Can Quantum computer kill blockchain?

Recommended Posts

Do you think that quantum computer can kill blockchain and Bitcoin?

Google is working on this kind of technology and thy claimed to achieved quantum supremacy?

What do you think about this?

Yeah google said they achieved good things and i am sure they will make a tech that will change the world but nope it cant kill blockchain because Blockchain is a system that makes everything more safer.It will be used at different areas too.Lets see what will google make in the future.

I think if anything, a quantum computer could help block chain. It would process transactions and mine much faster. I don't see how it could kill blockchain, perhaps you can explain your reasoning?

Well maybe as you will study what can a quantum computer can do, it much more faster than any ordinary computers it has a powerful commutation process or simply quantum computing is the future of computers but i guess blockchain will not be dominated because it was part of the new technologies.

Exactly.
As we know that every encryption in past was cracked we can expect that somoene will invent computer that will crack sha256 and other encryption. We need to be ready for that and upgrade in time.

I believe that the main objective has been to promote non-control by governments and banks in general, to give freedom.

I don't think quantum computing would kill the blockchain technology. I think that it is a good idea that quantum computing could give boost on blockchain technology including bitcoin.

Quantum computing "feels" Bitcoin has a gap to attack, because each Bitcoin transaction accompanied by an unencrypted public key is exposed during the block confirmation period, which is about 10 minutes. The pause is enough for a quantum computer to hack a private key from a public key and steal stored funds.

Quantum computers are a threat to all types of digital security, where there is an application of public key cryptography in it. Blockchain also can not dodge, because there is an aspect of anonymity in it.

Hopefully everything can be prevented before its appearance because there are already many researchers who are preparing this.

Exactly.
Bitcoin hack is not th worst thing that can happen, as every single security in the world will be broken.
Military also uses same sha256 encryption, and many other security agencies also.
Quantum tech in bad hands can crash the whole world and not just blockchain

Yes it can because quantum computers 1000s times faster then nowadays computer. But i think the blockchain technology will improve and be more complex. Who knows...

Absolutely yes but it can help blockchain to improve its algorithms as quantum speed is thousands of times faster than a normal blocks of ledgers. Making blockchain more faster and secure will help future crypto users to focus on their coins and not worry about their earnings could be steal by others.

In short, perhaps, and maybe and maybe not. Quantum computers are really good in processing large datasets, because of the fact that the technology is based on manipulating near-limitless states of each variable in the algorithm. This means that a regular blockchain as it has been built today might be cracked much faster, and thus quantum computers might make current blockchain technology obsolete. On the other hand, quantum computers are really bad in cases, where the structure of the complexity in question is relatively unknown. This is how one can still "fool" a quantum computer.

What if google achieved quantum computing supremacy! They won't think about crypto currency or blockchain system rather they will invent new technology as the quantum computing is faster than super computer. However, google may rethink about the development of more faster blockchain. And it could be.

Quantum computing can be a big problem for cryptographic algorithms and also for cryptocurrencies. Google's announcement that it had reached quantum supremacy was received with skepticism, but still caused a drop of nearly 10% of the price of Bitcoin.

That's right. Why would they bother about blockchain technology when they claim they have the most advanced and powerful technology available in the world? If they are so good they will create something better

They don't care about blockchain ...we are talking about crypotgraphy here...
Bitcoin uses sha256 crypography same as military and security does.
Everything will be broken with quantum, not just blockchain

As google is the most powerful tech giant in the world they don't want let anyone or any technology to be better than them. They have a well established research center with hundreds of brilliant programmers and engineers where everyone remain busy in the development and invention of new technology. That's why they can able to find out quntam computing technology to defeat Satoshi Nakamoto's Blockchain system. But they took a long time. Shame on them. 

Don't worry, China will reply them soon. Hahaha 😊

Alas, Satoshi Nakamoto had disappeared! If he was alive than he must create more powerful block than quantum computing. Am i right? Just kidding 🤔

i read this on twitter. some of pro miners said it wont kill blockchain. but i can't find specific detail about this. maybe quantum computer can mine more fast, but what about the quality?

Defeat Satoshi's blockchain system with what purpose? Blockchain technology is great and is helping the world to develop faster so I don't think they have any reason to destroy it or do something bad against it

With Google having achieved quantum supremacy, cryptographers are racing to save blockchain—and crypto currencies.

A quantum computer is not yet in production, and as for the fact that a quantum computer will kill bitcoin, it is quite possible. Need to seek protection.

I think if Quantum computers exist then it really kills Blockchain and Bitcoin, it seems like now we have to discuss how to tame Quantum computer technology.

I think that later Blockchain will prepare a shield to protect himself. If there is danger it is certain that he will prepare for protection, I think Blokchain will do that.

If Quantum Computer exist now or in the future I think that's a real challenge for the Crypto Currency world because I'm 100% sure that it can bypass all of the cryptography. But I think Google won't do that, I hope.

That is good, that is the main motive in which quantum computer will not affect our crypto

    • Сам тоже думаю не садиться в этот поезд, а то пошёл там выполнять их задания в Гелакси и только сбои да сбои, надоело там раз разом крутить кнопку проверки. Почему всё так происходит не пойму, полностью отбили мотивацию.
    • Если их машина по сжиганию будет работать отлично, то и токен будет в будущем расти из-за сокращения его огромного количества. Пока как знаю дела в этом направлении идут не плохо, но рост конечно идут за счёт Битка.
    • Да это уж многих удивило, сам тоже увы не в теме, хотя крос у меня стоил 10$, если был бы 100$, то точно зашёл бы в тему с ремонтом, а там уже каждый день за 20 дайсов мог бы получать по 0.5$ за 20 секунд.  Кстати у вас всё ещё видны ваши кеды ? Их можно ремонтировать 🤔
    • Да, типа это пользователи так сделали, что форум на дне, а ведь с самого начала нужно было понять, что на одной оплата так далеко дело не пойдёт. Нужно было с самого начала работать над качеством пользователей и жёстче бороться с ботоводами, мотивировать на создание топиков, дать возможность размещать реф ссылки во всех разделах форума, в том числе и сокращение ссылки, подключить рекламу к форуму, если так плохо дело с подписанными. И это только начало списка, где всё это можно реализовать, но нет никаких действий очень долгое время.
    • Отлично, что и у вас получилось, теперь можно будет вникать в тему, где как заметил сами их квесты много времени не отнимают, ну кроме проверки. Сделал всё, оставил на час или вообще зайдёшь завтра и уже можно минтить поинты.
    • Если так будет, то шансов на успех скорее всего будет не многовато, когда рынок может пойти на дно и даже Лаунчпад на Бинансе особо то не сможет помочь проекту. Хотя будет надеяться на то что всё пройдёт хорошо и после халвинга не будет сильный спад рынка.
    • Из-за чего про них будут помнить ещё несколько сотен тысяч пользователей, которых они не хило кинули. А всё могло быть иначе, если разработчики распределились с дропом получше как и вообще самим листингом токена.
