Quantum computing and Bitcoin: The collapse of security consensus is a hard flaw that Bitcoin cannot afford
With the development of quantum computing, people always ask whether quantum computing can crack Bitcoin. The answer is a very positive answer. The first step for quantum computing to move towards universal quantum computing is to solve the problem of factorization, which also means that Bitcoin can be cracked by quantum computing 100%. Its potential threat to the security of existing cryptocurrencies has sparked widespread discussion and concern. Especially for cryptocurrencies such as Bitcoin that are based on public key cryptography, the development of quantum computing seems to have sounded the alarm for "cracking". This article aims to explore the actual threat of quantum computing to cryptocurrencies such as Bitcoin, and analyze why this does not constitute the biggest risk facing cryptocurrencies.
