### The Future of Cryptocurrencies: Can They Adapt to PQC Standards?

[ykim240515]

As quantum computing advances, could existing cryptocurrencies like Bitcoin, which rely on SHA-256 and ECDSA algorithms, soon face significant threats? These algorithms were standardized in the early 2000s and provided robust security in the computing environment of their time, but were they designed with the quantum computing era in mind?

On August 13, 2024, NIST officially standardized Post-Quantum Cryptography (PQC) algorithms such as CRYSTALS-Kyber, CRYSTALS-Dilithium, and SPHINCS+. These new standards aim to address the limitations of traditional cryptographic techniques by being resistant to quantum computer attacks, but how might Bitcoin integrate these changes?

Why is it so challenging for Bitcoin to undergo a hard fork to adopt quantum resistance? Given that Bitcoin is a decentralized network, how could it achieve consensus among diverse stakeholders to implement such significant changes? Is there a risk of network fragmentation during this process? Furthermore, how could the technical complexity or the potential introduction of new vulnerabilities be managed when replacing existing cryptographic techniques with quantum-resistant algorithms? Additionally, what considerations should be made regarding the potential negative impact on Bitcoin’s performance, given that quantum-resistant algorithms might require more computational resources?

Amid these challenges, could it be more feasible for a new cryptocurrency, adopting PQC algorithms from the start, to emerge instead of modifying Bitcoin? Would a PQC-based cryptocurrency be able to maintain security in the quantum computing era?

OP, did you do any research in the forum before asking the question? I have lost count of the number of threads that have been created over the years regarding the identical (or very similar) quantum related questions. If you took a moment to look through the numerous threads you might have discovered that another one based on the same theories was not necessary.

Would a PQC-based cryptocurrency be able to maintain security in the quantum computing era?

I have reported your account for adding a hidden link in your completely off-topic and unnecessary post.

The market is always changing and there is competition. It is difficult to say whether it is an opportunity or a challenge. Each cryptocurrency follows its own rules of operation. Face it and turn challenges into opportunities.

This topic was indeed discussed many times on the forum (at least the general version of it, about Bitcoin and quantum computing). Cryptos can change if needed. For now, it doesn't seem to me like quantum computing is advancing strongly enough for it to be a big threat to Bitcoin. Even the science isn't fully there on quantum physics yet. When we get close, there will be tons of areas that would need to adapt and update their security. Bitcoin will be one of them, so I don't think it will be possible to miss that train.

Quantum technologies cannot be a threat to the bitcoin network because they are both independent of each other, we have to see bitcoin network as an advance system in which the blockchain technology has made it more easier to use and for it security performance in which is a reliable thing to behold, trust and security part of the decentralized network is what will make bitcoin overcome all the challenging obstacles it may face with any threat ahead.

Op has to know that they're two major thing ls to do in the forum and I think if you were a good reader, you would have seen those things from other posts but your motive is not to contribute and learn but to create nuisance threads. Op as it was said, if you want to grow, and don't know anything about Bitcoin and the forum as well, you are to learn from established members by reading their post and learn from there and in the process of reading you can make coffee moments if you understand the posts. And not you to create things you don't even understand. I saw one of your thread and you said you have gotten 0.1186448 BTC Bitcoin and asking again if that about can give you $3,000. Only this statement shows that you are novice in Bitcoin. If you not a novice and someone who has been investing in Bitcoin from little to 0.01btc don't know it in dollar. You just have to calculate the present amount of Bitcoin. Example: $58,000 x 0.1186448 BTC then times to you country currency rate with dollar exchange at the moment of calculating then you just get the amount your have. Humble yourself and learn and don't post trash.
