Why Quantum Computing Is Already a Danger to Digital Currency
Imagine how easy it would be for one computer to crack the encryption protecting our money. That is the threat Central Bank Digital Currencies (CBDCs) face due to quantum computing, and the quest to protect them is already underway. Quantum computers pose a huge threat to the encryption used by Central Bank Digital Currencies (CBDCs) and other digital infrastructure. This is because the mathematics that currently underpins encryption technologies like public-key cryptography (RSA and ECC) relies on problems that are nearly unsolvable for a traditional computer, but which would be effortlessly shattered by a powerful quantum computer using an algorithm like Shor's algorithm. How a Quantum Attack Would Work Most digital security, such as a CBDC, is built on a public-key infrastructure (PKI) where an individual has a public key…
