Distributed ledger technology (DLT) refers to a digital system for recording transactions in a manner that ensures the security and tamper-proof nature of data across multiple sites. In financial applications, DLT is prominent in the implementation of blockchain, which allows for transparent and instantaneous record-keeping available to all authorized users. This technology improves transparency, reduces fraud, and enhances the efficiency of transactions, serving as the backbone for cryptocurrencies and other decentralized finance solutions.
