No. Blockchain is the technology that enables the existence of cryptocurrency. A blockchain is a digital ledger of transactions that is distributed across the entire network of computer systems. Think of it like a ledger that shows the entire history of that piece of currency.
To put it simply, it is a system of recording information that makes it impossible to hack the system. Each block in the blockchain contains several transactions, and every time a new transaction occurs on it, a record of that transaction is added to every participant’s ledger.
A blockchain database can store a large quantity of information that can be utilised and accessed by many users at the same time.
But what makes Blockchain unique is that it is not owned by a single person or entity— making it more secure and trustworthy. The idea is that because no one controls the blockchain, they cannot take over and rewrite the records.
