Quantum-Safe Blockchain

Definition ∞ A quantum-safe blockchain is a distributed ledger system designed to resist attacks from future quantum computers. It integrates cryptographic algorithms that are believed to be secure against quantum computational methods, particularly those that could compromise current public-key cryptography. This proactive approach ensures the long-term security and integrity of digital assets and transactions. It addresses a critical future threat.
Context ∞ The pursuit of quantum-safe blockchains is a growing area of research and development, driven by the anticipated threat of quantum computers breaking existing cryptographic standards. Efforts concentrate on evaluating and implementing post-quantum cryptographic primitives, such as lattice-based or hash-based schemes, into blockchain architectures. The successful deployment of such systems is vital for safeguarding digital finance and sensitive data in a post-quantum era.
