Newbie question. When a block is cracked did others in the pool directly share work to crack that block? Im not sure if block mining is truly distributive, or statistically distributive, as in you only need one machine to find the block, and the more machines the quicker.
My understanding is that each machine is truly independent of each other. The concern I have is that if you have two machines, I don't think they collaborate so they can actually waste effort by trying the same solutions that did not work.
