Yes, blockchain terminology is confusing, frequently dense and guaranteed not to come up in party conversation, unless you are at a Consensus convention.
But should you find yourself asked about blockchain and want to answer in a way your grandmother would understand, consider some of The Onion’s many questions and answers:
Q: What is the benefit of using blockchain?
A: Provides a more efficient way for you to lose all your money at once.
Q: Is the system fully secure from hackers?
A: Nothing that bad has happened yet, so we’re just going to say yes.
Q: How do banks feel about blockchain technology?
A: As long as banks still find a way to exploit the poor, they couldn’t care less.
