Quantum Threat

Definition ∞ A quantum threat refers to the potential for advanced quantum computers to compromise widely used classical cryptographic algorithms, such as those securing internet communications and digital assets. Shor’s algorithm, for example, could efficiently break public-key cryptography. This development poses a significant long-term security risk to current blockchain networks and digital signatures. It necessitates the research and adoption of quantum-resistant cryptography.
Context ∞ The quantum threat is a growing concern discussed in cybersecurity and blockchain news, prompting research into post-quantum cryptography. While practical quantum computers capable of posing this threat are still in early stages, preparations are underway to upgrade existing systems. The long-term security of Bitcoin and other digital assets depends on finding robust solutions. This challenge influences future protocol designs.
