What is Blockchain?
A blockchain is a constantly growing ledger which keeps a permanent record of all the transactions that have taken place in a secure, chronological, and immutable way.

Let’s breakdown the definition,

Ledger: It is a file that is constantly growing.
Permanent: It means once the transaction goes inside a blockchain, you can put up it permanently in the ledger.
Secure: Blockchain placed information in a secure way. It uses very advanced cryptography to make sure that the information is locked inside the blockchain.
Chronological: Chronological means every transaction happens after the previous one.
Immutable: It means as you build all the transaction onto the blockchain, this ledger can never be changed.
A blockchain is a chain of blocks which contain information. Each block records all of the recent transactions, and once completed goes into the blockchain as a permanent database. Each time a block gets completed, a new block is generated.

Who uses the blockchain?
Blockchain technology can be integrated into multiple areas. The primary use of blockchains is as a distributed ledger for cryptocurrencies. It shows great promise across a wide range of business applications like Banking, Finance, Government, Healthcare, Insurance, Media and Entertainment, Retail, etc.
