We all know what the blockchain is and how it is related to bitcoin or other cryptocurrencies, but how would you define it to someone who has never heard the word 'blockchain'?
Here is one I find easy
' The blockchain is a global and decentralized ledger that stores information about a transaction and also verifies the data'
What is you own favorite definition or explanation?
If I had to explain the blockchain to a technically illiterate person, I would first tell them that it is a transparent, public ledger that is decentralized and is untamperable. You can't fudge the numbers because the blockchain makes a solid effort establishing public trust. It is accessible anywhere there is an internet connection.
People need to know that the blockchain technology is scalable and puts a new spin on existing tech, with a simple yet complex set of protocols.
