Quantum computing and mining

1. < UL >

in the current situation, quantum computers can't help with bitcoin mining.

turning to quantum computers will not affect the mining speed, because with the soaring price, the difficulty of mining will increase.

indeed, The introction of quantum algorithm will put the traditional cryptocurrency system at risk

the influence of quantum computer on the mining of special currency

at present, we do not have such quantum algorithm, but what should we do if we find it in the future? As we all know, bitcoin aims to identify the speed of mining, and also increases the difficulty of mining. It means that the difficulty of finding the algorithm will become more complex

in fact, it is impossible to mine with ordinary computers, so miners use ASIC chips to dig bitcoin. At present, there are two kinds of cryptocurrency, RSA and elliptic curve cryptocurrency. In fact, these two cryptocurrency methods are vulnerable to quantum computer attacks. According to Anastasia, we only need 2500 cubits to interrupt algoant, interrupt EC, and about 4000 cubits to interrupt RSA

Hackers can identify bitcoin wallet addresses

in the current situation, hard forking is impossible because many users have lost their wallet addresses and coins. Now, the worry is that quantum computers can easily help track lost wallets, and hackers can use them to decrypt and retrieve such lost coins

However, the main focus is the research of quantum computer. The entry of such computer system will make the cryptocurrency system face risks. The system could be the destroyer of bitcoin

2. In fact, the threat of quantum computers to bitcoin is not mining, but trading attacks. We know that the transaction of bitcoin is completed by decentralized cryptography authentication, and the core of this authentication method is hash algorithm. If there is a quantum computer, it can create collisions (Grover algorithm, polynomial acceleration) to forge transactions for profit. Because the core algorithm of bitcoin has been fixed, if the algorithm is not changed, the key length cannot be increased, and this attack cannot be resisted. However, if there is a practical quantum computer, what can we do is better than this kind of attack...

3. Quantum mechanics reveals that particles have volatility and uncertainty. Two particles appearing in the same event have ghostly entanglement. Scientists have realized long-distance transmission of particles by using quantum entanglement. How far is it from our long-distance transmission? At present, this technology is not mature. But quantum mechanics also has other potential value, that is, what is the difference between the quantum computer we are studying and have initially realized and our ordinary computer? How powerful is its computing power? Absolutely beyond you<

internal structure of quantum computer

this is the internal structure of a quantum computer. The precision parts made of these golden brass parts are completely different from the computers we see in our daily life, but the operation core of quantum computer still uses binary code

binary code

binary code is a computer language composed of 0 and 1, that is, bits. The smallest unit in the information set is bits. The computer simply breaks the information into the smallest combination, and then transforms them very quickly. Quantum computers also use bits, But different from the traditional bit, it can be converted to 0 or 1 at any time, because quantum is a superposition state, which can be either 0 or 1. Quantum bit is more flexible

flexibility of electrons

when electrons are mixed together, they rotate clockwise or anticlockwise continuously, which means that qubits are also mixed together, one represents 0 and the other represents 1, so qubits can complete many phase tasks at the same time! This means that we can accomplish computing tasks that we couldn't have imagined before. In theory, we can use anything to make qubits, such as electrons or atoms. Qubits are at the core of computers. They are super concting circuits made by quantum technology and can run in two directions at the same time. Because qubits have such excellent multitasking characteristics, if we can find a way to make them come together to solve problems, then our computer power will be multiplied
why can quantum computers have such powerful capabilities
If a person is trapped in a maze, what he has to do is to find a way out as soon as possible, but the problem is that there are too many forks and too many dead ends! We have to go to every road, as soon as possible to find a way out, through too many detours, encounter too many dead ends, finally lucky to find a way out, this is the way of traditional computer computing! Not a good try! Although they deal with it very quickly, they can only deal with one task at a time, just like people in a maze can only explore one way at a time!

4. Yes, this is true of most systems that rely on cryptography, including traditional banking systems. But quantum computers don't exist, and maybe not in the near future. When quantum computing is really about to become a threat of bitcoin, we can use the post quantum algorithm to update the bitcoin protocol. Based on the importance of this update, it is reasonable to believe that developers will review it repeatedly and finally accept it for all bitcoin users
