Quantum Computing

[Anonymous No.19862743]

Can one of you nerds explain this to me? Is this a real threat?

[Anonymous No.19862763]

wouldn't all SHA-256 based security, which is a fukload of stuff, be under threat by this?

[Anonymous No.19862778]

if SHA-256 gets cracked we'll all have much bigger problems than the price of Bitcoin.

It’s like simultaneously pressing all the buttons at once. Long story short: quantum computing obsoletes all existing cryptography. Should we worry? Maybe in a few years

yes

it will be possible one day. but long before that day comes, we will have moved onto much more hardened encryption.
that being said, any cryptocurrency worth half a fuck is transitioning to POS instead of POW for this very reason.
POS is fundamentally more secure for multiple reasons. namely, to attack a POS network, you would first have to invest a significant amount into that cryptocurrency, and as a result of you attacking it, you would plummet the price.
destroying both your initial investment, and any of the profit you wished you obtain from attacking the network in the first place.

Yes, cryptography will become obsolete in the future which indicates anything that is secured through cryptography will no longer be secure and easily become decrypted.

As long as the cost of cracking a wallet is lower than the potential rewards, it's fine.

quantum computers are really good at case-specific functions. the bullshit about google creating a 53 qbit quantum computer was bullshit. currently you can barely get 3-5 stable enough to work with, and in their case all it was able to do was generate a random number between 0 and 253

Quantum proofing crypto is relatively simple, Im no expert so I might mangle the explanation but pretty much they are good at pursuing all courses of action at the same time, all possibilities because they are based on quantum mechanics and a concept called entanglement IIRC, anyways until you verify something, these single particles (theres 2 of them, and 1 for a control, so 3) are both states at the same time, 1 and 0. So the computer is able to think in both outcomes at once.

A quantum computer is able to figure out problems that are linear and dont change, a set amount of parameters they just cycle through in a specific way that does not change. Now if you solve a problem, then go and change how the problem is solved afterwards, it cant do that. This is the part thats hard to explain... but Im sure for a programmer its easy to employ when they understand it. If youre just going 1+1=2, 2+2=4 4+4=8, like you see the pattern, it can figure that shit out.

If you went like 1+1=2 2+2=4 4=3=7.. 7+7=14 14+14 =28, like youve broken the set course, solve and multiply result, solve and multiply result, suddenly the result changes from what you multiply, it breaks the quantum computers ability to pursue that course infinitely.

yea I put an = in 4=3=7 instead of a +, said multiply instead of add but you get the idea.

Also it becomes exponentially harder to expand quantum computing because they need to operate in an environment colder than space, possibly the coldest place in the universe.. and the more qubits they add the hotter it gets. They just made some sort of advancement allowing it to operate in hotter temperatures, by something like 5x hotter but its still multiple times colder than space. Its some ridiculous number like 0.005 kelvin up to 0.025 kelvin

[Anonymous No.19863233]

Btw I can only think about the absurdity of leftists ever thinking niggers could come up with these scientific advancements. Humanity really would be nothing without whites.

Yea but they need to use a multiple stage process to cool each one successively colder to achieve this insanely low temperature almost at absolute zero, kelvin is true temperature and there is an absolute lack of any heat at theoretical zero, I dont think it exists.

Quantum encryption is likely to emerge ahead of consumer-grade quantum computing. Entropy can work both ways... If that's the case you could have encrypted bitcoin wallets that are entangled with the cells in your body that are essentially unbreakable.

Abandon your attachment to Bitcoin, it cant even scale its blocks without retarded solutions like lightning network. Quantum protection will come but not on Bitcoin.

/sci/entist here, stop talking shit about shit you don't know.
SHA-256 is a very common encryption method uses to turn any string into a random 256 digits. It is impossible to go backwards from these digits, and so is used by bitcoin to verify transactions without ever revealing the bitcoin itself.
SHA-256 being cracked by quantum computing would mean you can, in fact, go backwards from hash to key. This would spell the end of bitcoin. This is quite a while away in the future, though, if it is reached at all.
People are quickly realizing quantum computing is little more than a meme with few niche uses mainly in cryptography. We're currently at 50~ qubits, and due to the nature of qubits it will likely take exponential effort to add more (unlike normal bits, which you can often simply copy/paste to double the amount. Qubits require being in superposition with each other). Reaching 2500 is a pipe dream, and unless a real use for quantum computing is found it will likely take a century or more to be done. And if you would click on that little lock symbol on your URL bar, you might read that 4chang uses AES to encrypt its data. AES-256, unlike SHA-256, is almost entirely quantum-proof. A quantum proof SHA-256 substitute can surely be found. So what good is quantum computing?

There is quantum proof cryptography. But anything that doesn't update their hashing algos is going to be fucked lol

No you wouldn't you dumb fuck. You would just hack the wallets until you had majority of coins and then do whatever you want, actually much less secure in that regard but overall it's basically the same.

Need I remind you that as recently as the early 80s IBM was working under the assumption that home computing would never catch on?

[Anonymous No.19865302]

>>19862743
The answer is yes.

quantum computers can crack encryption much much faster than traditional pcs, its just a matter of time before a powerful enough qpc comes along

Bitcoin is finished regardless of quantum computing. Bitcoin cannot work without block rewards.

That day is far far away but there is a bigger threat nearby. The quantum computing of near future may not break the bitcoin cryptography but it will most certainly break the wallet seed system. And in that event, well you know what'll happen

Nigger, people have troubles having double digits of qbits working.

Also, last year a lot of proofs came out that showed there a ton of quantum algorithms that were thought to be better but actually they are outsped by a class.of classical algorithms, so another blow on quantum computing being some magical shit.
