Post-Quantum Ledger

Definition ∞ A post-quantum ledger refers to a blockchain or distributed ledger technology designed to resist attacks from future quantum computers. Current cryptographic algorithms, such as those used for digital signatures, could potentially be broken by sufficiently powerful quantum machines. A post-quantum ledger incorporates quantum-resistant cryptographic primitives to secure transactions and maintain the integrity of the network against such advanced threats. This represents a proactive measure for long-term security.
Context ∞ The development of post-quantum ledgers is a critical area of research and engineering within blockchain technology, driven by the anticipated threat of quantum computing to existing cryptographic standards. News reports may cover advancements in quantum-resistant cryptography and its integration into new or existing blockchain architectures. This ongoing work is essential for ensuring the enduring security and trustworthiness of digital assets and decentralized systems in the coming decades.
