Listen to Matthew Kratter's Bitcoin University viddie on YT. He dopes it out in full detail.
Discussion
I've seen enough videos on that channel. I pretty much agree with him, but he also wastes a lot of time in his videos ranting

This is a dumb part of one of those videos
Why would miners follow Cores direction on this?
There are other problems with the video, but I'll keep watching

Kratter is a trader, relying upon him for technical explanations is quite foolhardy.
