“Split or Steal” is a UK game show. For those who didn’t know it, you can watch the following video. Two people reach the last stage of a game after beating all other competitors, and now facing a large amount of money. But they have to make a deal about how to distribute the prize. First, they do some “cheap talk” (link), trying to convince the other party that they are going to choose the “split” option, and they make their choices respectively and in private. The final moment is about revealing their real actual option. If both players choose “split”, they both get half of the prize.

All writes that go to the same block ID are considered overwrite (write over the same place).

However, duplicate writes are writes that have the same content, they may go to the same block, or they may not.

So, we cannot conclude the number of overwrites is greater than the number of duplicate writes, or the other way around. Generally, it’s much harder to identify duplicate writes than overwrites, because detecting content duplication requires manipulating a much larger amount of data.
