So I understand that each person has 30 votes for Witnesses. These can be voted once and left for as long as you like and revoked as you wish.
So I've been trying to figure out how people decide who to spend their votes on? What criteria did you use to determine how to vote? Was it just random to the first places that asked you? How important are these votes and what value are they to those who get voted for? What am I really doing by giving someone my vote? What the heck is a "witness node", some actual physical server a witness needs to run?
Do I have the basic idea correct even? I have seen plenty of posts that talk about Witness related issues, but I am looking for the baby version so I can crawl before I walk. I would appreciate some discussion.
Thank you!
