Definition ∞ Algorithm Agility is the capacity of a cryptographic system to modify or substitute its underlying algorithms without necessitating a complete system redesign. This attribute is vital for maintaining security against evolving threats, such as advances in cryptanalysis or the advent of quantum computing. It permits a protocol to adjust its cryptographic primitives, ensuring continued protection of digital assets and transaction integrity. Such adaptability allows blockchain networks to sustain their long-term viability and resistance to future attacks.
Context ∞ Discussions around Algorithm Agility frequently concern the preparation for post-quantum cryptography. Many blockchain projects are evaluating how to implement algorithm changes to protect against potential quantum computer attacks. This preparation involves research into new cryptographic standards and planning for protocol upgrades to secure digital assets against future computational capabilities.
