Would Quantum Computer Kill Bitcoin

[panganib999]

As per the latest, Google has reached Quantum Supremacy. Meaning it could potentially decode an entire blockchain and...
YOUR PRIVATE KEYS...
Blockchains are secured through elliptic curve cryptography (ECC), just like encrypted user data and website traffic. Now the issue is that ECC is NOT "quantum-safe" meaning that a quantum computer could theoretically decrypt a user's private keys and forge transaction signatures.
Is this the end of Crypto?
I don't think so, but I'd love to hear your opinions too! (Especially the opinion of a cryptographer)

Spreading news, articles, or anything about quantum computing going to crush down blockchain because of  its ability of decrypting private keys and breaking blockchain supported security might affect bitcoin's reputation and users for it might deploy panic and scare to investor, traders and users. Because one of  the biggest asset of bitcoin is the anonymity it gives to every transaction and user's addresses, and losing it might affect bitcoin big time. But, this claim could not be possible if people behind blockchain will take an action to counter the threat.

i hope thats not will be reall... bitcoin have grow in the world...

Very likely, but it takes more time! Quantum Computer is too expensive at the moment! Not suitable for trying to find private keys

I am sure that the Bitcoin network will find a way out of this problem in the coming years and will have very reliable protection against quantum computing. Bitcoin will always be ahead and the most innovative and secure.

Quantum computing can pose a problem for Ellyptic curve cryptography in the future. Bitcoin in a way already has some sort of safe guard against this. As a precaution, if you do not use the same bitcoin address more that once, it makes it extremely difficult to  crack your private keys. In any case, bitcoin is community-driven and a better security layer will be implemented when ECC becomes practically vulnerable. Quantum computing cracking encryption is not just a bitcoin problem, it will affected more serious segments such as military defense systems, finance etc

Yups because bitcoin is design for future and only a quantum computer can kill this so what’s the sense of having this?i am sure this won’t happen and we still have time to prevent this from happening

i hope thats not will be reall... bitcoin have grow in the world...

Yeah it won’t ,let’s leave this to the experts than can make this not possible

The strength of crypto is its cryptographically secured ledger which can't be viably breached at this point. Quantum computers will make it economically viable to break the cryptographic algorithm which will make blockchain obsolete in case some updating isn't done to fight it. So, the fear is legit that quantum computers will kill BTC. But it is way too far from reality as of now.

*heavy sighs*

This quantum computer will definitely destroy bitcoin, altcoins and even blockchain if the Government will successfully made this in the future (I hope they don't), even if quantum computer are just still theories, it scares me because we're saying goodbye to the foundation we made with bitcoins and other cryptocurrencies. Imagine the government having this, they could easily manipulate and control the entire blockchain or even destroy it.

Disclaimer: Let's withdraw all of our cryptocurrencies into fiat before this happens (let's pray for blockchain)

from some of the media that I read, Google and IBM have made quantum computers but are still small scale, around 50-60 qubits. while the bitcoin blockchain has a qubit of around 100, so at the moment the bitcoin blockchain cannot be solved. but it could be possible because in calculations it would take another 10 years to create a quantum computer that could break the Bitcoin Blockchain. so I think one day bitcoin will be hacked (broken code) because it has obsolete technology.

I can't be sure clearly but in my opinion, Google's quantum computer doesn't have much impact on bitcoin because the supremacy of quantum computers only shows that quantum computers can solve very complex mathematical problems and mathematical problems are actually not the same as the context cryptography on the current blockchain.

They are reports that quantum computer has nothing to do with bitcoin it is just a rummor got spread on internet in reality it has nothing to do with bitcoin

Blockchain system will improve, and bitcoin will do as well. and there is no possibility that quantum computer will help us. because quantum is easily to control and everyone will not blessed to have this expensive system. who can have this is those multi-billionaire campany's. and its not suitable for everyone's need especially in crypto industry. no need to worry about this advance quantum computing system.
