Quantum (NASDAQ:QMCO) computing has raised concerns about the future of cryptocurrency and blockchain technology in recent years. For example, it is commonly assumed that very sophisticated quantum computers will one day be able to crack present-day encryption, making security a serious concern for users in the blockchain space.
The SHA-256 cryptographic protocol used for Bitcoin network security is currently unbreakable by today’s computers. However, experts anticipate that within a decade, quantum computing will be able to break existing encryption protocols.
