BRIEF STUDY ON BLOCK-CHAIN TECHNOLOGY

Abstract

Blockchain technology makes it possible to establish a distributed network without centralized control. Thanks to the use of cryptographic principles, transactions are both safe and reliable. Blockchain technology has become very fashionable in the latest years and has entered numerous realms, mainly because of the success of crypto-currencies. One sector where blockchain technology has great potential is health because of the need for a more patient-centred method to health systems and linking fragmented systems and improving the quality of telemedicine. The reason for Block-chain's importance is its core characteristics which provide protection, transparency and information transparency without any second party entity monitoring the transfers, thus creating important research areas, particularly from the viewpoint of technical problems and shortcomings. Blockchain functions as an unchangeable database that enables transfers to occur in a distributed way. Blockchain-based technologies are developing in many sectors, including finance, the credibility network and the IoT etc. An overview of blockchain technology is discussed in this paper
