I was re-reading @michael_lwy 's explainer on MonadBFT and the problem of tail forking.

Tail forking is a massive problem for consensus algorithms descended from pipelined HotStuff. The possibility that a block will be tail forked disrupts any expectations of pre-trade privacy. In the extreme case, you get a remining of a block like in the Low Carb Crusader attack.

MonadBFT fixes this!
