There is often some confusion in distinguishing the difference between the distributed ledger technologies (DLT) and blockchain. It’s easy to see why this happens as the two terms are so often conflated.
One of the most common mistakes is to think that they are the same. As a matter of fact, DLT is an umbrella term used to describe technologies which store, distribute and facilitate the exchange of value between users, either privately or publicly, and blockchain is only one of them. Since it was the first fully functional DLT, blockchain is more well-known than other DLTs such as directed acyclic graphs (DAG). The SICCAR platform adopts DAG as it is more suitable for representing a range of complex use cases, where blockchain can be too linear. Therefore, in the same way, that the category “vehicle” covers the passenger car, the freight ship, and the space shuttle, the term DLT spans a broad set of technologies.
In summary, blockchain is one type of DLT (distributed ledger technology) while DLT as a term encompasses any data governed by consensus which is not centralised.
