What is Distributed Ledger Technology (DLT)?

Distributed Ledger Technology (DLT) refers to a shared database upon which transactions and associated details are recorded in multiple places simultaneously. An example of DLT could be in the form of a permissioned network under control by a central authority, or a permissionless network maintained by a decentralized network of nodes lacking a central authority. Blockchains and Directed Acyclic Graphs (DAGs) are both examples of different types of DLT.
