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.
I am only pointing out that "for many blockchain based crypto currencies" additional layers may be added, such as "mesh network transaction systems of the LN variety."
Thus it is INCORRECT to debate merits of LN vs BCH. It does not matter that people are trying to impress you that you should debate it that way, or that it is a valid comparison. You might consider those to be political motivations and arguments. They are not valid arguments from computer science or database theory.
