This is the fourth video from the Steemit 101 series. In this video I'm trying to explain what are witnesses and why it's important for you, as a Steemian, to know about that.

You can expect to find answers to the following questions:

• what are witnesses?
• what is a witness node?
• what's the difference between the top 19 witnesses and the runner-up witnesses?

Enjoy!
