The birth of quantum encrypted virtual currency is difficult to predict accurately, as it relies on the development and maturity of multiple technologies, including but not limited to quantum computing, quantum key distribution (QKD), post-quantum cryptographic algorithms, and the evolution of blockchain technology itself. However, we can make some speculations based on current technological trends and developments.

1. **Advancements in Quantum Computing**: Although quantum computers are not yet a threat to existing encryption algorithms in the short term, they are developing rapidly. As more qubits are realized and error rates decrease, quantum computing capabilities will gradually enhance. However, it may take years to reach a level that can support quantum encrypted virtual currency.

2. **Quantum Key Distribution (QKD)**: QKD has already been implemented in laboratory environments, and there are some commercial products and services offering limited-range quantum secure communication. However, integrating it into a widely distributed blockchain network still requires addressing many technical and infrastructural challenges.

3. **Post-Quantum Cryptographic Algorithms**: International standardization organizations (such as NIST) are working on developing post-quantum cryptographic standards. Once these new algorithms are standardized and widely accepted, they can serve as a foundation for building quantum encrypted virtual currency. NIST expects to complete its selection process for post-quantum algorithms around 2024.

4. **Adaptation of Blockchain Technology**: Even with post-quantum cryptographic algorithms, existing blockchains will need to be adjusted or upgraded to be compatible with new security mechanisms. This may involve hard forks or the development of entirely new blockchain platforms.

Considering the above factors, if all relevant fields can develop smoothly without encountering major obstacles, we might see preliminary forms of quantum encrypted virtual currency emerging within 5 to 15 years. However, this estimate is very optimistic, and the actual timeframe may be longer, depending on various unforeseen factors and the speed of technological breakthroughs. Additionally, market acceptance, regulatory environment, and other factors will also influence the practical application and popularization of this new type of currency. $BTC $ETH #量子计算机

Billionaire Chamath Palihapitiya: It would take about 8,000 Google quantum chips to crack SHA-256

Billionaire Chamath Palihapitiya stated in an online meeting that approximately 8,000 Google quantum chips would be needed to crack SHA-256. Earlier, Chamath Palihapitiya posted on X: "Quantum computing poses a risk to v1 encryption methods, but the timeline is very unclear and not in the near future." #量子计算机 #谷歌量子 $BTC $BNB

On December 10, Google introduced its latest quantum chip, Willow, on its official blog, reigniting discussions in the crypto community about quantum computing attacks. Will quantum computing undermine existing encryption security mechanisms, particularly posing a threat to mainstream cryptocurrencies like Bitcoin?
Satoshi Nakamoto discussed this topic as early as June 14, 2010, saying:
"SHA-256 is very robust. It is not a gradual improvement from MD5 to SHA1. It can stand strong for decades unless some sort of large-scale breakthrough attack technology emerges.
"If SHA-256 is fully compromised, I think we can reach some consensus to lock in the 'honest' blockchain before the problem and adopt a new hash function from that point.
"If the hash compromise happens gradually, we have a methodical way to transition to a new hash function. (Bitcoin) software can be written to start using a new hash function from a specific block number.

If ECDSA is indeed compromised, then Satoshi Nakamoto's legendary treasure, with a massive reward of up to 1.1 million BTC, attracts aspiring individuals worldwide to crack ECDSA. Who can say this is not another masterstroke by Satoshi Nakamoto back in the day? $BTC

🤔Do quantum computers pose a threat to Bitcoin security? Cryptographer Adam Back thinks so!

Recently, discussions about the potential threats that quantum computers may pose to Bitcoin security and the cracking of the founder's wallet have heated up again. In response, renowned cryptographer Adam Back has shared his views, suggesting that we are still decades away from the true era of quantum computers.

Back further pointed out that even if quantum computers become a reality, this may actually be a positive development for the Bitcoin network. Because Bitcoin can leverage quantum computers to upgrade and enhance its defense against quantum attacks.

Back also believes that if there is a possibility of quantum computers attacking the Bitcoin network, then there must also be methods to defend using quantum computers.

He emphasized that despite the extraordinary capabilities of existing supercomputers, the Bitcoin network remains one of the most secure networks in the world, and its computing power is the strongest globally. Therefore, the emergence of quantum computers may not be a threat but could allow the Bitcoin network to become even more secure through upgrades.

It is worth noting that the topic of quantum computers has recently become a hot topic again, primarily due to Google’s recent release of its supercomputer chip, coupled with exaggerated media reports, which have sparked some negative concerns in the community.

However, discussions about quantum computers threatening Bitcoin security have not ceased over the past decade, but the negative reports in these years have not had a substantial impact on Bitcoin's multiple market cycles and its current market conditions.

💬Do you think quantum computers will really pose a threat to Bitcoin security? What changes would occur if the Bitcoin network upgrades to counter quantum attacks?

Whenever the bull market falls back, someone always brings up "quantum computing" to make a fuss. In fact, $BTC has a mature "anti-quantum computing" solution, so there is no need to worry. $BTC reserves support for future post-quantum (PQ) signature mechanisms through Taproot leaf nodes, and there is no need to activate anti-quantum signature opcodes at present. The threat of quantum computing will not become a reality for at least a few decades, and anti-quantum signature technology will also launch a more compact and mature solution in the future. #量子计算机 #量子计算机攻破中本聪钱包

Quantum computers are coming, and in about ten to twenty years they could threaten Bitcoin? #量子计算机 #Bitcoin
