Greetings @ddangerwu. the technical terms of the structuring of the chain of blocks are new to me and you have a simple way to explain it, it will be of great help to me when applying it in a programming language, so I will be reading your future articles.
As for the Lightning network protocol, in my opinion it is a plus that bitcoin needs to generate confidence to those who just know the currency, these transactions can facilitate mass consumption such as restaurants, shops, etc.
