to be honest that roadmap looks more like a start of development thing where we all where expecting a close to release thing…
i think have a very small core dev team boomerang us now with way slower release cycles then other big chains thats why we move out of top 20 because we develop like top 100 and not a top 10 coin in terms of development progress and team resources.
so im here with mixed feelings the stuff u plan to do sounds good just we where expecting it to be released soon and not end 2019 a first version with many things coming not before 2020.
jump on lightning 2020 might be only a cool thing if u mean cross blockchain lightning with hybrid nodes that run BTC and XEM and maybe other coins that taking part in an cross chain lightning network
POS+ and new supernode ruleset will also be a make it or break it point because 400x 3 million coins is a big part of total coins by fuck up supernodes in future ecosystem u would enourmous destabilize XEM
but lot things can not be judged by just read a one sentence about it and not get access to deeper details
the details can make this way better and more promising in best case (or worse in bad case…)
