Did Satoshi think that quantum computers will exist?

[serjent05]

Satoshi may be the creator of future technologies and currencies, but he is not a prophet, so he will not be able to know the quantum computer creates. But Satoshi has created a new world when adventurers can find their treasure when deciphering Blockchains, which is the best thing for many people.

He can think that it is possible for the technology to decode Bitcoin hashes and find private keys using the public key if Bitcoin technology will not improve but Satoshi is well aware that before that thing happen, developers will do their best to prevent it.  Bitcoin technology as we know is not stagnating.  There are several updates and  upgrades that happen to it and right now developers are also well aware of the possible threat this quantum computers to Bitcoin so they are already creating ways to improve Bitcoin security, that is for sure.

Move your coins from old addresses to make them quantum secure.
'Shalecoins', coins with no owner ' https://bitcointalk.org/index.php?topic=5134441.0 will be 'fracked'..

Quantum computers will surprise the Bitcoin community. The 'shalecoins' will be moved and will become active.

1. Yes, with quantum computers they would become active. Did Satoshi think that quantum computers will exist?

It doesnt matter. If all cryptography could be broken by quantum computers we will switch to quantun resistant cryptographic algorithms very quickly and believe me, Bitcoin will be one of the first  that will switch its algorithm because it will be critical to whole network.
Be calm, developers keeps their eyes on that too

Do you even know how long it will be before a first quantum calculation is made and a real use of quantum computing? These are not normal systems you have to teach them how to think and make connections in a specific case.

Even when there are functioning quantum computers they will have no software and it will take years to develop. They will be like those early computers in the 50s.
Your coins are safe and will be safe next year and the year after that.

I think that he predicted many things in ICT and development of all kind of technologies. Maybe he didn't know it will be called quantum computing or super computing but I think he definetely predicted development in that direction. If he wouldn't have been a visionare, he wouldn't create Bitcoin.

right on point! he may not think of quantum computers at the time of his BTC creation but for sure he thought of advance computers or any similar advance technology that will rise later on. he's not dumb to think that his invention would be the ultimate one!
 technology is continuously evolving and we are always in pursuit of more advanced, more versatile thing.so it wont be a surprise if someone will invent another thing that will make bitcoin obsolete!
but as of now, lets enjoy the benefits of having BTC and other alts in our age.

Back in 2009, Satoshi Nakamoto probably wasn’t overly concerned about advancements in quantum computing when he developed Bitcoin’s key encryption. Even now, quantum computing is still quite far off adoption levels that could be classed as mainstream, with only a handful of companies possessing the technology. But developments do mean that the threat that quantum computing poses to blockchains is starting to become real.

The scary thing is that the pace of development now means that it’s likely that quantum computers could soon break the 309 digit encryption that’s used across many modern systems today - including many blockchains.

[Lmaooo]

Quantum computers are not common, so it's too early to talk about anything. And besides, this technology has not yet been finalized

I think Satoshi knew about Quantum computing but he thought they're not coming any time soon yet still they're not in existence. And someday even if the quantum computers are active the bitcoin developers can actually implement another form of security to bypass them. People also get better with time just like computers do.

If he knew about Quantum computing, then he also knew that some day the early mined coins will be moved. And he didn't move these coins.

That means

2. Satoshi created the greatest prize competition and the privatekeys are somehow within the blockchain. https://bitcointalk.org/index.php?topic=5150688.0

and privatekeys are somehow within the blockchain = quantum computer?

[EdvinZ]

I think that Bitcoin developers can hypothetically be prepared for the fact that someone wants to use a quantum computer in the future to mine bitcoins and they will provide some protection against such calculations. And besides, the technology of a quantum computer is excessively expensive and difficult to implement, so that in the coming years we wouldn't seriously worry about it.

[threadsupport]

Well here in this article it said that quantum computers are very common right now and we cant stop that and we cant stop asking ourselves about it because quantum computers basically has purpose an atomic level calculations, and we somehow know that quantum computers will be exposed sooner or later.

