Distributed Ledger Technology (DLT) is a term used to describe the technological infrastructure used for recording different types of transactions where the transactions and their details are recorded across multiple nodes (network participant computers) at the same time. Distributed ledgers do not have a central data store or administration functionality, unlike traditional databases. The more distributed, the more immutable the data becomes as no one entity has access to change the data record across all the nodes.

There is a common misconception that distributed ledger technology and blockchain are the same thing, however, blockchain is just one type of distributed ledger.
