Protocol-13 could be the best choice for Stellar in its development, but I'm sure that Stellar will get a clash from competitors of a Stellar type of coin.
That is why because it is certain that Stellar is also facing threats from various altcoins, Protocol-13 is difficult to realize if only the Founder of Stellar just paused without taking action.
I am still hoping for the progress of Protocol-13 from Stellar, which is the first time I have seen it.
