"The little boy in the movie, Charlie and the Chocolate Factory, is looking for a golden ticket inside candy bars. Charlie is a like a miner. And the golden ticket, which will grant him a tour of Willy Wonka's factory, is like the block reward. Now suppose that by searching for this golden ticket, Charlie is also simultaneously validating purchases of candy bars and recording them in the factory's business ledger-the Willy Wonka blockchain. And suppose there are many Charlies all around the world doing the same thing, searching for that golden ticket. As they open Wonka bars, they are auditing the Wonka blockchain and checking one another's work. Willy Wonka's contest has miraculously incentivized children around the world to work together to validate and record transactions of Wonka bars, helping Willy keep track of who paid for what, thereby protecting his profits and ensuring that his factory stays in business and can continue to make chocolate for everyone."
