The Lightning Network was literally the technology needed to enable Bitcoin to be adopted as legal tender at nation-state level.
El Salvador made bitcoin a legal tender in 2021, but the country has just adopted lightning network some weeks back. Lightning network makes bitcoin transaction to be cheap and faster which is the reason it was created. If there are more people making use of lightning network, also the mempool will be less congested if compared to if lightning network is not existing.
But did it really meet the public's demands is the question we should be asking ourselves. It's good enough that we have a premium option like that which would allow us to cheapen and hasten our transactions but if it was that good, why is the lightning network dying? It's because it's just not as amazing as it was made out to be in the past.
If we're looking for layer 2 solutions, we should look elsewhere besides the lightning network, the intent is great and the execution, I guess you can't say anything that's bad about it, but there has to be something off about it for people to not reliably and consistently use it for all their transactions cause let's face it, if it were the case we wouldn't have massive congestions like what happened when Ordinals was at a massive high in hype.
