Is there any rationale for LN?<p>As I understand the situation: Bitcoin has a hardcoded limit for the number of transactions that can be processed every 10 minutes. Having such a limit is a good thing, because nobody can stress the network with an unlimited number of transactions. But the limit should be close to the normal usage of the network. So the hardcoded limit should rather be a setting that gets updated from time to time.<p>So there are the Bitcoin Unlimited guys who propose a client that has a setting for the limit.<p>And there are the LN guys, who propose a whole new layer on top of Bitcoin. Why?
