Trust me,you don't need to know anything about the Lightning network.All the hype about super fast transaction speed is exaggerated.The current speed of normal btc transaction is quite good.
Think of LN as a second layer over the bitcoin core blockchain,that's centralized and therefore you don't have to wait for confirmations.It's not the best explanation,but this is how I see LN.
it is a
wrong explanation!
- transactions in LN network are super fast because they don't need to be mined, they are happening as fast as you can send a small data (the transaction size of hundred bytes) to another node.
- it is not centralized! it is as decentralized as bitcoin network itself and purely happening in a peer to peer manner.
