Blockchain, the foundation technology behind Bitcoin, has gotten wide attention starting late. Blockchain fills in as an immutable record where trades happen in a decentralized manner Basically, a blockchain is a database incorporating a physical chain of blocks each of which is of fixed size that incorporate many transactions, where every transaction is added to another block is approved and after that embedded into the block.. Applications of blockchain are hopping up, covering different fields including financial organizations, reputation structure and Internet of Things (IoT), food industry, cyber security and many more. This paper is an introduction on blockchain innovation covering able issue for a tyro on blockchain advancement. The paper presents a layout of blockchain building directly off the bat alongside its different applications.
