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

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

The question is important for the future of Bitcoin.
Imagine a BTC price > $1,000,000 and more than 1,000,000 'shalecoins', coins with no owner https://bitcointalk.org/index.php?topic=5134441.0 would become active.
The value of these coins would be > $1,000,000,000,000
How can that work?

I think we should know what is the quantum computers first? And I think this video is the most understanable information way.

https://www.ted.com/talks/shohini_ghose_quantum_computing_explained_in_10_minutes?utm_campaign=tedspread&utm_medium=referral&utm_source=tedcomshare

If you know what is the quantum computer now. Then you may understand it is not possible to know this things 10 years before.

There are two important.

Ad 1. If quantum computing managed to break private key cryptography in a way that it allowed somebody to control shalecoins, this would instantly induce a panic which would crash the price of bitcoin, so it wouldn't be $1,000,000,000,000 anymore, more like $1,000.

Ad 2. If quantum computing managed to break private key cryptography, we would have much bigger problems than future of bitcoin - all of the internet would be exposed to attacks it would be easy to hack anything from internet banking to medical equipment. Pure chaos would ensue and not many people would worry about their cryptocurrency.

Satoshi's caliber and knowledge in IT, cryptography and all sorts of techy stuff is immense, and we can see that through his own post writings here in this forum and other places in the internet that it's not impossible that he had already thought of quantum computing as one problem bitcoin might face in the future hence he 'future-proofed' the whole protocol by embedding lots of hard to break algorithms and cryptographic keys in it. Though it's still entirely possible that quantum computing would break bitcoin, it would take a long time for it to happen and perhaps by then, we have moved into a more secure algorithm or we may not even exist at all.

The thing here is... If a quantum computes could vuln bitcoin by brute force, that would mean the end of sha256 (but it's impossible), that's why they call it one-way encryption. And if it really happens there are other things to worry about than bitcoin. Because in the scenario where a quantum computer decode bitcoin transactions, then we will see a fork to recover the coins and an encryption upgrade, so, don't worry at all Wink

Well Bitcoin could easily Transition into a fork that generates a new quantum proof private key (we don't know if the current one is or is not) and you'd move your coins to your new address.

Shale coins could still be a possibility but is it an issue? Thought gone coins coming back to circulation? Would it even be profitable to run a quantum machine for the length of time it takes on average to crack?

If he did, he wasn't worried about them. That's why early outputs weren't P2PKH (pay-to-pubkey-hash) but rather P2PK (pay-to-pubkey). P2PK outputs provide no protection if ECDSA is broken by quantum computers. From the Bitcoin wiki:

Quote
Obsolete pay-to-pubkey transaction

OP_CHECKSIG is used directly without first hashing the public key. This was used by early versions of Bitcoin where people paid directly to IP addresses, before Bitcoin addresses were introduced. scriptPubKeys of this transaction form are still recognized as payments to user by Bitcoin Core. The disadvantage of this transaction form is that the whole public key needs to be known in advance, implying longer payment addresses, and that it provides less protection in the event of a break in the ECDSA signature algorithm.

It will be at some point. It's also entirely possible for this to happen even before quantum computers are commercially available.

"Recovering" someone else's coins is a very slipper slope. What essentially happens is that you steal them in place of another thief.

Yes he did and that is why he developed the whole Bitcoin protocol in such a way that the difficulty would adjust, based on the combined hash rate at any given time. This was done to make room for any future technologies that might want to dominate the mining scene, when they develop something that would make it easier to mine bitcoins. <ASIC technology is just one example of that and the difficulty increased based on the added hashing power that was added by this technology>

Quantum computing might replace ASIC technology, like ASIC technology replaced GPU mining.  Roll Eyes

This was discussed many times in the past.

He basically mined to a public key, which is slightly less secure than a Bitcoin address so its slightly easier to crack. So he didn't really worry about quantum computers back then.

Most likely if it reaches a point when Quantum computer "could" crack a public key and find the private key, then there will most likely be an upgrade to the network to prevent peoples funds from being stolen.

But from what I heard we are about 10 years away from this happening at the earliest.

Satoshi Nakamoto is a mathematician. I am a physicist. I had  a mathematics professor that could be compared with Satoshi Nakamoto. When bitcoin was invented in 2009, the quantum adventure was at its beginnings.

I made my PhD thesis on quantum wells (in 2000), in 2009 what was in my PhD thesis was learned in the QM in the 2nd year of faculty.  When bitcoin was invented no one could say that Quantum Computers will be invented in 10 years.

Thus, Satoshi Nakamoto did not think that quantum computers will exist when he invented the bitcoin.

Hmmm... quantum proof private key cryptographic algorithms exist? As far as I understand there is no such thing?

A bit of a stale topic since even the most optimistic projections give us another decade before such a qc becomes a viable threat... And it is conceivable that Bitcoin would have upgraded significantly by then... Considering the developments of the last decade alone.

I do wonder if all that presumed upgrades would also be retrospective, it would have to be otherwise people who didn't update wallets would risk losing everything.

A quantum secure network / addresses are possible and not an issue. But what will happen to the 'shalecoins'?
Maybe some will say to burn them in the new quantum secure network, what would lead to a fork.
And some would still use the new quantum secure network with all the old coins.

Ad 1. If quantum computing managed to break private key cryptography in a way that it allowed somebody to control shalecoins, this would instantly induce a panic which would crash the price of bitcoin, so it wouldn't be $1,000,000,000,000 anymore, more like $1,000.
And the Bitcoin ecosystem would be broken. The Bitcoin community should not allow this and we have to solve that problem now.
The best solution would be, somebody could move the 'shalecoins' to P2PKH addresses.

https://securityboulevard.com/2019/08/the-race-is-on-crypto-agility-vs-quantum-computing-who-is-ahead/
Each passing day brings the world closer to the exciting reality of powerful quantum computing...
But one thing is foreseeable: along with this greater power, some of today’s foundational crypto algorithms will be broken by quantum computers, making data security in a post-quantum world a top concern...
And although post-quantum is projected to be a few years away, an enterprise must start planning today to be post-quantum ready...


a few years away... $ billions investments...

http://www.washdiplomat.com/PouchArticle/cms/index.php?option=com_content&view=article&id=785
...Italy, he says, is “attached to the European initiative,” a 1 billion euro investment in quantum research. Other nations are pursuing similar initiatives. The United Kingdom, Japan and Australia have invested upward of $100 million per year in quantum information technology. In 2018, the United States’ National Quantum Initiative Act instituted a $1.2 billion investment into quantum information science. In doing so, the U.S. joined Canada, the European Union and China as a leader in world quantum investment, with respective commitments of over $1 billion.

maybe earlier:

They will develop new quantum technologies:

"Quantum computers will soon outperform classical machines"
"The project is part of the EU’s €1 billion, 10-year Quantum Flagship initiative to kickstart a competitive European industry in quantum technologies."

New quantum computing building block developed by Australian researchers
The quantum building block, which is capable of performing an operation of 0.8 nanoseconds, is around 200 times faster than existing spin-based two-qubit gates in silicon.

Forget Qubits — Scientists Just Built a Quantum Gate With Qudits
And they could help usher in the era of the quantum computer.

The research team discovered that four qudits had the same power as 20 qubits. What’s more, the qudits were more stable than the qubits.
