Now My Question
What impact could advances in quantum computing have on the security and integrity of the Bitcoin blockchain? Moreover, what efforts need to be made within the crypto community to address potential vulnerabilities ?

The answer to your question is in your topic already. With the improvement in the quantum computing ecosystem, it will be challenging to keep the existing cryptographic algorithms. Many security breaches could happen in a short moment and by the time we notice it, it will be too late. The impact is going to be mostly negative on the blockchain if it falls into the wrong hands.

The solution however is coming up with a way to prevent this from happening. You cannot come up with a solution overnight. You will have to constantly keep up to date with everything that is happening in the progress of quantum computing. Acting based on the progress and creating an anti quantum mechanism is the only way to do it.

For now, it's a question of Qbits vs. Years, that is what allows zero worries in the short term and after that, although it may not seem like it, designing the algorithms can take a few more years...

In any case, we cannot be so presumptuous with bitcoin, and we must put ourselves in a priority queue, because when Qbits levels reach, we will all be in danger, not just those who have bitcoin.

I won't answer you because you have copied the whole thread of someone else from Bitcointalk and now posting it from your account and sharing the link only.

I would suggest you to come up with your own ideas instead of copying someone else's threads, it's an act of plagiarism because you have copied the whole thread and sharing the link as reference.

You can basically quote some parts of his thread or give credit to him for the thread and then create your own thread with your own questions, that would be much better.

As for DEX, do not rely on it. A professional hacker with simple tools and high experience can hack it, as happened several times, so it is not considered safe at all.

Okay thanks for the easy to understand explanation
If I may know what is the SHA-256 algorithm?
It is true that for Dex it has happened too often and it happens to the EVM network if on the IBC and ICP networks there doesn't seem to be anything maybe I don't know.
Is it really that easy for the EVM network to be hacked?

Ohh, So you mean with Qbits, evolution till the algorithm design there are some years gap. Why do people think that Quantum technology will be only used to threaten Blockchain technology?

hmm, this technology is mainly focused on getting more precise measurements that can be used in research work, medical equipment Environmental analysis and etc, etc, I'm not saying I know a lot about Quantum computing but still, I can say it was not only adopted to destroy crypto and encryption algorithm.

I can assure you that quantum computers are not threat to bitcoin, and cryptocurrencies at large, at least, not at this very moment, it will take several years of development before quantum computers get to the stage or level where it may likely have a chance at becoming a threat to the existence of bitcoin and cryptocurrencies, and before that time arrives, trust that bitcoin and cryptocurrencies have also developed stronger blockchains and wallets that are quantum resistant.

I actually have a well detailed thread on this topic on bitcointalk, I am just going to find time to move the same thread here, so that users here can read and learn as well.

Quantum computers (the real ones) are still far from working at full capacity. Those desktop and laptop computers that some companies sell (very expensive) with a few qubits are not actually quantum computers. True quantum computers still do not have much computing capacity, to give us an idea, the Qilimanjaro Quantum right now has a computing capacity of 5 qubits and they hope to reach 30 in 2025. IBM says that "soon" they will have one available with 100,000 qubits, but that's mostly marketing, since it's crazy to achieve that capacity with current technology.

Regardless of when quantum computers become accessible to the general public, Bitcoin will be more than prepared to keep everything running as usual. You have to think that where there is quantum computing, there will also be defense at the same level, something applicable to Bitcoin when the time comes.

If I may know what is the SHA-256 algorithm?

SHA-256 hashing is a type of secure hashing algorithm (SHA). Hash algorithms are used to convert data into a fixed set of letters and numbers called a hash. Hashes are used to verify the integrity of data and ensure that it has not been modified during transmission over the network. It is an essential part of the Bitcoin protocol. It is used for Bitcoin mining and generating Bitcoin addresses. And also to secure transactions and account proof of work (POW).

SHA-256 hash algorithm is considered robust and reliable due to its mathematical design and sophisticated security. So far no one has been able to crack the algorithm. Because of this reliability, Bitcoin relies on SHA-256 to secure its network and keep transactions safe.

Its main problem is that it consumes a large amount of energy, and this is what governments exploit to discredit Bitcoin.

Before discussing, I think we should refer to some real data about the development of quantum computers and the safety of the Bitcoin blockchain:

"According to calculations, an honest quantum Bitcoin miner would need around 10,000 qubits quantum computer without considering quantum noise. That should be enough to fit the transaction data into a block and calculate hash values.

