The Lightning Network is specifically designed to work around bitcoin design flaws. It entirely sidesteps the chain for a big part of the process. To me it proves that Satoshi did not, in fact, think of everything. Not the other way around.

> it takes less than one second to go through Like Bitcoin used to be before someone had the brilliant idea of destroy the possibility of zero-confirmation transactions on-chain with Replace-by-fee transactions

How does this work? I read the wikipedia article but I don't understand how Lightning enforces the transaction.

Lightning has mostly done this by being a lot more centralized in practice and one could argue... What's the point of it all in this case? Why not just use regular currency?
