DLT, or distributed ledger technology, refers to a decentralized system for storing and sharing data across a network of computers. DLT ledgers are a type of DLT that use a distributed database to store and manage data, such as financial transactions or other types of records.

One of the key characteristics of DLT ledgers is that they are decentralized, meaning that they are not controlled by a single entity or organization. Instead, they are maintained by a network of computers that work together to validate and record transactions. This makes DLT ledgers resistant to tampering or fraud, as there is no central point of control that can be exploited.

DLT ledgers also use cryptographic techniques to ensure the integrity and security of the data they store. This means that it is extremely difficult, if not impossible, for someone to alter the data on a DLT ledger without being detected.

There are a variety of different types of DLT ledgers, including blockchain, which is the most well-known and widely used. Other types of DLT ledgers include directed acyclic graph (DAG) ledgers and hash graph ledgers.

Overall, DLT ledgers are a powerful and innovative technology that has the potential to transform a wide range of industries, including finance, supply chain management, and healthcare. They offer a secure and transparent platform for storing and managing data, and have the potential to drive significant efficiencies and cost savings.
