Blockchain technology is very popular nowa- days.Blockchain means it is a chain of blocks where each block contains information.This technology was firstly described in 1991 by a group of researchers and it is also known as DLT means Distributed Ledger Technol- ogy.Beacuse blockchain is a distributed ledger and that can be accessed by anyone. The very interesting and important property of blockchain technology is once any data has been recorded inside the blockchain ,it is very difficult to make any changes on it.It uses the concept of decentralization and cryptographic hashing. In each block in the blockchain contains data,hash of the block,hash of the previous block.The hash of a block is the fingerprint of that block.If any data of a block is changed ,its hash also gets changed.
