I'm looking at the "accountability" part a little differently. It's not necessarily going to be some built in rules in the coin that hold people accountable.

I'm looking at the "accountability" part a little differently. It's not necessarily going to be some built in rules in the coin that hold people accountable. Instead one of the critical philosophies I've adopted is "enable the people who hold the coin". The coin won't hold people accountable, the tooling needs to be available to allow people to hold other people accountable.
