A blockchain is a distributed database which is used to maintain a continuously growing list of records, called blocks. Each block consists of two sections; one is timestamp which contain the update time information and another contains a link to the previous block. A blockchain is a managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once a block is recorded the data in the given block cannot be altered without the altering all subsequent blocks and collusion of network. On functional point of view, a blockchain can serve as “an open, distributed ledger that can record transactions between two parties efficiently and effectively and in a verifiable and permanent way. The distributed ledger itself can also be programmed to trigger transactions automatically.”


The first blockchain was conceptualized by Satoshi Nakamoto in 2008 & implemented as a component of the digital currency which is known as bitcoin. For bitcoin the blockchain act as a public ledger for all the transactions. Through the use of peer-to-peer network and a distributed timestamp server a blockchain database is managed autonomously. Bitcoin is a use case of blockchain. Blockchain made the bitcoin the first digital currency which solves the problem of double spending without requiring a trusted administrator.
