Be careful what you choose to believe about Quantum

[Somegory]

Trust me, quantum computers won't just come and wipe away all the efforts that has been made so far, some countries are already naming themselves the homeland of crypto, you expect something like quantum computer to come and ruin all that?

With the way things are going with this quantum thing I can't help but believe that some people will have to let go of their Bitcoin to avoid the quantum thing.

All it will take is just a Tweet.

And few days or weeks later they will say a fix is finally coming for Bitcoin and other coins, and stupid you already dumped your Bitcoin.

Isn't this a perfect FUD to make redistribution of Bitcoin happen? Just imagine a president of a country tweet that quantum is the end of Bitcoin, what do you think would happen?

A perfect clean out if you ask me.

People need to be careful with what you digest about Quantum computer.

Understand that quantum threat can be fixed, there are too many things relying on Bitcoin today, ETFs wouldn't have gotten approved if quantum threat is very high.

I always read about bitcoin quantum threat but I did not read about the banks and other centralized business which will be greatly affected and they are not yet shifting towards the post quantum period.

I have said it in a post before that quantum computers cannot affect bitcoin, it will affect addresses with exposed public keys but it is preventable if you do not use your bitcoin address more than once.

In 2010, one might have said Bitcoin had no value. But what is its price now?
In 2025, it reached a high of $126,000.

Back in 2010, the narrative circulating in the public sphere was that Bitcoin was created for illegal activities such as terrorist financing and other illicit transactions. Not to mention the claims that Bitcoin was being used as a get-rich-quick scheme.
Quantum computing emerged in 2026, and as this technology continues to advance, people are beginning to reconsider owning Bitcoin.

Don’t forget that Bitcoin is a decentralized system that doesn’t require a third party. It was created as an electronic cash system designed to facilitate transactions for its users.

You still don't get it? In quantum you find the realest state. You choose to put the keys on the table then it's where we find them.

Beyond bottleneck architecture. It's my 10 cents of speculation on the subject.

Google just want to take a huge piece of the entire supply. They're quite late to do it now and so, anything that they might say like quantum computers can crack bitcoin's network is such a big deal for most. While they're known for it, this isn't new to us. Coming from known names, celebrities, investors and prominent people in their own niche. They've said a lot of bad things to Bitcoin but later on, we've just known that they've taken a large part already and bought it. So, if this turns out that this matter that came from Google is a bluff, we know that they just want to invest and the large investors now are not even sweating upon hearing them.

Satoshi Nakamoto replied about it years ago, let's see.

However, if something happened and the signatures were compromised (perhaps integer factorization is solved, quantum computers?), then even agreeing upon the last valid block would be worthless.

True, if it happened suddenly.  If it happens gradually, we can still transition to something stronger.  When you run the upgraded software for the first time, it would re-sign all your money with the new stronger signature algorithm.  (by creating a transaction sending the money to yourself with the stronger sig)

Two big questions: whether quantum computers in 2026 can be powerful enough for doing that compromise successfully; and the Bitcoin developers already have anything in hands to fight back - upgrading Bitcoin protocol and migrating to stronger signature algorithm.

I don't see the threat is powerful enough to succeed now while Bitcoin developers have still been working hard for improving Bitcoin protocol with time.

This is all about the Bitcoin network and the protocols in which it works upon, once we can have a secured network with bitcoin and this remain a consistent experience as it has always been, then I don't think there is anything to scare us from the effect of quantum on bitcoin network, even though there have been a lot of accusations that such could be a threat to bitcoin network, but we are still waiting to see if possible or not now or in the future to come, while bitcoin network remain the same as always.

In theory yes quantum is insane enough to wipe out entire encryption and I just ask chatgpt that there is a possibility of an AI with the brain of a quantum computer. If this really exist there is always two choices good and bad.

Bad side : We are just dead, I mean in a lot of possibilities human might the problem of this world, System like crypto are breaking down.

Good Side : New material, human could be more advance peace everywhere there will be no human problem like poverty and homeless and there is also an option to defend quantum with a quantum

[Mate2237]

I don't know why this whole issue of Quantum computing is an issue, it has been said over and over that Quantum computing is not a threat to the Bitcoin community. I believe that all these noise about Quantum computing is a way to distract people from their interests in Bitcoin. No body should get discouraged due to so called threats from Quantum computing.


Bitcoin has remained threat free right from its inception, I believe that this is not the first time that people have tried to breakdown the Bitcoin programming language there has been threats and Bitcoin has been able to stay undisturbed Quantum computing is just another thing that, will pass away very soon.

[macson]

This is why whenever someone talks about quantum computers, I will continue to refute what they say. I believe that although quantum computers have the potential to be a serious threat to Bitcoin, the current level of quantum computing is still far from breaking Bitcoin's encryption. So, whatever people say about quantum computers being a threat to Bitcoin is just FUD used by interested parties to scare people and make Bitcoin seem unprepared for the threat of quantum computers.

[purple_sparkles]

In my opinion, we still have some time before quantum computers truly become a threat to bitcoin and its code, and we will definitely see warning signs, the most important thing is not to miss them. It’s hard to say when this will happen, since it’s unclear how a real breakthrough in quantum mechanics would affect the pace and direction of development. So we need to stay alert and keep our eyes and ears open.

