This is one of the few problems that still could be counted as open problems in Bitcoin, called "Blockchain fork" or "Orphaned Blocks". there are a few implementations that could resolve this issue but none is perfect and none totally works. I liked the speech of Andreas M. Antonopoulos in Canadian Senate that asked to not to regulate bitcoin now, because there are things that quite don't work perfectly and now we are able to fix it with less loss than if it is adopted by many more (https://www.youtube.com/watch?v=xUNGFZDO8mM).

So it is a Protocol but still really young and immature in some senses, but it doesn't mean anything else, it is evolving almost everyday.
