Both of them are about risks against Bitcoin. The first one is technological. Recently, the National Institute of Standards and Technology NIST. said it is time to start promoting migration to postquantum cryptography, because. will weaken the asymmetric cryptography of SHA256.
We are talking about an attack of 51, but in that case it will take ten or twenty years a 99 attack. One bad actor with a quantum computer will be spending much less energy than anyone else, and will acquire 99 of the hashing power. If it is 99, it is not an attack. You realize that?
Yeah, it is a monopoly. Well, not necessarily. Very quickly That is the first question? Yes. So do we change the algorithm?
Move to proofofstake? Things like that. The second question is about the corporations. and governments, who will not be happy with Bitcoin.
Oh no, Bitcoins community will need to respond. Any ideas about this? Okay, great.
First question, quantum cryptography and more specifically quantum cryptanalysis. At some point, quantum computing will exceed the of current cryptographic algorithms. Listen, that is part of cryptography. You have twenty to thirty years of usable life cycle. an algorithm before it is due to new developments in mathematics and technology, etc.
Bitcoin is such that it can be upgraded both the signing algorithm and the hashing algorithm can be switched. for other algorithms if we think there is a need to do that. Quantum represents a threat only if it is unevenly distributed in commercial sectors. But if quantum and cryptanalysis is available only to one actor, mostly likely they are a state actor and they will not use it on Bitcoin., they will keep it secret and use it at a time when they are threatened, such as. by a cryptographically secured nuclear weapon or whatever, some crazy like that. Certainly, what weve seen with intelligence agencies that have computing advantages, they dont use it until there is a dire emergency, and Bitcoin is not a dire emergency.
Once you use it and everybody knows you have it, then all the algorithms will be changed. You have one shot, so you better make it good. If quantum computing is available broadly, then miners upgrade to quantum computers and use quantum SHA. CroisSHAntum. Something like that.
I dont know. We would change the algorithms. If there is enough availability of quantum computing that 99 of mining capacity switched over, the chance. the chance that it will be controlled by one person is pretty slim. everybody to run quantum SHA, and it will be a transition like when we went from.
FPGA to ASIC. We will see a different order of magnitude or several orders of magnitude improvement. Keep in mind that running a quantum computer is neither free nor easy, right?
It will be expensive in terms of energy and cooling costs. The electricity that you are not spending . will be spent on keeping the at 200 degrees below zero. All of these things add up.
We dont know what the economics will be. I try not to solve problems until problems come up. Bitcoin is very much a system where we solve problems when it is necessary to solve them. We will see.
As for the second corporations and governments not being happy, Im sure that they wont be happy. I believe this is the where people decided that the King wouldnt be too happy with their choices. Kings were not happy anywhere, and yet the revolution happened anyway. Bitcoin is a technological revolution. It is a global system.
Corporations and governments must adapt to new technology. They have been adapting to new technologies for hundreds, sometimes thousands, of years. They will adapt to Bitcoin, which is neither the worst thing nor the most insurmountable thing to happen. There could be far worse cryptocurrencies than Bitcoin from the perspective of governments. But the fact that governments will not be happy really doesnt concern me much.
Bitcoin is a system that does not require their permission, approval, cooperation, endorsement, or assistance. It is a system that simply exists now. can deny that it exists, but it still exists. can pretend it will go away, but it isnt. We can talk all day about whether the government should or shouldnt regulate Bitcoin. The difficult question is whether governments can regulate Bitcoin.
The answer is simple: they cant. They cant regulate Bitcoin itself. They can regulate the edges, the behaviour of some users within their borders, under certain circumstances, but the truth is that they cant really regulate Bitcoin itself. Governments and corporations will need to adapt. I think that is a feature of Bitcoin, not a bug.
I think that is one of the reasons why Bitcoin is so exciting to a lot of people. It introduces a new choice. It is not saying you cant the old way, in hierarchical organizations, restricted within one border and jurisdiction, and banking with a central bank.
You can still do all of those things. But we will also do this and see which one is better. That is really the bottom line.p
