Definition ∞ The quantum computation threat refers to the potential for large-scale quantum computers to break many of the cryptographic algorithms currently securing digital communications and assets. Shor’s algorithm, for example, could compromise public-key cryptography, while Grover’s algorithm could weaken symmetric-key schemes. This represents a significant future risk to existing blockchain security. It necessitates the development of new cryptographic standards.
Context ∞ The quantum computation threat is a pressing concern for the long-term security of cryptocurrencies and blockchain networks, prompting extensive research into post-quantum cryptography. The current discussion centers on migrating existing systems to quantum-safe algorithms before powerful quantum computers become available. This involves significant protocol upgrades and standardization efforts to safeguard digital assets against future computational advancements.
