Hi Richard, thanks for your time, I really appreciate it, but I'm still unclear on how this works.
So uberblocks point to the MOS. Why do you then require multiple uberblocks? Or are there actually multiple MOS'es? Or is there one MOS and multiple delta's to it (and its predecessors) and do the uberblocks then point to the latest delta? In the latter case I can understand why Nullifying the latest uberblocks reverts to a previous situation, otherwise I don't see the difference between "Nullifying the first uberblocks" and "Nullifying the last uberblocks".
