BLOCKCHAIN IEEE PAPERS-2020



A blockchain is a digital record of transactions. The name comes from its structure, in which individual records, called blocks, are linked together in single list, called a chain. Blockchains are used for recording transactions made with cryptocurrencies, such as Bitcoin, and have many other applications.

A blockchain, originally block chain, is a growing list of records, called blocks, that are linked using cryptography. By design, a blockchain is resistant to modification of the data. It is an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way

How does a block chain work?
A Blockchain is a type of diary or spreadsheet containing information about transactions. Each transaction generates a hash. Each block refers to the previous block and together make the Blockchain. A Blockchain is effective as it is spread over many computers, each of which have a copy of the Blockchain.
