Contest // Topic of the week №5 // How to explain to an ordinary person what blockchain is?

I can't successfully explain what a blockchain is, without making a detailed explanation of one of its uses which is as a LEDGER.
Though the blockchain has more uses, but it is actually popular because of its use as a ledger.
So from the explanation of what a ledger is, we can deduce and successfully throw a good light to what blockchain is.

Money is used for the payment of goods and services. In an organisation, when goods or services are sold/rendered, and payment is made, this is recorded in a book...which is referred to as a ledger. A ledger is an accounting book either physically or digitally that is used to record business transactions like payment using money.

The bank uses the ledger system of recording to make transaction simpler digitally. Money transferred from a particular location to another is made simple because of the ledger system.
The ledger records data of business transactions both digitally and with the use of books
But there was a need for transactions to be faster, done without third parties and at the comfort of people's homes. A better ledger system that was safe and could record transactions was needed.

This gave birth to the discovery of the blockchain.

With the definition of what a ledger is, A blockchain is a digital ledger that saves the data of a transaction especially business, between two different computers.
A blockchain acts like a digital ledger that saves the transfer of money 'basically cryptocurrency' from one node to the other.

Like I wrote from the beginning of the post, that there are many use to a blockchain apart from cryptocurrency, different types of information can be stored on a blockchain too. But the most known use is it being a ledger.
The blockchain is transparent and easy to trace data, it is safe to use while also being efficient and secured.

It is a digital storage that has brought cryptocurrency to where it is today. Its use has brought about decentralisation due to its advantages.
Blockchain is the digital ledger that is transparent, secured for every cryptographic transaction.

Thanks for reading my post, I do hope you have learned something about The Blockchain.

I invite @davidmarkgeorge, @imohmitch and @onlyonefave to participate.
