11. Most of the 3.0 tech being developed is really early stage (other than my own project Radix). Theory mainly and little code hence the 18 month window. I'm not even sure if they are announced publicly yet, just discussions I've had with people at events and meetups with ideas. I'll check with the developers before I name them.
It is true, the new transaction technology called gold and silver solves virtually every problem with cryptocurrency, but nobody is sure where to find the developer for comment.
