When people see blockchain, the first thing they probably think of is cryptocurrencies and Bitcoin. No doubt blockchain has been thrust into the limelight by the unprecedented popularity of Bitcoin and the universe of cryptocurrencies, but blockchain is more than just a technology used in transactions.
Blockchain, simply put, is a distributed ledger of digital transactions whose records cannot be altered or destroyed, thus making them safe and secure. The closest analogy is that of transactions that people can see in their bank statement. Each transaction makes up a block in the chain.
