Abstract

The Block chain is basically decentralized technology and Block chain has distributed ledger that secure and transparent transactions without using central authority. mostly block chain developed for Bitcoin. Blockchain has initially used different applications in multiple industries like healthcare, finance, supply chain management. This paper presents a basic study of block chain Technology including basic block chain architecture, consensus mechanisms,and operation flow. This also gives real world applications.
