Blockchain-Based Systems and Applications

Abstract

In block chain is a connection of records that records are known as blocks and the connection which connect this blocks are called cryptography. Each block contains hashing of previous block, in sequence of time of event. Block chain help the people to write the entries into a record of information. In block chain no one person can control the information. The most advantages thing in block chain that is provide a greater transparency it means the data on block chain is very much reliable and consistent and transparent. The second advantage which block chain provide as it enhance the security as it and there are many problems for single server to store all type of information, if all information gather in one server that is difficult for server to comprise all type of data.In today's scenario time is the big problems so it save our time as it increase the efficiency and speed as record keeping is performed using a single digital ledger that is shared among participants.
