Forget Bitcoin — What Is the Blockchain and Why Should You Care?

Imagine that you’re walking down a crowded city street, and a piano falls from the sky. As dozens of people turn to watch, the piano crashes down right in the middle of the street.
Then, without a second to lose, every person who witnessed the event is strapped to a lie detector and recounts exactly what they saw. They all tell precisely the same story, down to the letter.
Is there any doubt that the piano fell from the sky?
This is the principle behind the blockchain, a powerful and widely misunderstood invention that could profoundly affect our relationship with the digital world.
