What is a Blockchain?

A Blockchain is a peer-to-peer public ledger maintained by a distributed network of computers that requires no central authority or third party intermediaries. 

A Blockchain consists of three key components:


- a transaction, 

- a transaction record, and 
- a system that verifies and stores the transaction. 

The blocks are generated through open-source software and record the information about when and in what sequence the transaction took place. This β€œblock” chronologically stores information of all the transactions that have taken place in the chain, thus the name blockchain. In other words, a blockchain is a database of immutable time-stamped information of every transaction that is replicated on servers across the globe.
