Crypto executives say that a quantum attack on cryptocurrency may not be immediately identifiable as such. According to the founder of Quantus, bad actors with access to a cryptography-breaking quantum computer will not try to announce it to the world by hacking high-profile Bitcoin wallets, such as those belonging to Satoshi Nakamoto.
Instead, the first quantum attack on cryptocurrency will likely appear as an ordinary security breach, making it difficult to detect. This is based on reporting from CoinTelegraph.
The concern over quantum attacks on cryptocurrency is related to the potential for quantum computers to break certain types of encryption used to secure cryptocurrency transactions.
