What are the key challenges and potential solutions?
When it’s ain’t Bitcoin network, it just isn’t and that remains the main challenge of the LN as we have it today.
It remains a cross bridge, one that works eventually but, if many users subscribe to using it, well no and that’s largely because, it’s not originally a Bitcoin network.
Any possible solution,
I guess not. It’s just left for the people to come to terms with it and that’s it.
