Quantum Computing Threatens Blockchain Security, Warns EU

EU regulators have issued a warning about the potential security risks posed by quantum computing to blockchain technology. According to the European Supervisory Authorities, advanced quantum capabilities could compromise the cryptographic methods that protect blockchains, potentially before any commercially viable application reaches the market.

The authorities emphasized the importance of strengthening preparedness and monitoring risks tied to quantum computing across the EU financial system. This warning covers not only blockchains but also cryptography used for communications, transactions, databases, and other applications.

While a timeline for when these risks may materialize is unclear, supervisors and market participants are expected to take proactive steps to mitigate potential vulnerabilities.
