But such features could be found in many implementations other than LN.
And these could be layered on top of many coins - for example, Bitcoin Cash....not just Bitcoin.
I thought SegWit capability was a mandatory requirement for the Lightning Network?
Bitcoin Cash has not activated SegWit. Therefore I don´t think the Lightning Network
would be able to function on top of Bitcoin Cash.
Why would they deploy a solution like the LN anyway? Their whole narrative is based around
how on-chain scaling is the superior solution to scaling Bitcoin. If they would introduce a 2nd layer scaling solution
they would lose their main value proposition.
LN only requires tx malleability fixes from segwit. There are other ways to skin that particular cat.
As regards BCH deploying an LN like solution - why not? As long as users are given the choice to continue to use Layer1 as before, then L2 solutions can be developed that offer real value propositions to users and their intended use cases.
What BCH wont do is force the issue by making the L1 solution unusable.
