The Distributed Ledger Technology (DLT) or rather falls into the IT category of decentralized and distributed databases, i.e. systems in which all the nodes of a network have the same copy of a database, which can be read and modified independently from individual nodes. When enough nodes meet consensus regarding a transaction, the transaction is successfully confirmed; this is possible through special algorithms. The particularity of DLTs is that they are databases distributed on a global network and are based on cryptography.
