In 10 years from now a quantum computer

[pixie85]

I read a lot of the article on this topic and it seems to me that a quantum computer will work in full force in 5 years.

And I don't think it will be this fast. When there were first Moon landings people were saying that a colonization of the Moon is just a few years ahead of us and then we will launch missions to other planets of the Solar System. We are decades later and there are no Moon bases or manned missions to Mars.

Many years will pass between the first prototype and a fully functioning quantum computer.

You forgot Satoshi's 1000000 bitcoins that have newer been moved, but still have their public keys visible.

Those addresses are difficult to protect from QC, because even if we implement a QC-resistant algorithm, those can't be protected or otherwise even Satoshi couldn't move them.

Actually once you soft fork to add the quantum resistant code, you might also add something to keep those coins locked forever. Something along the lines of: By the date the new code activates, coins not moved to a new wallet that supports it become locked.

we've had these discussions before and the consensus (i think) is that it's not ethical to steal/lock satoshi's coins. bitcoin users never opted into a rule system where their outputs would be forcibly locked after a certain time. i understand the motives to do it but a fork like that would definitely split the network. it's too politically contentious. it would be a different story if the protocol were designed that way from the start.

i'm sure we'll eventually fork to a quantum resistant signature scheme but the fork won't do anything to stop vulnerable coins from being spent. those coins will eventually be stolen over time.

It is a problem if we have quantum computers now, but no, it is still that early that we don't need to think about it by now.

I don't think developers will just let destroy Bitcoin like that, obviously, they will be ready when the quantum computers are already up. I mean I agree with some of the posts here to use and play with it because damn! Ready Players One will not be a sci-fi movie or a dream anymore.

Why there are suggestions that a quantum computer will be able to destroy the cryptocurrency?  What are the prerequisites for this?  In my opinion, if computer technology changes, then cryptocurrency technologies will also be improved.

Write that quantum computers will be able to crack any digital codes in a very short time, including picking up the keys to our wallets for cryptocurrency. Therefore, it would be more correct to point out that quantum computers will not destroy a cryptocurrency, but will make it defenseless. Of course, it remains to hope for the emergence of new technologies of protection or fundamental changes in the secret keys from the wallets of our cryptocurrency.

We will have a quantum secure network. That is not an issue, but the 'shalecoins', coins with no owner, will become active. https://bitcointalk.org/index.php?topic=5134441.0

And that will be the most challenging thing. https://bitcointalk.org/index.php?topic=5166180.0

The Q System One is a beautiful piece of engineering, but the quantum computing future is still a way off (by IBM

So i guess those will belong to those willing to invest in quantum computing, which is still so far much more expensive than any potential gains...

i believe that in 10 years bitcoin will no longer be minable (they will be finished), maybe we will all undermine bitcoincash or monero, however so much power makes an impression...

Mine-able yes, profitable no. There will always be a group of hobbyists willing to mine for fun, or with "free" (renewable?) energy available to do so. Also the asics are getting even more efficient, so Cannan's idea of embedding a few asic chips in common household appliances will return. Yeah, your smart fridge/ac/router/tv/heater/whatever might have 1~10 THs, why not?

Its like getting one of those usb mining sticks and plug it permanently into your "smart" tv, just because you want to help the community and it doesn't make you go bankrupt anyway.

I know i will probably get into that group, with a node as well, because its one way i can help and thank Bitcoin, for letting me eat today, when the politicians and institutions stole our wealth and nobody else cared.
