Distributed Ledger Technology (DLT) is a system for recording and sharing data across multiple locations (or nodes) without relying on a central authority.
DLT refers to the technological infrastructure and protocols that enable the simultaneous access, validation, and updating of records across a network that is spread over multiple entities, locations, or nodes.
In a distributed ledger, every node in the network participates in processing and verifying each item, ensuring accuracy and generating a consensus on the validity of the data. This creates a shared and synchronized database that is transparent and tamper-resistant.
DLTs can be used to record both static data, like registries or identity records, and dynamic data, such as financial transactions or asset movements. Among the various implementations of DLT, blockchain is the most well-known example — popularized by cryptocurrencies like Bitcoin and Ethereum, but now used in industries ranging from finance to healthcare.
