Quantum Resilience

Definition ∞ Quantum Resilience refers to the ability of cryptographic systems and digital assets to withstand attacks from quantum computers. As quantum computing advances, it poses a threat to current encryption standards, making the development of quantum-resistant algorithms a critical undertaking. Ensuring quantum resilience safeguards the long-term security of blockchain technology and digital assets.
Context ∞ The present discussion surrounding Quantum Resilience in the crypto space is primarily focused on the transition to post-quantum cryptography (PQC) standards. Debates frequently involve the selection of appropriate PQC algorithms, the timeline for implementation across various protocols, and the potential performance trade-offs associated with these new cryptographic methods. Future developments to monitor include the standardization of PQC algorithms and the practical integration of these solutions into existing blockchain architectures.
