I am thinking about pushing a Segwit patch to Bitcoin Cash github. Any chance it would be approved on time before 1 Aug?
You can try. I'm guessing you'll be met with an overwhelming chorus of NAKs.
Damn Bitcoin Cash Core ! They want to control everything! They are stopping real scalability for their own benefit!
Hahah.
On a more serious note: There are several other mechanisms that fix malleability. There is still a discussion to be had as to whether or not SegWit is the best approach.
Fixing malleability is important, but my predilection for Segwit goes much more far than that. It enables a whole new world of second layer and integration posibilities. Lighting Networks will be an AWESOME add... people focus on fee reduction but that's not the main point:
When I mentioned this, HostFat (who did Bitcoin Cash's ANN thread) said that they intended to add LN support with a future hard fork.
They haven't gone into details about this and I haven't seen a roadmap, but I don't think they're against it.
