What is blockchain?

A blockchain is a type of distributed database or blockchain technology is an advanced database mechanism that allows transparent information sharing within a network. A blockchain database stores data in blocks that are linked together in a chain. In other words blockchain is a decentralized, distributed and public digital ledger that is used to record transactions across many computers so that the record cannot be altered without the alteration of all subsequent blocks.

How it works?

Each block in a blockchain has a block number and a timestamp according to the order in which it is added to the blockchain. Also, every block is added to the previous block through hashing. The hashing gives each block a unique number that acts as its digital signature.
