The blockchain is an undeniably ingenious invention – the brainchild of a person or group of people known by the pseudonym, Satoshi Nakamoto. But since then, it has evolved into something greater, and the main question every single person is asking is: What is Blockchain? Is Blockchain Technology the New Internet? By allowing digital information to be distributed but not copied, blockchain A blockchain , originally block chain , is a growing list of records , called blocks , that are linked using cryptography . Each block contains a cryptographic hash of the previous block, a timestamp , and transaction data (generally represented as a Merkle tree).

Abstract—A blockchain is a distributed ledger in which par-ticipants that do not fully trust each other agree on the ledger’s content by running a consensus algorithm. This technology is raising a lot of interest both in academia and industry, but the lack of tools to evaluate design and implementation decisions may hamper fast progress.
