DISTRIBUTED LEDGER TECHNOLOGIES (DLTS): EVOLUTION, DIFFERENCES, SIMILARITIES AND ADVANTAGES

The new information and communication technologies (NICTs) have been changing the way of life and work of people and organizations. Among these emerging technologies, some have been highlighted as for example: Artificial Intelligence, Big Data and Distributed Ledger Technologies (DLTs). DLTs are the basis of cryptocurrency, the most famous of which is Bitcoin, based on Blockchain technology. The purpose of this article is to present the differences, evolution, similarities and advantages of DLTs. For this a brief description of the main DLTs is presented. Finally, a comparative analysis has been made. The methodology used was the performance of a systemic search by the key words Blockchain and Tangle. Subsequently through an exploratory research the study was expanded including Ethereum, Hyperledger and Hashgraph. The result was a timeline and two tables that allowed to identify the evolution, differentiation and similarities between the DLTs studied.
