Post-Quantum Blockchain

Definition ∞ A post-quantum blockchain is a distributed ledger technology designed with cryptographic algorithms that resist attacks from quantum computers. It replaces current cryptographic primitives, such as elliptic curve cryptography, with quantum-resistant alternatives like lattice-based cryptography or hash-based signatures. The aim is to secure digital assets and transaction integrity against the theoretical threat posed by advanced quantum computing capabilities. It represents a future-proofed blockchain architecture.
Context ∞ The development of post-quantum blockchains is a critical area of research and engineering, driven by the anticipated advent of scalable quantum computers. Implementing these new cryptographic standards is essential for ensuring the long-term security and viability of decentralized networks and digital assets. This transition involves significant upgrades and standardization efforts across the blockchain ecosystem.
