I guess it's more so just the understanding of blockchain as a whole and the roles of the witnesses. I have a solid outline understanding of it- but that's all it feels like; an outline. I'm hoping to put some more time into researching it soon. The other thing is that I just don't feel like I know enough about a lot of the people running for witnesses and it kind of feels like jumping into politics with a load of candidates you know nothing about. But, again, I hope to spend more time learning about those aspects soon :) Thank you!