Fully operational? i guess on some states maybe?

More likely private groups.

Nonetheless, becoming quantum-resistant, at least in terms of signature algorithms, is on Bitcoin’s roadmap as a necessary step, he added.

[Eugenar]

Satoshi has mined the most coins.
In 2010 they were talking about lost coins and Satoshi said

Think of it as a donation to everyone.

https://bitcointalk.org/index.php?topic=198.0

1. He thought the coins are lost forever and we have a lot of 'shalecoins' https://bitcointalk.org/index.php?topic=5134441.0 and they will become active one day

or

In 2011, Satoshi isn't have a concrete view of what quantum computer is, basically, he knows a bit of info, but to the fact that it can interfere with the blockchain and cryptocurrency, I don't think so. But even though we know there's a risk abiding the creation of quantum computer and the blockchain, blockchain is strong enough to become secure and safe from attacks since the hashes are distributed across many miners around the globe.

He makes it sound so easy.

Post-quantum cryptography calls for massively larger key and signature sizes. For example, a Lamport signature scheme would make transactions hundreds of times larger than now. It would be horrible for scaling.

Don't even get me started on the millions of lost or otherwise vulnerable outputs that won't be made quantum-safe by implementing a new algorithm.

As per experts, Quantum computers really becoming incredibly powerful, and it is more faster than Blockchain, but it is also believe that it will not break the blockchain industry, it will be hard to tell that right now and they can't see no real threat. If this will happen, it will count few decades before we can tell, so there is nothing to worry about for now.

It'll be crazy if that ever happens for sure, but it'll likely never be a possiblity due to just how hard to accomplish it is.

Regarding quantum computers, they where a basic concept during the time of Satoshi but i doubt it would have been an influencing one for him - they still look like they aren't coming around for a couple years, and we don't need to worry about it yet.

[crossabdd]

I think Satoshi already knew that. that someday a quantum computer will exist. but he also had predicted, when it will be finished. supposing when satosi made it with the support of a quantum computer. then what is created is a blockchain with a higher level of security. it's just when blockchain and bitcoin are created. it has no support by super computers. I'm still surprised. how he created that complicated security without a quantum computer. while to decode the code that is made is the computer's need. Does Satoshi have a hidden quantum computer?

[satoshyknew]

Satoshi knew that one day quantum computers will exist and will be able to move the early mined coins (P2PK) and created an unofficial prize competition to accelerate the development.

Maybe Satoshi created the greatest prize competition and the privatekeys are somehow within the blockchain.

Our guess is that he knew that the early mined coins will be moved one day. So he created a 'prize competition'. Otherwise he could move the coins to quantum resistant P2PKH addresses, but he did not and is not doing.

The only question is:

Who will win the race and get the early coins?

Quantum computing or solving the "Satoshi Prize Competition".

Nobody can stop that race.

[satoshyknew]

Satoshi knew that one day quantum computers will exist and will be able to move the early mined coins (P2PK) and created an unofficial prize competition to accelerate the development.

Nobody is asking why he is not moving the early mined unmoved P2PK coins:
These early mined unmoved P2PK coins are intented for an unofficial prize competition

https://bitcointalk.org/index.php?topic=175996.0

But he had other computers to mine and his own coins are unknown (P2PKH or P2PK not included in the above mentioned coins)

[hundredpercent]

* 100% sure that it is a prize competition
* 100% sure that you can solve it only with the blockchain
* still trying to solve it
* one day someone will solve it

[Ayiranorea]

Satoshi might have predicted about the growth of technology over the years. Right now the first revolution of quantum computers have come to usage. To what extent this gonna get continued is unknown. Satoshi on realizing the growth only have made the network much strong years back. Even now it is strong that the bitcoin network can't be broken by the quantum computer that have been developed by Google.