What do you want to say about what Google talked about quantum computers threat to bitcoin?

According to a whitepaper released by Google Quantum AI researchers on March 30-31, 2026, quantum computers could pose a significant threat to Bitcoin by breaking its encryption, with a potential timeline for this capability to arrive around 2029.

Although, I can not be affected at all unless the threat later drop the price of bitcoin significantly but which I think will not be possible. I think I can not take what Google said as a joke.

[red4slash]

The existence of a quantum computer which has always been a fairly busy rumor since the last few years is sure to have an impact, especially for psychology in our minds as bitcoin holders but this is not what should be used as a big enough fear actually because until now there has been no proof of this and until now it is only still speculative about indications.

Being on guard for the worst possibilities about quantum computers is very good but that does not mean we have to believe the news that is very wild at this time because it is only one of the many possibilities that can happen.
It is certain that the existence of this quantum computer must be watched out for but making this a source of fear and we believe in all forms of exaggerated news is actually quite ridiculous.

bitcoin has been strong all these years with no signs of weak points as many people try to improve it further. anyone scared of quantum threats now are just panicking and not really grasping the idea. i continue to believe in bitcoin and its design

The existence of a quantum computer which has always been a fairly busy rumor since the last few years is sure to have an impact

Folks once again it must be stressed that there are NO functional QC's in existence (yet).

Yes great progress has been made since 1985 when the first Josephson junction transistors were created - they were the first physical proof that a quantum computer could be built. However, to-date only components that will eventually be integrated into a functional QC are being built and tested along with ideas about programming it. Compare it to say, developing the designs of DRAM and logic circuits independently - from scratch with no earlier designs to reference - so they can later be integrated into a CPU and then later all be tied together to make a computer. Oh, btw you also have to create an OS for it as well...

As that Google white paper stated, right now QC developments are still at the chaos stage similar to automotive progress in the very early 1900's with several companies working their own ideas about what a car will be and how they will work. Many if not most of the QC design ideas will come and go before workable solutions are settled upon.

Something folks need to realize that in Academia and Corporate research there is a saying: "Publish or become irrelevant". That translates to; find a relevant topic (preferably one that will catch attention), do some often biased research that you can extrapolate from and write about it. If you don't publish you may lose funding. The Google paper is about them improving algorithms to reduce the number of qubits needed for breaking current encryptions and nothing more. In the case of the Google paper and other similar ones about QC they carry on about What Could Be but gloss over the hurdles that have yet to be solved before their predictions can happen.

Ever since I started hearing about quantum computers and even did a little research on the topic, I didn't find any risk it poses to Bitcoin that hasn't already happened, because I believe it would only make up for volatility in the market because of the fud and FOMO it would create and am sure that it would be more like a tool just as we have Ai bots integrated into the Blockchain systems to facilitate efficiency or delivery and credibility.

The bad would take advantage of it no doubt,  but the good quantum computers would do is what would make it gain investors confidence.
Investors these days are looking towards AI token and technology which is more of an advancement that is well understood and easily integrated for different uses and I think quantum computers would do same but with strict policies that make it compliant to users both newbies and professionals all the same.

People need to be careful with what you digest about Quantum computer.

Understand that quantum threat can be fixed, there are too many things relying on Bitcoin today, ETFs wouldn't have gotten approved if quantum threat is very high.

But if it hasn't come doesn't mean the effect of it isn't yet measured? The thing is with human nature is that we are all paranoid if something isn't totally understand and that makes us worried on it. Did Satoshi anticipated that quantum computer will be a threat in the future or he miscalculated that one? I think if devs really want to counter quantum computers then they need to move fast to make these quantum computing security measures than the innovation of quantum computers. I think yes it could be a FUD but there could be some real threat behind it.

I think that’s the essence of Bitcoin: a community that supports it, understands its position, and knows who to trust. Being here (BTT) isn’t just about posting or reading. The existence of this forum should play a key role in situations like the one you mentioned.

While it’s true that this is a reality affecting all cryptographic systems (not just Bitcoin) it’s reassuring to know that it’s being discussed, that there’s a community of developers working on BIPs and whatever else is needed to secure Bitcoin’s future. They are prepared, not scared.

From what I understand, as a user (not an expert), there is an ongoing development process. There is still time; but it’s becoming increasingly precarious to find... time.

As much as I understand your sentiment and agree with a "non-panic" approach, but the argument that "Bitcoin is too big or too established to fail" is not a good one. That's emotional thinking and what we need is a sober, factual assessment.

I think Bitcoin community is too optimistic and too quick to shrug off any potential threats, either because they are said not to happen in the near future, or because there's a belief that there will always be someone who will fix any problems.
Bitcoin is still a decentralised network and it requires some involvement and a more active role from its participants. We shouldn't just take things for granted and assume someone else will do the hard work, while most of us focus on watching the price chart.
At the very least, we should keep track of the current development issues, rally behind good ideas, and voice objections for potentially harmful solutions.

I have my homework to do on Bitcoin's quantum-resistance, but, from what I've heard, it might not be as easy fix as some paint it to be.
