Don't worry much about Quantum computers, because we still have more years ahead of us before it will be created. Practice a safe way of sending your coins to a newly generated address and don't reuse the same address. However, I believe that the devs are working on how to generate a script that will be quantum resistance before that time.

Which experts? give us names, source of information.

Just please, don't link us to AI generated articles.

According to Tether CEO Paolo Ardoino, quantum computers are still a long way from being able to break bitcoin's cryptography, i have read various articles regarding this but are not at hand atm.

Quantum computers need to reach at least 1 million qubits to be able to threaten bitcoin instead of 10-20 million as before. But meanwhile, the most powerful quantum computer today is IBM's Condor, with 1,121 qubits.  And as far as I know, quantum computers have been researched and developed since 1980, which means after 27 years, they have only achieved 1,121 qubits. At that rate, how many years do you think it will take to reach 1 million qubits?
The 20-30 year time frame is a fairly conservative prediction, as at the current rate of development, quantum computers could take much longer to get there.

By the way , Bitcoin uses the SHA-256 algorithm, which is also the algorithm that banks, corporations , and even governments are using to protect confidential information. If quantum computers can threaten bitcoin, traditional systems will suffer the same fate as bitcoin.

The rate of development increases exponentially, not linearly, so judging future progress based on what has been achieved so far is incorrect.
There are engineering problems that take years to solve, then it’s just a matter of scaling and further optimizing the technology for the consumer market.

You can observe this technological progress in every field. Take cars, for example: 20 years ago, 500 hp and sub-4-second times to 100 kph were reserved for exotic supercars. Today, you can find these numbers in family wagons and SUVs, while exotic cars have moved to 1,000+ hp and sub-2-second times to 100 kph, even with all the ecological restrictions imposed on them.

And how long have cars been in development? Since 1885?

We are not at the technological peak, we are still cavemen who have barely stepped out of the cave, and the snowball has just started to roll.

Let's not forget that there is no formal mathematical proof that SHA-256 is unbreakable, only strong evidence that no efficient attacks are currently known.
With the current advancements in AI, which may soon (or already) be smarter than us, new threats to breaking these cryptographic assumptions may arise.


Yes, but banks and other entities you pointed out can recover faster and upgrade more easily, as they are centralized and do not lose much business in the process.
Bitcoin would lose a significant portion, as people would lose trust in it, and it is neither easily recoverable nor easy to upgrade (hard fork).

Wallet security doesn't matter in this case. In the near future, QC may take over your coins by deriving the private key from the public key.

If that's  the way you saw that news I.e "Bitcoins will not be safe once we have powerful quantum computers", then regard it as a  clear FUD spread ..
By then  Bitcoin would have found a way around it and   besides  not all Bitcoin,  just about 25%  and those are addresses which already expose their public key.. Most of it will be related to P2PK address as they already  expose theirs when you send to it but for others it's  only when you spend out.. this is why avoidance address reusage  was hammered on  I.e if you eventually  spend from an address and you still receive on it later  you could be vulnerable if and only when QC can derive private keys to spend  coins from public keys, it's  not also good for privacy anyways (address re-use)!

Yeah, quantum computers are indeed powerful computers that have the ability to potentially break the cryptography that Bitcoin uses, and this is something that can actually put people's Bitcoin at risk.
But some projects are actually working on using different kinds of cryptography that will be resistant to the power of the quantum computers. For example, some are actually looking in hash quantum cryptography or even other post quantum digital signature techs. If this is achieved, then the safety of crypto will be guaranteed, even with quantum computers around.

There is no problem with storing Bitcoin. You can safely store your Bitcoin in any solid hardware wallet or wallets like Electrum. Quantum computers are not a threat, nor will they be anytime soon. Even if such an epoch-defining technological revolution does happen, Bitcoin will find solutions to protect itself against it. As other members have written in the thread, there is no need to be afraid. Don't trust and don't be one of those trying to spread FUD.

You guys can scrap some topics in the past. This bitcoin talk is a gold mine for us who are here, we can definitely have a lot of information since there are topics that has been discussed by the core developers and Satoshi himself in the platform in the early years of BTC. People are too scared of this quantum tech but we're more advanced tbh and core developers are preparing for this, and we still have a lot of time before everything upgrades, we just need to chill out. AFAIK, devs are designing a new address type which is P2QRH (pay-to-quantum-resistant-hash) which is called BIP-360. I don't know yet if this is feasible but you can read and verify here: https://bip360.org/
