It is believed that future quantum computers will significantly outperform traditional systems in terms of processing power. Some analysts think this evolution will make itself felt in a decade or so. These predictions are making Bitcoin aficionados feel nervous, and here’s why.
The factorization issue is one of the major pitfalls in this context. Quantum algorithms, such as Shor’s algorithm, may be capable of cracking RSA encryption. In theory, this might undermine the security of digital signatures used in blockchain platforms.
