Man I have not paid attention to Blockchain since 2012 and WTF happened? How is it that the de facto way to try improving it is to make a new coin, and almost every coin I remember hasn't changed beyond what's required to keep functioning? Bitcoin has some thing called lightning to scale transactions which looks cool but seems to make it more complicated and doesn't solve the issues of PoW scaling centralizing the network and wasting more resources on making the difficulty value as high as possible. And now apparently Bitcoin blocks are out of transaction space, so I guess lightning isn't wildly adopted enough to scale Bitcoin? Is there some recap of the past 10 years because I'm lost as hell
