Why Blockchains Matter

Blockchains make moving and storing digital assets possible – whether that’s recording a change of ownership for someone’s real-world assets or sending a friend the $20 you owe them. 

But keep in mind – crypto transactions can’t be reversed, and there’s no middleman to call. That’s a feature of blockchains, not a bug. 

Most blockchains don’t have a corporation or CEO controlling things. Anyone can join or contribute, and power sits with the users in the network. With no single controlling voice, blockchains are resilient – and very different from traditional businesses.

And there isn’t just one blockchain. There are many, each built for a different job. If you’re using more than one, it’s worth knowing that their features and costs can vary. 

So that’s blockchains – secure digital record books. Now let’s see if you can keep your entries straight in the quiz.
