Cryptocurrency faces a quantum computing problem
Quantum computing is typically feared due to its potential to render bitcoin obsolete by cracking its cryptography. However, one analyst alleges that there may be a much simpler way to do it: by beating bitcoin at its own game. Almost instantly following this news, a fervor of panic erupted within the crypto community. Talks of obsoletion were on the table, and conversations as to how to combat this new quantum threat were discussed at length. Though, for the most part, anxieties subdued, and the hyperbole was seen for what it was, that is until the aforementioned Medium post was published.
However, the since-deleted post got a few things wrong. First, the calculation made by the author suggested that 1 BTC was produced every 10 minutes. This is wrong. In actuality, the network currently yields This miscalculation alone would throw the theory out to some degree already. Yet, there are other glaring omissions. The post fails to include the difficult readjustment which occurs every blocks.
Still, in reality, the likelihood of bitcoin network being able to produce a difficulty setting of this level is improbable. Nevertheless, the author is right in a sense.
Any attempt from a quantum computer to mine BTC could credibly result in the denigration of the network. Regardless, the notion of Sycamore or any other quantum computer targeting cryptocurrency is pretty ludicrous. Besides, Andreas Antonopolous, a bitcoin advocate who has been relatively vocal on this subject, suggests that bitcoin is not the issue we should be worried about.
If we get quantum computers that can do thousands of qubits without a correction and consistent results, we have a much bigger problem.
In order to defend against any threat, worldwide communications would have to be upgraded to a quantum-resistant standard. Ironically, this is far easier for cryptocurrencies than it would be for global communications systems. Featured Image Credit: Photo via Pixabay. Related Articles. You Might Like. Ads by Cointraffic.
Quantum computers could crack Bitcoin by 2022
A Quantum physicist is revealing that while quantum computers pose no risk to Bitcoin mining, they threaten the algorithms that keep Bitcoin and the internet secure. In a recent video, Anastasia Marchenkova argues Bitcoin has a built-in design that protects it against entities using quantum algorithms to mine BTC at a rapid rate. Bitcoin is designed to adjust the difficulty if we mine blocks too fast. So even if we found this quantum algorithm, the difficulty would just get harder. However, the quantum physicist warns that quantum computing poses a serious risk to cryptographic algorithms which keep cryptocurrencies and the internet at large secure. Both of these are vulnerable to attacks by quantum computers which means a large enough quantum computer will be a problem for anyone online…. There actually is a quantum algorithm to break RSA and elliptic curve encryption.
How I Cornered the Bitcoin Mining Market Using a Quantum Computer (Theoretically!)
Grover's algorithm confers on quantum computers a quadratic advantage over classical computers for searching in an arbitrary data set, a scenario that describes Bitcoin mining. It has previously been argued that the only side-effect of quantum mining would be an increased difficulty. In this work, we argue that a crucial argument in the analysis of Bitcoin security breaks down when quantum mining is performed. Classically, a Bitcoin fork occurs rarely, i. The situation differs dramatically when quantum miners use Grover's algorithm, which repeatedly applies a procedure called a Grover iteration. The chances of finding a block grow quadratically with the number of Grover iterations applied. Crucially, a miner does not have to choose how many iterations to apply in advance. Suppose Alice receives Bob's new block.
Who Will Mine Cryptocurrency in the Future - Quantum Computers or the Human Body?
Two cutting-edge technologies that promise to revolutionize entire fields may be on a collision course. Cryptocurrencies hold the potential to change finance, eliminating middlemen and bringing accounts to millions of unbanked people around the world. Quantum computers could upend the way pharmaceuticals and materials are designed by bringing their extraordinary power to the process. Here's the problem: The blockchain accounting technology that powers cryptocurrencies could be vulnerable to sophisticated attacks and forged transactions if quantum computing matures faster than efforts to future-proof digital money. Cryptocurrencies are secured by a technology called public key cryptography.
Quantum computing could eat bitcoin for lunch but regulation can save it
By Dr. Money requires copy protection. If banknotes or coins could be forged, they would hardly be usable in daily life. Blockchain technology has been proposed as a new way of preventing double-spending in digital currencies because they have advantages over traditional centralized systems, i. But, a radically different approach can be made using quantum mechanics.

From dramatic price swings to regulatory uncertainties, headlines concerning cryptocurrency make it easy to forget that, despite the technological milestones that blockchains and cryptocurrencies have achieved, fundamental technical loopholes remain open to exploitation by future technologies, such as quantum computers. Even though quantum computers will not wipe out blockchains and cryptocurrencies entirely, experts agree that quantum computing will bring significant security risks to cryptocurrencies as a whole. Google reported that Sycamore had the capacity to compute a mathematical equation in seconds that would otherwise take a supercomputer 10, years to compute. Experts agree that this technology is the start of an arms race to develop powerful quantum computers and that quantum supremacy may arrive sooner than originally expected, prompting some further questions: Will quantum computers eventually crack the code of cryptographic algorithms, such as SHA and elliptic-curve cryptography? If so, what is the future of cryptocurrencies?
