (such are climate and weather) and analog stuff. Quantum computing won't do anything for cryptography.

BLOCKFOLIO DOWN??


REEEEEE

Here's a vid to help explain it.
