Distributed Ledger

Definition ∞ A distributed ledger is a database that is shared and synchronized across multiple participants or nodes in a network. Each participant holds an identical copy of the ledger, and any updates are replicated across all nodes through a consensus mechanism. This shared record-keeping system forms the foundational technology for many cryptocurrencies and blockchain applications.
Context ∞ Distributed ledger technology, particularly blockchain, is a subject of continuous development and discussion in news related to digital assets and their underlying infrastructure. Innovations in consensus mechanisms, scalability solutions, and the application of DLT in various industries are frequently reported. Understanding the principles of distributed ledgers is fundamental to comprehending the operational integrity and security of decentralized systems.
