On Federico Razzoli's YouTube channel Richard mentions how he does not have time to explain transactions (at around 30min): [https://youtu.be/2eaQzahCeh4?t=1800](https://youtu.be/2eaQzahCeh4?t=1800) I know the code is commented and there is text based documentation, but I think it would be interesting and useful to have Richard walk through at a high level how transactions work. Richard, is this a possibility? Would any one else be interested in this also?
