So, quantum computing is supposedly a big threat to Bitcoin, which is worth around $2 trillion. BTQ Technologies claims to have a solution to this problem.
Right now, a major concern for Bitcoin is the emergence of quantum computers. People are saying these quantum machines could potentially crack the Bitcoin network and really mess things up. On the flip side, some believe Bitcoin actually stands strong against quantum tech.
I've come across a news snippet about this. I'm curious to hear what the community thinks about how serious this threat is at the moment and if it genuinely poses a risk to Bitcoin.
By the way, BTQ Technologies is promoting a quantum-resistant Bitcoin testnet.
Quantum computers pose no realistic threat to Bitcoin in 2026.
Breaking Bitcoin's ECDSA encryption would require something around 2-3 million error-corrected qubits, but the most advanced quantum computers of today have only around 1,500 of physical qubits.

By the time it will be a reality BTC will be ready for it.
Nothing interesting is going on so many have gone back to talking about the quantum computer FUD
A similar topic today
Preparation for the Quantum era.
Currently one of Bitcoin biggest challenges is people not understanding what it is.
Like I usually say, I still look forward to the day i would see a thread or post online
About Quantum threats to banks and other institutions and not Bitcoin.
People won't likely talk about systems that's less secure, the banking system has failed and normal hackers can even penetrate their server and easily steal money online without their notice so thiose anxious people know that the quantum computers can easily beat the security of the banking system and need a tougher challenge to talk about.
As we all know, the Bitcoin blockchain has never been hacked or compromised which is why many people are so anxious of whether the quantum computers would be able to break it's security, well I feel the security of the Bitcoin blockhain was built to withstand future threats but only time would tell.
To play the Devil's Advocate - What makes you believe that Bitcoin will be ready for coming of Quantum Computers?
What makes you think that the Hard Fork to Quantum Resistance would be easy, and that ALL full nodes will upgrade their software in lock-step?
¯\_(ツ)_/¯
Another Quantum FUD. Unfortunately many do not know how Quantum computers can pose a threat to Bitcoin, they are influenced by the mere saying that it poses a threat. All the stories are the same, with a question that still remains unanswered, which is "when" and "how"
Quantum computers cannot be a threat to bitcoin in this 2026, and before it will be a threat we will see Anti-computer technologies that can fight against quantum computers.
i agree the quantum threat seems overblown for now. but it's good we're discussing it. even if breaking ECDSA is years away, it forces us to think about future-proofing. i'm not sure about the hard fork process either, but i think we'll find solutions when needed. anyway, it's better to be prepared than caught off guard later.
I believe that with the leading researchers and computer scientists in Quantum Computing getting more and more optimistic that it's coming sooner than expected based on what the milestones that they're seeing, it might not merely be another "Quantum FUD" anymore.
It will be more than a decade before an actual Quantum Computer could break Bitcoin's encryption, but who said that we can't discuss that in the community, and take this matter more seriously.
We know that RSA keys and Bitcoin legacy addresses are cooked, but will it also be able to crack Ed25519 keys that use ECDSA?
A lot of malware seems to be using that, especially ransomware, so this could provide a temporary breathing room.
Last time i checked this company, i unable to find relevant both source code and proof[1]. It seems there's little improvement since they release block explorer of their testing network, although i would remain skeptical towards this company.
