Miners are both in competition & forced to cooperate. An example of how this plays out is the public spat that broke out a while back between Gorillapool & TAAL, b/c TAAL was orphaning Gorillapool's blocks. Gorillapool wanted to build big blocks, but SOMETIMES (this is all about percentages, margins) when they made a big block, TAAL would take so long trying to validate it that they'd mine their own block instead first, snagging all of the transactions & the reward. Ouch. Gorillapool was of course pissed that this is happening, especially since they're small & struggling, & since uh TAAL desperately needs other miners to compete with to be actually doing what they say they're doing. So they were like, stop orphaning our fucking blocks, dude. In the end they worked it out--- as they have a strong incentive to do.
