ChainCatcher news, the World Economic Forum (WEF) recently issued a serious warning that central bank digital currencies (CBDCs) may be vulnerable to decryption attacks by quantum computer systems.
Quantum computers are still largely in the experimental stage. Various proofs of concept already exist, and a few laboratories claim to have solved quantum system customization problems that traditional binary computers cannot solve in a reasonable time. But to a large extent, it will take a long time to truly achieve.
WEF mentioned this danger in a blog post on May 21, saying that "central banks must embed encryption flexibility into CBDC systems to defend against quantum network attacks on payment infrastructure."