A fork may be needed to make Bitcoin more resistant to quantum attacks. I.e., 20 million qubits at worst would be required to break a 2048-bit RSA encryption, commonly used nowadays for protection, such as credit card data.

IBM plans to offer 433-qubit quantum systems in the near future and to unveil the world’s first universal quantum computer, with more than 1,000 qubits, this year. Also, the company expects to produce a quantum computer with more than 4,000 qubits by 2025^[1]."

These figures show that for many years to come, quantum computers cannot defeat the Bitcoin blockchain, while the Bitcoin blockchain continuously becomes more secure as the Hashrate continuously increases.

A fork could make the Bitcoin blockchain thousands of times more quantum-resistant than it is now, which would be enough to protect the Bitcoin blockchain and the entire crypto market 

In addition to the limitations of the Quantum Computer's power, we have many other issues to consider. Assuming Quantum Computer has strong development and governments can successfully attack the Bitcoin network, Bitcoin is not the subject of their attack.

In addition to Bitcoin, SHA-256 is used to encrypt information in military communication systems and also banks^[1,2]. Therefore, if possible, Quantum Computer will be used to attack military communications systems to steal confidential information, or attack to appropriate assets in large banks. At that time, we will also have more worries in life, not just worrying about Bitcoin 🤣

Maybe for this reason in the past in China it was forbidden to mine Bitcoin, I have read news about the problem of the power that is spent very large to mine Bitcoin or maybe there are other reasons I don't understand but due to the news that bitcoin has decreased by causing all coins to decline by a dozen percent but after a few days news came out that China was allowed to mine Bitcoin again.
I think this is like a whale game that wants to buy Bitcoin at a low price or is it true?

Advances in quantum computing pose a potential threat to the security of the Bitcoin blockchain. Especially because of its ability to break widely used cryptographic algorithms. There is a risk of compromise in the current encryption methods we commonly use to protect Bitcoin transactions. I think one of the highest efforts in the cryptocurrency community needs to be on developing quantum resistant cryptographic algorithms. Because our private keys can be vulnerable to quantum attacks.

Quantum computers are not so common that every hacker has them, even the ones that exists are only used by big corporations like Google, IBM, etc. They are also using these computers under specific conditions, where the room temperature humidity etc. is maintained regularly for the proper working of Quantum computers. In simple words, the whole place is isolated to run the computer. And running such a computer under the nose of law and authority is a difficult task for a hacker.

Unless the hacker has a lot of money to manage all these things. I don't really know how much potential these Quantum computers have, because they are under experimental use and till now there are many types of quantum computers are being used like photonic, superconducting, etc. And none of these are able to cause any kind of trouble to BTC encryption. And breaking with encryption with such beta computers is still a question on there potential and I don't think they have the capability.

There is no doubt that Bitcoin mining consumes a large amount of energy. This is true, but this is not the real reason for banning Bitcoin by China or other governments. This is just an argument they use to justify their attack and ban on Bitcoin. There are hundreds of factories of worthless things that consume large amounts of energy and cause pollution work With the approval of governments without prohibiting them.

The real reason is that governments hate Bitcoin because of its decentralization and preservation of privacy. This is what governments hate because they want everything under their control and reject privacy.

I am really very sorry. I was feeling very guilty after posting this, so I tried many times to delete the post. But there is no post deletion system in AltCoin Talk yet. So I am forced to give the copy link from where I copied it. I will definitely post on my own in the future. Because we need to know a lot. I am very sorry. I apologize to everyone.

Hehe... What's the matter here guys.. Seems like I've ignored the whole thread by OP and just made my post based on the fellow's opinion haha that's weird and looks like the next time it's a lesson for me to tag out the copy posters... Buddy, I'm not aware of the copy-paste rules (Palgrism) on Altcointaalk but I can assure you that your account could have been already banned ...

Anyway If you've accepted and apologized lets wait what other's say on it...

So, like I promised in my comment quoted above, I've posted my thread on why quantum computing can never defeat bitcoin , not now, and not in the nearest future, yeah all can head over to https://www.altcoinstalks.com/index.php?topic=317333.0 and read it, and also post your thoughts, questions, opinion in comments.

I highly doubt if any of us currently here now would still be alive to witness when quantum computers would have been well developed enough to pose as a thread to bitcoin's existence.
