What is quantum technology?
Quantum technology can process an enormous amount of data and solve complex problems in seconds rather than decades.
Remarkably, quantum technology first appeared in the early 1900s. It originated from quantum mechanics, a branch of physics that examines how matter and energy behave at extremely small scales, such as atoms and subatomic particles.
In the real world, it’s applied in modern technologies such as transistors, lasers, MRI machines and quantum computers. These are said to be 300,000 times faster and more powerful than the ones used nowadays. Google’s new quantum chip, Willow, cuts computation times significantly and may provide hackers with the tools to unlock the algorithms that support Bitcoin and other cryptos.
Quantum computers could threaten Bitcoin’s cryptographic systems, including the Elliptic Curve Digital Signature Algorithm (ECDSA). Experts such as Adam Back and Michael Saylor argue that quantum threats to Bitcoin aren’t a concern at present because such applications require advanced quantum hardware, which may take years, if not decades, to develop.
Research and development of quantum computers is running at a fast pace, but is Bitcoin quantum-safe at this stage? Not yet, but developers are working to upgrade the network to mitigate possible quantum risks, including breaking encryption.
While it’s important to acknowledge the risks, it’s also essential to clarify that these are far from being actual threats for now.
Did you know? Albert Einstein made significant contributions to the development of quantum technology. He set the ground for quantum mechanics with his work on the photoelectric effect, which revealed what light is made of. He won the Nobel Prize for this, and not for the relativity theory, as many believe.
How quantum tech could break Bitcoin wallets
Quantum computing could significantly impact Bitcoin. This is mainly because it could undermine the cryptography that protects its network.
Quantum computing and Bitcoin (BTC) have been a hot topic for a while, and rightly so. It can disrupt the network and potentially break Bitcoin wallets by exploiting vulnerabilities in the asymmetric cryptography that secures them. Specifically, the ECDSA, the asymmetric cryptography used in Bitcoin, is vulnerable to attacks by quantum computers.
