There is a mistaken notion that a Bitcoin miner producing orphaned block is a flaw. Most mathematicians & computer scientists see this as a fault that needs to be fixed. Quite simply, this is false.
What they failed to understand or perhaps refused to, is that Block orphaning is part of the Bitcoin grand design. It is a signalling technique that enables miners to understand the efficiency of their investment in the system. The orphaned blocks indicate that they have to improve their infrastructure.
