Bitcoin has several attack vectors that can be exploited by a quantum computer. Various algorithms, such as Shor’s algorithm (for integer factorization) and Grover’s algorithm (Search), pose significant threats to the Bitcoin protocol. These algorithms can potentially enable cryptanalytic (brute-force) attacks on different aspects of the known protocol. I can identify three areas with vulnerabilities […]

Quantum computing systems are gearing up
The big question is how will they change things? Here is a small introduction: Quantum computing is built upon the principles of quantum mechanics and computer science. Today, many are familiar with algorithms such as Deutsch-Jozsa, Grovers, Shor´s, QFT algorithms which were actually invented back in the 1990s. However, they are starting to have a […]
Let´s talk qubits
Quantum computing – a whole new way of crunching numbers that’s like nothing you’ve seen before. At the heart of this amazing leap forward are these tiny things called “qubits.” Unlike regular computer bits that are either 0 or 1, qubits can be 0, 1, or both at the same time. It’s like they have […]
Keys, Custody and the Basics.
A basic principle in understanding wallets for your digital assets is custody. Before explaining custody let´s talk about private keys – read this great explainer. A private key is a 256-bit number that can be represented in several ways like a hexadecimal number or 64 characters, but there are also smaller formats as seen in […]
Stablecoins and preserving value
Many talks about “So-Called Stablecoins” or CBDC and refer to them as Fiat money. How stable are these coins actually and what if you look at a longer period of time. Most people would of course not want to lose money when they have worked hard and earned money, so you would assume to put […]
