The main purpose of Lightning Network is to address scalability. More specifically, providing a much higher transaction throughput at reduced fees through payment channels. An intriguing concept, especially when considering Bitcoin’s current throughput and fees situation. With the transaction costs mounting several times this year alone, a cheap solution will have a lot of merit. However, Bitcoin Cash provides a similar functionality and some added features.

Both systems work completely different, to say the least. Secondly, people claim the Lightning Network will only work for small transactions. That is the main objective, granted, but people can still use Bitcoin for larger amounts. Bitcoin Cash has no real advantage here either, despite its “unlimited” transaction size.

The Lightning Network still doesn’t require actual network confirmations like Bitcoin Cash does right now.  Moreover, BCH has no unlimited transaction size either. Right now, it appears to be capped at 24 TX per second, which isn’t exactly stellar either. 

In the end, people are free to use whichever solution they like best. From a technical point of view, the Lightning Network and Bitcoin Cash are nothing alike whatsoever. There will always be squabbles between BCH and BTC supporters, that much is evident. The Lightning Network is an exciting development, although its actual sue cases have yet to be determined.
