Abstract

Distributed ledger technology offers a new approach in which data is stored and managed in distributed. Centralized systems are problem in terms of security, reliability and uninterrupted operation. Data keeping in single point causes center servers to become open to cyber attacks. In addition administrators of central servers or attackers can manipulate data. With the increase in the number of devices connected to the Internet, it is increasingly difficult for central servers to answer all requests. In order to solve all these problems, studies using distributed ledger technology are increasing. Distributed ledger technology, there is no single point of failure because the data is kept in a distributed and data can’t be changed by any participant. The system can operate uninterruptedly, no matter how high the transaction density as the participants can transact between each other without a central server. The first article describing the distributed ledger technology technically was published in 1991. The first widespread use is Bitcoin, which emerged in 2008. Bitcoin is without intermediary and secure payment system developed by Satoshi Nakamoto in 2008, when the global financial system collapsed. The popularization of Bitcoin cryptocurrency, studies on different sectors related to blockchain which is distributed ledger technology behind it have began. Blockchain technology due to the fact that is not sufficient in terms of speed and scalability, Hashgraph, Tangle, Holochain and Tempo distributed ledger technologies have been developed. In this article explains with existing distributed ledger technologies and defence, cybersecurity, insurance, supply chain, digital rights management, healthcare, energy and finance application areas.
